What is the maximum loan-to-value (LTV) ratio on a RIO mortgage?
13th February 2026
By Simon Carr
Retirement Interest-Only (RIO) mortgages are specialist products designed for older homeowners, typically aged 55 and over, who need to raise capital or pay off an existing mortgage. Unlike standard residential mortgages, RIO mortgages have significantly stricter limitations regarding the Loan-to-Value (LTV) ratio.
Understanding what is the maximum Loan-to-Value (LTV) ratio on a RIO mortgage in the UK
The Loan-to-Value (LTV) ratio is a fundamental concept in UK mortgage lending, representing the size of the loan compared to the current valuation of the property, expressed as a percentage. For example, if your property is valued at £200,000 and you borrow £100,000, your LTV is 50%.
While standard residential mortgages often allow LTVs up to 90% or 95% for younger borrowers, the rules are distinctly different for Retirement Interest-Only (RIO) products. The maximum LTV available on a RIO mortgage rarely exceeds 60%, and for many specialist products, the cap might be set closer to 55% or even 50%.
Why are RIO LTVs Lower than Standard Mortgages?
The reduced LTV ceiling for RIO mortgages is a critical reflection of the unique risks associated with lending to retirees. These mortgages are designed to last for the rest of the borrower’s life, with the capital only being repaid upon a significant life event—usually the death or permanent move into care of the last surviving borrower. This extended, open-ended term necessitates a cautious approach from lenders.
- Affordability Risk: Although the borrower only pays the interest, lenders must be certain that this payment is sustainable for potentially decades. Retiree income is often fixed and non-increasing, meaning they have less capacity to absorb unexpected rate rises or financial shocks.
- Age of Borrowers: Lenders are mindful that the longer the term, the more time there is for potential property market volatility before the property is eventually sold to repay the capital. A lower LTV provides a larger equity buffer against potential future house price declines.
- Regulatory Requirements: RIO mortgages, while distinct from traditional equity release schemes (Lifetime Mortgages), are still subject to strict regulatory scrutiny by the Financial Conduct Authority (FCA). Responsible lending mandates stress-testing the borrower’s ability to pay interest, often at hypothetical future rates higher than current offers.
Typical Maximum LTV Limits for RIO Mortgages
The specific maximum LTV you can achieve depends entirely on the lender, your age, and your verifiable income. There is no single universal maximum, but typical market ranges are:
LTV Range Based on Lender Policy
Most mainstream and specialist UK lenders set their maximum RIO LTV within a conservative band:
50% to 55%: This is the most common range, especially for older applicants (those aged 75+) or those with complex income streams. Lenders prioritise the security of the loan over maximising the advance.
55% to 60%: Some competitive lenders may offer up to 60% LTV, usually reserved for applicants who are younger (e.g., early 60s) and possess very robust pension and income verification, demonstrating ample capacity to meet the interest payments.
Above 60%: Advances over 60% LTV are extremely rare in the RIO market and may only be offered by highly specialised lenders in niche circumstances, often tied to a significantly higher interest rate or shorter maximum loan term.
It is important to understand that having sufficient equity (the required deposit) is only half the equation. Crucially, RIO mortgages still require successful passing of a stringent affordability test, which is often the biggest hurdle.
The Crucial Role of the RIO Affordability Test
Unlike Lifetime Mortgages, where no monthly payments are required (as interest rolls up), RIO mortgages demand that you prove you can afford the interest payments every month, for the life of the mortgage. This is a core reason why the LTV is capped lower.
Lenders perform deep stress testing on your retirement income, which typically includes:
- State pension income.
- Private or occupational pension income.
- Rental income (if applicable and sustainable).
- Investment income (if sustainable and verifiable).
The affordability assessment must demonstrate that you can comfortably cover the monthly interest payments even if interest rates rise significantly in the future. Lenders look not just at your current income but also at your long-term expenditure and savings. If your verified income does not meet the lender’s stress-tested criteria, your maximum loan size—and therefore your LTV—will be reduced, regardless of how much equity you hold in the property.
If you are considering a RIO mortgage, understanding your current credit commitments and financial history is essential before applying. Knowing your credit standing allows you to proactively address any potential issues that could affect the affordability assessment and subsequent LTV offer. Get your free credit search here.

Factors That Influence Your Specific Maximum LTV Offer
While market norms exist, your final maximum LTV offer will be bespoke, influenced by several personal factors:
1. Applicant Age
Lenders often have tiered LTV limits based on age. Younger applicants (e.g., 55–65) generally have access to higher LTVs (closer to 60%) because their income is likely to remain stable for longer, and the projected loan term is extended. Conversely, applicants in their late 70s or 80s are typically restricted to lower LTVs, sometimes 50% or less, to mitigate risk.
2. Property Type and Location
Non-standard construction properties (e.g., certain steel-framed or timber-framed homes), properties above commercial premises, or those in remote locations may attract lower LTV limits than standard brick-built homes in high-demand areas. Lenders need confidence in the property’s saleability when the loan eventually needs repaying.
3. Exit Strategy
Although RIO mortgages are Interest-Only, lenders must be assured of the ultimate repayment of the capital. The standard exit strategy is the sale of the property. Lenders may require evidence that there are sufficient funds (such as other assets or life insurance policies) available to repay the loan if the borrowers enter care, or that the property value provides a significant equity cushion.
RIO Mortgages vs. Equity Release: A Compliance Note
It is crucial not to confuse RIO mortgages with traditional Equity Release products (Lifetime Mortgages). While both are designed for older homeowners, they differ fundamentally regarding payments and LTVs:
- RIO Mortgages: Require monthly interest payments. Failure to meet these payments means the loan is treated like any standard mortgage default.
Your property may be at risk if repayments are not made. Consequences of default can include legal action, repossession, increased interest rates, and additional charges.
LTVs are lower (typically up to 60%) because of the ongoing affordability requirement. - Equity Release: Requires no monthly payments; interest rolls up (compounds) over time. LTVs are typically calculated based on actuarial tables (age of borrower) and can sometimes reach 50-55% for older borrowers, but the debt grows exponentially.
Understanding the difference is key to assessing the long-term cost and risk. For further impartial advice on retirement mortgage options, consult independent resources like MoneyHelper, which provides comprehensive government-backed information on mortgages for older people.
People also asked
What happens to the RIO mortgage when the borrower dies?
When the last surviving borrower dies or moves into long-term care, the RIO mortgage term ends. The property is then typically sold by the borrower’s estate, and the proceeds are used to repay the outstanding capital loan amount to the lender. Any remaining funds go to the beneficiaries.
Is the interest rate higher on a RIO mortgage compared to a standard mortgage?
Generally, RIO mortgage interest rates may be slightly higher than the best standard residential rates, reflecting the unique risks associated with long-term lending to retirees and the specialist nature of the product. However, rates are competitive and usually significantly lower than those found on interest-roll-up Equity Release products.
Can I switch from a RIO mortgage to a Lifetime Mortgage later?
Yes, it is often possible to switch from a RIO mortgage to a Lifetime Mortgage (Equity Release), provided you meet the relevant criteria. This switch might be considered if your income circumstances change and you can no longer afford the monthly interest payments, but you must be prepared for the interest to compound rapidly once payments cease.
Can I make capital repayments on a RIO mortgage?
Most RIO mortgages allow voluntary capital repayments, often up to a specific percentage of the outstanding balance (e.g., 10%) per year, without incurring early repayment charges (ERCs). Making capital repayments helps reduce the final debt owed when the property is sold, improving the equity passed on to your estate.
Does the maximum age limit affect the LTV I can get?
While RIO mortgages do not typically have a maximum age for the *end* of the term, they do have a maximum age limit for *application* (often around 85 or 90). Crucially, the older you are at the point of application, the more conservative the lender tends to be regarding the maximum LTV they will offer, as your ability to sustain interest payments over time is a key consideration.
Summary of Maximum RIO LTV
The maximum LTV on a Retirement Interest-Only mortgage in the UK is governed by a strict assessment of long-term affordability rather than just the property value alone. While the ceiling sits around 60%, most applicants will find offers closer to 50% to 55%, ensuring a substantial safety buffer for the lender and reflecting the unique requirement for the borrower to demonstrate sustained capacity to service interest payments throughout retirement.
