Buy to let can still work in 2026, but it works for fewer people than it used to, and for different reasons. The days of buying almost anything, letting it out and watching the value double are gone. Today it only makes sense when the rent covers the mortgage with room to spare, you can afford the tax, and you are in it for the long haul. Run it like a small business and it can still earn its keep. Treat it like a savings account and it probably won't.
This month marks thirty years since buy to let mortgages were launched. I was broking mortgages back then, and I have watched the whole story play out, from the boom to where we are now. So rather than tell you it is brilliant or finished, I want to show you the actual numbers on a typical purchase today, and let you run your own.
Watch: what this guide covers, in under a minute
Thirty years of buy to let, in one number
Before buy to let arrived, if you wanted to buy a house to rent out, you had to find a lender willing to treat it as a commercial deal or bend a residential mortgage to fit. Then in 1996 the Association of Residential Letting Agents teamed up with lenders including Paragon, and for the first time a mortgage was built around the rent a property could earn, rather than just your salary. That one change opened the door to hundreds of thousands of ordinary landlords.
It paid off handsomely for the people who went early. Estate agent Hamptons worked out that every £1 put into a typical buy to let in late 1996 has turned into £22.30 by 2026, once you add up rent and the rise in value. That is slightly ahead of the S&P 500 over the same period, and more than double the FTSE 100.
Here is the detail most headlines skip. Over the last five years, the same analysis puts buy to let returns at 41%, well behind global shares. And the gap between then and now is striking.
| 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, September 2026.
Rates were higher in 1996, yet it still worked, because prices were far lower and then rose strongly for years. Today the purchase price is more than six times higher, and house price growth has slowed right down. The ONS puts UK average prices up just 1.4% in the year to July 2026, with London prices actually falling. Rents, meanwhile, rose 3.8% over the year to August. In other words, the money in buy to let now comes mostly from the rent, not from the property going up in value. That changes how you should judge a deal.
What has changed since the easy years
It is not one thing that has made buy to let harder. It is a stack of changes, each one chipping away at the profit. These are the ones that matter most, and all of them are either in force now or already announced.
Mortgage interest is no longer fully tax deductible
Between April 2017 and April 2020, the rules known as Section 24 were phased in. If you own a buy to let in your own name, you can no longer deduct mortgage interest from your rent before working out your tax. You get a tax credit worth 20% of the interest instead. For a basic rate taxpayer that makes little difference. For a higher rate taxpayer it can wipe out the profit entirely, as the example further down shows.
Stamp duty costs far more on a second property
If buying the property means you will own more than one home, you pay an extra 5% stamp duty in England and Northern Ireland on top of the normal rates, across the whole price. On a £250,000 buy to let that is £15,000 in stamp duty, money you never get back. Scotland and Wales have their own versions with different rates.
Borrowing costs more, and lenders test the rent harder
Bank Rate is 3.75% and was held there in September 2026. Lenders also check that the rent comfortably covers the interest at a higher test rate, which limits how much you can borrow. I explain the test properly below, because it catches a lot of first time landlords out.
The Renters' Rights Act changed the rules on 1 May 2026
In England, Section 21 no fault evictions have ended, fixed term tenancies have been replaced by rolling ones, and rent can only go up once a year. None of this stops a good landlord letting a good home, but it changes how you run one. I go through what it means for you further down.
Rented homes will need an EPC rating of C by October 2030
The government's Warm Homes Plan, published in January 2026, set 1 October 2030 as the deadline for privately rented homes in England to reach EPC band C, with spending capped at £10,000 per property. If you are looking at an older property rated D or below, build that cost into your sums from day one.
Tax on rental income goes up from April 2027
At the November 2025 Budget the government announced separate tax rates for property income from April 2027: 22% for basic rate, 42% for higher rate and 47% for additional rate taxpayers. The mortgage interest tax credit rises to 22% at the same time. For most landlords the net effect is a slightly bigger tax bill.
Selling up is taxed too
When you sell a property that is not your home, any gain above the £3,000 annual 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
Let me put all of that together on one example. It is a made up property, 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 fixed, interest only mortgage at 5%, let for £1,250 a month. That is 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, and you then get 20% of the £9,375 interest back as a credit.
| 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 credit | 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 in this example pays £2,265 in tax on a property that only made £975. They end up £1,290 a year worse off, and have to top it up from their salary. From April 2027, with the new 42% property rate and a 22% credit, that shortfall grows slightly to around £1,310. This is exactly why so many higher rate landlords have either sold, or moved new purchases into a limited company.
And don't forget what it cost to get in. The deposit is £62,500, stamp duty is £15,000 and legal, survey and mortgage fees add a few thousand more. That is around £80,000 of your money tied up, for £780 a year after tax if you are a basic rate taxpayer. Less than 1% a year, before any growth in the property's value.
So does that make it a bad investment? Not necessarily. Rents rise over time while an interest only mortgage stays the same, and the property should grow in value over twenty years even if it does very little in the next two. But you have to be honest about it. On today's numbers, this is a long term bet on rent growth and property 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 buy to let lender has to agree to lend. With a buy to let mortgage the main test isn't your salary, it is the rent. The Bank of England's rules for lenders say the rent has to cover the mortgage interest by a set margin, worked out at a higher test rate than you are actually paying. On fixes shorter than five years, that test rate must be at least the higher of 5.5% or two percentage points above your rate. Five year fixes sit outside that rule, so lenders set their own test, which is often closer to the real rate.
The usual margin is 125% of the interest for basic rate taxpayers, and 145% for higher and additional rate taxpayers, because they pay more tax on the rent. Every lender has its own rules, but here is 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%, the rent needs to be at least £1,074 a month.
- At 145%, it needs to be at least £1,246 a month.
At £1,250 a month, our higher rate buyer passes by just £4. Now look at what happens on a two year fix at the same 5%. The test rate jumps to 7%, and the rent would need to be £1,367 at 125% or £1,586 at 145%. The same property, the same rent, and it fails. The buyer would need a much bigger deposit, a five year fix, or a lender with a different approach. This is the first thing I would check on any property, and it is built into the checker below.
The Renters' Rights Act and the new rules for landlords
If you are thinking of becoming a landlord in England, this is the biggest change to renting in a generation, and it came into force on 1 May 2026. It doesn't stop you letting a property, but you need to go in knowing 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 re-let the property for 12 months afterwards. |
| Fixed terms are gone | Tenancies roll on month to month. Tenants can leave at any time with 2 months' notice. |
| Rent can rise once a year | You give at least 2 months' notice, and tenants can challenge a rise above the market rate at a tribunal. |
| Limits on rent in advance and bidding | 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 reasonably, and you can't turn someone down just because they have children or claim benefits. You can still check they can afford the rent. |
| Landlord database and ombudsman | A database of landlords and properties starts rolling out from late 2026, with an ombudsman for complaints to follow. |
Then there is energy efficiency. Privately rented homes in England will need an EPC rating of C by 1 October 2030, with spending capped at £10,000 per property. Plenty of older terraced houses sit at D or E, so check the certificate before you make an offer, and put any improvement costs into your numbers.
Buy to let now suits people who plan to hold for the long term and look after their tenants. If your plan is to buy, let for a year or two and then sell with vacant possession, the new rules make that slower and harder. Choose tenants carefully, keep good records, and budget for a longer gap if you ever need the property back.
Check your own numbers
Put in the property you are 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 would keep each year after tax if you own it in your own name. It uses 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 anyone 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 straight away.
- Properties with strong rent compared with price, which usually means outside London and the South East.
- Landlords who treat it as a business, keep the property in good order and budget for the bad months.
Worth thinking twice
- Higher rate taxpayers buying in their own name with a big mortgage.
- Anyone relying on the rent to cover 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 that you haven't budgeted to improve.
- Anyone hoping for a quick gain. Stamp duty alone can take years of profit to earn back.
Already a landlord by accident?
A lot of people didn't set out to be landlords at all. They moved in with a partner, or couldn't sell, and let the old flat instead. If that is you, the question is slightly different. You have already paid the stamp duty, so the question is whether to keep it, sell it, or change how it is financed.
- Check your mortgage first. If you are letting a property on a residential mortgage, you need your lender's permission, called consent to let. Consent is often temporary, so for a long term let you will usually need a proper buy to let remortgage.
- Run the numbers above on your current rate. If your fixed rate is ending soon, run them again at today's rates, as that is where many accidental landlords get a shock.
- If you are thinking of selling, work out the capital gains tax first, and remember the 60 day deadline to report and pay it.
- If you are moving and keeping your current home to let, my guide to let to buy explains how that works.
My honest take
I have been in mortgages for thirty six years, and I don't think buy to let is finished. People will always need homes to rent, and rents are still rising. But it has changed from something almost anyone could do on the side into a proper business with thin margins, more rules and higher taxes.
If you are a basic rate taxpayer with a good deposit and a long term view, and you can find a property where the rent is strong compared with the price, it can still be a sensible way to build wealth. If you are a higher rate taxpayer hoping for an income, do the sums very carefully before you commit, because the example above is not unusual. Either way, never buy on a hunch. Run the numbers, then run them again at a higher rate and with an empty month or two thrown in. If it still works, you are on the right track.

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.
