How does income affect my eligibility for a RIO mortgage?

13th February 2026

By Simon Carr

A Retirement Interest-Only (RIO) mortgage is a specialised product designed for older homeowners who need to release equity or refinance an existing loan but cannot meet the standard repayment criteria for a traditional mortgage, often due to age restrictions or declining working income. Crucially, while RIO mortgages defer the repayment of the capital until a later life event (such as the sale of the property, or the death or entry into long-term care of the last surviving borrower), lenders require absolute proof that the borrower can afford the monthly interest payments throughout the entire term.

How Does Income Affect My Eligibility for a RIO Mortgage?

The role of income in securing a RIO mortgage differs significantly from traditional mortgages. While a standard residential mortgage focuses on current salary projections over a fixed term (e.g., 25 years), a RIO mortgage often has no fixed term, lasting potentially several decades. Therefore, lenders must assess the durability and reliability of your income far into the future.

The primary concern for a RIO lender is confirming that the borrower can comfortably meet the monthly interest payments without defaulting. This assessment focuses on sustainability rather than just the total amount.

Understanding Retirement Interest-Only (RIO) Mortgages

A RIO mortgage is designed specifically for people aged 55 and over (though typical minimum age requirements are often higher, around 60 or 65). The central feature is that you pay the interest every month, but the capital amount remains unchanged. The capital is only repaid when a specific life event occurs, usually upon the sale of the property after the borrower or co-borrowers have passed away or moved into care.

Because the loan is potentially open-ended, the lender needs concrete reassurance that your monthly income, particularly your post-retirement income, is robust enough to cover the interest payments for the duration.

The Core Affordability Test: Interest Servicing

For RIO mortgages, the income assessment process is rigorous and focused on long-term sustainability. Lenders apply strict affordability checks based on criteria set by the Financial Conduct Authority (FCA). You must demonstrate that your current and projected income can cover the interest payments, plus enough for general living expenses, often tested at a higher ‘stress-tested’ interest rate.

Assessing Current Working Income

If you are applying for a RIO mortgage before you officially retire, your current working income (salary, self-employment profits) will be considered. However, lenders will treat this income cautiously if you are close to retirement age (e.g., within 5–10 years). The lender will ask for evidence of your planned retirement date and use that to transition their focus to your future income streams.

If you are already retired, current employment income may be ignored entirely unless you can prove it is a reliable, ongoing income stream (e.g., a secured part-time contract that will last indefinitely).

The Importance of Sustainable Retirement Income

The most important factor determining your eligibility is the reliability and amount of your sustainable retirement income. Lenders favour guaranteed or highly predictable sources of income.

  • State Pension: This is considered highly reliable. Lenders will ask for proof of your entitlement and projected start date. It is advisable to know exactly what you are due by checking your State Pension forecast.
  • Defined Benefit (DB) Pensions: Often called final salary schemes, these are highly valued as they provide a guaranteed, lifelong income stream, usually indexed to inflation.
  • Defined Contribution (DC) Pensions: Income drawn from personal pensions (SIPP, etc.) is assessed based on whether you are taking an annuity (guaranteed income) or flexible drawdown (non-guaranteed income). If using drawdown, the lender will assess the capital value of the fund and the sustainability of the required withdrawals.
  • Investment Income: Income derived from trusts, rental properties, or dividends may be considered, but lenders typically require proof of consistent performance over several years and may apply large discounts to the total amount to account for volatility.
  • Benefits: Certain benefits, such as Attendance Allowance or Disability Living Allowance, may be considered, especially if they are long-term and non-means-tested.

Lenders typically operate on the principle of ‘income floors’. If your verified income falls below a certain threshold (e.g., £15,000 per year), you may struggle to meet affordability criteria, regardless of the size of the loan you require.

How Lenders Verify Income

The verification process is thorough and usually involves providing extensive documentation:

  1. Pension Statements: Annual statements showing projected income and lump sums.
  2. Bank Statements: Typically 3–6 months of statements to verify the actual receipt of pension payments, benefits, or rental income.
  3. Tax Returns (SA302s): If you receive self-employment income or rental income, these will be required for the last 2–3 years.
  4. Confirmation of Benefits: Letters from the Department for Work and Pensions (DWP) confirming current and future benefit entitlements.

Calculating Loan-to-Value (LTV) and Maximum Borrowing

While income dictates affordability (how much interest you can pay), the value of your property dictates the maximum amount you can borrow (the capital amount). RIO mortgages typically have stricter Loan-to-Value (LTV) limits than traditional mortgages, often capped between 50% and 60% of the property’s value.

Lenders use a combination of these factors:

  1. Affordability Check: Based on your income, the lender calculates the maximum interest payment you can sustain.
  2. LTV Check: Based on the property valuation, the lender calculates the maximum capital amount they will lend.

The lower of the two resulting figures will be your maximum available borrowing amount. If your income is deemed low, it will severely restrict the loan size, even if you have significant equity in your property.

The Role of Credit History and Financial Health

Even if your income is sufficient, lenders will assess your overall financial health to ensure reliability. A poor credit history, defaults, or county court judgments (CCJs) indicate a higher risk of defaulting on the interest payments.

Lenders will perform a comprehensive credit check to review your track record managing debt. While a perfect score is not always required, proof of consistent payment behaviour is essential for a loan that could last decades. If you are unsure about your current standing, checking your credit report beforehand is highly recommended. Get your free credit search here.

If you fail to meet the interest repayments on a RIO mortgage, you will be in breach of the loan agreement. This can lead to serious consequences, including legal action, increased interest rates, additional charges, and, ultimately, repossession of the property. Your property may be at risk if repayments are not made.

People also asked

Can I get a RIO mortgage if I only have State Pension income?

While the State Pension is highly reliable, relying solely on it may make it difficult to qualify for a substantial RIO mortgage, as the income amount might not meet the lender’s minimum affordability threshold after accounting for living costs and stress-tested interest rates.

Do RIO lenders accept income from property rental?

Yes, most RIO lenders will consider rental income, provided you can demonstrate that the income is consistent, stable, and has been generated reliably over the last few years, typically evidenced by tax returns (SA302s) and tenancy agreements.

What happens if my retirement income decreases after I take out the RIO mortgage?

If your income decreases and you can no longer afford the interest payments, you must inform your lender immediately. If you consistently fail to make payments, the lender has the right to treat the loan as defaulted, which could lead to increased charges or the forced sale of the property to cover the outstanding debt.

Is a RIO mortgage the same as equity release?

No, they are different. Standard equity release (like a Lifetime Mortgage) allows the interest to roll up and compound, meaning you typically make no monthly payments. A RIO mortgage requires you to make monthly interest payments; only the capital repayment is deferred.

How old do I need to be to get a RIO mortgage?

While the FCA allows RIO mortgages for those aged 55 and over, many lenders set their own minimum entrance age, often between 60 and 65, to better align the product with standard retirement ages.

Can I still work part-time after getting a RIO mortgage?

Yes, absolutely. Having part-time employment income after the mortgage is secured poses no issue, provided you initially proved you could afford the interest payments using your core, sustainable retirement income (pensions, benefits).

Summary of RIO Affordability

Securing a RIO mortgage is a testament to the longevity and certainty of your retirement finances. Lenders must be confident that the income you receive will not only continue for life but will be sufficient to cover the interest payments comfortably, even if interest rates rise in the future.

If you are considering a RIO mortgage, the key is preparation. Gather comprehensive documentation relating to all pension provisions, state benefits, and investment income streams. Consulting a qualified, independent financial adviser specialising in later-life lending is essential to navigate the detailed affordability requirements and ensure the product fits your long-term financial goals without jeopardising your security.
