Will it pay?Calculator

You top up £591 a month — the mortgage takes 87p of every pound of rent

Borrowing £109,196 less would close that shortfall — which is £109,196 more cash at the start, on top of the deposit.

And about £35,489 more over five years, because it loses £591 every month you hold it — before any repair. That already assumes the rent never falls.

The rent carries £271,088 of the £412,500 loan

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

−£54,611 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 23% in the price would leave nothing from a sale after selling costs, and you would still owe the lender any shortfall. That is the £197,200 you put in. The 5-year fix runs past this 5-year hold, so the rate reset comes after it.
