Getting a mortgage later in life used to be difficult — many lenders simply would not lend to older borrowers. Retirement interest-only mortgages, often called RIO mortgages, were created to address exactly that, and they have opened up options for people who thought their borrowing days were behind them.
What a RIO mortgage is
A retirement interest-only mortgage is designed for older borrowers, usually those over 55. As the name suggests, you pay only the interest each month, keeping the payments low and manageable. The original loan amount is not repaid through monthly payments — instead it is repaid in full when a defining event happens, typically when you move into long-term care, or when the property is sold, often on death.
Because you are only ever paying the interest, the monthly cost is much lower than a repayment mortgage, which can make borrowing affordable on a retirement income.
How it differs from equity release
RIO mortgages are often confused with equity release, but they work differently. With a RIO mortgage you make monthly interest payments, so the debt does not grow — the amount owed at the end is the amount you borrowed. With a lifetime mortgage (the most common form of equity release) you typically make no payments and the interest rolls up, so the debt increases over time. Which is more suitable depends entirely on your circumstances and what you want to achieve.
Who they suit
A RIO mortgage can suit older borrowers who can comfortably afford the monthly interest and want to keep the debt from growing — perhaps to release some equity, to buy a new home in retirement, or to move an existing interest-only mortgage that is coming to an end. Because the payments must be affordable on your retirement income, the lender will assess that income carefully.
Taking advice
Borrowing in later life is an area where advice really matters. A RIO mortgage, a standard later-life mortgage, and equity release are all different tools with different implications for your income, your estate and your options down the line. The right choice is personal, and it deserves proper consideration.
