What is equity release?
Equity release is a way for homeowners aged 55 and over to access the value tied up in their property without having to sell or move out. There are two main types: lifetime mortgages and home reversion plans, though lifetime mortgages account for the vast majority of plans sold in the UK today.
With a lifetime mortgage, you borrow against the value of your home and interest is added to the loan over time. You typically make no monthly repayments, although many modern plans allow voluntary payments. The full amount — original loan plus accumulated interest — is repaid when you die, move into long-term care, or sell the property.
Home reversion plans involve selling part or all of your home to a provider at below market value in exchange for a lump sum or regular payments. You retain the right to live in the property rent-free for life, but you no longer own 100% of it.
What is a retirement interest-only (RIO) mortgage?
A retirement interest-only mortgage (RIO) is a type of mortgage specifically designed for older borrowers. Unlike a standard interest-only mortgage, a RIO has no fixed end date. Instead, the capital is repaid when you die, move into long-term care, or sell the property — similar to equity release.
The key difference is that with a RIO mortgage, you must make monthly interest payments for the duration of the loan. This means lenders need to assess whether you can afford those payments from your retirement income, pension, or other sources. Because you are paying interest as you go, the debt does not grow over time.
Key differences between equity release and RIO mortgages
Monthly payments
This is the most fundamental difference. With equity release (specifically a lifetime mortgage), you are not required to make monthly payments, though many plans now offer the option to pay some or all of the interest. With a RIO mortgage, monthly interest payments are mandatory. If you cannot demonstrate sufficient retirement income to cover these payments, you will not qualify for a RIO.
How the debt changes over time
Because equity release allows interest to roll up, the amount you owe can grow significantly over the years. With a RIO mortgage, you pay the interest monthly, so the capital balance stays the same throughout the term. This is a crucial consideration for anyone concerned about preserving the value of their estate.
Affordability assessment
RIO mortgages require a full affordability assessment based on your retirement income. Lenders need to be satisfied that you can sustain the monthly payments throughout your retirement. Equity release does not require income-based affordability checks because there are no mandatory monthly payments to make.
Interest rates
RIO mortgages typically offer lower interest rates than lifetime mortgages because the lender is receiving regular interest payments and taking on less risk. Equity release rates have fallen considerably in recent years but remain higher than typical RIO rates. The difference in rates, combined with the compounding effect of rolled-up interest, means equity release is significantly more expensive over the long term.
No negative equity guarantee
All equity release plans sold through members of the Equity Release Council come with a no negative equity guarantee, meaning you will never owe more than the value of your home. RIO mortgages do not typically carry this guarantee, although in practice the loan-to-value ratios offered are conservative enough to make negative equity unlikely.
Important: Equity release requires specialist advice from a qualified adviser. Both equity release and RIO mortgages are regulated by the FCA, and you should always take professional advice before proceeding with either option.
When might equity release be better?
Equity release may be more suitable if:
- You have limited or no retirement income to cover monthly mortgage payments
- You want to access a lump sum or regular income without any ongoing repayment commitment
- You are comfortable with the debt growing over time and reducing the inheritance you leave
- You value the no negative equity guarantee for peace of mind
- You want maximum flexibility — many lifetime mortgages allow drawdown facilities where you take money as and when you need it
When might a RIO mortgage be better?
A RIO mortgage may be more suitable if:
- You have sufficient pension or retirement income to comfortably cover monthly interest payments
- You want to keep the amount you owe fixed and avoid compound interest building up
- You are concerned about preserving as much of your estate as possible for your family
- You want access to typically lower interest rates than equity release offers
- You are coming off an existing interest-only mortgage and need a solution that does not require capital repayment at a set date
How much can you borrow with each option?
The amount you can borrow depends on your age, property value, health, and (for RIO mortgages) your income. As a general guide:
- Equity release: You can typically release between 20% and 60% of your property value, with the percentage increasing as you get older. Enhanced plans for those with health conditions can offer even more.
- RIO mortgage: Loan-to-value ratios tend to be more conservative, often capped at around 50% to 60% of property value, depending on the lender and your age.
Impact on inheritance and your estate
This is one of the most important considerations for many people. With a lifetime mortgage where interest rolls up, the debt can grow substantially. On a loan of £100,000 at 5% interest with no repayments, you would owe approximately £163,000 after 10 years and £265,000 after 20 years. That growth directly reduces what your beneficiaries inherit.
With a RIO mortgage, the capital stays the same because you are paying the interest monthly. If you borrow £100,000, you still owe £100,000 in 10 or 20 years. This preserves a much larger portion of your estate for your family.
Watch out: Even with voluntary partial repayment options on equity release, the compound interest effect can still significantly reduce the value of your estate. Always model the numbers carefully with your adviser.
Can you switch between the two?
It is sometimes possible to switch from equity release to a RIO mortgage or vice versa, but it depends on your circumstances and the terms of your existing plan. There may be early repayment charges on equity release plans, particularly in the early years. Moving from a RIO to equity release may be more straightforward if your income situation changes and you can no longer afford the monthly payments.
Switching always requires fresh advice, a new application, and a new property valuation. An experienced equity release adviser can assess whether switching makes financial sense in your situation.
How to decide which option is right for you
The right choice depends on your personal circumstances, particularly your income, your attitude to debt growth, and how important leaving an inheritance is to you. Here are the key questions to ask:
- Can I comfortably afford monthly interest payments from my retirement income?
- How concerned am I about the debt growing over time?
- How important is it to me to leave a specific inheritance for my family?
- Do I need a lump sum, regular income, or a drawdown facility?
- Am I coming off an existing mortgage that needs replacing?
Speaking with a specialist equity release adviser who also understands the RIO market is the best way to compare both options properly. Nesto can match you with an experienced, FCA-regulated adviser who can assess both routes — completely free with no obligation.
