Rented normally, it costs you £170 a month. That is £2,038 a year, every year you hold it.

Will it pay?Calculator

You top up £170 a month — the mortgage takes 78p of every pound of rent

Borrowing £31,347 less would close that shortfall — which is £31,347 more cash at the start, on top of the deposit.

What will it cost me to buy?Breakdown

£67,200 + refurb costs

And about £10,188 more over five years, because it loses £170 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 £110,981 of the £150,000 loan

That £39,019 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 £21,262. Lenders test the rent at 7.5% and need it to cover 145% of the payment.

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

−£20,327 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 29% in the price would leave nothing from a sale after selling costs, and you would still owe the lender any shortfall. That is the £91,800 you put in. The 5-year fix runs past this 5-year hold, so the rate reset comes after it.
