How to buy an investment property in the UK

Eight steps, in the order you meet them, each one pointing at the calculator or report on this site that does that step's arithmetic. Nothing here quotes a rate: rates move, and the calculators hold the current ones.

1. Step 1

   Work out the cash you actually need up front

   Before anything else, find the number that has to leave your bank account. It is the deposit — the slice of the price you pay yourself rather than borrow — plus stamp duty, plus the legal and survey fees. Stamp duty is where most first budgets go wrong, because a property you are not going to live in is charged at a higher rate than a home, and that extra sits on top of the whole price rather than the top slice of it.

2. Step 2

   Find out what a lender will lend, not what you hope it will

   A buy-to-let lender does not size the loan against your salary. It sizes it against the rent, and it does that at a made-up interest rate higher than the one you will pay, to check the rent would still cover the payments if rates rose. That test is why a property can look affordable and still be refused. Run the payment at a few rates before you offer, so a rate rise is something you have already seen rather than something that arrives with the mortgage offer.

3. Step 3

   Learn the difference between yield and cashflow

   Yield is the rent measured against the price. Cashflow is what is left in your pocket after the mortgage, the insurance, the management fee, the void weeks when nobody is in, and the repairs. They answer different questions, and a property can have a good yield and negative cashflow at the same time. Cashflow is the one that decides whether you can hold the property; yield is the one that lets you compare two of them.

4. Step 4

   Pick an area on evidence rather than on a hunch

   An area is a decision about rent, about how long a property sits unsold, and about what you can sell it for later — not about whether you like the high street. Look at what the same kind of property rents for across a city, and then at what is actually on the market there today, rather than at one listing you happened to find. How quickly rentals are taken in a city is the other half of that picture: a place where they go slowly is a place where your empty weeks are somebody else’s normal.

5. Step 5

   Line up the survey and the solicitor before you offer

   The survey and the conveyancing solicitor are the two people who can still stop the purchase, and both take weeks to book. Get the numbers settled first so the money you spend on them is spent on a property that already works on paper — paste the listing in and read the report before you instruct anybody.

6. Step 6

   Check the EPC and whether the property needs a licence

   Three rules can make a property unlettable rather than merely expensive. The EPC — the energy rating on the certificate — has a legal floor below which letting is an offence, and a tightening deadline behind it. Separately, some councils have an Article 4 direction, which removes the automatic right to turn a family house into a shared house and makes it a planning application instead. Third, the council may require a licence before you let at all: every council must license a house shared by five or more people from more than one household, which is mandatory licensing; many run an additional scheme that catches smaller shared houses; and some operate selective licensing, which requires a licence for every rented home inside an area they have named. Which of the three applies is the council’s decision for that address, so ask them before you offer — all of this is much cheaper to find now than after completion.

7. Step 7

   Price the rent before you go looking for a tenant

   The rent you can charge is set by what comparable properties nearby are actually let for, not by what you need to cover the mortgage. Decide that figure before completion, because it is the input every other number on this page depends on, and read how the estimate is built so you know what it does and does not include.

8. Step 8

   Decide now how you get your money back out

   There are two ways out and they are taxed differently: refinance and keep the property, or sell it. Refinancing releases cash against the new value and is not itself a taxable event; selling crystallises a capital gain, and the tax on that gain is a bill you should have modelled before you bought, not after you accepted an offer.
