Moving home mortgages: a complete guide

Moving home is exciting, but it can also feel like a lot to manage at once. You may be selling your current property, searching for your next home, checking your mortgage options, reviewing your equity and working around a property chain.

Your next mortgage may not simply be a repeat of your current one. You might be able to port your existing deal, switch to a new lender, borrow more for a bigger property or reduce your borrowing if you are downsizing. The right route depends on your income, deposit, equity, current mortgage, moving costs and the property you want to buy.

This guide walks through how moving home mortgages work, what happens to your current mortgage, the options available, the costs to plan for, and the key checks to make before you move.

What is a moving home mortgage?

A moving home mortgage is the mortgage you arrange when you buy your next property and move from your current home.

In many cases, your existing mortgage is repaid when your current home sells. You then arrange a mortgage for the new property, either with your current lender or a new lender. However, the exact route depends on your current deal, your lender’s rules, your equity, your new property price and how much you need to borrow.

Some movers are able to port their current mortgage deal to the new property. This means taking the same mortgage product with you, subject to lender approval. However, porting is not automatic. Your lender will still need to check your income, affordability and the property you want to buy.

Other movers choose to switch to a new deal instead. This may happen if their current mortgage has ended, if a new lender offers a better fit, or if they need to borrow more than their current lender will allow.

The key point is that moving home is not just about replacing one property with another. Your mortgage, equity, deposit, borrowing needs, costs and timeline all need to work together.

In simple terms

A moving home mortgage can involve:

• repaying your current mortgage when your home sells
• porting your existing deal to your new property
• borrowing more if your next home costs more
• switching to a new lender or mortgage deal
• reducing your mortgage if you are downsizing
• checking whether early repayment charges apply

Muttuo Mortgages can help you compare these routes before you commit, so you can understand which option may suit your next move.

What happens to your current mortgage when you move?

When you sell your current home, your existing mortgage usually needs to be repaid. In many cases, this happens on completion day, using the money from your buyer.

Your solicitor receives the sale funds, repays your outstanding mortgage balance and then uses the remaining equity towards your onward purchase. If you are buying and selling at the same time, this all needs to line up carefully so the sale, purchase and mortgage funds move through the chain on the same day.

However, what happens next depends on the type of mortgage you have and the route you choose for your new home.

You may repay your current mortgage and start a new one

This is a common route when moving home. Your current mortgage is paid off when your property sells, then you arrange a new mortgage for your next property.

This may be with your current lender or a different lender. The right option usually depends on your interest rate, product end date, early repayment charges, affordability, deposit and the mortgage deals available when you move.

You may be able to port your mortgage

If your mortgage is portable, you may be able to take your current mortgage product with you to your new property. This can be useful if your current rate is lower than the deals available now or if you want to avoid an early repayment charge.

However, porting is not guaranteed. Your lender still needs to approve the new property, check your income and reassess affordability. If you need to borrow more, the extra borrowing may be arranged on a separate product with a different rate and end date.

You may need to pay an early repayment charge

If you leave your current mortgage deal before the end of its fixed, tracker, or discounted period, an early repayment charge may apply. This can be a high cost, so it should be checked before you make decisions around selling, porting or switching lenders.

In some cases, paying the charge and moving to a new deal may still make sense. In others, porting or timing your move around your product end date may be more suitable.

You may reduce or clear your mortgage when downsizing

If you are moving to a cheaper property, you may be able to reduce your mortgage balance or pay it off completely. This can lower your monthly payments, reduce interest costs and release cash from your current home.

However, it is still important to check whether early repayment charges apply and whether you want to keep some savings aside for moving costs, repairs or future plans.

The main thing to check

Before you start viewing properties seriously, check:

• your outstanding mortgage balance
• your current interest rate
• your product end date
• whether your mortgage is portable
• any early repayment charges
• how much equity you may have after selling costs

These details can shape whether you port, switch, borrow more or reduce your mortgage when you move.

How moving home mortgages work

A moving home mortgage usually works in stages. You first check your current mortgage and equity, then work out what you may be able to borrow for your next property. Once you have found a home and had an offer accepted, you can submit a full mortgage application.

The process can overlap with your sale, property search, legal work and chain. That is why it helps to understand the main steps before you start making offers.

Check your current mortgage first

Start by reviewing your current mortgage balance, interest rate, product end date and any early repayment charges.

This helps you understand whether it may be better to port your mortgage, switch to a new lender or wait until your current deal is closer to ending. It also gives you a clearer view of how much of your sale proceeds may be available after your existing mortgage is repaid.

Estimate your equity

Your equity is the difference between your property’s estimated value and your outstanding mortgage balance.

For example, if your home is worth £350,000 and your mortgage balance is £220,000, your estimated equity is £130,000. However, the amount you can use towards your next move may be lower once estate agent fees, legal fees, removals and any early repayment charges are included.

Work out your next budget

Once you know your estimated equity, you can start to work out your next purchase budget.

This should include your likely deposit, the mortgage amount you may need, moving costs and a sensible cash buffer after completion. Your maximum borrowing figure is not always the same as the amount you should comfortably spend, especially if your monthly payments will increase.

Get an Agreement in Principle

An Agreement in Principle can give you an early indication of what you may be able to borrow. This can be useful before viewing properties seriously or making an offer.

It is not a guaranteed mortgage offer, but it can help you understand your budget and show estate agents that you have started checking your mortgage position.

Apply for your mortgage after your offer is accepted

Once your offer is accepted, you can usually move from an Agreement in Principle to a full mortgage application.

The lender will review your income, deposit, credit profile, commitments, current mortgage position and the property you want to buy. They will also arrange a valuation to check whether the property is suitable security for the loan.

Complete the legal and mortgage checks

Your solicitor or conveyancer will handle the legal side of the purchase. This includes reviewing the contract pack, checking the title, raising enquiries and completing searches.

At the same time, your lender will continue assessing the mortgage application. Once the lender is satisfied, they will issue a formal mortgage offer.

Exchange and complete

Exchange is the point where the purchase becomes legally binding. At this stage, the completion date is agreed and you usually pay your exchange deposit.

Completion is the day the mortgage funds are released, the purchase completes and you receive the keys. If you are selling and buying at the same time, your sale and purchase usually need to complete on the same day.

In simple terms

A moving home mortgage usually follows this path:

• check your current mortgage
• estimate your equity
• work out your next budget
• get an Agreement in Principle
• find your next property
• submit your full application
• complete valuation and legal checks
• receive your mortgage offer
• exchange contracts
• complete and move

The more you understand each step, the easier it becomes to plan your move around your mortgage, chain, costs and timing.

Your main mortgage options when moving home

When you move home, you do not always need to choose the same type of mortgage route you used before. Your next mortgage could involve keeping your current deal, switching to a new lender, borrowing more, reducing your borrowing or using a short-term solution if the timing of your sale and purchase does not line up.

The right option depends on your current mortgage, your equity, your new property price, your income and whether your existing lender can support your plans.

Port your current mortgage

Porting means taking your existing mortgage product with you to your new property. This can be useful if your current rate is lower than the deals available now, or if you want to avoid an early repayment charge.

However, porting is not automatic. Your lender will still need to check your income, affordability and the new property. If you need to borrow more, the extra amount may be placed on a separate mortgage product with its own rate, term and end date.

Porting can work well, but it should still be compared against switching to a new deal. Sometimes the rate you keep is attractive, but the overall structure may not be the best fit once fees, extra borrowing and product end dates are considered.

Switch to a new mortgage deal

You may choose to repay your existing mortgage when your home sells and arrange a new mortgage for your next property. This could be with your current lender or a different lender.

Switching may make sense if your current deal has ended, your early repayment charge is low, your current lender cannot offer enough borrowing or another lender has a more suitable option.

When comparing deals, it is important to look beyond the headline interest rate. Fees, incentives, mortgage term, loan-to-value, flexibility and early repayment charges can all affect the true cost of the mortgage.

Borrow more for your next home

If your next property is more expensive, you may need to borrow more. This is common when moving to a larger home, a different area or a property that better suits your long-term plans.

Lenders will reassess your income, spending, credit commitments and deposit. They will also look at the loan-to-value, which is the mortgage amount compared with the property value.

Borrowing more can increase your monthly payments and the total amount of interest you pay over time. Therefore, it is worth checking not only what you can borrow, but also what feels comfortable alongside your wider costs.

Reduce your borrowing when downsizing

If you are moving to a cheaper property, you may be able to reduce your mortgage balance or pay it off completely. This can lower your monthly payments, reduce long-term interest and free up money from your current home.

However, downsizing still needs careful planning. You may have early repayment charges, legal fees, estate agent fees, removals and stamp duty to consider. You may also want to keep a cash buffer for repairs, furniture or future plans.

For some movers, downsizing is less about buying the cheapest property and more about finding a better balance between mortgage payments, lifestyle and long-term financial flexibility.

Buy before you sell

In some cases, you may want or need to buy your next home before your current property sells. This can happen if you find the right property quickly, need to move for work, want to avoid losing a home or are dealing with a slow chain.

This route can involve more risk because you may temporarily own two properties. Options such as bridging finance or let-to-buy may be available in some circumstances, but they can be more complex and may cost more than a standard mortgage route.

Before choosing this option, it is important to understand the costs, risks, exit plan, and what happens if your current home takes longer to sell than expected.

Compare the route, not just the rate

The best moving home mortgage route is not always the one with the lowest rate on paper. A suitable option should also fit your timing, property chain, deposit, affordability, fees and future plans.

Muttuo Mortgages can help you compare whether porting, switching, borrowing more or restructuring your mortgage may suit your next move.

Mortgage types to consider when moving home

Once you know your main route, such as porting, switching or borrowing more, the next decision is the type of mortgage you choose for your new home.

Your mortgage type can affect how predictable your payments are, how much flexibility you have and how your costs may change after you move. This is especially important if your new mortgage is larger, your household costs are changing, or you want more certainty while settling into the new property.

Fixed-rate mortgages

A fixed-rate mortgage keeps your interest rate the same for a set period, such as two, three or five years. This means your monthly mortgage payments stay the same during the fixed period, unless you make changes to the mortgage.

This can be useful when moving home because your wider costs may already be changing. You may have a larger mortgage, higher bills, new commuting costs, renovation plans or family changes to think about. A fixed rate can make budgeting easier because you know what your mortgage payment will be each month.

However, fixed-rate deals often come with early repayment charges during the fixed period. If you think you may move again, overpay heavily or change your mortgage soon, you should check how flexible the deal is before committing.

Tracker mortgages

A tracker mortgage usually follows the Bank of England base rate, plus a set percentage. This means your payments can rise or fall if the base rate changes.

A tracker may appeal if you are comfortable with payment changes or want more flexibility than some fixed-rate deals offer. However, it can make budgeting less predictable, especially if you are already taking on a larger mortgage when moving home.

Before choosing a tracker, it is worth checking how much your payments could increase if rates rise. The monthly payment may look affordable at the start, but it needs to stay manageable if the rate moves.

Discount variable mortgages

A discount variable mortgage gives you a discount from the lender’s standard variable rate for a set period. Your payments can change if the lender changes its variable rate.

This type of mortgage can sometimes offer a lower starting rate, but it is less predictable than a fixed rate. The lender’s standard variable rate is not the same as the Bank of England base rate, although it may be influenced by wider market conditions.

If you are moving home and want certainty, this may not always be the most comfortable option. However, it may suit some borrowers who want a variable product and understand the risks.

Repayment mortgages

A repayment mortgage is the most common structure for residential buyers. Each monthly payment covers both interest and part of the mortgage balance.

Over time, your mortgage balance reduces, as long as you keep up with the payments. This can make repayment mortgages a straightforward option for movers who want to gradually pay down their borrowing.

If you are borrowing more for your next home, the mortgage term can make a big difference. A longer term may reduce the monthly payment, but it can increase the total interest paid over time.

Interest-only mortgages

With an interest-only mortgage, your monthly payments cover the interest only. The original mortgage balance does not reduce during the term, so you need a credible repayment plan to repay the loan at the end.

This can reduce monthly payments compared with a repayment mortgage, but it carries more risk. Lenders usually have stricter rules around interest-only borrowing, including income, equity, loan-to-value and acceptable repayment strategies.

For movers, interest-only may be considered in specific circumstances, but it should be reviewed carefully. Lower monthly payments do not mean the mortgage is cheaper overall.

Offset mortgages

An offset mortgage links your mortgage to savings held with the lender. Instead of earning interest on those savings, the balance is used to reduce the mortgage amount you are charged interest on.

This can be useful if you have savings after selling your home, receiving a bonus or keeping money aside for future plans. It may also appeal if you want to reduce interest while keeping access to your savings.

However, offset mortgages are not always the cheapest option by rate alone. The benefit depends on your savings balance, mortgage size, tax position and how long you keep money in the linked account.

Flexible mortgages

Some mortgages allow features such as overpayments, payment holidays or borrowing back previous overpayments, subject to lender rules.

Flexibility can be helpful after moving because your finances may change. You may want to overpay once moving costs settle, or you may want the option to reduce the mortgage faster if your income increases.

However, flexible features vary widely between lenders. It is important to check the actual terms, not just the product name.

Green mortgages

Some lenders offer green mortgage products for properties with higher energy efficiency ratings. These may be linked to the property’s Energy Performance Certificate rating.

This can be relevant if you are moving to a newer, more energy-efficient home or improving the property after purchase. However, green mortgage deals are not automatically the best option, so they should still be compared against standard products.

Choosing the right mortgage type

The right mortgage type depends on what matters most after you move. Some borrowers want certainty, some want flexibility and others want to reduce the total cost over time.

Before choosing, consider:

• how long you expect to stay in the property
• whether your mortgage balance is increasing
• how much payment certainty you need
• whether you may want to overpay
• whether you could handle higher payments if rates rise
• how product fees affect the overall cost
• whether early repayment charges could limit your options

A moving home mortgage should be chosen around the whole picture, not just the lowest rate. The rate matters, but so do the term, fees, flexibility, repayment method and how the mortgage fits your next stage of life.

How your property chain can affect your mortgage

A property chain is one of the biggest differences between moving home and buying as a first-time buyer. Instead of only arranging your purchase, you may also need your sale, your buyer, your seller and several other transactions to move forward at the same time.

This can affect your mortgage because your completion date often depends on more than lender approval. Even if your mortgage offer is ready, you may still need the rest of the chain to complete legal checks, agree dates and resolve any issues before you can move.

What is a property chain?

A property chain is created when several linked property transactions depend on each other.

For example, you may be selling your current home to a buyer who is also selling their property. At the same time, the person selling your next home may also be buying somewhere else. Each sale and purchase becomes connected.

If one person in the chain is delayed, it can affect everyone else. This is why moving home can sometimes take longer than expected, even when your own mortgage application is progressing well.

Why chains can delay your move

A chain can slow down if documents are missing, searches take longer than expected, survey issues appear or one buyer has problems with their mortgage application.

Delays can also happen if someone wants a different completion date, needs more time to arrange removals or is waiting for their own purchase to be ready.

This can be frustrating, but it is common. Your mortgage, solicitor and estate agent may all be ready at different times, so communication becomes important.

How your mortgage offer fits into the chain

Your mortgage offer confirms that the lender is prepared to provide the mortgage, subject to the offer terms and conditions. However, it does not mean you can complete immediately.

Your solicitor still needs to complete the legal work, your seller needs to be ready, and the rest of the chain needs to agree on a completion date.

If the chain takes too long, you may also need to watch your mortgage offer expiry date. Some lenders may allow an extension, but this depends on the lender, the product and your circumstances.

What happens if the chain breaks?

A chain can break if someone pulls out, cannot get a mortgage, receives a poor survey result, loses their buyer or changes their plans.

If this happens, your move may be delayed or, in some cases, fall through. You may need to wait for another buyer to be found, renegotiate the sale or review whether your mortgage offer is still suitable by the time the chain is ready again.

This is one reason why it helps to avoid making mortgage decisions in isolation. Your mortgage route should fit your wider move, including your sale, purchase, chain position and timing.

Can you move without a chain?

Some movers are chain-free. This may happen if they have already sold their property, are buying an empty property or are purchasing from someone who is not buying another home.

Being chain-free can sometimes make the process simpler because there are fewer linked transactions. However, your mortgage application, valuation, survey and legal checks still need to be completed.

In some cases, buyers consider options such as bridging finance or let-to-buy if they want to buy before selling. These routes can be more complex and may involve higher costs, so advice is important before committing.

What to check if you are in a chain

Before you move too far into the process, it helps to understand:

• how many people are in the chain
• whether your buyer has a mortgage agreed in principle
• whether your seller has found a property
• whether any property in the chain is leasehold or new build
• whether anyone has a tight deadline
• when your mortgage offer expires
• how quickly your solicitor can progress the legal work

The smoother the chain, the easier it can be to plan exchange and completion. However, even a simple chain can change, so it is worth building some flexibility into your moving timeline.

Selling and buying at the same time

Many home movers sell their current property and buy their next one at the same time. This is common, but it can make the process feel more connected because your sale, purchase, deposit, mortgage funds and completion date all need to line up.

In simple terms, the money from your sale usually helps repay your current mortgage and release the equity you need for your next purchase. Your new mortgage then helps fund the property you are buying.

Because both sides depend on each other, planning early can make the move feel much clearer.

How the money usually moves

On completion day, your buyer’s solicitor sends the purchase money to your solicitor. Your solicitor uses those funds to repay your existing mortgage and settle any sale-related costs.

The remaining equity can then be used towards your onward purchase. If you are also taking a new mortgage, your new lender releases the mortgage funds to your solicitor so they can complete the purchase of your next home.

This all usually happens on the same day if you are selling and buying together.

Why your equity matters

Your equity is a key part of the move because it may become the deposit for your next home.

For example, if your current home sells for £350,000 and your outstanding mortgage is £220,000, your estimated equity is £130,000 before selling and moving costs. Some of that money may then be used as your deposit on the next property.

However, your usable equity may be lower once estate agent fees, legal fees, removals, early repayment charges and other costs are included.

Why timing matters

Selling and buying together means your completion date needs to work for more than one person. Your buyer needs to be ready, your seller needs to be ready, your solicitor needs to complete the legal work, and your mortgage offer needs to be in place.

This is why a delay in one part of the chain can affect the whole move. Even if your mortgage is ready, completion cannot usually happen until the legal work and chain are ready too.

What happens if your sale is delayed?

If your sale is delayed, your onward purchase may also be delayed. This can affect your moving date, mortgage offer timeline and wider plans.

In some cases, a delay may mean your mortgage offer needs to be extended. In others, you may need to renegotiate dates with the seller or wait for your buyer to become ready.

If the delay is serious, you may need to review your mortgage options again, especially if rates have changed or your offer is close to expiring.

What happens if your purchase is delayed?

If the property you are buying is delayed, you may still be ready to sell but unable to complete your onward purchase.

Some movers choose to wait until both sides are ready. Others may consider temporary accommodation, storage or alternative finance options if they need to complete their sale before buying.

However, completing your sale before your purchase can create practical and financial questions, so it is worth taking advice before making that decision.

Can you buy before you sell?

Buying before you sell may be possible, but it is usually more complex.

You may need enough income and deposit to support the new mortgage without relying on the sale proceeds. You may also need to consider higher upfront costs, temporary ownership of two properties and whether additional stamp duty could apply.

Some buyers explore bridging finance or let-to-buy, but these options can carry higher costs and risks. They should be considered carefully and only when there is a clear plan for repaying or refinancing the borrowing.

What to check before selling and buying together

Before you commit to a move, it helps to check:

• how much your current home may sell for
• how much you still owe on your mortgage
• whether early repayment charges apply
• how much equity may be available after costs
• whether you can port your current mortgage
• how much you may be able to borrow
• whether your buyer and seller are ready to move
• how long your mortgage offer will last

Selling and buying at the same time is manageable, but it needs coordination. Muttuo Mortgages can help you understand how your mortgage, deposit, equity and timing fit together before you make your next move.

How your equity affects your next move

Your equity is one of the most important figures to understand when moving home. It can shape your deposit, loan-to-value, next mortgage amount, and overall moving budget.

In simple terms, equity is the difference between what your current home is worth and how much you still owe on your mortgage. However, the amount you can actually use towards your next move may be lower once selling costs, mortgage charges and moving expenses are taken into account.

How to work out your equity

You can estimate your equity by subtracting your outstanding mortgage balance from your current property value.

For example:

• Estimated property value: £350,000
• Outstanding mortgage balance: £220,000
• Estimated equity: £130,000

This gives you a useful starting point. However, it is only an estimate until your home sells and your mortgage balance is confirmed at completion.

Why usable equity may be lower

Your estimated equity is not always the same as the amount available for your next deposit.

Before deciding how much you can put towards your next home, you may need to allow for:

• estate agent fees
• solicitor or conveyancer fees
• removal costs
• survey costs
• mortgage arrangement fees
• early repayment charges
• money kept aside for repairs, furniture or emergencies

For example, if your estimated equity is £130,000 and your moving costs are around £15,000, you may have closer to £115,000 available for your next deposit and related costs.

How equity affects your deposit

The more equity you have, the more deposit you may be able to put towards your next property. This can reduce the amount you need to borrow and may improve your loan-to-value.

However, it is worth being careful about using every pound of equity as your deposit. Moving home can bring unexpected costs, especially if the new property needs work or your completion timeline changes.

Keeping a cash buffer can make the move feel more manageable after completion.

How equity affects loan-to-value

Loan-to-value, often called LTV, is the mortgage amount compared with the property value.

For example, if you buy a property for £400,000 and need a mortgage of £300,000, your loan-to-value is 75%.

Your LTV can affect the mortgage deals available to you. In many cases, a lower LTV can give you access to more options, although lenders will also consider your income, affordability, credit profile and property type.

Moving to a more expensive home

If your next home costs more than your current one, your equity may not stretch as far as expected.

For example, you may have built up a good amount of equity, but if the new property is significantly more expensive, you may still need to borrow more. This can increase your monthly payments and total mortgage cost.

This is why it helps to look at your equity and affordability together. Your equity may support the move, but the lender still needs to check whether the new mortgage is affordable.

Moving to a cheaper home

If you are downsizing, your equity may allow you to reduce your mortgage balance, lower your monthly payments or release money from your current property.

This can be useful if you want more financial flexibility, fewer monthly commitments or a smaller mortgage later in life.

However, downsizing still comes with costs. You should still check early repayment charges, moving costs, stamp duty where applicable and how much money you want to keep available after the move.

Why equity should not be viewed in isolation

Equity is important, but it is only one part of your moving home mortgage decision.

Before making an offer, it is worth looking at:

• your estimated sale price
• your outstanding mortgage balance
• your usable equity after costs
• your next property price
• the mortgage amount needed
• your loan-to-value
• your monthly payment
• your cash buffer after completion

Your equity can help you move, but the best mortgage route depends on how your deposit, borrowing, costs and timing fit together.

How much can you borrow when moving home?

How much you can borrow when moving home depends on more than your current property value or deposit. Lenders will look at your income, spending, credit profile, commitments, mortgage term and the property you want to buy.

Your equity can help reduce the amount you need to borrow, but it does not replace affordability checks. Even if you have a large deposit, the lender still needs to be comfortable that the new mortgage is affordable now and in the future.

What lenders usually assess

When you apply for a moving home mortgage, lenders usually review your overall financial position.

This can include:

• your basic income
• bonus, commission or overtime
• self-employed income
• credit commitments
• childcare costs
• household spending
• existing mortgage payments
• deposit size
• loan-to-value
• credit history
• mortgage term
• age and retirement plans
• the type and condition of the property

Different lenders assess these details in different ways. One lender may be comfortable with your situation, while another may offer less borrowing or decline the application.

Why your next budget is not just your maximum borrowing

Your maximum borrowing figure is not always the same as the amount you should spend.

For example, a lender may be willing to offer a certain mortgage amount, but the monthly payment still needs to feel manageable alongside your wider costs. When moving home, those costs may include higher bills, council tax, commuting, repairs, furnishing and the cost of settling into a new property.

This is why it helps to think in two ways:

• what a lender may allow you to borrow
• what you would feel comfortable paying each month

A good moving home budget should consider both.

How your deposit affects borrowing

Your deposit can affect the mortgage deals available to you because it influences your loan-to-value.

A larger deposit usually means you need to borrow less compared with the property value. This may help you access a wider range of mortgage options, although the exact products available will depend on the lender and your wider circumstances.

However, using all your available cash as a deposit is not always the best approach. You may need money left over for stamp duty, legal fees, removals, repairs, furniture and emergencies after completion.

Borrowing more for a bigger property

If you are moving to a more expensive home, you may need a larger mortgage. This is common when moving to a bigger property, a better location or a home that better suits your long-term plans.

However, borrowing more can affect:

• your monthly payment
• your loan-to-value
• the mortgage rate available
• your affordability assessment
• the total interest paid over the mortgage term
• how much flexibility you have after moving

Before increasing your borrowing, it is worth checking how the new mortgage would feel in real life, not just whether it is possible on paper.

How income changes can affect your options

Your income may have changed since you arranged your current mortgage. You may have a higher salary, a new job, different working hours, self-employed income, bonus income or a change in household earnings.

Lenders may also look at how stable your income is. For example, if you have recently changed jobs, started a business or moved from employed to self-employed work, some lenders may want more evidence before they are comfortable lending.

If your income is variable, the lender may use an average or only count part of it. This can affect how much you can borrow.

How debts and commitments affect affordability

Existing debts and regular commitments can reduce how much you may be able to borrow.

This can include:

• personal loans
• credit cards
• car finance
• childcare costs
• maintenance payments
• student loans
• existing mortgage commitments
• other regular financial obligations

Even if you manage these payments comfortably, lenders may still include them in the affordability calculation. Reducing certain commitments before applying may help in some cases, but it depends on the lender and your wider situation.

Why lender choice matters

Moving home is not always straightforward. You may be porting, borrowing more, using equity from a sale, working around a chain or applying with income that has changed since your last mortgage.

Because lenders use different affordability models, the amount you can borrow can vary from one lender to another. Some lenders may be stronger for employed applicants, while others may be more flexible with self-employed income, bonus income, contractors or complex circumstances.

Muttuo Mortgages can help you compare options across different lenders, so you can get a clearer view of what may be possible before making an offer.

Before you make an offer

Before committing to a property, it helps to check:

• how much equity you may have
• how much deposit you can realistically use
• what you may be able to borrow
• what the monthly payment could look like
• whether the mortgage feels comfortable alongside other costs
• whether your Agreement in Principle is still up to date
• whether your current mortgage has early repayment charges

The aim is not just to find the highest mortgage available. It is to find a mortgage that supports your move without stretching your finances too far.

What costs should you plan for when moving home?

Moving home can involve more than your deposit and monthly mortgage payment. There are upfront costs, selling costs, mortgage-related charges and practical moving expenses to plan for.

Some costs are easy to predict, such as estate agent fees or removals. Others can depend on your property price, mortgage deal, location, survey results or whether you have an early repayment charge on your current mortgage.

Stamp duty

Stamp duty can be one of the largest upfront costs when buying your next home. The amount you pay depends on the purchase price, where the property is located and whether you already own another property at the point of completion.

If you are selling your current main residence and buying another main residence, you may not need to pay the higher additional property surcharge. However, if you buy before you sell, the rules can become more complicated.

Because stamp duty can affect how much cash you have available, it should be checked before you make an offer.

Estate agent fees

If you are selling your current home, you may need to pay estate agent fees. These are usually charged as a percentage of the sale price, although some agents may offer fixed-fee options.

This cost is usually paid from the sale proceeds, but it still reduces the amount of equity available for your next purchase.

Solicitor or conveyancer fees

You will usually need legal support for both your sale and purchase. Your solicitor or conveyancer will handle the contract, title checks, searches, enquiries, mortgage requirements and transfer of funds.

Legal fees can vary depending on the property, whether it is freehold or leasehold, whether there is a chain and how complex the transaction becomes.

Survey and valuation costs

Your lender will usually arrange a mortgage valuation to check whether the property is suitable security for the loan. This is not the same as a detailed survey.

You may also choose to arrange your own property survey. This can help identify issues such as damp, roof problems, structural movement or repair work that may be needed.

A survey can add to your upfront costs, but it may help you avoid larger surprises after completion.

Mortgage fees

Some mortgage products come with arrangement fees, booking fees or valuation fees. In some cases, you may be able to add certain fees to the mortgage, but this can mean paying interest on them over time.

You should compare the total cost of the deal, not just the interest rate. A mortgage with a lower rate and a high fee may not always be cheaper than a deal with a slightly higher rate and lower upfront costs.

Early repayment charges

If you leave your current mortgage deal before the product period ends, you may need to pay an early repayment charge.

This can matter if you are switching lender, repaying your current mortgage or deciding whether to port your existing deal. Before you commit to a move, check your product end date and any charges that may apply.

Removal and storage costs

Moving your belongings can also add to the cost of moving home. Removal costs may vary depending on the distance, property size, amount of furniture and whether you need packing support.

Storage may also be needed if there is a gap between selling your current home and moving into your next one.

Repairs, furniture and setup costs

Once you move in, you may need money for decorating, repairs, new furniture, appliances, utilities, insurance and general setup costs.

These costs are easy to underestimate because they often come after the main purchase has completed. Keeping some money aside can help you avoid using all your available cash on the deposit alone.

Why a cash buffer matters

A moving budget should include more than the minimum amount needed to complete.

Before deciding how much deposit to use, it is worth allowing for:

• stamp duty
• legal fees
• estate agent fees
• mortgage fees
• surveys
• removals
• early repayment charges
• storage
• repairs and furniture
• money left over after completion

The aim is to move with a clear budget, not just enough money to complete the purchase. This can make your next home feel more manageable from day one.

Moving home when your current mortgage deal has not ended

You can move home before your current mortgage deal ends, but you need to understand what happens to your existing product. This is especially important if you are on a fixed, tracker or discount deal with early repayment charges.

In some cases, you may be able to port your mortgage and keep your current rate. In other cases, you may decide to switch to a new deal, pay an early repayment charge or time your move around your product end date.

The right option depends on your current rate, the size of any charge, the new mortgage you need and the deals available when you move.

Check your product end date first

Your product end date is the date your current fixed, tracker or discounted period ends. After that, your mortgage may move onto your lender’s standard variable rate unless you arrange a new deal.

If your product end date is close, you may have more flexibility when moving. If it is still months or years away, you may need to think more carefully about early repayment charges and whether porting is possible.

Before making an offer, check:

• when your current deal ends
• what rate you are currently paying
• whether your mortgage is portable
• whether early repayment charges apply
• whether any exit or administration fees apply

These details can affect whether it makes sense to stay with your current lender or compare new options.

What early repayment charges mean

An early repayment charge is a fee you may need to pay if you repay your mortgage, switch lender or leave your deal before the product period ends.

The charge is often calculated as a percentage of the amount being repaid. For example, if your charge is 2% and your remaining mortgage balance is £200,000, the early repayment charge could be £4,000.

This can be a significant cost, so it should be included in your moving budget from the start.

Porting may help you avoid a charge

If your mortgage is portable, you may be able to take your current product to your new home. This can sometimes help you avoid or reduce an early repayment charge.

However, porting is not guaranteed. Your lender will still need to check your income, affordability, credit profile and the property you want to buy. If you need to borrow more, the extra borrowing may be placed on a separate deal with a different rate and product end date.

This means porting can help, but it still needs to be compared carefully against switching.

Paying the charge may still make sense

In some cases, paying an early repayment charge and moving to a new mortgage may still be worth considering.

This could happen if another lender offers a more suitable option, if your current lender cannot support the borrowing you need, or if the long-term cost of staying with your current deal is higher than switching.

However, this decision should be based on the full cost, not just the interest rate.

You need to compare:

• the early repayment charge
• any new mortgage fees
• the new interest rate
• monthly payments
• total cost over the deal period
• flexibility and future plans

A lower rate does not always mean a cheaper mortgage once fees and charges are included.

Timing your move around your deal end date

If your current deal is close to ending, it may be worth thinking about whether your sale and purchase can be timed around that date.

This could reduce or avoid early repayment charges. However, moving home depends on several factors, including your buyer, seller, solicitor, lender and wider property chain.

It is not always possible to control the timing exactly, so it helps to understand your options early rather than waiting until you have already agreed dates.

What happens if your move completes after your deal ends?

If your current mortgage deal ends before you move, your mortgage may move onto your lender’s standard variable rate. This could increase your monthly payments, depending on the rate.

At that point, you may need to decide whether to stay temporarily on the standard variable rate, arrange a new product with your current lender or continue with your moving plans.

Before choosing a new deal, check whether it could create fresh early repayment charges that make your move more expensive.

Before you decide what to do

If your current mortgage deal has not ended, it helps to check your position before viewing seriously or making an offer.

You should understand:

• whether your mortgage is portable
• how much any early repayment charge could be
• whether you need to borrow more
• whether your current lender can support the move
• how your current rate compares with new deals
• when your current product ends
• how your property chain could affect timing

Moving before your mortgage deal ends can still work, but the numbers need to be clear. The best route is the one that fits your rate, charges, borrowing needs, timing and overall cost.

Mortgage offer expiry and delays when moving home

A mortgage offer does not usually stay valid forever. When you are moving home, this matters because your purchase may depend on your property chain, legal work, survey results and completion date.

Even if your mortgage offer is approved, you still need the rest of the move to line up before completion can happen. If the process takes longer than expected, you may need to extend your mortgage offer, update your details or, in some cases, apply again.

How long does a mortgage offer last?

Mortgage offer lengths vary by lender and product. Many offers are valid for several months, but the exact period should always be checked on your offer document.

The offer will usually confirm the property, loan amount, interest rate, mortgage term, monthly payment, fees and any conditions that need to be met before completion.

If you are in a short chain and the legal work moves quickly, the offer may last long enough without any issue. If the chain is long, the property is leasehold or you are buying a new build, timing can become more important.

Why mortgage offers can expire

A mortgage offer can expire if the purchase does not complete before the offer end date.

This may happen because of:

• property chain delays
• slow legal enquiries
• search delays
• survey issues
• leasehold management pack delays
• new-build completion delays
• changes in the buyer’s or seller’s circumstances
• renegotiations after a valuation or survey
• delays agreeing an exchange or completion date

When you are moving home, the delay may not be caused by your own mortgage application. It can come from another part of the chain.

What happens if your offer is close to expiring?

If your mortgage offer is close to expiring, you should speak to your broker, lender and solicitor as early as possible.

Some lenders may allow an extension, especially if the purchase is close to completion. Others may ask for updated documents, a new credit check, a refreshed valuation or a new affordability assessment.

Whether an extension is possible depends on the lender, the mortgage product, the property and your circumstances at the time.

What happens if your offer expires?

If your mortgage offer expires before completion, you may need to reapply or choose a new deal.

This can create a few risks. Rates may have changed, lender criteria may be different and your affordability may be reassessed. If your income, spending, credit profile or employment has changed since the original application, the new assessment could produce a different outcome.

This is why it helps to keep your broker updated if anything changes during the moving process.

Changes that can affect your mortgage offer

After your mortgage offer is issued, you should avoid making major financial changes without advice.

Changes that could affect the offer include:

• changing jobs
• reducing your working hours
• taking on new credit
• increasing credit card balances
• missing payments
• changing your deposit source
• renegotiating the purchase price
• changing the property you are buying
• significant changes to your income or commitments

Some changes may be manageable, but they still need to be reviewed. It is better to check early than risk a problem near exchange or completion.

Why new builds need extra care

Mortgage offer expiry can be especially important with new-build homes because the completion date may depend on the build schedule.

If the property is delayed, your mortgage offer may need to be extended. Some lenders have specific new-build offer rules, while others may require a fresh application if the delay is too long.

If you are buying a new build, make sure you understand the developer’s expected completion date, long-stop date and how long your mortgage offer is valid for.

How to reduce the risk of delays

You cannot control every part of a move, but you can reduce avoidable delays by preparing early.

It helps to:

• provide documents quickly
• respond to solicitor enquiries promptly
• check your mortgage offer expiry date
• keep your broker updated on any changes
• ask your solicitor for progress updates
• understand your chain position
• avoid new borrowing before completion
• raise any concerns before exchange

The smoother your paperwork and communication, the easier it is to keep the mortgage side of the move on track.

The key point

Your mortgage offer is an important step, but it is not the final stage of moving home. Completion still depends on your legal work, property chain, seller, solicitor, lender and agreed moving date.

Keeping an eye on your offer expiry date can help you avoid last-minute pressure and make sure your mortgage is still ready when the rest of your move is ready too.

Moving home with a new-build or leasehold property

Some property types can add extra steps to your moving home mortgage. New-build homes and leasehold properties are two common examples because lenders and solicitors may need to check more details before completion.

This does not mean they are unsuitable. It simply means the mortgage, legal work and timing may need closer attention.

Moving home to a new-build property

A new-build purchase can work slightly differently from buying an existing home. You may need to reserve the property early, exchange contracts within a set timeframe and wait for the home to be finished before completion.

This can affect your mortgage because your offer needs to stay valid until the property is ready. If the build is delayed, you may need a mortgage offer extension or, in some cases, a new application.

You should also check whether the lender is comfortable with the property, the deposit, any developer incentives and the expected completion timeline.

Developer incentives and your mortgage

Some new-build homes come with incentives, such as contributions towards legal fees, stamp duty, upgrades or cashback.

These can be helpful, but they need to be declared to the lender. The lender may take them into account when valuing the property or assessing the mortgage.

Before relying on an incentive, it is worth checking whether it affects your mortgage options or the amount the lender is willing to offer.

Mortgage offer expiry on new builds

New-build completion dates can move. This makes mortgage offer expiry especially important.

Before you commit, check:

• when the property is expected to complete
• whether there is a long-stop date
• how long your mortgage offer will last
• whether the lender allows extensions
• what happens if the build is delayed

This can help you avoid pressure later if the property is not ready when expected.

Moving home to a leasehold property

A leasehold property can involve additional legal checks. Your solicitor will usually review the lease, service charges, ground rent, management information and any restrictions that apply to the property.

Lenders may also have rules around lease length, ground rent terms, service charges and the overall suitability of the property.

Because of this, leasehold purchases can sometimes take longer than freehold purchases, especially if the management pack is delayed or the solicitor needs to raise extra enquiries.

What your solicitor may need to check

For a leasehold property, your solicitor may review:

• how many years are left on the lease
• ground rent terms
• service charge levels
• building insurance arrangements
• maintenance responsibilities
• planned major works
• management company information
• restrictions on alterations or letting
• building safety information, where relevant

These checks help confirm whether the property can be legally transferred and whether it meets the lender’s requirements.

Why property type can affect timing

The type of property you buy can affect how quickly your mortgage and legal work progress.

A straightforward freehold house may move through the process faster than a leasehold flat, a new-build property or a home with unusual construction. However, every case is different.

The important thing is to understand any extra checks early, so you can plan your timeline and avoid surprises close to exchange or completion.

What to check before making an offer

Before making an offer on a new-build or leasehold home, it helps to check:

• whether the property is freehold or leasehold
• whether the lender is likely to accept the property type
• how long the lease has left, if leasehold
• whether service charges or ground rent could affect affordability
• whether there are developer incentives
• whether the expected completion date fits your mortgage offer
• whether your current sale and chain can match the timeline

New-build and leasehold homes can still be strong options when moving home. The key is making sure your mortgage, legal checks and completion timing all work together.

Moving home mortgage timeline

The moving home mortgage timeline can vary depending on your property chain, lender, solicitor, survey results and how quickly documents are provided. However, most movers follow a similar journey from checking their current position through to completion day.

Some stages happen one after another, while others overlap. For example, your mortgage application, valuation, property survey and legal work may all move forward at the same time.

01 Check your current mortgage and equity

Estimated time: Instant to a few days

Start by checking your outstanding mortgage balance, current rate, product end date and any early repayment charges. You should also estimate how much equity you may have in your current home.

This gives you a clearer starting point before you work out your next budget.

02 Estimate what you could borrow

Estimated time: Instant to a few days

Once you understand your equity, you can estimate how much you may be able to borrow for your next property.

This should include your income, deposit, commitments, loan-to-value, credit profile and wider moving costs. Your maximum borrowing figure should also be compared against what feels comfortable each month.

03 Get an Agreement in Principle

Estimated time: Around 1 week

An Agreement in Principle can help you understand what you may be able to borrow before you make an offer.

It can also show estate agents and sellers that you have started checking your mortgage position. However, it is not a guaranteed mortgage offer.

04 Find your next property

Estimated time: Often 12 to 24 weeks

Finding the right property can be one of the longest parts of the moving process. Your search may depend on your budget, location, chain position and how quickly your current home sells.

If your Agreement in Principle expires during your search, you may need to refresh it.

05 Submit your full mortgage application

Estimated time: A few days to 1 week to prepare and submit

Once your offer is accepted, you can usually move from an Agreement in Principle to a full mortgage application.

The lender will review your income, deposit, financial commitments, credit profile and the property you want to buy. You may also need to provide documents such as payslips, bank statements, ID and proof of deposit.

06 Arrange the valuation and survey

Estimated time: Around 1 to 2 weeks

The lender will usually arrange a mortgage valuation to check whether the property is suitable security for the loan.

You may also choose to arrange your own survey. This can give you more detail about the property’s condition and highlight possible repair issues before you commit.

07 Receive your mortgage offer

Estimated time: Often 1 to 2 weeks after lender checks are complete

If the lender is satisfied with your application and the property valuation, they will issue a formal mortgage offer.

Your offer will confirm the loan amount, rate, mortgage term, monthly payments, fees and any conditions that need to be met before completion.

08 Complete legal checks and searches

Estimated time: Often 6 to 12 weeks

Your solicitor or conveyancer will review the contract pack, raise enquiries, check the title and complete searches.

This stage can overlap with the mortgage process. Even if your mortgage offer is ready, you may still need to wait for legal checks, search results and the wider chain before exchange can happen.

09 Exchange contracts

Estimated time: Once the mortgage and legal work are complete

Exchange is the point where the purchase becomes legally binding. Your completion date is agreed, and you usually pay your exchange deposit.

Before exchange, your solicitor will usually confirm that the mortgage offer is in place, the legal work is complete and the agreed completion date works for the chain.

10 Complete and move

Estimated time: Usually same day to 2 weeks after exchange

Completion is the day the mortgage funds are released, the purchase completes and you receive the keys.

If you are selling and buying at the same time, your sale and purchase usually need to complete on the same day. Your solicitor will coordinate the mortgage funds, sale proceeds and purchase funds so the move can complete.

Stage	Typical timing
Check your current mortgage and equity	Instant to a few days
Estimate what you could borrow	Instant to a few days
Get an Agreement in Principle	Around 1 week
Find your next property	Often 12 to 24 weeks
Submit your mortgage application	A few days to 1 week to prepare and submit
Arrange the valuation and survey	Around 1 to 2 weeks
Receive your mortgage offer	Often 1 to 2 weeks after lender checks are complete
Complete legal checks and searches	Often 6 to 12 weeks
Exchange contracts	Once mortgage and legal work are complete
Complete and move	Usually same day to 2 weeks after exchange

The key point is that your mortgage timeline is connected to the wider move. Your lender, solicitor, estate agent, seller, buyer and property chain all play a part in how quickly you can exchange and complete.

Documents you may need for a moving home mortgage

When you apply for a moving home mortgage, the lender will need to check your identity, income, deposit, current mortgage position and the property you want to buy.

Having your documents ready can help keep the application moving. It can also reduce the chance of delays once your offer has been accepted and the lender begins the full assessment.

Proof of identity and address

Most lenders will need to confirm who you are and where you live. This usually means providing documents such as a passport, driving licence, utility bill, council tax bill or bank statement.

The exact documents accepted can vary by lender, so it is worth checking before you apply.

Proof of income

If you are employed, lenders may ask for recent payslips and sometimes your latest P60. If your income includes bonus, overtime or commission, they may ask for extra evidence to see how regular that income is.

If you are self-employed, the lender may request tax calculations, tax year overviews, accounts or business bank statements. Some lenders assess self-employed income differently, so the documents needed can vary.

Bank statements

Lenders often ask for recent bank statements to review your income, spending and regular commitments.

They may look at salary payments, bills, childcare costs, credit commitments, overdraft use and general account conduct. If there are large transfers or unusual payments, the lender may ask for more information.

Proof of deposit

When moving home, your deposit may come from the equity in your current property, savings, a gifted deposit or a combination of sources.

You may need to show where the money is coming from. This could include savings statements, evidence of sale proceeds, a gifted deposit letter or confirmation from your solicitor.

Current mortgage details

Because you are moving from an existing home, your lender or broker may need details of your current mortgage.

This can include:

• your outstanding mortgage balance
• your current interest rate
• your product end date
• any early repayment charges
• whether your mortgage is portable
• your latest mortgage statement

These details help show what will happen to your existing mortgage when you sell.

Property details

Once you have had an offer accepted, the lender will need details of the property you want to buy.

This may include the purchase price, property type, address, tenure, estate agent details and solicitor details. If the property is leasehold, new build or has unusual features, the lender may ask for more information.

Details of financial commitments

The lender will also ask about your existing financial commitments. These can affect affordability because they reduce the amount of income available for the new mortgage.

This may include:

• loans
• credit cards
• car finance
• student loans
• childcare costs
• maintenance payments
• other mortgages or property commitments

Being accurate here is important. The lender will usually check your credit file and bank statements as part of the application.

Documents for your sale and onward purchase

If you are selling and buying at the same time, your solicitor will also need documents linked to your current sale and next purchase.

This may include your sale memorandum, purchase memorandum, contract pack, property information forms and details of any existing mortgage being repaid.

Your solicitor and lender do different jobs, but delays in one part of the process can affect the whole move.

Get ready before your offer is accepted

You do not need every document before you start viewing properties, but it helps to prepare early.

Before you apply, it is useful to have:

• ID and proof of address
• recent payslips or income evidence
• recent bank statements
• proof of deposit
• current mortgage statement
• details of credit commitments
• solicitor details, if already chosen
• information about your sale and purchase

Having these ready can make the move from offer accepted to full mortgage application much smoother.

What can delay a moving home mortgage?

A moving home mortgage can be delayed for several reasons. Sometimes the delay comes from the mortgage application itself. Other times, it comes from the property, solicitor, seller, buyer or wider chain.

Not every delay can be avoided, but many can be reduced by preparing documents early, responding quickly and checking your mortgage position before making an offer.

Missing or unclear documents

Lenders need the right documents to assess your application. If payslips, bank statements, proof of deposit or ID are missing, the application can slow down.

Delays can also happen if documents are unclear, out of date or do not match the information on your application. For example, if your bank statements show regular payments that were not declared, the lender may ask extra questions before moving forward.

Income that needs extra checks

Some income types can take longer to assess. This can include self-employed income, bonuses, commission, overtime, contractor income, multiple jobs or income from a limited company.

This does not mean you cannot get a mortgage. It simply means the lender may need more evidence to understand how stable and reliable the income is.

Property chain delays

Your mortgage may be ready before the rest of the chain is ready. If another buyer, seller, solicitor or lender is delayed, exchange and completion may need to wait.

This is one of the most common reasons a moving home timeline changes. Your own mortgage application may be progressing well, but the overall move still depends on the linked transactions.

Valuation or survey issues

A lender’s valuation may raise concerns about the property. For example, the lender may value the property lower than the agreed purchase price, ask for specialist reports or add conditions to the mortgage offer.

A buyer’s survey may also uncover repair work, damp, roof issues or structural concerns. If this happens, you may need to renegotiate, ask further questions or decide whether the property still feels right.

Leasehold or new-build checks

Leasehold and new-build properties can involve extra checks.

For leasehold homes, the solicitor may need to review the lease, ground rent, service charges, management pack and building safety information. For new builds, the lender may need to consider the completion date, incentives and mortgage offer expiry.

These checks can add time, especially if information is slow to arrive.

Changes to your circumstances

If your circumstances change after you apply, the lender may need to reassess your application.

This could include:

• changing job
• reducing your hours
• taking on new credit
• increasing credit card balances
• missing payments
• changing your deposit source
• renegotiating the purchase price
• changing the property you want to buy

Some changes may be manageable, but they should be checked before exchange or completion.

Mortgage offer expiry

If the move takes longer than expected, your mortgage offer may get close to expiry. This can be more likely with long chains, leasehold homes or new-build purchases.

Some lenders may allow an extension, but others may need updated documents, a new affordability check or a fresh application. This can create pressure if you are already close to exchange.

Slow legal enquiries

Your solicitor may need to raise questions with the seller’s solicitor before you can exchange contracts. These enquiries can relate to boundaries, planning permissions, leasehold details, guarantees, fixtures and fittings or previous building work.

If answers are slow or incomplete, the legal process can take longer than expected.

How to reduce avoidable delays

You cannot control every part of the moving process, but you can reduce avoidable delays by preparing early.

It helps to:

• check your mortgage options before making an offer
• prepare your documents in advance
• respond quickly to lender and solicitor requests
• choose a solicitor early
• check your mortgage offer expiry date
• avoid new borrowing before completion
• keep your broker updated if anything changes
• understand your property chain position

Moving home often involves several people and stages, so some waiting is normal. However, the more prepared you are, the easier it is to keep your mortgage application and wider move on track.

Common moving home mortgage mistakes to avoid

Moving home can be busy, so it is easy to focus on the property and leave the mortgage details until later. However, small assumptions can create delays, extra costs or pressure later in the process.

These are some of the most common mistakes to avoid before you commit to your next move.

Starting your property search before checking your budget

It is tempting to start viewing homes before checking what you can borrow. However, your next budget depends on your equity, deposit, income, commitments, mortgage options and moving costs.

Checking your mortgage position early can help you focus on homes that fit your real budget, not just your preferred search area or asking price.

Assuming your current mortgage will move with you

Some mortgages are portable, but porting is not automatic. Your lender still needs to approve your new application and the property you want to buy.

If you need to borrow more, the extra amount may also sit on a different rate with a different product end date. This can make the overall structure more complex than expected.

Forgetting about early repayment charges

If your current mortgage deal has not ended, you may need to pay an early repayment charge if you repay it or switch lender.

This cost can affect whether it makes sense to port, switch or wait until your current deal is closer to ending. It should be checked before you accept an offer or commit to a purchase.

Underestimating moving costs

Your deposit is only one part of the cost of moving home. You may also need to pay stamp duty, estate agent fees, solicitor fees, survey costs, removals, mortgage fees and insurance.

If you use all your available money as a deposit, you may have less flexibility after completion. A cash buffer can help with repairs, furniture, setup costs and unexpected expenses.

Focusing only on the interest rate

A low rate can look attractive, but it does not tell the full story. Product fees, valuation fees, early repayment charges, mortgage term, flexibility and total cost all matter.

When moving home, you should compare the full mortgage structure, not just the headline rate.

Ignoring the property chain

Your mortgage may be approved before the rest of the chain is ready. Legal checks, searches, survey issues, buyer delays and seller delays can all affect your exchange and completion date.

Understanding your chain position early can help you plan your mortgage offer timing and avoid last-minute pressure.

Making changes before completion

Taking out new credit, changing jobs, reducing hours or increasing credit card balances before completion can affect your mortgage application.

Even after a mortgage offer has been issued, the lender may need to know about major changes. It is safer to check before making financial decisions during the moving process.

Not checking the mortgage offer expiry date

Mortgage offers are only valid for a set period. If your chain, legal work or new-build completion takes longer than expected, your offer may need to be extended.

Checking the expiry date early gives you more time to act if the move starts to run behind.

Using all your equity as your deposit

Equity can help fund your next purchase, but it may not all be available once selling costs and moving costs are included.

It is worth separating your estimated equity from your usable equity. This gives you a more realistic view of how much you can put towards your next home.

Waiting too long to get mortgage advice

A broker can often help before you have found a property. Early advice can help you understand whether porting, switching, borrowing more or reducing your mortgage may be suitable.

This can make your property search more focused and reduce the risk of finding a home before knowing whether the mortgage side works.

The key point

Most moving home mortgage mistakes come from making decisions too late or looking at one part of the move in isolation.

Before you commit, it helps to check your mortgage, equity, affordability, costs, chain position and timing together. That gives you a clearer view of what is realistic before you make your next move.

Moving home mortgage checklist

Moving home is easier to manage when you know what to check at each stage. Use this checklist as a simple guide before you start viewing, making offers and preparing your mortgage application.

Before you start viewing

• Check your current mortgage balance, rate and product end date.
• Find out whether your mortgage is portable.
• Check whether early repayment charges apply.
• Estimate your current home value and equity.
• Work out how much you may have available after selling and moving costs.

Before making an offer

• Get an Agreement in Principle.
• Check what you may be able to borrow.
• Compare porting, switching and borrowing more.
• Estimate your upfront costs, including stamp duty, legal fees and removals.
• Ask about the property chain and expected timescales.

After your offer is accepted

• Prepare your ID, income evidence, bank statements and proof of deposit.
• Submit your full mortgage application.
• Choose your solicitor or conveyancer.
• Arrange a survey if you want one.
• Respond quickly to lender and solicitor requests.

Before exchange and completion

• Review your mortgage offer carefully.
• Check your mortgage offer expiry date.
• Confirm your exchange deposit and completion date.

FAQs about moving home mortgages

Moving home can raise a lot of mortgage questions, especially if you are selling, buying, porting, borrowing more or working around a property chain.

These FAQs cover some of the most common questions movers ask before applying for a new mortgage or making an offer on their next home.

Can I move home with my current mortgage?

You may be able to take your current mortgage deal with you, but your lender still needs to approve the move.

You may be able to move home with your current mortgage if your mortgage is portable. This means you can apply to take your existing mortgage product to your new property.

However, porting is not automatic. Your lender will still reassess your income, affordability and the property you want to buy. If you need to borrow more, the extra borrowing may sit on a separate deal with a different rate and end date.

What happens to my mortgage when I sell my house?

Your existing mortgage is usually repaid from the sale proceeds when your current home completes.

When you sell your current home, your existing mortgage is usually repaid from the sale proceeds on completion day.

Your solicitor receives the money from your buyer, repays your outstanding mortgage balance and then uses any remaining equity towards your onward purchase. If you are porting, your current mortgage product may be moved to the new property, subject to lender approval.

Is porting my mortgage guaranteed?

No, porting is still subject to a new application and lender checks.

No. Even if your current mortgage is portable, your lender still needs to approve the new application.

They will usually check your income, spending, credit profile, loan-to-value and the property you are buying. If your circumstances have changed since your original application, this could affect whether porting is available.

Can I borrow more when moving home?

Yes, you may be able to borrow more if the lender is comfortable with your affordability.

Yes, you may be able to borrow more when moving home if the lender is comfortable with your affordability and the new property.

This may be needed if your next home costs more than your current property. The lender will usually assess your income, commitments, deposit, credit profile and loan-to-value before deciding how much they may be willing to lend.

Do I need an Agreement in Principle before making an offer?

You do not always need one, but it can help you understand your budget before you commit.

You do not always need one, but an Agreement in Principle can be helpful before making an offer.

It can give you an early idea of what you may be able to borrow and may show estate agents that you have started checking your mortgage position. However, it is not a guaranteed mortgage offer.

Can I move home before my fixed rate ends?

Yes, but you should check whether early repayment charges apply before making a decision.

Yes, but you need to check whether early repayment charges apply.

If your mortgage is portable, you may be able to take your current deal with you. If you switch lender or repay the mortgage early, a charge may apply. The right option depends on your current rate, the charge, your borrowing needs and the deals available when you move.

How does a property chain affect my mortgage?

Your mortgage may be ready before the rest of the chain is ready to complete.

A property chain can affect when you exchange and complete. Even if your mortgage offer is ready, your move may still depend on your buyer, seller, solicitor and other people in the chain.

If the chain takes longer than expected, you may need to keep an eye on your mortgage offer expiry date.

How long does a moving home mortgage take?

The mortgage application may take a few weeks, but the full moving process can take longer.

The mortgage application itself may take a few weeks, but the full moving process can take longer because it also depends on the property search, valuation, survey, legal checks and chain.

Many movers follow a timeline that starts with checking equity and affordability, then moves through Agreement in Principle, full application, mortgage offer, exchange and completion.

What costs should I budget for when moving home?

Moving costs can include more than your deposit and monthly mortgage payment.

You may need to budget for stamp duty, estate agent fees, solicitor fees, survey costs, removals, mortgage fees, early repayment charges and setup costs after completion.

It is also worth keeping a cash buffer rather than using every pound of available equity as your deposit.

What mortgage type is best when moving home?

The best mortgage type depends on whether you want certainty, flexibility or a balance of both.

There is no single best mortgage type for every mover.

A fixed-rate mortgage may suit you if you want payment certainty. A tracker or variable product may suit you if you want more flexibility and can handle payment changes. The right choice depends on your budget, plans, risk comfort, term, fees and whether you may move again soon.

Can I move home if I am self-employed?

Yes, but lenders may ask for more evidence of your income.

Yes, self-employed applicants can move home and apply for a new mortgage.

Lenders may ask for extra evidence, such as tax calculations, tax year overviews, accounts or business bank statements. Different lenders assess self-employed income in different ways, so lender choice can make a difference.

When should I speak to a mortgage broker about moving home?

It is usually worth speaking to a broker before you start making offers.

It is worth speaking to a broker before you start making offers, especially if you need to borrow more, port your mortgage, work around early repayment charges or sell and buy at the same time.

Early advice can help you understand your budget, compare your options and avoid committing to a property before the mortgage side is clear.
