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 £375,000 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 24% 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.

What would you walk away with, after 5 years?The five-year sums

+£32,176 after five years on the cash you put in, before tax on the sale

More 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 £149,752 you put in. The 5-year fix runs past this 5-year hold, so the rate reset comes after it.
