Frequently Asked Questions
What is a retirement interest-only mortgage?
A RIO mortgage is an interest-only mortgage with no fixed end date. You pay only the interest each month and the capital is repaid when the property is sold, typically when you die, move into long-term care, or choose to sell. Unlike equity release, you retain full ownership and make regular monthly payments.
Who qualifies for a RIO mortgage?
You must be aged 55 or over. Lenders assess affordability based on your retirement income including pensions, investment income, and rental income. They stress-test at higher rates. Maximum LTV is typically 50-65%. You need a good credit history but the criteria is generally more flexible than standard mortgages.
How is a RIO different from equity release?
With a RIO, you make monthly interest payments so the debt does not grow. With equity release (lifetime mortgage), interest typically rolls up, increasing the debt over time. RIO mortgages are cheaper long-term but require regular income to make payments. Equity release has no monthly payments but can significantly reduce your estate.
Can I switch from a standard mortgage to RIO?
Yes, many borrowers switch to RIO when their existing mortgage term expires and they cannot get a new standard mortgage due to age. This avoids being on the lenders standard variable rate. Some lenders will transition existing customers to RIO products without a full new application.
What happens if I cannot make payments?
If you can no longer afford the monthly interest payments, lenders must work with you to find a solution. Options include switching to equity release, downsizing, or seeking family support. Lenders are regulated by the FCA and must treat customers fairly. Repossession is a last resort.
