Retirement interest-only mortgages explained
A retirement interest-only mortgage lets older homeowners borrow against their home and pay only the interest each month. The amount borrowed does not reduce. It is usually repaid from the sale of the home when the last borrower dies, moves into long-term care or sells. Payments must stay affordable throughout.
How a retirement interest-only mortgage works
With a retirement interest-only (RIO) mortgage, you borrow a lump sum secured on your home, which you continue to own. You pay the interest monthly, so the balance usually stays the same. There is typically no fixed end date: the capital is repaid when the home is sold, or by family or the estate from other funds. People often use one to repay an interest-only mortgage that is ending, help family or improve their home.
RIO vs standard interest-only
A standard interest-only mortgage has a fixed term, and you must repay the capital when it ends. A RIO mortgage usually has no fixed term, so the main test is whether you can keep up the interest for life. See RIO vs standard interest-only mortgages.
RIO vs equity release
With a lifetime mortgage, the most common type of equity release, there are usually no monthly payments and interest is added to the loan, so the debt grows. With a RIO mortgage the debt does not grow while payments are kept up, which can leave more for your estate, but it depends on reliable income. RIO mortgages generally do not include the no negative equity guarantee that Equity Release Council members offer. Our guide to RIO versus equity release explains more.
Who can get a RIO mortgage?
Criteria vary, but you will usually need to:
- meet the lender's minimum age, often 50 or 55, though some set it higher
- own a UK home that is your main residence and meets the lender's property criteria
- have reliable retirement income that covers the interest, and acceptable credit history
Many lenders set no maximum age. Our guide to RIO eligibility and affordability covers the checks, and interest only mortgages for over 60s explains how lenders' age limits work for standard interest-only borrowing.
How affordability is assessed
Lenders look at retirement income such as pensions, annuities and investment income. For a joint mortgage, they usually check that payments would stay affordable for the surviving partner, whose income may fall. The RIO affordability calculator gives a rough idea.
How much you may be able to borrow
The maximum loan is set as a percentage of your home's value, the loan-to-value (LTV), typically around 40-60% depending on lender, age and property. Affordability often limits borrowing first.
What it costs
The main cost is the monthly interest. Rates may be fixed for a period or variable, so payments can change. Rates vary between lenders and change often. Arrangement, valuation, advice and legal fees may apply, and some products have early repayment charges.
What happens if you miss payments
A RIO mortgage is secured on your home. Missed payments can lead to arrears and charges and, in serious cases, repossession. Contacting the lender early usually leaves more options open.
Pros and cons of a retirement interest-only mortgage
Possible advantages:
- You keep ownership of your home.
- The debt usually does not grow, so more may pass to your estate than with a lifetime mortgage.
- There is usually no end date to plan repayment for.
Possible drawbacks:
- You must keep up payments for life, even if income falls.
- Your home may be at risk if you do not.
- You may borrow less than with equity release, and variable rates can rise.
Alternatives to consider
- Downsizing: moving somewhere smaller, with no ongoing borrowing.
- Equity release: no monthly payments, but the debt usually grows.
- Extending an interest-only term or switching to repayment.

Regulation and advice
RIO mortgages are regulated by the Financial Conduct Authority (FCA) like other residential mortgages. An FCA-regulated mortgage adviser can compare them with your other options.

Frequently asked questions
Do I have to make monthly payments on a retirement interest-only mortgage?
Yes. You pay the interest every month for as long as the mortgage runs, and lenders check this is affordable from your retirement income. The amount borrowed is usually repaid from the sale of your home. Equity release works differently, with no monthly payments required.
When is a RIO mortgage repaid?
Usually when the last borrower dies, moves into long-term care or sells the home. The loan is normally repaid from the sale, although family or the estate may repay it from other money. Repaying earlier may involve an early repayment charge, depending on the product.
What happens to a joint RIO mortgage if one of us dies?
The mortgage usually continues for the surviving borrower, who must keep paying the interest. Lenders therefore normally check affordability on the survivor's income alone, which may be lower if a pension reduces on death. The RIO affordability calculator can help you think this through.
Can a RIO mortgage pay off an existing interest-only mortgage?
Often, yes. This is a common reason people consider one, particularly when an interest-only term is ending without a repayment plan. You would still need to meet the lender's age, income and property criteria. See interest-only mortgage ending options for the wider choices.
Is there a maximum age for a RIO mortgage?
Many RIO lenders set no maximum age, because the loan is repaid when the home is sold rather than by a fixed date. Minimum ages vary, often 50 or 55. Affordability from reliable retirement income matters most. Our RIO eligibility guide explains the usual checks.
Are retirement interest-only mortgages regulated?
Yes. They are regulated by the Financial Conduct Authority (FCA) like other residential mortgages, so lenders must assess affordability and you can complain to the Financial Ombudsman Service if something goes wrong. An FCA-regulated mortgage adviser can help you compare a RIO mortgage with other options.
