Which strategy wins?The ways to run it

Every way loses money — Standard rental loses least, at £777 a month

Let it to the council: £9,324 a year less, but they keep paying when it is empty.

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

−£78,712 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 £271,531 you put in. The 5-year fix runs past this 5-year hold, so the rate reset comes after it.
