Rented normally, it costs you £947 a month. That is £11,369 a year, every year you hold it.

Will it pay?Calculator

The mortgage alone costs more than the whole rent — you top up £947 a month

It is £947 a month short. Borrowing £174,906 less would close that shortfall — which is £174,906 more cash at the start, on top of the deposit.

What will it cost me to buy?Breakdown

£192,825 + refurb costs

And about £56,844 more over five years, because it loses £947 every month you hold it — before any repair. That already assumes the rent never falls.

What would have to be true?The search

No offer makes this pay

Even at £327,000 — well below the £545,000 asked — the rent still does not cover the costs. The gap is the rent against the running costs, not the price, so negotiating does not close it.

What will the rent borrow?Lender test

The rent carries £194,377 of the £408,750 loan

That £214,373 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 £183,273. 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 — Rent by the room loses least, at £420 a month

Let it to the council: £1,320 a year less, but they keep paying when it is empty.

Rent by the room−£420 · £243,737 in

Standard rental−£947 · £209,737 in

Guaranteed council rent−£1,057 · £209,737 in

Housing-benefit rent−£1,320 · £209,737 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

−£81,550 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 25% in the price would leave nothing from a sale after selling costs, and you would still owe the lender any shortfall. That is the £209,737 you put in. The 5-year fix runs past this 5-year hold, so the rate reset comes after it.
