Will it pay?Calculator

You top up £315 a month — the mortgage takes 94p of every pound of rent

Borrowing £58,104 less would close that shortfall — which is £58,104 more cash at the start, on top of the deposit.

That £66,820 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 £49,912. 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 £315 a month

Let it to the council: £864 a year less, but they keep paying when it is empty.

Standard rental−£315 · £96,342 in

Rent by the room−£322 · £96,342 in

Guaranteed council rent−£387 · £96,342 in

Housing-benefit rent−£604 · £96,342 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

−£28,350 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 27% in the price would leave nothing from a sale after selling costs, and you would still owe the lender any shortfall. That is the £96,342 you put in. The 5-year fix runs past this 5-year hold, so the rate reset comes after it.
