Rented normally, it costs you £218 a month. That is £2,610 a year, every year you hold it.

Will it pay?Calculator

You top up £218 a month — the mortgage takes 65p of every pound of rent

Borrowing £40,160 less would close that shortfall — which is £40,160 more cash at the start, on top of the deposit.

What will it cost me to buy?Breakdown

£49,075 + refurb costs

And about £13,052 more over five years, because it loses £218 every month you hold it — before any repair. That already assumes the rent never falls.

What will the rent borrow?Lender test

The rent carries £95,597 of the £108,750 loan

That £13,153 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 rent carries the whole loan. 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 £218 a month

Let it to the council: £108 a year less, but they keep paying when it is empty.

Standard rental−£218 · £59,156 in

Guaranteed council rent−£227 · £59,156 in

Housing-benefit rent−£429 · £59,156 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

−£18,902 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 £59,156 you put in. The 5-year fix runs past this 5-year hold, so the rate reset comes after it.
