Buy-to-let questions answered

Below are some of the most common questions landlords ask when arranging a buy-to-let mortgage.

Most buy-to-let lenders require a minimum deposit of 20% to 25% of the property’s value.

However, the required deposit can vary depending on the:

  • lender
  • property type
  • expected rental income from your experience as a landlord

Some lenders may require 30% or more, particularly for new landlords or higher-risk properties.

A larger deposit can also provide access to lower interest rates and a wider choice of lenders.

Buy-to-let mortgages are primarily assessed based on the property’s expected rental income.

Most lenders require the rental income to cover 125% to 145% of the mortgage payment when tested against a higher “stress rate”.

This is known as the Interest Coverage Ratio (ICR) and helps ensure the property can support the loan even if interest rates rise.

Some lenders may also consider your personal income, particularly if rental income falls slightly below their required threshold.

Yes, many lenders are willing to lend to first-time landlords.

However, lenders may apply slightly stricter criteria, such as:

  • higher deposit requirements
  • minimum personal income levels
  • restrictions on certain property types

Working with a mortgage broker can help identify lenders that are comfortable with first-time landlords, which can significantly improve the chances of approval.

Some landlords purchase buy-to-let properties through a limited company structure.

This can provide potential tax advantages, particularly for higher-rate taxpayers, because mortgage interest may be treated differently than for personally owned properties.

However, limited company mortgages can also involve:

  • slightly higher interest rates
  • additional legal and accounting requirements
  • different lender criteria

For this reason, many landlords consult both a mortgage adviser and an accountant before deciding which structure best suits their long-term plans.

Yes, many landlords grow their portfolio by remortgaging an existing property to release equity.

If the property’s value has increased or the mortgage balance has reduced, the additional equity can often be used as a deposit for another buy-to-let purchase.

Lenders will still assess affordability, rental income, and the overall loan-to-value across the portfolio before approving the new borrowing.

Standard buy-to-let mortgages are typically used to purchase residential rental properties, such as flats or houses.

However, some lenders also offer specialist products for:

  • HMOs (Houses in Multiple Occupation)
  • multi-unit freehold blocks
  • student accommodation
  • holiday lets or short-term rentals

These property types often involve different lending criteria and deposit requirements, so specialist lenders may be required.

The amount you can borrow is usually based on the expected rental income from the property, rather than your personal salary.

Lenders calculate borrowing capacity using the Interest Coverage Ratio, ensuring that rental income comfortably exceeds mortgage payments.

In many cases, landlords can borrow around 70% to 75% of the property value, although the exact amount depends on rental income, lender stress tests, and deposit size.

Yes. Buy-to-let purchases are usually subject to higher stamp duty rates than residential purchases.

Landlords typically pay a 5% surcharge on top of standard stamp duty rates.

The exact amount depends on the property’s purchase price and your existing property ownership.

Because tax rules can change, it is important to check current stamp duty rates before purchasing.
