Rented normally, it costs you £419 a month. That is £5,027 a year, every year you hold it.

Will it pay?Calculator

You top up £419 a month — the mortgage takes 89p of every pound of rent

Borrowing £80,437 less would close that shortfall — which is £80,437 more cash at the start, on top of the deposit.

What will it cost me to buy?Breakdown

£166,525 + refurb costs

And about £25,137 more over five years, because it loses £419 every month you hold it — before any repair. That already assumes the rent never falls.

What would have to be true?

We cannot price this without a postcode

Which purchase tax applies — stamp duty, LBTT or land transaction tax — is decided by the nation the address sits in, and this listing carries no postcode to resolve it. Rather than assume England and then price to the pound off it, this card does not answer. The agent can give you the postcode.

□ no postcode on the listing

What will the rent borrow?Lender test

The rent carries £220,371 of the £356,250 loan

That £135,879 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 £100,619. 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

−£42,719 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 £179,984 you put in. The 5-year fix runs past this 5-year hold, so the rate reset comes after it.
