Rented normally, it costs you £1 a month. That is £17 a year, every year you hold it.

Will it pay?Calculator

You top up £1 a month — the mortgage takes 40p of every pound of rent

Borrowing £258 less would close that shortfall — which is £258 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

£31,350 + refurb costs

And about £84 more over five years, because it loses £1 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 £90,000 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 the whole loan — it could fall 30% and still cover it

Your deposit is what limits this one, not the rent. Lenders test the rent at 7.5% and need it to cover 145% of the payment.

Which strategy wins?The ways to run it

Every way loses money — Standard rental loses least, at £1 a month

Standard rental also ties up the least cash, £38,480.

Standard rental−£1 · £38,480 in

Housing-benefit rent−£258 · £38,480 in

Short-stay let−£261 · £38,480 in

Each row: money kept a month, then the cash it ties up. Not compared: Rent by the room (only 1 bedroom) · Do it up, then remortgage (pays back at the remortgage) · Guaranteed council rent (no scheme in this borough) · Buy, improve & sell (pays out on sale)

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

−£4,199 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 27% in the price would leave nothing from a sale after selling costs, and you would still owe the lender any shortfall. That is the £38,480 you put in. The 5-year fix runs past this 5-year hold, so the rate reset comes after it.
