Because it might be all they will offer you.
Many mortgage-holders would be delighted to remortgage – but find that they can’t. An estimated quarter of a million homeowners are so-called ‘mortgage prisoners’, stuck on an SVR mortgage against their will and unable to switch. This is often because of tighter lending criteria introduced since the 2008 financial crisis, resulting in borrowers being refused new mortgage deals on the properties on which they already have a mortgage.
Absurdly, this means that these homebuyers can’t remortgage to a deal that would result in far lower monthly payments than they are currently paying on their SVR mortgages. What makes the problem worse is that many are with lenders who have ‘closed books’, meaning that they are currently inactive and cannot offer new deals. If they can’t get a mortgage deal via a different lender, they remain stuck on their punishing SVR.
