Buy-to-let property for sale: buying on the numbers
Most buy-to-lets advertised as investments are priced for a buyer who has not done the maths. Once stamp duty, finance, management, voids and maintenance are in, a headline 8% often becomes a real 4%. We define the buy box first, then only look at stock that clears it.
A buy-to-let for sale is worth buying when the rent covers the debt with margin and the net yield on total cost meets your target. Total cost means purchase price, the additional-property stamp duty surcharge, legal and survey fees, and any refurbishment. Net income means rent less voids, management, maintenance, insurance, licensing and service charge. Lenders apply their own stress test on the rent, which often sets the maximum you can borrow long before the price does.
What the market looks like
Stamp duty surcharge
The additional-property surcharge is a real cost on day one and changes the yield on smaller purchases most.
Lender stress testing
The rent must cover the mortgage with a buffer at a stressed rate, which limits leverage in low-yield areas.
North versus south
Higher yields in the north, stronger long-run growth in the south — pick which one your plan needs.
Licensing spread
Selective licensing now covers many areas, adding a cost per property that few listings mention.
What to check before you offer
Achievable rent
Evidence from let comparables, not asking prices on portals.
Real yield
Net income divided by total cost including stamp duty, fees and works.
Service charge and ground rent
On flats these can wipe out the margin entirely — get the actual figures.
EPC rating
Poor ratings mean capital spend to keep the property lettable under future standards.
Licensing
Check whether the local authority operates a selective scheme covering the address.
Tenant demand
Void risk is the return killer. Check how long comparable properties sit before letting.

Buy-to-let property for sale: common questions
What is a good yield on a UK buy-to-let?
The honest answer depends on the finance and the area, but the useful test is whether net income after every cost still meets your target once the mortgage is stressed at a higher rate. A high gross in a high-void area is worse than a modest gross that never sits empty.
Is buy-to-let still profitable in the UK?
It is, but the margin now comes from buying well rather than from rising prices. Tax treatment of finance costs, the stamp duty surcharge and higher rates all mean the purchase price and the running costs decide the outcome.
Should I buy through a limited company?
Many investors do because of how finance costs are treated, but it depends on your income, your plans and your exit. It is a question for your accountant before you offer, not after you complete.
