The straightforward route in — a single property let to one household for income and growth.
*Total return combines net rental income with long-run average UK capital growth. Illustrative and not guaranteed — property values can fall as well as rise.
Buy-to-let is the most established property strategy: you buy a property and let it to a single household on an assured shorthold tenancy, earning rental income with the potential for capital growth over time.
The classic single-let strategyBuy-to-let is the most familiar strategy for a reason: you buy a property and let it to a single household, usually on an Assured Shorthold Tenancy. It’s the most liquid, most mortgageable and most easily understood route into property — but the details around financing and tax are what decide whether a given deal actually works.
The things worth understanding before you buy:
A home someone wants to rentBuy-to-let has been reshaped by tax and tenancy reform over the past decade. None of it makes the strategy a bad one — it just means the numbers need modelling properly, not assumed from a headline yield.
Since April 2020, individual landlords can no longer deduct mortgage interest before tax — instead they get a flat 20% credit on finance costs, regardless of their tax band. Buying through a limited company avoids this restriction (interest remains fully deductible against corporation tax), which is why so many landlords now buy that way — though a company structure carries its own costs and isn’t automatically the right answer for every investor.
On sale, individuals pay Capital Gains Tax at 18% (basic-rate band) or 24% (higher-rate), after a £3,000 annual exemption — the same rates apply to non-UK residents selling UK property. Stamp Duty is 5 percentage points higher on any additional property, stacking with a further 2% non-resident surcharge, so an overseas buyer pays 7 points above the standard rate.
Published yield figures vary by methodology and shouldn’t be blended into one number: Zoopla puts the UK average gross yield around 6%, rising above 7.5% in parts of Scotland and the North East; Paragon Bank reported 7.21% UK-wide in Q1 2026; Fleet Mortgages recorded 8.1% across England & Wales in the same quarter. The spread itself is the lesson — a specific property’s real net yield always matters more than any national average.
Lenders typically require rental income to cover the mortgage at 125–145% of the payment (the “ICR”), assessed against a stress rate around 5.5% regardless of the actual rate offered — which is why the deposit and the rent both need to work together, not just the headline price.

One property, one tenancy. It’s the easiest strategy to get your head around and the most widely supported by lenders.
You earn monthly rent while the asset itself has the potential to appreciate over the long term.
Demand for good-quality family and professional rentals is broad and consistent across most of the UK.
A buy-to-let’s advertised gross yield is only the starting point. Running costs — management, maintenance, insurance and the odd void month — come out before you see a penny, and mortgage interest and tax come out after. The gap between gross and net is where good sourcing earns its keep.
Here is how a fairly ordinary single let might look, to illustrate the maths — not a specific deal or a promise of returns:
Illustrative figures only. Total return combines net rental income with an illustrative ~4%/yr capital growth (a long-run UK average, not a promise — values can fall as well as rise). Excludes mortgage interest and your personal tax position — take independent tax advice. This is not a forecast, an offer, or a guarantee of returns. Model your own, including leverage, on the calculator above.
Change any figure and the returns update live. Everything is calculated from your own numbers — nothing hidden, nothing inflated.
Illustrative only. Total ROI combines annual rental cashflow with your assumed capital growth on the full property value — growth is never guaranteed and prices can fall as well as rise. Assumes an interest-only mortgage and purchase costs of ~5% (stamp duty & legals); your stamp duty depends on your circumstances, so take independent tax advice. Personal tax is not included. Not a forecast, offer or guarantee. Want it run properly on a real deal? Send us your numbers ↓
“A well-chosen buy-to-let still earns its keep. The entire job is making sure it’s well-chosen — the right property, in the right area, at the right price.”
Yields are tighter than HMO, and a void means zero income until you re-let. Returns are sensitive to interest rates, and tax changes (such as Section 24) have squeezed higher-rate personal landlords. Where and what you buy matters more than ever.

Typically at least 25% of the purchase price for a buy-to-let mortgage, though it varies by lender and by whether you buy personally or through a company. Lenders also stress-test the rent against the mortgage payments (“rental cover”), so the achievable rent has to comfortably exceed the monthly cost, not just match it.
It depends on your tax position and your plans, and it’s genuinely an area for professional advice. Since mortgage-interest relief for individual landlords was restricted, many investors now use limited companies — but a company carries its own running costs and complexity. We’ll flag the trade-off and point you to a qualified tax adviser; we don’t give tax advice ourselves. Either way, work out the stamp duty on our stamp duty calculator before you commit.
Letting and management fees (commonly 8–12% of rent), maintenance and repairs, landlord insurance, safety compliance (gas, electrical and EPC), periods without a tenant (voids), and any ground rent or service charge if the property is leasehold. We build all of these into the figures, so the yield you see from us is net of costs, not a flattering headline.
The Renters’ Rights Act 2025 received Royal Assent on 27 October 2025 and its core reforms took effect from 1 May 2026: “no-fault” Section 21 evictions are abolished, every tenancy is now a rolling periodic tenancy rather than a fixed term, and rent can only be increased once a year via a formal notice. This is current law, not a future change — it affects every buy-to-let landlord in England, and we factor it into how we source and price every deal.
It can be — but the maths is tighter than it was a decade ago, which is exactly why running the numbers properly matters. A well-chosen, well-priced property in the right area still produces income and growth; a poorly-chosen one now struggles. Getting that selection right is the entire point of sourcing.
Yes — overseas investors buy UK buy-to-lets routinely, including with specialist expat and non-resident mortgages. Note that an additional stamp duty surcharge applies to non-UK residents and to additional properties, which is another reason to take independent tax advice. Our guide for overseas investors covers the process end to end.
It depends on your tax position and plans. Buying personally means mortgage interest only gets a 20% tax credit, not a full deduction; buying through a limited company (an SPV) keeps interest fully deductible against corporation tax instead, which is why it’s become the more common route for higher-rate taxpayers and anyone building a portfolio. Company purchases carry their own costs — different mortgage rates, accountancy fees, and tax on extracting profit as a director — so this is always worth a conversation with an independent tax adviser before you buy, not after.
Because they measure different things. Zoopla, Paragon Bank and Fleet Mortgages all publish credible UK yield figures, yet in the same period they ranged from around 6% to over 8% — the gap comes down to differences in sample, region weighting and methodology, not one being “right.” It’s exactly why we never quote a national average as if it applies to a specific property, and always show you the real net figures for the deal in front of you.
