Rented normally, it costs you £156 a month. That is £1,877 a year, every year you hold it.

Will it pay?Calculator

You top up £156 a month — the mortgage takes 57p of every pound of rent

Borrowing £28,874 less would close that shortfall — which is £28,874 more cash at the start, on top of the deposit.

What will it cost me to buy?Breakdown

£42,375 + refurb costs

And about £9,384 more over five years, because it loses £156 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 the whole loan — it could fall 1% and still cover it

Your deposit is what limits this one, not the rent. 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 £156 a month

Let it to the council: £24 a year less, but they keep paying when it is empty.

Standard rental−£156 · £50,059 in

Guaranteed council rent−£158 · £50,059 in

Housing-benefit rent−£359 · £50,059 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

−£14,038 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 £50,059 you put in. The 5-year fix runs past this 5-year hold, so the rate reset comes after it.
