Rented normally, it costs you £765 a month. That is £9,181 a year, every year you hold it.

Will it pay?Calculator

You top up £765 a month — the mortgage takes 80p of every pound of rent

Borrowing £141,250 less would close that shortfall — which is £141,250 more cash at the start, on top of the deposit.

What will it cost me to buy?Breakdown

£195,100 + refurb costs

And about £45,906 more over five years, because it loses £765 every month you hold it — before any repair. That already assumes the rent never falls.

Which strategy wins?The ways to run it

Every way loses money — Standard rental loses least, at £765 a month

Let it to the council: £11,616 a year less, but they keep paying when it is empty.

Standard rental−£765 · £209,255 in

Guaranteed council rent−£1,733 · £209,255 in

Housing-benefit rent−£2,013 · £209,255 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)

◧ 3 ways, one measureranked on money kept each month, at the asking price

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

−£69,516 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 24% in the price would leave nothing from a sale after selling costs, and you would still owe the lender any shortfall. That is the £209,255 you put in. The 5-year fix runs past this 5-year hold, so the rate reset comes after it.
