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 £230,000 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 the whole loan — it could fall 6% 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

Nothing here beats a plain let

Standard rental also ties up the least cash, £92,661.

Standard rental+£147 · £92,661 in

Rent by the room−£200 · £92,661 in

Housing-benefit rent−£317 · £92,661 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)

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

+£2,575 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 £92,661 you put in. The 5-year fix runs past this 5-year hold, so the rate reset comes after it.
