Rented normally, it costs you £14 a month. That is £172 a year, every year you hold it.

Will it pay?Calculator

You top up £14 a month — the mortgage takes 74p of every pound of rent

Borrowing £2,640 less would close that shortfall — which is £2,640 more cash at the start, on top of the deposit.

What if I change my assumptions?The dials

At the asking price, 25% deposit, 6.50% charged

Change any of these 16 and every card on this page changes with it. The 6.50% is the 5.75% quoted plus a company premium.

What will it cost me to buy?Breakdown

£194,650 + refurb costs

And about £858 more over five years, because it loses £14 every month you hold it — before any repair. That already assumes the rent never falls.

What would have to be true?

Break-even is within £5,000 of the asked price

It lands that close to the £550,000 asked — inside the step this card rounds to, and inside the confidence band on the rent it works back from. So the price asked is already about the price this rent carries, and there is no honest discount to print.

What will the rent borrow?Lender test

The rent carries £320,531 of the £412,500 loan

That £91,969 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 £40,685. 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

−£44,920 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 31% in the price would leave nothing from a sale after selling costs, and you would still owe the lender any shortfall. That is the £290,902 you put in. The 5-year fix runs past this 5-year hold, so the rate reset comes after it.
