When to remortgage a BTL
UK landlords typically remortgage every 2–5 years to lock in the best available rate, raise capital from equity growth, or escape an expensive Standard Variable Rate after a fix ends. The mechanics are simple — but the economics aren't.
A product fee of £1,995 + £500 in legals + a £150 valuation means you start the new mortgage £2,645 down. That has to be recovered through the rate saving before the new product is truly cheaper than the old one. This calculator shows the break-even point in months and the net position over both 2 and 5 years.
Two rules of thumb: a remortgage where break-even falls within 18 months is almost always worth doing; one that takes longer than 30 months is usually only worth doing if you're also extracting equity for a further purchase.
