The rent carries £172,732 of the £277,500 loan

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

−£34,733 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 £147,658 you put in. The 5-year fix runs past this 5-year hold, so the rate reset comes after it.
