Rented normally, it costs you £96 a month. That is £1,152 a year, every year you hold it.

Will it pay?Calculator

You top up £96 a month — the mortgage takes 75p of every pound of rent

Borrowing £17,719 less would close that shortfall — which is £17,719 more cash at the start, on top of the deposit.

Which strategy wins?The ways to run it

Rent by the room beats Standard rental by £420 a month

Let it to the council: £1,368 a year less, but they keep paying when it is empty.

What would you walk away with, after 5 years?The five-year sums

−£14,456 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 26% in the price would leave nothing from a sale after selling costs, and you would still owe the lender any shortfall. That is the £108,425 you put in. The 5-year fix runs past this 5-year hold, so the rate reset comes after it.
