Understanding Retirement Interest-Only Mortgages
What Is A Retirement Interest-Only (RIO) Mortgage?
A Retirement Interest-Only (RIO) Mortgage is designed for homeowners aged 55 and above who wish to manage borrowing in later life while retaining full ownership of their home.
With a RIO mortgage:
- You pay monthly interest only, keeping repayments more affordable and predictable.
- The loan balance remains unchanged until a life event occurs, such as the sale of the home, a move into long-term care, or the passing of the borrower.
- There is no fixed end date, and your right to remain in the property is maintained.
Key Benefits of a RIO Mortgage
Manageable Monthly Payments
Interest-only payments make budgeting in retirement more straightforward compared to traditional repayment mortgages.
Flexibility and Control
A RIO mortgage allows you to:
- Release equity without downsizing
- Fund home improvements, holidays, or lifestyle costs
- Maintain financial independence using the value of your home
Eligibility Criteria
To be eligible, most providers require the following:
- Age: 55 or over (based on the youngest applicant)
- Income: A stable pension or retirement income sufficient to cover monthly interest payments
- Affordability: You must meet standard lender affordability assessments
- Property and loan: The property value and loan size must fall within the lender’s criteria
Risks and Considerations
While offering useful flexibility, a RIO mortgage may not suit everyone. Key considerations include:
- Impact on your estate: The capital balance remains and is repaid from the eventual sale of the property, which reduces what you can leave behind.
- Early repayment charges (ERCs): These may apply if the mortgage is repaid earlier than agreed.
- Affordability risk: If your income falls, or your health changes, you may find it harder to maintain the required interest payments.
Comparing RIO Mortgages with Lifetime Mortgages
Feature | RIO Mortgage | Lifetime Mortgage |
---|---|---|
Monthly Payments | Required (interest only) | Optional |
Ownership | Full ownership retained | Full ownership retained |
Repayment | From the property sale after a life event | From the property sale after a life event |
Impact on Equity | Equity is largely preserved | Equity may reduce over time due to compound interest |
Common Uses of RIO Mortgages
Clients often use a RIO mortgage to:
- Pay off an existing mortgage approaching maturity
- Fund renovations or home adaptations
- Supplement pension income in a sustainable way
- Support younger generations, including gifting deposits to children or grandchildren
Is a RIO Mortgage Right for You?

A Retirement Interest-Only mortgage may be suitable if you:
- Have a stable income that supports monthly interest payments
- Wish to remain in your home without downsizing
- Prefer predictable monthly outgoings over the compounding structure of a lifetime mortgage
Before proceeding, it is important to:
- Assess the long-term implications for your estate
