Later-life borrowing with a monthly interest payment and no fixed end date - the loan is repaid when the home is eventually sold. A middle path between a standard mortgage and equity release.
No fixed end date - runs until sale, death or long-term care
Interest paid monthly, so the debt does not grow

A retirement interest only (RIO) mortgage is a loan for older borrowers where you pay just the interest each month and the loan itself is repaid when the property is sold - normally when you die or move into long-term care. There is no fixed term to outlive, and because interest is paid monthly, the amount owed never grows.
RIO lending answers a genuine gap: standard mortgages impose maximum ages, while equity release rolls interest up against the value of the home. A RIO sits between the two - real monthly payments, affordability properly checked, and the equity you keep is protected from compounding interest.
We arrange both new RIO mortgages and RIO remortgages across all of the UK - and on every remortgage, the valuation and legal fees are free.
You borrow against your home and pay the interest each month - nothing else
The balance stays level; it does not reduce, and crucially it does not grow
There is no fixed end date: the loan runs until the home is sold, you die or you move into long-term care
The sale of the home then repays the loan, with everything above the balance going to you or your estate
Most RIO products are for borrowers from around age 55 upwards, with lender variations
Common uses: staying in the family home after an interest-only mortgage matures, raising money in later life for home adaptations or helping family, buying a retirement property, or replacing a standard mortgage that has hit its lender's age limit.
RIO vs equity release
RIO mortgages and lifetime mortgages (the main form of equity release) both run until sale, death or care - the difference is what happens to the interest:
RIO Mortgage vs Lifetime Mortgage
RIO mortgage
Lifetime mortgage (equity release)
Monthly payments
Yes - interest every month
Optional or none
Does the debt grow?
No - interest is paid as it arises
Yes, where interest rolls up
Affordability checks
Full checks on retirement income
Limited - lending is age and property based
Equity left in the home
Preserved at the loan amount
Reduces as interest compounds
If payments become unaffordable
Home at risk - payments are required
No required payments to miss
Which suits you depends on income, inheritance priorities and how much you want to borrow.
In short: if you can comfortably afford a monthly interest payment from retirement income, a RIO keeps the debt frozen and protects the equity your estate inherits. If reliable payments are the problem, RIO is the wrong tool - and we say so rather than force the fit.
RIO remortgages
A RIO remortgage replaces an existing mortgage with a RIO - the route our clients ask about most often in these situations:
An interest-only mortgage is maturing and the lender wants repayment, but you want to stay in the home - a RIO clears the old lender and keeps the payments you are already used to
A standard mortgage is ending against a lender age limit and needs replacing with something designed for retirement
An existing RIO or later-life deal is simply uncompetitive and worth switching
You own the home outright and want to raise money in later life with a level, non-growing debt
As with every remortgage we arrange, the valuation and legal fees on a RIO remortgage are free. If you are weighing a RIO against simply extending an interest-only deal, our interest only mortgages page covers that side of the comparison.
Affordability in retirement
Because a RIO has required monthly payments, lenders assess retirement income properly:
State, workplace and private pensions - in payment or evidenced as projections
Annuity, investment and rental income
Earnings, where you are still working, tapering to pension income later
For couples: the survivor test - the payment must remain affordable for each of you alone, on the income that would remain if the other died first
The survivor test is the one that most often shapes the loan size, and it exists for a serious reason: the home is at risk if the payments stop. Getting the evidence lined up - pension statements, projections, annuity schedules - is much of the work, and we handle it with you.
Costs and fees
Valuation and legal fees - free when your RIO is a remortgage, as on all remortgages we arrange
Lender arrangement fee on some products - compared on overall cost

Frequently Asked Questions
What is the difference between a RIO mortgage and equity release?
With a RIO you pay the interest every month, so the debt stays level and your equity is preserved; affordability is fully checked. With a lifetime mortgage (equity release) payments are optional or absent and interest can roll up, growing the debt against the home's value.
When does a RIO mortgage end?
There is no fixed term. The loan is repaid from the sale of the property when you die or move into long-term care - or earlier if you choose to sell or repay. For couples it runs until the second of you no longer lives in the home.
Can I repay some of the capital on a RIO?
Usually yes, within the product's overpayment allowance - reducing the balance cuts the monthly interest and leaves more equity in the estate. Repaying in full early may trigger an early repayment charge depending on the product; we set those terms out before you commit.
My interest-only mortgage is ending - is a RIO the answer?
It is one of the main ones. A RIO remortgage repays the maturing lender, keeps you in the home and keeps payments similar to what you already manage. Downsizing, equity release or a standard later-life term are the alternatives - we compare all of them with you.
How do lenders assess a couple for a RIO?
Both incomes are assessed now, and then each of you is tested alone: the payments must stay affordable for the survivor on the income that would remain - typically reduced pensions - if the other died. This survivor test often sets the maximum loan.
Does a RIO mortgage reduce my family's inheritance?
The loan itself comes out of the sale proceeds, but because interest is paid monthly the debt never grows - unlike rolled-up equity release, where compounding interest erodes the remaining equity over the years. What you borrow is what the estate eventually repays.
