Should I Sell My House or Rent It Out? The 2026 UK Guide

By Lisa Hayes · 19 August 2026

Sell if you need the equity, if the numbers only work on paper, or if being a landlord would be a job you never applied for. Rent it out only if you can afford the mortgage with the house empty for three months, you genuinely want to hold the asset for a decade, and you've checked what the Renters' Rights Act 2025 and Section 24 do to your return. For most homeowners in 2026, the honest answer is sell.

That's a blunt opening, and I don't offer it lightly. Ten years ago the sell-or-rent question was close. Mortgage interest was fully deductible, section 21 gave you an exit, the stamp duty surcharge was 3%, and nobody was talking about EPC deadlines. Every one of those things has moved against the small landlord, and most of the movement happened in the last eighteen months. The maths below is the maths, not an opinion.

What's actually changed for landlords in 2026?

This is the part people skip, and it's the part that decides the question.

The Renters' Rights Bill received Royal Assent on 27 October 2025, becoming the Renters' Rights Act 2025. The first and biggest phase of it commenced on 1 May 2026. From that date, in England:

• Section 21 is gone. No new section 21 notices can be served, under any circumstances. To get possession you now need a specific statutory ground and, if the tenant doesn't leave, a court.
• Assured shorthold tenancies were abolished. Every private tenancy is now an assured periodic tenancy rolling month to month. There are no fixed terms any more. Your tenant can give two months' notice and go; you cannot.
• There's a 12-month protected period. You generally can't use the "I want to sell" or "I want to move back in" grounds in the first year of a tenancy. Plan on a minimum realistic commitment of well over a year.
• You can't take more than one month's rent in advance, and rental bidding is banned. If you were counting on six months up front from an overseas tenant, that's finished.
• Tenants can request a pet and you can't unreasonably refuse.
• Existing tenancies had to be given the government's Renters' Rights Act Information Sheet 2026 by 31 May 2026.

Phase two lands later in 2026 with a Private Rented Sector database. Landlords will have to register themselves, their properties and their compliance paperwork. It won't be optional, and it won't be free.

Scotland and Wales run their own regimes — Private Residential Tenancies under the Private Housing (Tenancies) (Scotland) Act 2016, and occupation contracts under the Renting Homes (Wales) Act 2016. Both already removed no-fault eviction. Wherever you are in the UK, the direction of travel is identical: longer tenancies, more paperwork, slower exits.

Can I rent out my house on my existing mortgage?

Not without asking. Every residential mortgage contains a clause saying the property must be occupied by you. Letting it out without telling your lender is a breach of contract, and it's the kind of breach that lets them demand the whole balance back.

You have two legitimate routes.

Consent to let. Your lender gives written permission to rent the property out temporarily, usually for six to twelve months, sometimes renewable. Many lenders charge an administration fee; some load your interest rate; a few do it for nothing if you're on a fixed deal you're already paying for. It is entirely discretionary. Lenders have become noticeably more cautious since May 2026, because a periodic tenancy with no section 21 route makes their security harder to realise if you default.

Remortgage to buy-to-let. The permanent option. Expect to need around 25% equity, and to pass an interest coverage ratio test — the rent typically has to cover 125% to 145% of the mortgage interest at a stressed rate, not your actual pay rate. Higher-rate taxpayers are usually stress-tested at the harsher end. The average UK buy-to-let mortgage costs around 5.64%, though sharper three-year fixes were available from about 4.17% in mid-August 2026.

Two things people get wrong here. First, you'll usually lose the residential rate you're currently enjoying, which can add hundreds a month before you've earned a penny of rent. Second, if you're breaking a fixed deal early to remortgage, check the early repayment charge first. On a five-year fix it can be 4% or 5% of the balance.

What will I actually earn if I rent it out?

Here's the sum almost nobody does properly. Take a real example: a £280,000 three-bed with £120,000 outstanding on the mortgage, letting for £1,250 a month.

• £1,388average UK monthly private rent, June 2026
• 3.3%annual rent inflation to June 2026
• 5.64%average UK buy-to-let mortgage rate
• 5.8%average UK gross rental yield

Read that bottom row again. The higher-rate taxpayer earns £535 for a year of being a landlord, and they are sitting on roughly £160,000 of equity to do it. That's a return of 0.33%. A cash ISA beats it without ever taking a call about a broken boiler on Christmas Eve.

The basic-rate figure is better, but watch the trap: rental profit is added to your income, so £9,915 of profit can drag part of your earnings over the higher-rate threshold, at which point your effective tax rate on the last slice jumps to 40%. Plenty of "basic-rate landlords" discover in January that they weren't.

Change the inputs and the answer changes. Self-manage instead of using an agent and you claw back £2,160 — but you've bought yourself a second job. Own the house outright and the whole Section 24 problem evaporates, which is exactly why mortgage-free landlords still do well and mortgaged ones increasingly don't.

How is rental income taxed, and what is Section 24?

Rental profit is taxed as income at your marginal rate through self-assessment. What makes it punishing is Section 24 of the Finance (No. 2) Act 2015, fully in force since April 2020.

Before Section 24, mortgage interest came off your rental income as a business expense, so you were taxed on the actual profit. Now you're taxed on rent minus everything except interest, and then handed a tax credit worth 20% of the interest. A basic-rate taxpayer is roughly neutral. A higher-rate taxpayer loses half the relief they used to get. An additional-rate taxpayer loses more.

What you can still deduct: letting agent fees, landlord insurance, repairs and maintenance (not improvements), safety certificates, ground rent and service charge, accountancy, and a replacement-of-domestic-items relief for like-for-like replacements of furnishings.

What catches people out: replacing a worn-out kitchen with a comparable one is a repair; upgrading it to a better one is an improvement, and improvements don't reduce your income tax. They do reduce a future capital gain, so keep every receipt regardless. If any of this is unfamiliar territory, our property jargon guide unpicks the terminology.

Will I pay capital gains tax if I rent it out and sell later?

Probably some, yes — and this is the cost people find hardest to believe.

While a house is your only or main residence, Private Residence Relief means the gain is exempt. The moment you move out and let it, you start accruing a period of non-qualifying ownership. When you eventually sell, the gain is apportioned by time. Only the final 9 months of ownership are automatically covered regardless of occupation (36 months if you're disabled or have moved into a care home).

So if you owned the house for 12 years, lived in it for 8 and let it for 4, roughly 3 years and 3 months of the gain becomes taxable. On residential property the rates for 2026/27 are 18% for basic-rate taxpayers and 24% for higher and additional-rate taxpayers, and the annual exempt amount has been cut right back to £3,000, so it absorbs very little.

Lettings relief used to soften this. Since April 2020 it only applies where you shared occupation with your tenant, which almost never describes an accidental landlord.

One more sting in the tail: you must report and pay CGT on UK residential property within 60 days of completion, using HMRC's UK Property Account. Not at the next self-assessment deadline. Sixty days. Late filing penalties start immediately.

Sell now, while it's still your main residence, and none of this applies. That single fact is often worth more than four years of rent. If you're weighing up a property you didn't buy to live in, our guide to selling an inherited property covers a different set of rules again.

Does keeping the house stop me buying my next one?

It makes it more expensive and harder, and this is the single biggest hidden cost in the whole decision.

If you keep your current home and buy another, the new purchase is an additional dwelling. In England and Northern Ireland that means a 5% stamp duty surcharge on the entire price, on top of standard SDLT. The surcharge rose from 3% to 5% on 31 October 2024, and the nil-rate threshold dropped back to £125,000 on 1 April 2025. On a £300,000 next home, the surcharge alone is £15,000. Scotland's Additional Dwelling Supplement and Wales' higher rates of Land Transaction Tax work on the same principle.

You can reclaim the surcharge if you sell your former main residence within three years. But you have to find £15,000 in cash at completion first, and you only get it back if you sell — which rather undermines the plan to keep it.

Then there's affordability. Lenders will assess your new mortgage while you're carrying a buy-to-let. Some ignore the old mortgage if the rent covers it comfortably; many don't, and stress-test both. Accidental landlords routinely find the house they wanted has become unaffordable the moment they decided to hold on to the old one.

What about the EPC C deadline in 2030?

The Warm Homes Plan, published on 21 January 2026, confirmed that all privately rented homes in England will need to meet EPC C by October 2030. The earlier proposal to apply it to new tenancies from 2028 was dropped. The spending cap landlords are expected to meet was reduced from £15,000 to £10,000, and it's lower still where £10,000 would be 10% or more of the property's value.

The EPC methodology itself is being overhauled during 2026, moving to metrics based on how well a property retains heat rather than modelled energy use. Nobody can tell you today exactly what your 2019 EPC will look like under the new system.

If your house is a solid-wall Victorian terrace sitting at band D or E, price in a five-figure retrofit somewhere before 2030 — or accept that you'll be selling into a market where buy-to-let buyers have already discounted for it. Our guide on EPCs and selling goes into the certificate itself in more detail.

Sell or rent: the factors that actually decide it

If you've ticked mostly the left-hand column, stop reading and get the house valued. Sentiment about "keeping a foot on the ladder" has cost a lot of people a lot of money.

Six real situations, and what I'd do

Job relocation, might come back in two years. Rent, but only with consent to let and eyes open. The 12-month protected period plus notice periods means "two years" realistically becomes closer to three before you have vacant possession. If the return date is firm and short, consider selling and renting where you're going.

Moving in with a partner, keeping your flat "just in case". Sell. This is almost always emotional hedging dressed up as investment. You'll pay a 5% surcharge on the joint purchase, hand HMRC a slice of a gain that's currently exempt, and earn very little for the privilege.

Inherited a house you don't need. Different maths entirely — there's usually no mortgage, so Section 24 doesn't bite, and the base cost is reset at probate value so the gain is small. Renting can genuinely work here. But so can a clean sale, especially with siblings involved. See selling an inherited property.

The house won't sell and you're sick of it. Renting it out to "wait for a better market" is the classic mistake. You're not waiting; you're converting a liquid asset into an illiquid one with a tenant attached, then paying CGT on the way out. Fix the actual problem first — nine times out of ten it's the asking price. Read why isn't my house selling before you call a letting agent.

Emigrating. Non-resident landlord scheme, non-resident CGT (which applies even to your former main residence for the period after you leave), a UK tax return every year, and managing repairs across time zones. Most people who do this regret it by year three. Sell unless you're certain you're coming back.

Already have a tenant in place. You don't have to evict anyone to sell. Tenanted properties trade at a discount on the open market but sell readily to investors and to cash buyers. Our guide to selling a tenanted property covers how that works post-May 2026.

"I'll just rent it out for a year and see" — why that's the worst option

It's the most common plan and the weakest one. You get the downside of both choices and the upside of neither.

You pay to set up as a landlord — inventory, safety certificates, agent's tenant-find fee, possibly a mortgage product switch — and then amortise all of it over twelve months instead of ten years. You start the CGT clock. You take the property off the market at whatever the current price is, and you have no idea what the price will be when you can next access it. And under the 2026 rules, "a year" isn't a year: the protected period alone runs twelve months from the tenancy start, before notice.

If you're not committing for the long term, don't commit at all. Get a realistic figure with a free house valuation and make the decision on numbers rather than on delay.

What are the legal duties if you do go ahead?

Not exhaustive, but this is the floor. Miss these and the fines are real.

1. Lender consent in writing, before a tenant moves in.
2. Gas Safety Record (CP12) from a Gas Safe registered engineer, renewed annually, given to the tenant.
3. Electrical Installation Condition Report, renewed at least every five years.
4. Smoke alarm on every storey and a carbon monoxide alarm in any room with a fixed combustion appliance.
5. Valid EPC, currently band E or above, band C from October 2030.
6. Deposit protected in a government-approved scheme within 30 days, with prescribed information served. Get this wrong and possession claims can fail.
7. How to Rent guide and the Renters' Rights Act information sheet served correctly.
8. Right to Rent checks on every adult occupier in England.
9. Licensing — check whether your council runs selective or additional licensing. Many do, and the fees run into hundreds.
10. Landlord insurance, not standard home insurance, which will not cover you.

If you use a letting agent, check they belong to a government-approved redress scheme and hold client money protection. Both are legal requirements, and a surprising number of small agents still don't.

If you decide to sell, what's the cleanest route?

Two broad options, and the right one depends on how much certainty you're buying.

Open market with a good local agent gets you the highest headline price. It also comes with a chain, a survey, a mortgage valuation and a meaningful chance of falling through. Price it correctly from day one — the market is unforgiving of an optimistic launch, and you can check what's actually happening near you on our house prices page.

A genuine cash buyer gets you a fixed date and a fixed figure, typically in a fortnight to a month, at a discount to market value. If you're relocating for work with a start date, or unwinding a joint ownership, that certainty has a real price and it can be worth paying. The industry has plenty of good operators and some poor ones, so compare rather than accepting the first offer — start with how cash house buyers work, our review of the best house buying companies, and an honest look at what "below market value" really means.

Whichever route you take, start from an accurate number rather than a hopeful one. How much is my house worth walks through valuing properly, and selling your house fast covers the timescales realistically.

How to decide this afternoon

1. Get two rental appraisals and two sale valuations. Free, and they take an hour. Ignore any figure that isn't backed by comparable evidence.
2. Build the table above with your own numbers. Gross rent, minus agent, minus interest, minus insurance, minus 0.5% of value for repairs, minus a void month every two years.
3. Apply your actual marginal tax rate and the Section 24 credit. Be honest about whether the profit tips you into the next band.
4. Divide the net figure by your equity. That percentage is your real return. Compare it to a savings account before you compare it to anything else.
5. Add the surcharge. If you're buying next, put 5% of the new purchase price into the cost column of the "keep it" option.
6. Ask the two-year question. Could you leave this house let, without access to the equity, for two full years? If not, the decision is made.

Whatever you conclude, don't let the decision drift. An empty house costs money every month, an under-priced listing loses credibility, and a badly chosen tenancy is very hard to unwind under the 2026 rules.

If selling is looking like the answer, the sensible next step is to see what your house is genuinely worth to different types of buyer — open market and cash — before you commit to either. Compare offers with Ready Steady Sell and you'll have real numbers to weigh against the rental figures you've just worked out. No obligation, and no pressure either way.
