What will it cost me to buy?Breakdown

£153,750 + refurb costs

The rent carries £212,414 of the £330,000 loan

That £117,586 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 £83,600. 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 £364 a month

Let it to the council: £4,668 a year less, but they keep paying when it is empty.

Standard rental−£364 · £173,208 in

Rent by the room−£650 · £173,208 in

Guaranteed council rent−£753 · £173,208 in

Housing-benefit rent−£907 · £173,208 in

Each row: money kept a month, then the cash it ties up. Not compared: 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

−£39,612 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 £173,208 you put in. The 5-year fix runs past this 5-year hold, so the rate reset comes after it.
