Should I Sell My Buy-to-Let or Keep It? An Honest Framework for 2026
By Kieran Ali, founder of CiK Finance · Published 20 August 2026
The short answer
Sell if you would not buy the property today with its equity as cash, or if it no longer covers its costs at the rate you will actually pay once Section 24 is applied. Keep it if it passes both tests, then check the structure it sits in. Decide before the renewal letter arrives, not because of it. The rate is the last question, not the first.
- Would you buy this rental property today, with the equity as cash?
- Does it still work at the rate you will actually pay, after Section 24?
- Does the structure you hold it in still fit?
- If you sell, can you time it around early repayment charges and the tax year?
- One in five landlords (21%) sold property in the year to spring 2026 and only 7% bought, three sellers for every buyer (National Residential Landlords Association / Pegasus Insight, June 2026). 36% told the NRLA in May 2025 they were considering a complete exit because of Section 24.
- Selling can be the right answer. So can keeping. What is rarely right is letting the renewal letter make the decision for you.
- If you own four or more mortgaged buy-to-lets, lenders assess the whole portfolio, not just the property in question. That changes the sell-or-keep sum.
"It's just not worth being a landlord anymore." A landlord wrote that in a forum thread this month, and the replies were a queue of people agreeing. The Renters' Rights Act in force since 1 May, Section 24, Making Tax Digital's first quarterly deadline this August, and fixed rates from 2021 ending into a market that looks nothing like 2021.
Some of those people should sell. Some should not. Almost none of them should decide in the week the remortgage letter arrives, which is when most of these conversations reach my desk.
So here is the framework we use, in the order we use it. It is not tax advice; the tax half belongs with your accountant. The mortgage half is the one that tends to get skipped.
Question one: would you buy this property today?
Take the equity you would walk away with if you sold. Imagine it as cash in your account this morning. Would you spend it buying that exact house, on that street, with that tenant profile, as an investment?
If yes, keep reading; the rest of the framework is about how to keep it well. If no, keeping it needs a better reason than habit, and "it seems a shame to sell" is not a financial reason. A property you would not buy today is a property you are choosing to hold every month it stays on the books.
Very few of the landlords I meet have asked this of a property they already own. It is the single most clarifying one. If the property is a former home you kept when you moved, our guide to renting out your house and buying another covers that particular version of the decision.
Question two: does it still work at the rate you will actually pay?
The buy-to-let refinancing wave is real. Fixes taken in 2021 and 2022 are ending through 2026, 2027 and 2028 into higher rates, and the industry talks about it as something coming. For any one landlord, though, the wave is a single date: the end of their own fix.
The sum to run, before that envelope arrives: take the property's rent, subtract the mortgage payment at a rate a few points higher than the one you took, then apply Section 24. On property held personally, mortgage interest is no longer deducted from rent before tax; you are taxed on the rent and get a tax credit worth 20% of the interest afterwards. For a higher-rate taxpayer that means taxable profit can be materially higher than real profit, and a rental that looks fine on the bank statement can look very different on the tax return.
If the property still clears that bar with room to spare, good. If it only clears it on the assumption that the tenant never misses a month, that is not a plan; that is a hope with a mortgage attached.
Question three: does the structure still fit?
If you are keeping more than one property, the personal-name-versus-limited-company question deserves an hour with your accountant and a parallel hour on the mortgage side, because the borrowing can look different in each.
Company applications are commonly stress-tested at around 125% rental cover against around 145% for a higher-rate taxpayer personally, which can mean the same rent supports more borrowing through a company. Against that: company products are often priced a little higher, personal guarantees are standard, and moving property you already own into a company is a sale and repurchase for tax and stamp duty purposes, often with early repayment charges on any mid-term fixes. From 6 April 2026, the incorporation relief many landlords rely on has to be actively claimed on the tax return rather than applying automatically. Your accountant will know the detail; our job is making sure the mortgages are planned in the same meeting rather than afterwards.
Our limited company buy-to-let guide works through the numbers with an example.
Question four: if you sell, sell well
Deciding to sell is also a plan, and it has its own timing.
Early repayment charges: selling mid-fix can trigger a charge worth thousands. Sometimes it is worth paying to get out; sometimes waiting four months to the end of the fix saves more than the four months cost. Check the date before you instruct an agent.
The tax year: capital gains and the timing of completion around 5 April can matter, and that is squarely one for your accountant.
The rest of the portfolio: if you own several, one sale can fund the resilience of the others. Clearing or reducing borrowing on the properties you keep, ahead of their own renewals, is a legitimate reason to let one go.
The one thing that changes at four properties
If you own four or more mortgaged buy-to-lets, lenders classify you as a portfolio landlord and assess the whole portfolio on every application: a full property schedule, a business plan, and cash-flow stress across everything you own, not just the property being financed. Plenty of people cross that line one purchase at a time without noticing.
For the sell-or-keep decision, this cuts both ways. A weak property can drag the whole portfolio's numbers on the next application, which is an argument for selling it. But some lenders are more comfortable with a well-run portfolio than with a first-time landlord, which is an argument for keeping the good ones and presenting them properly.
Sell or keep: what this looks like in practice
The conversation that tends to cross our desk: a landlord with a handful of properties, a fixed rate ending within the year, and a vague sense that the sums have got worse. We run the four questions in order. Often one property fails question one, one or two pass everything, and the answer is a sale that funds keeping the rest on better terms. Occasionally the answer is to keep everything and restructure. Occasionally it is to sell the lot, and when it is, we say so.
What we do not do is start at "what rate can I get". That is the question the letter asks. It is not the question that decides whether the property should still be yours.
Common questions
Is buy-to-let still worth it in 2026?
For some properties and some landlords, yes; for others, no. It depends on the specific property's yield after Section 24 at current rates, your tax position, and whether you would buy it today. Sector-wide, three landlords sold for every one who bought in the year to spring 2026 (NRLA, June 2026), and 36% told the NRLA in May 2025 they were considering a complete exit because of Section 24. That tells you the sums have got harder, not that they never work.
Should I sell my buy-to-let before my fixed rate ends?
Selling mid-fix usually triggers an early repayment charge, which can run to thousands. Compare that charge against what you would save or lose by waiting to the end of the fix. Sometimes paying it is right; often waiting a few months is cheaper. And waiting is not the same as drifting: many lenders let you secure a new deal or a product transfer up to six months before the end date, so the decision to keep can be made without landing on the standard variable rate. Check the exact end date and the charge schedule before you instruct an agent.
Why are landlords selling up in 2026?
Several pressures arriving at once: the Renters' Rights Act in force from 1 May 2026 (Section 21 abolished), Section 24 restricting mortgage interest relief for personally held property, Making Tax Digital's first quarterly deadline on 7 August 2026, and fixed rates from 2021 and 2022 ending into higher rates. The National Residential Landlords Association found three landlords sold for every one who bought in the year to spring 2026 (June 2026). Whether the "landlord exodus" applies to you comes down to the four questions above, not the headlines.
How much tax do I pay if I sell my buy-to-let?
Capital Gains Tax on a residential property held personally is 18% within the basic-rate band and 24% above it, after a £3,000 annual exempt amount for 2026/27, and it must be reported and paid within 60 days of completion (GOV.UK, checked August 2026). Property held in a company pays corporation tax instead. Which bracket you fall in and what you can deduct is squarely one for your accountant.
Should I move my buy-to-lets into a limited company instead of selling?
Sometimes. A company structure can improve what the rent supports under a stress test and changes the tax treatment, but moving property you already own is a sale and repurchase for stamp duty and capital gains purposes, and existing mortgages usually need replacing. Get the tax half from your accountant and the mortgage half planned alongside it, not afterwards.
Fixed rate ending within the year?
