Should I Sell My House or Rent It Out?

Should you sell your house or rent it out? Sell if you need the capital, can't absorb a few months of voids and repairs, or would be a reluctant landlord. Rent if you have a low-rate mortgage, real equity you can afford to leave tied up, a tenant-ready property and the stomach for the paperwork. For most owners in 2026, higher landlord taxes, the Renters' Rights Act and the 5% stamp duty surcharge tip the maths towards selling unless the net yield, after tax and costs, clearly beats what you'd earn on the sale money.

The honest starting point: what are you actually trying to achieve?

People ask "sell or rent?" as if there were a correct answer sitting in a spreadsheet. There isn't, because the two options solve different problems. Selling turns a house into cash and ends your involvement. Letting keeps the asset, gives you income and exposure to future price growth, and makes you a landlord with everything that implies.

So before any numbers, be blunt with yourself about the goal. Are you moving and need the deposit? Are you inheriting a house you never wanted? Have you moved in with a partner and can't bear to let the old place go? Is this a pension plan, or a way of postponing a decision? I've watched all of these play out, and the people who regret their choice are rarely the ones who miscalculated yield. They're the ones who let because selling felt like a loss, then discovered they'd bought themselves a second job.

At Ready Steady Sell, founded by Lisa Hayes, we see both ends of this. Plenty of sellers come to us after a spell as accidental landlords, tired of a tenant who stopped paying or a boiler that died in January. We also hear from people who sold in a hurry and wish they'd held on. The aim of this guide is to get you to a decision you won't resent, not to push you towards a sale.

The case for selling

Selling wins when certainty, simplicity or cash are worth more to you than potential upside.

You need the money

If you're buying elsewhere, a let property is awkward. A residential mortgage lender will usually want to know about the old house, and many will not lend against a purchase if you're keeping it without consent to let or a buy-to-let mortgage in place. Tying £150,000 of equity up in a property earning a thin net return while you stretch to afford the next home is rarely clever.

You'd rather not be a landlord

Landlords in England now work under a long and growing list of obligations: gas safety certificates, electrical installation condition reports every five years, EPC, smoke and carbon monoxide alarms, deposit protection, Right to Rent checks, and under the Renters' Rights Act 2025 a rebuilt tenancy system. Miss one and you can lose the ability to regain possession easily or face financial penalties. If reading that list makes your shoulders drop, trust the reaction.

The yield doesn't justify the risk

A house worth £250,000 that rents at £1,100 a month looks like a 5.3% gross yield. That's before anything goes wrong. We'll do the real arithmetic below, but the typical outcome is a net return that is barely above what you could earn from a decent savings account or a cash ISA with none of the hassle, and you'd carry the risk of the property market on top.

The property is awkward to let

Short leases under 80 years, non-standard construction, a flat in a block with an unresolved cladding issue, a house needing serious work: all of these make letting harder and lenders warier. If it's hard to rent and hard to sell, that's a signal to take the exit while you have options.

The case for letting

Letting makes sense in a narrower set of circumstances than the property forums suggest, but they do exist.

You have a cheap mortgage you'd lose

If you fixed at 2% in 2021 and the balance is modest, selling means repaying a cheap loan and, quite possibly, borrowing at today's rates for the next home. Letting the old property on a consent-to-let basis, or switching to a buy-to-let product, can keep that leverage working. Check the terms: consent to let is normally granted for 12 to 24 months and may come with a rate uplift.

You expect to come back

Posted abroad for two years? Renting while you travel? A short, defined absence is the best use case for letting. A vague "we might move back one day" is not.

You have a cash buffer and a low-tax position

A basic-rate taxpayer with no mortgage on the property, who can fund a roof repair out of savings, gets the most from letting. If the property is mortgage-free, Section 24 matters far less because there's no interest to disallow.

You genuinely believe in long-term growth

UK house prices have risen over the long run, but not in a straight line, and anyone claiming to know the next five years is guessing. Treat future capital growth as a bonus rather than the basis of your decision.

Run the numbers: a worked example

Here's a realistic case. You own a three-bed semi worth £250,000 with a £120,000 interest-only buy-to-let mortgage at 5.5%, rented for £1,100 a month. You pay higher-rate tax.

That is a loss, in cash terms, on a house that looks like it yields over 5%. A basic-rate taxpayer in the same position would be better off, because tax would be £1,706 less the credit, leaving a small profit, but still nothing that justifies the effort. Note that Section 24 restricts relief on mortgage interest to a 20% tax credit, which hurts higher-rate landlords most. Your own figures will differ, so use the numbers as a template, not a forecast.

Now compare with selling. Assume the same £250,000 house, £130,000 original value when you bought it and you lived in it for 5 of the 10 years of ownership. After agent fees and legal costs of roughly £5,000, you clear the mortgage and keep about £125,000. Put that into a cash savings account at 4%, and it earns £5,000 a year, taxable only above your Personal Savings Allowance (£500 for higher-rate taxpayers) or tax-free if you use an ISA. The comparison is stark: £5,000 low-effort income against minus £162 of letting income plus the hassle. The letting case rests entirely on capital growth. If prices rise 3% a year, that adds £7,500, which changes the picture, but it comes with risk and with Capital Gains Tax at the end.

The tax side, in plain English

Income tax on rent

Rental profit is taxed as income at 20%, 40% or 45% depending on your total income. You can deduct running costs, but not mortgage interest, which is where Section 24 bites: you get a basic-rate (20%) credit instead. If your rent is under the £1,000 property allowance you may not need to declare it at all, but most landlords exceed that quickly. You'll file a Self Assessment return, so register with HMRC by 5 October following the end of the tax year in which you first let.

Capital Gains Tax when you eventually sell

For disposals of residential property, CGT is 18% for the part of the gain falling within the basic-rate band and 24% above it. The annual exempt amount is £3,000. You must report and pay within 60 days of completion using HMRC's residential property return, which catches many people out. Our capital gains tax calculator will give you a first estimate.

Private residence relief is the important bit. If the property was your main home, you're exempt for the period you lived there plus the final nine months of ownership, regardless of whether you were living there at the end. The old lettings relief now applies only where the owner shares occupation with the tenant, so don't count on it. Take the earlier example: you owned for 10 years, lived there 5, then let for 5. Exempt periods are the 5 years you lived there plus the last 9 months, so about 5.75 years out of 10. The taxable fraction is 4.25/10 of the gain. If the total gain is £120,000, the taxable part is £51,000, less £3,000 allowance, leaving £48,000 taxed at 24% if you're a higher-rate payer: about £11,520. That is a real cost and it grows the longer you let.

Stamp duty if you're buying elsewhere

If you keep this property and buy another, the replacement purchase carries the higher rates for additional dwellings, a 5% surcharge on top of standard stamp duty since 31 October 2024. On a £350,000 purchase that is a very large bill. Selling the old home first usually avoids it. See our stamp duty calculator to check the numbers.

Tax rules and thresholds change in Budgets, so check GOV.UK or an accountant before acting on any figure here.

Check the practicalities before you decide to let

Mortgage permission

Never let a property without your lender's written consent. Letting without it can breach your mortgage terms, and in the worst case the lender may demand repayment of the loan. Ask whether they'll grant consent to let or require you to switch to a buy-to-let mortgage, and what it will cost.

Leasehold restrictions

If you own a flat, read the lease. Some forbid subletting or require the freeholder's consent and a fee. Short-term lets are commonly prohibited.

Licensing

Many councils operate selective licensing schemes where every privately rented home in a designated area needs a licence, with fees of several hundred pounds and conditions to meet. Check your council's website before you advertise. Operating without a required licence can lead to a civil penalty of up to £30,000 or a rent repayment order.

The Renters' Rights Act 2025

This is the big change. The Act ends assured shorthold tenancies and Section 21 "no fault" evictions in England, moving tenants onto periodic tenancies with possession only on defined grounds. Landlords can still recover a property to sell it or move back in, using specific grounds with notice periods and, for sale, restrictions on using the ground in the first months of a tenancy. Rent increases are limited to once a year through a formal route, and bidding wars above the advertised rent are banned. Read the government's guidance on GOV.UK for the current commencement dates and the detail, because the practical effect is that a bad tenant is harder to move on and a decision to sell later will take longer if the house is occupied.

That last point matters for this decision. If you let now and sell in three years, you may be selling with a sitting tenant, which limits your buyers to investors and normally reduces the price. Our guide on selling a tenanted property explains how much it can cost you.

Comparing the options side by side

Who selling suits

• Anyone buying their next home who needs the equity as a deposit.
• Higher-rate taxpayers with an outstanding mortgage on the property.
• Inherited properties in poor condition or a long way from where you live. See selling an inherited property.
• Owners of leasehold flats with rising service charges or short leases.
• Anyone who wants a clean break after separation or bereavement.

Who selling does NOT suit

• Someone with a very low-rate mortgage, plenty of equity and a short, defined time away.
• A basic-rate taxpayer with a mortgage-free property in strong rental demand, who can cover repairs from savings.
• Anyone for whom a sale would trigger a large CGT bill that can be cut by waiting or by gifting to a spouse first. Take advice before deciding.

Middle paths worth knowing about

Let short-term, then decide. A 12-month let on consent to let gives you breathing space while the market or your plans become clearer, but under the new regime you can't guarantee getting the property back on a fixed date, so only do this if you are comfortable with that.

Sell to a landlord or investor. Specialist buyers purchase tenanted property. You'll typically take a discount, but you avoid the void period and the effort of getting the tenant out.

Sell part of it. Co-ownership and shared equity buyouts exist, but they are specialist and often poor value. Read our guides before you commit.

If you decide to sell: open market or a cash buyer?

On the open market, expect 16 to 24 weeks from listing to completion, and roughly one sale in four falling through. A cash buyer can complete in 7 to 28 days, with no chain, but will pay below market value for the privilege. The industry norm is 75% to 85% of open market value. An offer above about 82% deserves scrutiny, because it either signals a very good property or a figure that will be reduced later. Use our cash offer calculator and fair offer checker to sense-check what you're given.

When a quick sale does and doesn't make sense is covered in our guide to selling a house fast. For tenanted homes in particular, cash house buyers are often the only way to complete without waiting for vacant possession, though the price reflects that.

Whoever you deal with, check membership of The Property Ombudsman (TPO) or the National Association of Property Buyers (NAPB), insist on proof of funds, and never pay upfront fees. Our comparison of house buying companies shows how the main firms perform, and Ready Steady Sell can arrange offers from vetted buyers at no cost to you.

A decision framework you can use tonight

1. Write down your reason. One sentence. If it's "I don't want to decide", sell or let for a short fixed period but set a date.
2. Get a realistic valuation. Start with our house value tool and get two agent opinions.
3. Get a realistic rent figure. Look at what comparable homes are actually achieving, not asking.
4. Build the table. Use your real mortgage rate, your real tax band and a void allowance of at least four weeks a year.
5. Price the exit. Estimate CGT for selling now and for selling in five years.
6. Stress test. What if the boiler fails, the rent drops 10% and it sits empty for three months? Can you carry that?
7. Decide. If the net return after tax doesn't beat your best low-risk alternative by a clear margin, sell.

Frequently asked questions

Is it better to sell or rent out a house in 2026?

For most owners with a mortgage, a higher tax band and no strong reason to keep the property, selling is the stronger choice. Letting works best for mortgage-free or low-mortgage owners in a lower tax band who can handle compliance and repairs.

Do I pay Capital Gains Tax if I rent out my main home first?

You may. Private residence relief covers the years you lived there and the last nine months of ownership, so the period it was let is taxable in proportion. Lettings relief is now restricted to owners who share the home with the tenant.

Can I rent out my house if I still have a residential mortgage?

Only with your lender's written consent to let, or after switching to a buy-to-let mortgage. Letting without permission can breach your mortgage conditions.

How long does it take to sell if I choose a quick sale?

A cash buyer can complete in 7 to 28 days if the paperwork is in order. The open market typically takes 16 to 24 weeks.

Can I sell a house that has tenants in it?

Yes, to investors with the tenancy in place, or to any buyer once the tenant leaves. Under the Renters' Rights Act you need a valid possession ground to recover the property, so plan early. See our guide to selling with tenants.

Will I regret selling?

Some do, mostly when prices rise sharply after a sale. Most owners who sell for a clear reason, such as clearing debt or buying their next home, are glad of the simplicity. Make the decision on the numbers and your goals rather than on fear of missing out.

The bottom line

If you can't explain, in two sentences, why keeping the house will leave you better off after tax, repairs and stress, sell it. If you can, and you've modelled it honestly, let it with the right paperwork and a good agent. Either way, get proper tax advice before you act, because the CGT rules, Section 24 and the Renters' Rights Act timetable all affect the arithmetic. This guide is general information, not financial, tax or legal advice, and every figure is illustrative.
