Later-life mortgage advice
Retirement interest-only mortgages explained
A retirement interest-only mortgage, or RIO mortgage, lets you borrow against your home in later life while paying only the interest each month. The loan itself is normally repaid from the sale of your home when the last borrower dies or moves into long-term care.
The clear answer
What is a retirement interest-only mortgage?
A retirement interest-only mortgage is a regulated residential mortgage for older homeowners. You pay the interest every month, but you don’t repay the amount you borrowed during your lifetime. Instead, the loan is normally repaid when the property is sold, usually after the last borrower dies or moves permanently into long-term care.
Because you pay the interest in full each month, the amount you owe should stay the same rather than growing over time. That is the main difference from a roll-up lifetime mortgage, where interest is added to the loan and the balance increases.
There is usually no fixed end date, so you’re not faced with a deadline to repay the capital while you’re still living in the home. The trade-off is that the monthly payments are compulsory, and the lender will check that you can afford them now and in the future.
Step by step
How a RIO mortgage works.
The details vary by lender, but most retirement interest-only mortgages follow the same pattern.
You borrow a lump sum against your home
It might repay an existing interest-only mortgage that’s coming to an end, help family, fund home improvements or support a move.
You pay the interest each month
Payments are usually made from pension or other retirement income.
The balance normally stays level
As long as the interest is paid in full, the original loan doesn’t grow.
The loan is repaid later
Usually from the sale of the property when the last borrower dies or moves into long-term care. You can normally repay earlier, although early repayment charges may apply during a fixed or discounted rate period.
The balanced view
Who a RIO mortgage may suit.
A RIO mortgage works well for some people and badly for others. These are the common signs either way.
It may be worth considering if you:
- have an interest-only mortgage ending and can’t repay the capital, but can afford the monthly interest
- have reliable retirement income, such as a state, workplace or private pension
- want to avoid interest rolling up and keep more of your home’s value for your family
- want to stay in your home without a fixed date to repay the loan
It may not be right if:
- your income is tight, or would drop sharply if you or your partner died
- you don’t want any monthly payment commitment
- you’d rather downsize and reduce your borrowing altogether
- you may need to raise more money from your home in the future
Side by side
RIO mortgage vs lifetime mortgage vs standard interest-only.
The three can look similar, but they work very differently once you look at payments, the balance and when the loan ends.
The right option depends on your income, how much you need, your plans for your home and how important leaving an inheritance is to you. We’ll compare all three with you before making any recommendation.
Retirement interest-only mortgage
- Monthly payments: interest must be paid every month.
- Does the balance grow? Not if interest is paid in full.
- When it’s repaid: normally on death or a move into long-term care.
- Affordability check: yes, including later life.
- If payments are missed: arrears and possible repossession.
Lifetime mortgage (equity release)
- Monthly payments: usually optional. Interest can roll up, or you can make voluntary repayments.
- Does the balance grow? Yes, if interest rolls up.
- When it’s repaid: normally on death or a move into long-term care.
- Affordability check: usually not for roll-up plans.
- If payments are missed: lower risk on roll-up plans, as no payments are required.
Standard interest-only mortgage
- Monthly payments: interest must be paid every month.
- Does the balance grow? Not if interest is paid in full.
- When it’s repaid: at the end of a fixed term.
- Affordability check: yes, including a plan to repay the capital.
- If payments are missed: arrears and possible repossession.
The lender’s checks
How lenders assess affordability.
Because the monthly payments are compulsory, the lender needs to be satisfied that you can keep up with them for the rest of your life.
Your income
State pension, workplace and private pensions, and any other reliable income. Lenders have their own rules on which income they’ll accept and the evidence they need.
Your outgoings
Your regular spending and any other borrowing.
The future
Where there are two borrowers, lenders normally check that the payments would still be affordable for the survivor on a single income after one of you dies. This is often the deciding factor.
Credit and property
Your credit history is considered, and the home must be acceptable to the lender. It is usually your main residence.
Repaying the loan
What happens when the mortgage ends.
The mortgage normally ends when the last borrower dies or moves permanently into long-term care. The property is then usually sold and the loan repaid from the proceeds. Anything left over goes to your estate.
Your family may be able to repay the loan from other funds if they’d like to keep the property, subject to the lender’s terms and timescales.
You can also choose to repay the mortgage earlier, for example if you sell and downsize. Check whether early repayment charges apply first.
Rates and the full cost
RIO mortgage rates: what affects them.
RIO mortgage rates vary between lenders and change regularly, so we don’t publish rates on this page. The rate you’re offered depends on the factors listed in the panel on this section.
A low rate isn’t the whole story. Arrangement fees, early repayment charges and flexibility can all matter more over the long term. When we compare RIO mortgages for you, we set out the full cost, not just the headline rate. If you’re also weighing up equity release, our guide to equity release interest rates explains how lifetime mortgage rates compare.
Costs and advice
What it costs.
The Mortgage Hive does not charge an adviser fee for later-life mortgage advice. Other costs can apply, such as lender arrangement fees, valuation fees and legal fees. We’ll explain these before you go ahead. Our guide to later-life lending costs and fees covers each one.
Before you decide
The risks to understand.
A RIO mortgage is a long-term commitment. These are the points to weigh up carefully.
Before deciding
Alternatives to consider.
Before recommending a RIO mortgage, we’ll look at whether something else would suit you better.
Downsizing
Could clear your mortgage and cut your outgoings.
A standard residential mortgage
May be possible if a term and repayment plan fit the lender’s criteria.
A lifetime mortgage
Avoids compulsory payments, although interest may roll up. An interest-paying lifetime mortgage can combine the two.
Savings or family support
May reduce or avoid the need to borrow.

Common questions
Retirement interest-only mortgage FAQs.
These answers are general. A recommendation can only be made after your circumstances and alternatives have been assessed.
Is a retirement interest-only mortgage the same as equity release?
No. A RIO mortgage is a standard residential mortgage with monthly interest payments that you must keep up. Equity release usually refers to a lifetime mortgage, where payments are normally optional and interest can roll up. Both let you stay in your home and are usually repaid when the property is sold, but they work very differently.
Can I use my pension income for a RIO mortgage?
Usually, yes. Lenders can consider state, workplace and private pension income, as well as other reliable income. Each lender has its own rules on which income it accepts and the evidence it needs, so we’ll check this for you before you apply.
What happens if my partner dies?
The mortgage normally continues for the surviving borrower, who keeps making the monthly interest payments. This is why lenders check at the outset that the payments would still be affordable on the survivor’s income. It’s worth planning for this together before you apply.
What happens if I can’t keep up the payments?
A RIO mortgage is a residential mortgage, so missed payments can lead to arrears and, ultimately, repossession. If you’re worried about affording the payments, speak to your lender early. You may also want to consider whether a lifetime mortgage or downsizing would be more suitable.
Can I fix the interest rate?
Many lenders offer fixed-rate periods, and some offer longer fixes. Product availability changes regularly. Fixing gives certainty over payments for that period but may come with early repayment charges if you repay early.
Can I repay a RIO mortgage early?
Usually, yes, for example if you sell and downsize. Early repayment charges may apply during a fixed or discounted rate period, so check your mortgage terms before you repay.
