Rented normally, it costs you £125 a month. That is £1,501 a year, every year you hold it.

Will it pay?Calculator

You top up £125 a month — the mortgage takes 58p of every pound of rent

Borrowing £23,087 less would close that shortfall — which is £23,087 more cash at the start, on top of the deposit.

And about £7,503 more over five years, because it loses £125 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 £111,830 of the £112,500 loan

That £670 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 rent carries the whole loan. Lenders test the rent at 7.5% and need it to cover 145% of the payment.

What would you walk away with, after 5 years?The five-year sums

−£12,155 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 £58,237 you put in. The 5-year fix runs past this 5-year hold, so the rate reset comes after it.
