What would have to be true?

Nothing — it works at the asking price

The rent covers the mortgage, the running costs and the tax at the £259,000 asked, so there is no discount this card has to name. A lower price would be upside, not a condition.

What will the rent borrow?Lender test

The rent carries £166,260 of the £194,250 loan

That £27,990 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 £1,388. Lenders test the rent at 7.5% and need it to cover 145% of the payment.

Nothing here beats a plain let

Let it to the council: £2,832 a year less, but they keep paying when it is empty.

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

−£6,027 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 26% in the price would leave nothing from a sale after selling costs, and you would still owe the lender any shortfall. That is the £102,796 you put in. The 5-year fix runs past this 5-year hold, so the rate reset comes after it.
