RIO Mortgage vs Standard Interest-Only: What's Different
The main difference between a retirement interest-only (RIO) mortgage and a standard interest-only mortgage is the end date. A standard interest-only mortgage has a fixed term, when the loan must be repaid. A RIO mortgage usually has no end date and is repaid when the home is sold after death or a move into long-term care.
With both, you pay only the interest each month. This guide compares their terms, repayment plans, affordability checks and what happens later in life. It is general information, not financial advice. For a full overview, see our guide to retirement interest-only mortgages.
RIO vs standard interest-only at a glance
| Standard interest-only | RIO mortgage | |
|---|---|---|
| End date | Fixed term agreed at the start | Usually none |
| Repayment plan | Credible plan required | Normally the sale of the home |
| Affordability | Monthly interest over the term | Monthly interest for life |
| Typical borrower | Any age, within lender limits | Older homeowners, often 55+ |
How much you can borrow also differs. With a RIO mortgage, the amount depends on your age and the value of your home. MoneyHelper says a RIO mortgage may allow borrowing of up to 50% to 60% of a home's value at age 50.
Term and end date
A standard interest-only mortgage runs for an agreed term, set when it was first taken out. When it ends, the whole balance falls due. If the repayment plan has fallen short, you may need to extend, switch or sell. Our guide to interest-only mortgages that are ending covers the usual choices.
A RIO mortgage removes that deadline. You keep paying the interest and the loan continues until the last borrower dies or moves into long-term care. The Financial Conduct Authority (FCA) introduced RIO mortgages as a distinct type of regulated mortgage in 2018.
Repayment plan requirements
For a standard interest-only mortgage, lenders must check that you have a credible way to repay the loan at the end of the term, such as savings, investments or the sale of another property.
For a RIO mortgage, the repayment plan is normally the eventual sale of your home. You do not usually need a separate savings plan, but the loan reduces what your home passes on.
How affordability is assessed
Both products need you to show you can afford the monthly interest. The difference is how long that must hold:
- Standard interest-only: lenders assess affordability over the term. If it runs into retirement, they may look at expected retirement income too.
- RIO: with no set end date, lenders look at income expected to last for life, such as pensions. For joint borrowers, they usually check the payments would still be affordable if one borrower died.
Our RIO eligibility and affordability guide explains these checks, and the RIO affordability calculator gives an indicative idea of what might be affordable. It is not a quote.
What happens at death or a move into care
With a standard interest-only mortgage, the loan is still owed if a borrower dies. A surviving joint borrower usually continues the mortgage but must still repay it at the end date.
With a RIO mortgage, the loan normally continues for a surviving joint borrower who can keep up the payments. It is repaid when the last borrower dies or moves into long-term care, usually from the sale of the home, within a period set by the lender.
Who each may suit
A standard interest-only mortgage may suit borrowers with a clear, realistic plan to repay by a known date who want the loan to end within their lifetime.
A RIO mortgage may suit homeowners in later life who can afford the interest from reliable retirement income and are comfortable with the loan being repaid from the home's sale. Equity release is an alternative for those who want no monthly payments, although interest then builds up instead. Our guide to RIO mortgage benefits for older homeowners explains more.

Frequently asked questions
Can I switch from a standard interest-only mortgage to a RIO mortgage?
Often, yes, if you meet a lender's age, income and property criteria. Some homeowners look at a RIO mortgage when their interest-only term is ending without enough to repay. The new lender repays the existing mortgage, so you need enough equity and affordable monthly interest. Fees and any early repayment charges on your current deal may apply.
Are RIO mortgage rates higher than standard interest-only rates?
It depends on the lender, the loan-to-value and market conditions at the time. RIO rates are not always higher or lower than standard interest-only deals, and both change over time. Comparing the total monthly cost and fees on current products with an FCA-regulated adviser gives a clearer picture than a general rate figure.
Do I need a repayment plan for a RIO mortgage?
Not usually in the same way. A standard interest-only mortgage needs a credible plan to repay by the end of the term. With a RIO mortgage, the loan is normally repaid from the sale of your home after death or a move into long-term care, so lenders focus on whether you can keep up the interest payments.
Can a RIO mortgage be repaid early?
Yes, a RIO mortgage can usually be repaid early, for example if you sell and move. An early repayment charge may apply during a fixed-rate period, depending on the product. Some lenders also allow part repayments. Our guide on repaying a RIO mortgage early explains what to check.
Is a RIO mortgage the same as equity release?
No. A RIO mortgage is a type of residential mortgage where you pay the interest every month, so the loan does not grow. A lifetime mortgage, the main type of equity release, usually has no monthly payments, so interest builds up and is added to the loan. Each option has different costs, checks and effects on inheritance.
