Will it pay?Calculator

You top up £458 a month — the mortgage takes 86p of every pound of rent

What will it cost me to buy?Breakdown

£139,525 + refurb costs

The rent carries £201,592 of the £300,000 loan

That £98,408 is yours to find on top of the deposit. Tested at 125% instead of 145% — a company or a basic-rate taxpayer usually is — the gap is £66,154. Lenders test the rent at 7.5% and need it to cover 145% of the payment.

Which strategy wins?The ways to run it

Every way loses money — Standard rental loses least, at £458 a month

Let it to the council: £1,644 a year less, but they keep paying when it is empty.

Standard rental−£458 · £156,269 in

Guaranteed council rent−£595 · £156,269 in

Housing-benefit rent−£952 · £156,269 in

Each row: money kept a month, then the cash it ties up. Not compared: Rent by the room (only 2 bedrooms) · Do it up, then remortgage (pays back at the remortgage) · Short-stay let (no local short-let data) · Buy, improve & sell (pays out on sale)

What would you walk away with?The five-year sums

−£43,737 after five years on the cash you put in, before tax on the sale

Less than the same cash would have made in a savings account, after tax on the interest. The savings account’s capital is not at risk; the property’s is. A fall of about 25% in the price would leave nothing from a sale after selling costs, and you would still owe the lender any shortfall. That is the £156,269 you put in. The 5-year fix runs past this 5-year hold, so the rate reset comes after it.
