Rented normally, it costs you £433 a month. That is £5,199 a year, every year you hold it.

Will it pay?Calculator

The mortgage alone costs more than the whole rent — you top up £433 a month

It is £433 a month short. Borrowing £79,981 less would close that shortfall — which is £79,981 more cash at the start, on top of the deposit.

What will it cost me to buy?Breakdown

£75,575 + refurb costs

And about £25,994 more over five years, because it loses £433 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 £135,000 — well below the £225,000 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.

The rent carries £89,655 of the £168,750 loan

That £79,095 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 £64,750. 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 £433 a month

Let it to the council: £828 a year less, but they keep paying when it is empty.

Standard rental−£433 · £86,277 in

Guaranteed council rent−£502 · £86,277 in

Housing-benefit rent−£641 · £86,277 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, after 5 years?The five-year sums

−£33,489 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 £86,277 you put in. The 5-year fix runs past this 5-year hold, so the rate reset comes after it.
