£100,000 borrowed through a lifetime mortgage at a typical rate, with no repayments made, grows to roughly £190,000 after 10 years, £361,000 after 20 years, and £686,000 after 30 – purely through compound interest. The UK equity release market grew 11% in 2025 to £2.57 billion in total lending, reflecting how mainstream this has become as a retirement planning tool. But it’s genuinely just one of three realistic routes to accessing property wealth later in life, and understanding all three properly matters more than the headline rate on any single one.
Why Comparing Headline Rates Alone Is Genuinely Misleading
A lifetime mortgage’s rate applies to a balance that grows over time as unpaid interest compounds; a Retirement Interest-Only mortgage’s rate applies to a balance that stays flat, since you’re paying the interest as you go. Comparing the two purely on their headline percentage rate, without understanding this structural difference, genuinely misses the point entirely.
Option One: Retirement Interest-Only (RIO)
Our Retirement and Later Life Mortgages page covers this route in full detail – you pay only the interest each month from your retirement income, and the capital stays exactly where it started until you die, move into care, or sell. This preserves considerably more of your property’s value for your estate than a lifetime mortgage, provided you can genuinely afford the ongoing monthly payments.
Option Two: Downsizing
Our Home Mover Mortgages page covers the mechanics of moving to a smaller, less expensive property, releasing equity as cash without borrowing anything at all. Downsizing typically releases £100,000-£300,000 in a single transaction, though transaction costs – estate agent fees, solicitor costs, Stamp Duty, and removal expenses – commonly run £15,000-£25,000, or roughly 3-8% of the new property’s price. It’s worth understanding this genuinely depends on suitable smaller properties actually being available in your area at the right price, which isn’t always the case.
Option Three: Equity Release (Lifetime Mortgage)
Our Equity Release and Lifetime Mortgages page covers this route – no monthly payments required at all, with the loan plus compounding interest repaid when you die or move into long-term care. This is genuinely the most expensive route over a typical retirement timeframe, given how dramatically compound interest grows an unpaid balance, but it remains the only option that requires no ongoing income to service at all.
A Genuine Decision Framework Worth Using
If you can comfortably afford monthly payments and expect to clear the debt within a reasonable term, a standard mortgage or RIO is typically the cheapest route. If suitable smaller properties are genuinely available and you’re willing to move, downsizing avoids borrowing and compounding interest entirely. If no mainstream lender will lend, you can’t afford even RIO-level interest payments, and downsizing isn’t realistic, equity release becomes the genuine last-resort path – worth treating it as exactly that in your own decision-making, not the default first option.
Why a Joint Mortgage Can Become a Genuine Problem After Bereavement
It’s worth understanding a scenario that catches more people out than you’d expect: if a joint mortgage loses one borrower through death, the lender will reassess affordability against the surviving partner’s income alone, and may refuse to extend the term beyond a certain age – sometimes leaving a surviving partner with just a few years to clear a meaningful balance on a genuinely limited income. This is exactly the kind of situation where understanding all three options covered here, well before it becomes urgent, makes a real difference.
Why Downsizing Protection Is Worth Knowing About
If you’ve already taken out a lifetime mortgage and held it for at least three years, and your circumstances genuinely change, “Downsizing Protection” built into many plans can allow you to repay the loan without penalty if you move to a property the new lender won’t accept for the existing plan. Worth checking whether your specific plan includes this before assuming you’re locked in indefinitely.
Alternatives Worth Ruling Out First
Before committing to any of the three main routes, it’s worth checking whether you’re claiming everything you’re entitled to – an estimated £2.2 billion in Pension Credit goes unclaimed in the UK each year, and a successful claim can unlock Council Tax Reduction, Housing Benefit, and other support worth more annually than equity release would ever release for many households. It’s also worth considering your pension’s 25% tax-free lump sum, available from age 55 (57 from April 2028), before turning to your property at all.
Raising a Smaller Sum Without Any of the Above
If your actual need is a smaller, specific sum rather than a major later-life restructuring, our Secured Loans (Second Charge Mortgages) page covers borrowing against your property without disturbing your existing mortgage arrangement at all – worth comparing against the three main routes above if your genuine need is more modest.
If Full Ownership Isn’t Necessary
Our Shared Ownership Mortgages page covers a genuinely different structure worth considering if downsizing into a smaller share of a property, rather than full ownership outright, would work better for your circumstances and remaining budget.
A Genuinely Important 2026 Development
It’s worth knowing the FCA launched its Later Life Lending Market Study in the first quarter of 2026, aimed specifically at modernising the mortgage framework for an ageing population. This is genuinely an active area of regulatory attention right now, worth watching for further changes that could affect all three routes covered here over the coming months.
Why Regulated Advice Is Required, Not Optional, for Equity Release
Before recommending equity release specifically, a regulated adviser is required to consider the alternatives covered on this page – downsizing, a RIO mortgage, a standard mortgage if you have provable income, and unclaimed benefits – rather than presenting equity release as the only option. It’s worth insisting on this proper comparison from any adviser you speak to, and using only Equity Release Council members for genuine consumer protection standards.
Getting the Right Comparison for Your Circumstances
Given how differently these three routes affect your monthly finances, your estate, and your flexibility to move again later, it’s worth having a proper conversation comparing all three against your specific circumstances before committing to any single path.

Frequently Asked Questions
Which is genuinely cheapest: RIO, downsizing, or equity release?
Downsizing avoids borrowing entirely; RIO is typically the cheapest borrowing route if you can afford the monthly payments; equity release is generally the most expensive over time due to compound interest.
Do I have to be retired to get a RIO mortgage?
No – many lenders accept working borrowers from age 50 or 55 upward, provided the monthly interest payments are demonstrably affordable.
What happens to my equity release balance over time?
It typically grows through compound interest – a £100,000 loan can grow to around £686,000 after 30 years with no repayments made, illustratively.
Is equity release always the wrong choice?
No – it’s genuinely the right route for some people, particularly where no other option is realistically available, but it’s worth treating it as one option among several, not the automatic default.
What should I check before considering any of these routes?
Whether you’re claiming all benefits you’re entitled to, including Pension Credit, and whether your pension’s tax-free lump sum could meet your need without touching your property at all.
