Many borrowers reach later life with a mortgage still outstanding. A retirement interest-only (RIO) mortgage lets older homeowners pay only the interest each month, with the capital repaid when the property is sold, usually on death or a move into long-term care. It is a niche product but increasingly useful as retirement ages rise and interest-only options on the high street narrow.
The Bank of England held Bank Rate at 3.75% at its September 2026 meeting, by a 6–3 vote with three members preferring a rise to 4%, and the next decision is due on 5 November 2026. With CPI inflation at 3.1% in the 12 months to August, borrowers should not assume rates will fall soon.
How a RIO mortgage works
Unlike a standard interest-only mortgage with a fixed term, a RIO has no set end date. The loan stays in place for as long as the borrower lives in the property and can afford the interest, and is repaid from the proceeds of sale. Because there is no required capital repayment during the term, the lender’s main concern is that the interest remains affordable from pension and other retirement income.
Who may qualify
- Applicants typically need to be at least in their mid-fifties, though lender minimum ages differ.
- Income is usually drawn from pensions, annuities, investment income, rental income or continuing earnings.
- Maximum loan-to-value is often lower than on standard mortgages, with many lenders capping borrowing well below 60% of the property value, to leave room for rising balances if payments are missed.
- Joint applications are usually assessed on the basis of both incomes, and what would happen to the loan if one borrower dies or moves into care.
Affordability under the FCA rules
Residential lending is regulated, so lenders must assess whether repayments are affordable now and in retirement. Pensions are checked for permanence, and lenders consider outgoings and any stress on payments if rates rise. With Bank Rate at 3.75% and further moves uncertain, a stress test can reduce the amount available compared with the headline figure.
RIO or a standard remortgage?
If an existing repayment or interest-only mortgage is ending, the choice is not only RIO. A remortgage onto a longer repayment term, a lender’s own product switch (see our comparison of a product transfer vs remortgage), downsizing or equity release may fit better depending on income and goals. Equity release products are separately regulated and can be considered alongside, but affect inheritance and means-tested benefits, so independent legal advice is required.
Points to think about
- The loan does not reduce over time, so the balance at the end equals today’s borrowing plus any unpaid interest.
- Rates on RIO are generally higher than on mainstream mortgages.
- Family should be told about the plan, since sale of the home may be needed to repay.
- Early repayment charges can apply on fixed deals.

Frequently asked questions
Is a RIO mortgage the same as equity release?
No. A RIO is a mortgage where interest is paid monthly; equity release usually rolls interest up and is regulated separately. They have different risks and costs, so compare them with advice.
What if my income falls?
If interest payments cannot be maintained, the lender may seek possession or require the property to be sold. Discuss any difficulty with your lender and broker early.
Can I move home with a RIO?
Some lenders allow porting subject to fresh affordability and valuation checks, but terms vary and early repayment charges may apply.
Do I need legal advice?
You should take independent legal advice, particularly where family members may inherit the property or have an interest in it.
