When people in later life think about borrowing against their home, a lifetime mortgage is usually the first thing they hear about. It’s heavily marketed, widely available, and the subject of countless TV adverts. But it isn’t the only option — and for some people, it isn’t the right one.
Retirement Interest Only mortgages — usually called RIOs — are a genuinely useful alternative that tends to get far less attention. This guide explains how they work, who they suit, and how they compare to a lifetime mortgage so you can make a more informed decision about which, if either, might be appropriate for you.
Important: Both lifetime mortgages and RIO mortgages are secured against your home. Think carefully before securing a loan against your property. Taking independent financial advice before making any decision is strongly recommended.
What is a Retirement Interest Only mortgage?
A Retirement Interest Only mortgage is essentially what it sounds like: an interest-only mortgage designed for older borrowers, where the capital is only repaid at the end of the mortgage term — which in this case means when you die, move into long-term care, or sell the property.
The key difference from a standard interest-only mortgage is that there’s no fixed end date and no requirement to have a separate repayment vehicle in place. The loan continues for as long as you remain in the property. Monthly payments cover only the interest, keeping the outstanding loan balance the same throughout.
The FCA reclassified RIO mortgages in 2018, making it easier for lenders to offer them and for advisers to recommend them. They’re now a mainstream option for later-life borrowing, though they remain less well-known than lifetime mortgages.
How does a RIO mortgage differ from a lifetime mortgage?
This is the question that matters most, so it’s worth being direct about the differences.
| Feature | RIO Mortgage | Lifetime Mortgage |
|---|---|---|
| Monthly payments | Yes — interest only | Usually no (optional with some products) |
| Loan balance over time | Stays the same | Grows as interest rolls up |
| Effect on estate | Lower — loan stays level | Higher — loan grows over time |
| Income requirement | Yes — to cover monthly interest | No — no monthly payments required |
| Minimum age | Typically 55+ | Typically 55+ |
| Repayment trigger | Death, long-term care, or sale | Death, long-term care, or sale |
| No-negative-equity guarantee | Not always included | Yes (Equity Release Council members) |
Why a RIO might be better than a lifetime mortgage
The central advantage of a RIO mortgage is straightforward: because you’re paying the interest each month, the loan balance doesn’t grow. With a lifetime mortgage, interest compounds over time and the loan can more than double over 15 or 20 years. For anyone concerned about the impact on their estate — particularly if they want to leave something to children or grandchildren — keeping the loan level is a meaningful difference.
RIO rates are also typically lower than lifetime mortgage rates, because the lender is receiving regular payments rather than deferring everything to the end.
If you have sufficient retirement income to comfortably cover monthly interest payments, a RIO mortgage will almost always leave more for your estate than an equivalent lifetime mortgage over the same period.
When a lifetime mortgage might be the better fit
A RIO mortgage requires you to make monthly payments — and those payments need to be affordable from your retirement income. If your income in retirement is limited, unpredictable, or likely to reduce over time, a lifetime mortgage — where no monthly payments are required — may be more appropriate.
Lifetime mortgages also offer drawdown facilities, where you can access money as and when you need it rather than taking a lump sum upfront. This can be more tax-efficient and cost-effective if you don’t need all the money at once. A standard RIO is a fixed loan amount, though some lenders do offer further drawdown options.
The right choice comes down to your income, your estate planning goals, and what you need the money for. These are conversations worth having properly — not decisions to make based on a TV advert.
Who is eligible for a RIO mortgage?
RIO mortgages are available to older borrowers — the minimum age varies by lender but is typically 55. Unlike standard mortgages, there is no maximum age, and there is no fixed end date to the mortgage term.
Affordability is assessed on your retirement income. Lenders will want to see that your income — from pensions, investments, rental income, or other sources — is sufficient to cover the monthly interest payment comfortably, and that it is expected to continue. The assessment is more straightforward than a standard mortgage because lenders aren’t projecting future employment income — pension income and similar is generally considered stable and predictable.
What about downsizing?
It’s worth mentioning downsizing as an alternative to both. If you own a property larger than you need, selling and moving to something smaller can release cash without any borrowing at all. No monthly payments, no interest, no impact on your estate beyond the reduced property value.
For some people this isn’t practical — the emotional attachment to a home, proximity to family, or the logistics of moving in later life can make downsizing feel like too much. But it’s worth considering honestly before committing to any form of later-life borrowing.
What other options exist?
Beyond RIO mortgages and lifetime mortgages, a few other options are worth being aware of:
- Standard interest-only mortgage into retirement — some lenders will extend or maintain an interest-only mortgage into retirement if income supports it, though this is less flexible than a RIO
- Part-and-part mortgages — a split between capital repayment and interest-only, which can suit those who want to keep some level of capital repayment going without the full commitment of a standard repayment mortgage. See our interest-only mortgage page for more on this.
- Unsecured borrowing — for smaller amounts, unsecured options may be available without putting your home at risk, though rates are typically higher
- Family arrangements — in some situations, family members may be in a position to help, which avoids any formal borrowing against the property

A RIO mortgage is a mortgage for older borrowers where you pay only the interest each month, keeping the loan balance the same. The capital is repaid when you die, move into long-term care, or sell the property. Unlike a lifetime mortgage, the loan does not grow over time.
With a RIO mortgage you make monthly interest payments, keeping the loan balance stable. With a lifetime mortgage, interest rolls up and the loan grows over time. A RIO mortgage is better for protecting your estate; a lifetime mortgage suits those who cannot or do not want monthly payments.
RIO mortgages are available to older borrowers, typically 55 and over. Affordability is assessed on retirement income — pension, investment income, or other regular income expected to continue.
Your retirement income — state pension, private or workplace pension, rental income, or investment income — needs to comfortably cover the monthly interest payment and be expected to continue.
In some cases yes, depending on your age, property value, and income. If you have a lifetime mortgage but have retirement income that could service interest payments, it may be worth exploring.
Yes. RIO mortgages are regulated by the FCA, which means you have the protections that come with regulated mortgage advice.
