A quick overview of retirement interest-only mortgages

While a lifetime mortgage is the most popular type of equity release in the UK, Retirement Interest-Only (RIO) mortgages are a distinct alternative. They allow homeowners, typically over the age of 55, to borrow against their property, but unlike lifetime mortgages, they require monthly interest payments. The loan balance is usually not repaid until they die or enter long-term care.

You can read more about them in our complete guide to retirement interest-only mortgages.

Here are the main features of RIO mortgages that distinguish them from regular home loans and lifetime mortgages:

  • They are specifically designed for older borrowers.

  • There are mandatory monthly interest payments (unlike lifetime mortgages where there are no mandatory payments).

  • You must prove affordability to ensure you can meet the monthly payments.

  • You must be a homeowner to qualify).

THINK CAREFULLY BEFORE SECURING OTHER DEBTS AGAINST YOUR HOME. YOUR HOME MAY BE REPOSSESSED IF YOU DO NOT KEEP UP REPAYMENTS ON A MORTGAGE OR ANY OTHER DEBT SECURED ON IT.

IF YOU ARE THINKING OF CONSOLIDATING EXISTING BORROWING YOU SHOULD BE AWARE THAT YOU MAY BE EXTENDING THE TERMS OF THE DEBT AND INCREASING THE TOTAL AMOUNT YOU REPAY.
