Downsizing vs equity release: how do they compare financially?

Both options can release cash from your home in later life, but they work in entirely different ways and carry entirely different costs. Downsizing means selling and buying a smaller or cheaper property; you walk away debt-free but you have to move. Equity release (specifically a lifetime mortgage) means borrowing against your current home while staying in it, with interest that compounds until the property is eventually sold. Neither is a free lunch.

The decision turns on four things: how much it costs to execute each route, what the long-term debt trajectory looks like, what happens to your estate, and frankly, how much you want to stay where you are.

What does downsizing actually cost?

The phrase "release £200,000 by moving somewhere smaller" makes it sound clean. It rarely is. The buying and selling process generates friction costs that most people underestimate until the solicitor's bill arrives.

In England, here's what typically eats into the proceeds:

Estate agent fees: Usually 1% to 2% of the sale price, plus VAT. On a £450,000 sale, that is £4,500 to £9,000.

Conveyancing (both transactions): Expect £1,500 to £2,500 per transaction for a solicitor handling both the sale and purchase. Budget £3,000 to £5,000 for the pair.

Stamp duty: If your new property costs more than £125,000 (which, outside a handful of areas, it will), stamp duty applies. On a £250,000 purchase, that is £2,500 at current rates. On £350,000, it rises to £7,500. The GOV.UK stamp duty calculator is worth running before you assume the numbers work.

Removals: A local move with a reputable firm runs £1,000 to £2,000. Move further, or have a full house to shift, and £3,000 is not unusual.

Miscellaneous: Survey fees, mortgage arrangement fees if you're taking a small mortgage on the new property, and the often-forgotten costs of adapting a new home to your needs, new carpets, a stairlift if required, redecorating.

On a combined sale of £450,000 and purchase of £280,000, realistic total costs land somewhere between £15,000 and £22,000. That is not a trivial haircut on the £170,000 you thought you were releasing.

What does a lifetime mortgage actually cost over time?

A lifetime mortgage has no monthly repayments if you choose roll-up interest (and most people do). The interest compounds annually, which means the debt grows faster than most borrowers expect.

Here is a worked example. You are 68, your home is worth £400,000, and you borrow £80,000 at a fixed rate of 6.5% (rates in late 2024 have been in the 6% to 7% range for most mainstream providers).

At 6.5% compounding annually:

• After 10 years: approximately £150,000 owed
• After 15 years: approximately £204,000 owed
• After 20 years: approximately £277,000 owed

That £80,000 loan has more than tripled in 20 years. The maths does not change because you are not making payments; it just runs quietly in the background. I have seen clients genuinely surprised by this when they sat down and modelled it properly. The Equity Release Council's own guidance stresses that borrowers should take independent legal advice before proceeding, and the compounding schedule is exactly why.

The property also needs to have grown in value for the estate to retain any meaningful equity. A £400,000 home growing at 2% a year reaches roughly £594,000 after 20 years. Against a £277,000 loan, that leaves around £317,000 for the estate. Comfortable enough, but the same home growing at 1% a year reaches only £488,000, leaving £211,000. Property growth is not guaranteed, and lenders do not promise it.

How the two routes compare side by side

Does your age and health change the calculation?

It changes it substantially. Lifetime mortgage rates are partly determined by age and, where enhanced terms apply, by health status. Some providers, including More2Life and Pure Retirement, offer enhanced lifetime mortgages: if you have certain medical conditions (heart disease, diabetes, a history of stroke), you may qualify for a higher loan-to-value ratio or a lower interest rate. That can meaningfully shift the comparison with downsizing.

Age matters for the downsizing route too, in a different way. A move at 68 is logistically demanding but manageable for most. A move at 78, particularly if mobility has declined, is a far bigger undertaking. If you can see that you might struggle in a larger property in five years' time, downsizing sooner, to a well-adapted, accessible home, may serve you better than waiting. Age UK has a useful guide to practical considerations in later-life moves.

The emotional weight of leaving a long-held family home is not a financial variable, but it is real and worth naming. I would not dismiss it. Some people genuinely do not want to leave, full stop, and that can legitimately tip the decision toward equity release if the numbers are otherwise close.

What happens to the estate and inheritance?

Downsizing leaves a clean asset, usually a smaller property held outright. Your beneficiaries inherit whatever it is worth with no debt attached. Simple.

A lifetime mortgage is different. The loan, plus all the compounded interest, is repaid from the estate when the last borrower either dies or moves permanently into care. The property is sold, the lender is repaid, and what remains goes to the estate.

Some providers have added features to address this directly. Aviva and Legal & General both offer inheritance protection options that ringfence a set percentage (say, 20% or 30%) of the final sale price for the estate, regardless of the loan balance. This reduces the maximum amount you can borrow, but it gives certainty to beneficiaries. It is worth discussing with an FCA-authorised equity release adviser whether the protection rider makes sense for your situation.

One thing is firm under Equity Release Council rules: the no negative equity guarantee means the estate will never owe more than the property sells for. Even if compound interest has pushed the loan above the property's value, the lender absorbs the shortfall. That is a meaningful protection.

What about using equity release to fund the downsize itself?

A less obvious option: some people use a small equity release drawdown to fund renovation or adaptation work on their current home (a wet room, a ground-floor bedroom, a stairlift), removing the trigger for moving at all. Key Later Life Finance and others offer drawdown facilities precisely for this kind of staged use. The logic is that if the catalyst for downsizing is a home that no longer meets your needs, adapting the existing home might cost far less in compounded interest than the costs of moving.

This won't suit everyone, particularly if the current home is genuinely too large or expensive to maintain. But it is worth modelling before assuming the only options are a full move or a full lifetime mortgage.

Which costs less in the long run?

There is no universal answer, and I would be doing you a disservice to pretend otherwise. Downsizing involves fixed, upfront friction costs and no ongoing debt. A lifetime mortgage has lower upfront costs but growing debt that eventually must be settled.

A broad heuristic: if you are likely to live in the property for fewer than eight to ten years (whether due to age, health, or plans to move into care), the fixed costs of downsizing start to look steep relative to the compounded interest on a modest equity release loan. Over a longer horizon, compound interest can significantly erode the estate.

The crossover point moves depending on the interest rate, how much you borrow, and what the property does in value. No formula works for every household.

What I would say is this: both decisions deserve proper independent financial advice, not just a comparison article. The numbers are significant, the compounding is unforgiving, and the tax and benefits implications (particularly around means-tested benefits) can catch people off guard. Anyone taking out a lifetime mortgage must, by FCA rules, take regulated advice first. Downsizing carries no such requirement, but I would not make a decision of this size without professional input regardless.
