Take a £250,000 house let for £1,250 a month. That's a 6% yield, which sounds fine. Buy it in your own name with a 75% mortgage as a higher rate taxpayer, and it costs you about £1,290 a year to own.
Buy to let can still work in 2026. It works for fewer people than it used to, and the money comes from a different place. Below are the real numbers on that house, what changed to get us here, and a checker so you can run your own property through the same sums.
Watch: what this guide covers, in under a minute
Thirty years of buy to let, in one number
Buy to let mortgages turned thirty this autumn. Before 1996, if you wanted to buy a house to rent out, you had to find a lender who would treat it as a commercial deal. Then mortgages arrived that were based on the rent a property could earn, not just your salary. Ordinary people could become landlords, and lots of them did.
The early ones did very well. Estate agent Hamptons worked out that every £1 put into a typical buy to let in late 1996 had grown to £22.30 by 2026, counting rent and the rise in value. That's a whisker ahead of the S&P 500 (£22.05) and well over double the FTSE 100 (£8.96).
The last five years look very different. Hamptons puts buy to let returns at 41% over that time. The S&P 500 made 75% and the FTSE 100 made 73%.
| The typical landlord buyer | 1996 | 2026 |
|---|---|---|
| Average age | 37 | 51 |
| Average purchase price | £54,900 | £360,600 |
| On a repayment mortgage | 88% | 30% |
| On a fixed rate | 26% | 99% |
| Average mortgage rate | 7.76% | 4.52% |
Figures from Hamptons' thirty year buy to let analysis, reported in September 2026.
Mortgage rates were higher in 1996 and it still worked, because prices were low and then climbed for years. Today the average landlord pays more than six times as much for a property, and price growth has almost stopped. The ONS has UK average prices up just 0.9% in the year to August 2026, with London down 2.2%. Rents rose 3.8% in the year to September.
So the money in buy to let now comes mostly from the rent. If the rent doesn't work, waiting for the price to rescue you is a much bigger gamble than it was in 1996.
What has changed since the easy years
No single change made buy to let harder. It's a pile of them, each one taking a slice of the profit. Everything below is either in force now or already confirmed, and I say so where something still needs new law.
Mortgage interest is no longer fully tax deductible
A rule known as Section 24 was phased in between April 2017 and April 2020. If you own a buy to let in your own name, you can't take the mortgage interest off the rent before working out your tax any more. You get a tax reduction worth 20% of the interest instead. A basic rate taxpayer barely notices. A higher rate taxpayer can watch the whole profit vanish, as the example further down shows. Companies aren't caught by this rule, which is a big reason so many landlords now buy that way.
Stamp duty costs far more on a second property
If buying the property means you'll own more than one home, you pay an extra 5% stamp duty on top of the normal rates in England and Northern Ireland, across the whole price. On a £250,000 buy to let that comes to £15,000 in stamp duty, and you never see it again. Scotland and Wales have their own taxes with their own surcharges.
Borrowing costs more, and lenders test the rent harder
Bank Rate went up from 3.75% to 4% on 5 November 2026. Lenders also check that the rent covers the interest at a higher test rate, which caps how much you can borrow. I go through the test properly below, because it catches out a lot of first time landlords.
The Renters' Rights Act changed the rules on 1 May 2026
In England, Section 21 no fault evictions have ended, fixed term tenancies have become rolling ones, and rent can only go up once a year. A good landlord can still let a good home. You just run it differently now. There's more on what it means for you further down.
Rented homes will need an EPC rating of C by October 2030
In January 2026 the government confirmed that privately rented homes in England will need to reach EPC band C, or the new equivalent, by 1 October 2030. Spending is capped at £10,000 per property. It still needs new law, which the government aims to bring in during 2027. If you're looking at an older property rated D or below, put the likely cost in your sums from day one.
Tax on rental income goes up from April 2027
From April 2027, property income gets its own tax rates in England and Northern Ireland: 22% for basic rate, 42% for higher rate and 47% for additional rate taxpayers. That's two points above the normal rates. It was announced at the November 2025 Budget and is now law in the Finance Act 2026. The tax reduction on mortgage interest rises to 22% at the same time. Scotland and Wales have the power to set their own property rates. For most landlords the end result is a slightly bigger bill.
Selling up is taxed too
Sell a property that isn't your home and any gain above the £3,000 yearly allowance is taxed at 18% or 24%, depending on your income. You have to report it and pay within 60 days of completing the sale.
The honest numbers on a typical purchase
Here's how all of that lands on one property. It's made up, but the figures are realistic for plenty of places outside London. A £250,000 terraced house, bought with a 25% deposit on a five year fix, interest only at 5%, let for £1,250 a month. That's a gross yield of 6%, which most people would call a decent deal.
| Per year | Amount |
|---|---|
| Rent (£1,250 a month) | £15,000 |
| Letting and management fees (12% including VAT) | minus £1,800 |
| One month empty between tenants | minus £1,250 |
| Repairs and maintenance | minus £1,000 |
| Landlord insurance | minus £350 |
| Gas safety, electrical checks and other compliance | minus £250 |
| Profit before mortgage interest | £10,350 |
| Mortgage interest (£187,500 at 5%) | minus £9,375 |
| Cash left before tax | £975, about £81 a month |
Now the tax. Because of Section 24, income tax is worked out on the £10,350, before the mortgage interest comes off. You then get 20% of the £9,375 interest back as a reduction.
| Owned in your own name, 2026/27 | Basic rate taxpayer | Higher rate taxpayer |
|---|---|---|
| Tax on £10,350 | £2,070 | £4,140 |
| Less the 20% interest reduction | minus £1,875 | minus £1,875 |
| Tax to pay | £195 | £2,265 |
| What you keep after tax | £780 a year | £1,290 a year out of pocket |
The higher rate taxpayer pays £2,265 in tax on a property that made £975 before tax. They end up £1,290 a year worse off and have to top it up from their salary. From April 2027, with the 42% property rate and a 22% reduction, the gap grows a little to about £1,310. This is why so many higher rate landlords have sold up, or bought newer properties through a limited company.
Then there's what it cost to get in. The deposit is £62,500, stamp duty is £15,000, and legal, survey and mortgage fees add around £3,000. That's roughly £80,000 of your money tied up, for £780 a year after tax if you're a basic rate taxpayer. Less than 1% a year, before any rise in the value of the house.
Does that make it a bad investment? Not necessarily. Rents tend to rise over time while an interest only mortgage stays the same, and over twenty years the house should be worth more, even if it does very little for the next two. But be straight with yourself. On today's numbers, this is a long term bet on rents and prices, not an income. If you need it to pay you from year one, it probably won't.
The lender's test: will the rent even pass?
Before any of the tax matters, a lender has to agree to lend. On a buy to let mortgage the main test is the rent, not your salary.
The Prudential Regulation Authority, part of the Bank of England, expects lenders to check that the rent covers the interest at a higher rate than you'll actually pay. On fixes shorter than five years, that means allowing for rates at least 2 percentage points higher, and never testing below 5.5%. Fixes of five years or more are treated differently, so lenders set their own test, and many test those closer to the real rate.
How much cover a lender wants is up to the lender. 125% of the interest is common for basic rate taxpayers, and 145% for higher and additional rate taxpayers, because they pay more tax on the rent. Here's how it works on our five year fix, tested at 5.5%.
- Interest on £187,500 at a 5.5% test rate is £10,313 a year, or £859 a month.
- At 125% cover, the rent needs to be at least £1,074 a month.
- At 145% cover, it needs to be at least £1,246 a month.
At £1,250 a month, our higher rate buyer passes by £4. Now put the same house on a two year fix at 5%. The test rate jumps to 7%, and the rent would need to be £1,367 at 125% or £1,586 at 145%. Same house, same rent, and it fails. The buyer would need a bigger deposit, a five year fix or a lender that does things differently. It's the first thing I'd check on any property, and it's built into the checker below.
The Renters' Rights Act and the new rules for landlords
If you're thinking of letting a property in England, this is the biggest change to renting in a generation. It came in on 1 May 2026. You can still be a landlord. You just need to know how it works now.
| What changed | What it means for you |
|---|---|
| Section 21 no fault evictions have ended | To get the property back you need a legal reason, such as rent arrears, or wanting to sell or move in. |
| Selling or moving in has limits | You can't use either reason in the first 12 months of a tenancy. You must give 4 months' notice, and you can't market or re-let the property for 12 months afterwards. |
| Fixed terms are gone | Tenancies roll on month to month. Tenants can leave with 2 months' notice. |
| Rent can rise once a year | You give at least 2 months' notice. Tenants can challenge a rise at a tribunal before it starts. |
| Limits on rent in advance and bidding | Once the tenancy is agreed you can ask for no more than one month's rent upfront, and you can't accept offers above the advertised rent. |
| Pets, children and benefits | You must consider a request for a pet and can't refuse it unreasonably. You can't turn someone down just because they have children or claim benefits, though you can still check they can afford the rent. |
| Landlord database and ombudsman | The new landlord database is being rolled out area by area from late 2026. A landlord ombudsman is on the way, but there's no start date yet. |
Then there's energy efficiency. Privately rented homes in England will need to reach EPC C, or its equivalent, by 1 October 2030, with spending capped at £10,000 per property. Plenty of older terraced houses sit at D or E. Check the certificate before you make an offer, and put the cost of any work into your numbers.
Buy to let now suits people who plan to hold for years and look after their tenants. Buying, letting for a year or two and then selling empty is slower and harder under the new rules. Choose tenants carefully, keep good records, and allow for a long gap if you ever need the property back.
Check your own numbers
Put in the property you're thinking about. The checker works out the stamp duty, the cash you need, whether the rent is likely to pass a typical lender stress test, and what you'd keep each year after tax if you own it in your own name. It assumes interest only, which is how most landlords borrow.
Does it stack up?
A rough guide only, for a property owned in your own name. Tax assumes the rental profit sits entirely within your chosen band and ignores your other income, allowances and any losses brought forward. The stress test uses 5.5% or your rate if higher for five year fixes, and the higher of 5.5% or your rate plus 2 points for shorter fixes. Each lender has its own rules. Stamp duty uses England and Northern Ireland rates. Does not include capital growth or tax when you sell.
Thinking about a limited company instead? The buy to let tax calculator compares your own name against a company side by side, and my guide to buying through a limited company explains the costs most people miss.
Who buy to let can still work for
Likely to stack up
- Basic rate taxpayers, or people buying through a limited company where that suits them.
- Buyers with a large deposit, or cash, so the rent easily covers the mortgage.
- People with a ten to twenty year view who don't need the income yet.
- Properties where the rent is strong for the price, which usually means outside London and the South East.
- Landlords who run it like a business, look after the property and budget for the bad months.
Worth thinking twice
- Higher rate taxpayers buying in their own name with a big mortgage.
- Anyone counting on the rent to pay their own bills from year one.
- Buyers stretching to the smallest deposit, where one empty month or a rate rise wipes out the profit.
- Older properties with a poor EPC rating and no budget to improve them.
- Anyone hoping for a quick gain. Stamp duty alone can take years of profit to earn back.
Already a landlord by accident?
Plenty of landlords never meant to be. They moved in with a partner, or couldn't sell, so they let the old flat instead. If that's you, you've already paid the stamp duty. The real question is whether to keep it, sell it or change how it's financed.
- Start with your mortgage. Letting a property on a residential mortgage needs your lender's permission, called consent to let. It's often temporary, so a long term let usually means moving to a proper buy to let mortgage.
- Run the numbers above on your current rate. If your fixed rate ends soon, run them again at today's rates. That's where a lot of accidental landlords get a shock.
- If you're thinking of selling, work out the capital gains tax first, and remember the 60 day deadline to report and pay it.
- If you're moving and want to keep your current home to let out, my guide to let to buy explains how that works.
My honest take
I don't think buy to let is finished. People will always need homes to rent, and rents are still going up. But it has gone from something almost anyone could do on the side to a proper business, with thin margins, more rules and more tax.
If you're a basic rate taxpayer with a good deposit and a long view, and you find a property where the rent is strong for the price, it can still build wealth. If you're a higher rate taxpayer hoping for an income, the example above is not unusual, so take the sums slowly. Whoever you are, don't buy on a hunch. Run the numbers, then run them again at a higher rate with an empty month or two thrown in. If it still works after that, you've got something worth a closer look.

Buy to let in 2026 at a glance
The Short Version
- The money in buy to let now comes mostly from the rent. Price growth is a bonus, not a plan.
- Higher rate taxpayers buying in their own name can end up paying tax on a loss.
- The rent has to pass the lender's stress test before anything else matters.
- From April 2027, rental profit in England and Northern Ireland is taxed at 22%, 42% or 47%.
- Run your own numbers in the checker, then run them again at a worse rate.
General information, not tax or financial advice. The worked example is illustrative and your own figures will differ. Tax rules depend on your personal circumstances, so speak to an accountant about tax and a qualified mortgage broker about borrowing before you buy.
