£50,450 + refurb costs

The rent carries £78,939 of the £112,500 loan

Which strategy wins?The ways to run it

Every way loses money — Guaranteed council rent loses least, at £101 a month

Let it to the council and you keep £108 a month more, and they keep paying when it is empty.

Guaranteed council rent−£101 · £57,937 in

Standard rental−£209 · £57,937 in

Housing-benefit rent−£296 · £57,937 in

Each row: money kept a month, then the cash it ties up. Not compared: Rent by the room (only 1 bedroom) · 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

−£17,325 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 £57,937 you put in. The 5-year fix runs past this 5-year hold, so the rate reset comes after it.
