Retirement interest-only mortgage: Is it for you?

A retirement interest-only mortgage lets you pay the interest each month, with the loan usually repaid when the property is sold later.

A retirement interest-only mortgage, often called a RIO mortgage, lets you pay the interest each month while the original amount you borrow stays outstanding. You normally repay the capital later, usually when the final borrower dies, moves permanently into long-term care or the property is sold.

A RIO mortgage may suit you if you want to stay in your home, remortgage or replace an existing interest-only mortgage. However, you still need reliable income, enough equity and a repayment plan that fits the lender’s criteria.

Before choosing a RIO mortgage

PAYMENTS

Pay the interest each month

Your monthly payment normally covers the interest, so the capital usually stays outstanding.

INCOME

Show reliable retirement income

Lenders assess pension, employment, investment and other reliable income to check affordability.

CAPITAL

Plan how to repay the loan

The capital remains outstanding, so you need to understand when and how the plan will eventually repay it.

ALTERNATIVES

Compare other later-life routes

Standard mortgages and lifetime mortgages work differently, so compare payments, overall cost and the impact on your equity.

What is a retirement interest-only mortgage?

First, compare a RIO mortgage with other interest-only borrowing. You pay the interest each month, while the capital stays outstanding.

Unlike many standard interest-only mortgages, a RIO does not always have a fixed end date. Instead, the plan usually ends when the final borrower dies, moves permanently into long-term care or the property is sold. The sale proceeds then repay the capital.

Lenders set their own rules for minimum age, income and property criteria, so the options available can vary. The Financial Conduct Authority regulates RIO mortgages under its mortgage rules.

How does a RIO mortgage work?

In practice, a RIO keeps the interest and capital separate. You pay the interest due each month, so the original loan amount usually stays the same unless you make any permitted capital repayments.

For example, borrowing £100,000 at an illustrative rate of 5.75% would create a monthly interest payment of about £479.

Illustration only. The calculation assumes an interest-only payment of 5.75% on £100,000 and no capital repayments. Actual rates, fees and payments will vary.

By contrast, a repayment mortgage reduces the capital as you make each monthly payment. With some lifetime mortgages, you can choose not to pay the interest, which allows the provider to add it to the balance instead.

Could a RIO mortgage suit you?

Next, consider whether the structure fits your finances and plans. A RIO may suit you if you can afford the monthly interest, have enough equity and accept that the capital usually stays outstanding.

Reliable retirement income

Lenders assess pension, employment, investment and other reliable income to check whether you can maintain the monthly interest payments.

Age and eligibility

Lenders set their own minimum ages and eligibility rules, so the products available can vary.

Property and equity

Your property value, current mortgage, loan amount and loan-to-value can affect your options. The property must also meet the lender’s criteria.

A clear repayment plan

The lender will want to understand how you plan to repay the capital when the mortgage ends.

For borrowers exploring interest-only mortgages for over 60s, a RIO may be one route to consider. However, you still need to meet the lender’s income, affordability, property and equity criteria.

RIO mortgage or lifetime mortgage?

However, a RIO is not the only later-life option. Both RIO and lifetime mortgages can support borrowing later in life, but they handle interest and repayment very differently.

RIO MORTGAGE

Pay interest each month

You pay the interest each month, so the capital usually stays the same unless you make permitted capital repayments.

Meet affordability checks

Lenders assess your retirement income and other commitments to check whether you can maintain the monthly interest.

Capital remains outstanding

The plan normally repays the capital later, usually from the sale of the property.

LIFETIME MORTGAGE

Monthly payments may be optional

Depending on the product, you may make payments or allow the provider to add unpaid interest to the balance.

Interest can compound

If you leave the interest unpaid, compound interest can increase the amount you owe over time.

Your remaining equity can reduce

A growing balance can reduce the equity left in your home and affect inheritance or future choices.

RIO mortgage rates and costs

Once you understand the structure, compare the cost. Lenders price RIO mortgages differently, and your rate can depend on your loan-to-value, loan amount, property and the lender’s criteria.

However, the interest rate is only one part of the cost. Because the rate sets your monthly interest payment, a rate change can also change what you pay each month.

Because the rate determines the monthly interest, a rate change can also change your payment.

Benefits and trade-offs of a RIO mortgage

Finally, weigh the potential benefits against the trade-offs. A RIO can reduce the monthly payment compared with a repayment mortgage, but the capital normally remains outstanding.

POTENTIAL BENEFITS

Lower monthly payments

Because you only pay the interest, a RIO can cost less each month than a repayment mortgage with the same balance and rate.

Keep interest from rolling up

Paying the interest each month prevents that unpaid interest from being added to the loan balance.

Stay in your home

A RIO may help you remortgage or replace an existing interest-only loan without moving home.

IMPORTANT TRADE-OFFS

Capital stays outstanding

Your normal monthly payments do not usually reduce the original amount borrowed.

Income must cover the interest

You need enough reliable income to maintain the monthly payments throughout the mortgage.

Rates and circumstances can change

A higher rate or lower income could make the monthly interest harder to manage, and early repayment charges may apply.

WORTH KNOWING

A lower monthly payment does not mean you are reducing the debt. With a RIO mortgage, the capital usually remains outstanding until the plan ends.
