Will it pay?Calculator

What will it cost me to buy?Breakdown

The rent carries £267,162 of the £435,000 loan

That £167,838 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 £125,092. 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 £831 a month

Standard rental also ties up the least cash, £220,490.

Standard rental−£831 · £220,490 in

Housing-benefit rent−£1,459 · £220,490 in

Rent by the room−£1,812 · £220,490 in

Each row: money kept a month, then the cash it ties up. Not compared: Do it up, then remortgage (pays back at the remortgage) · Short-stay let (no local short-let data) · Guaranteed council rent (no scheme in this borough) · Buy, improve & sell (pays out on sale)

◧ 3 ways, one measureranked on money kept each month, at the asking price

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

−£75,057 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 £220,490 you put in. The 5-year fix runs past this 5-year hold, so the rate reset comes after it.
