Should landlords sell up and cash in their gains?

Should landlords sell up and cash in their gains? For a property that earns little, selling can make sense, as for landlords, capital gains tax is charged at no more than 24%, so they keep at least 76p of every pound of taxable gain.

Experts have told Newspage that capital gains tax is "a horrible reason to sell a good property, but an even worse reason to keep a bad one", and warned that many landlords are suffering from "tax-bill paralysis".

Many landlords are sitting on large property gains but are reluctant to sell because of capital gains tax, even when the property earns them little or nothing.

Holding on is also set to cost more. From April 2027, income tax on rental profits in England, Wales and Northern Ireland will rise to 24%, 44% and 49% at the basic, higher and additional rates.

Experts said landlords should judge each property on the cash a sale would release after borrowing, tax and selling costs, and ask whether that money could work harder elsewhere.

Is now a good time for landlords to sell?

Landlords who own residential property in their own name receive tax relief on mortgage interest only as a basic rate tax reduction, currently 20%.

Mark Alexander, Founder at Norwich-based Property118.com, said: "A property bought years ago may now contain a substantial capital gain. Getting to that point involved risk, work and responsibility. Yet the prospect of paying Capital Gains Tax can make an owner reluctant even to investigate what a sale would release.

"What concerns me is how easily an estimated tax bill can become a decision never to enjoy the money.

"A carefully chosen sale could reduce borrowing elsewhere, provide a reserve for future expenditure, help your children or give you more freedom in retirement. You might retain the properties that still provide worthwhile income and suit the level of involvement you want."

Joseph Lane, CEO at Newport-based Mortgage Lane, said now is a good time to review a portfolio property by property.

He added: "My view is that landlords should hold properties that justify the money and work involved, and consider selling those that don't. If a property has risen in value but earns little, ask whether the money released after tax and selling costs would work harder elsewhere.

"Capital gains tax puts many landlords off, but letting the tax bill dictate the whole decision can be expensive. I'd start with properties producing the weakest returns after mortgage costs, tax, maintenance and empty periods, or needing repairs that won't add rent or value.

"Refinancing is worth exploring where a property is still sound, though a lower payment won't solve a profitability problem. Incorporation suits some landlords, but moving a portfolio into a company can trigger tax and refinancing costs.

"Landlords don't have to choose between keeping everything and leaving the sector. Selling the weakest property and paying down debt can work better."

Should capital gains tax put landlords off selling?

A landlord's gain is usually the difference between what they paid for the property and what they sold it for, less the costs of buying, selling or improving it. This can include estate agents' and solicitors' fees and extension work. 

David Stirling, Independent Financial Adviser at Belfast-based Mint Wealth, said: "Capital gains tax is a horrible reason to sell a good property, but an even worse reason to keep a bad one. Some landlords would apparently rather earn £200 a month for the next 20 years than give HMRC a slice of a gain they've already made.

"With residential CGT generally at 18% or 24% and the annual exemption just £3,000, the bill can undoubtedly be chunky. However landlords should stop staring at the tax bill and start looking at the net cash released.

"If £200,000 of equity is producing a tiny return, the relevant question is what that £200,000 could be doing somewhere else. Sometimes paying tax is simply the cost of making a profit."

Tony Redondo, Founder at Newquay-based Cosmos Currency Exchange, said: "Landlords should judge their portfolio on net return on trapped equity, not what they paid years ago. With property income tax heading to 44% and 49% from April 2027, holding low-yielding, personally owned properties makes little sense if net returns fall below risk-free savings rates.

"Plenty of landlords suffer 'tax-bill paralysis' over a 24% CGT bill, yet paying a one-off tax to release 76% of your gain beats trapping capital in underperformers. Sell high-equity, low-yielding personal homes first, then anything needing costly EPC upgrades or facing steep refinancing hikes.

"The alternatives: pay down debt on stronger assets, transfer to a spouse, or incorporate. Be warned. Moving existing properties triggers heavy CGT and Stamp Duty unless strict reliefs apply.

"Increasingly, landlords are cashing out and rebuilding in friendlier overseas jurisdictions, helped by Sterling hitting its best level against the Euro since March 2025 and a seven-week high against the dollar."

Which properties should landlords sell first?

For landlords, repaying the mortgage from the sale proceeds leaves the taxable gain unchanged. A property that has been heavily borrowed against can therefore carry a large tax bill while releasing little cash.

Harvey Dhillon, Founder & CEO at Zmartly, said landlords should sell the lets that earn them little and “hold on to the ones that pay their way, one property at a time”.

He added: "Keeping a poor let only because of the capital gains tax bill is the wrong call. Sell first the weak lets that free the most cash for the least tax, because the tax is on the gain, not the cash you take away, and clearing the mortgage doesn't reduce it. So a let you've borrowed heavily against can have a big gain but little equity, and the tax may eat much of the cash.

"Refinancing isn't a sale, so there's no tax on the gain yet, but if you own the let yourself, the interest only gets tax relief at the basic rate, currently 20 per cent, and can get none if the money buys something private, like a home.

"Moving lets into your own company counts as a sale at market value, and the relief that delays the tax needs a real business and, since April, has to be claimed. Don't let one tax bill make the decision for you."

Tony Sanchez, Founder at Bridging Loan Directory, said: "A property can have risen substantially in value and still contribute very little to a landlord's income. The useful question is what that equity is doing for them today and whether keeping the property still fits their plans.

"Refinancing can release money for improvements or another investment, but it also adds borrowing costs. It makes most sense when there is a clear purpose for the funds and the rental income supports the new debt.

"For landlords considering a sale, the amount left after repaying borrowing, tax and selling costs is more useful than the headline gain. That gives them something concrete to compare with the income and expenditure involved in keeping it."

What are the alternatives to selling a buy-to-let?

Moving personally owned properties into a limited company still counts as a sale at market value, so capital gains tax can be due on any gain made since the property was bought.

Nouran Moustafa, Practice Principal & IFA at Roxton Wealth, said: "I wouldn't rush to sell a property simply because its rental returns have become disappointing. Sometimes the problem isn't the property. It's the strategy. A landlord sitting on substantial capital gains should ask whether that property could work harder before accepting a potentially significant tax bill.

"For example, could a poorly performing single-let property be converted into an HMO? Subject to location, demand, planning, licensing and conversion costs, that could materially improve rental income.

"Alternatively, refinancing might release capital for another investment without selling, although additional borrowing brings costs and risks. I'd review the weakest-performing properties first, looking at net returns, maintenance costs and future potential.

"Incorporation isn't automatically a tax-saving shortcut either. Transferring properties can trigger tax liabilities."

Should landlords cash out of buy-to-let altogether?

House prices have stalled, with the average UK property price rising just 0.9% to £273,000 in the year to August 2026.

Riz Malik, Independent Financial Adviser at Southend-on-Sea-based R3 Wealth, said that for many landlords selling could make sense, but “they will be trying to sell into a depressed market where the buyers hold the cards”.

He added: "The question is will they accept the market price or are they holding out for some mythical price they have in their heads?"

Scott Gallacher, Director at Leicester-based Rowley Turton, said: "We've been saying this since 2023, when we ran a webinar asking whether it was time for buy-to-let landlords to cash out. If anything, events since then have confirmed we were right.

"Many landlords have done incredibly well, but today is a different market. Stagnant house prices, higher interest rates, increased regulation and taxes make for a toxic combination. For many, the numbers no longer make sense.

"Asset-rich, cash-poor is the real story. We're seeing people with £1m or more tied up in property, rental yields of perhaps 4% before expenses and income tax, yet little cash to enjoy their retirement. And they're still dealing with broken toilets and troublesome tenants!

"Worse still, some are so focused on avoiding capital gains tax that they're overlooking a potentially much larger inheritance tax bill when they die.

"Too many landlords aren't enjoying the wealth they've created. What's the point of being a property millionaire if you can't afford to enjoy your retirement?"
