A mortgage expert has warned buyers against waiting for the perfect time to secure a lower rate, coining the term 'Waiting Penalty' for the hidden costs of delay. Stephen Perkins, managing director at national broker Yellow Brick Mortgages, said the approach can backfire as rates begin to climb.
Rising rates trigger caution
With Halifax the latest lender to increase rates by up to 0.2% from tomorrow due to escalating Middle East tensions, borrowers who held out for lower rates may now regret their decision. Perkins cautioned that while waiting for rates to fall seems sensible, it ignores other financial factors.
“I refer to delaying for a better mortgage rate as the Waiting Penalty,” he said.
The bigger financial picture
Perkins noted that most people calculate potential savings from a 0.2% rate drop but neglect the cost of waiting itself. “We're all good at calculating the costs we can see, but it's the ones we don't see that often end up costing us the most,” he added.
He explained that house prices can rise, inflation can increase, lenders may tighten borrowing criteria, government policies can shift, and buyer demand can spike—all of which can outweigh any rate savings.
Real-world consequences
Perkins said he regularly sees buyers delay for a slightly lower rate only to find the desired property has increased in value, erasing potential savings. He also warned that if inflation rises, lenders may lend less, and rates have already increased over the past fortnight.
“The problem is that many buyers wait for all the planets to align: lower mortgage rates, stable house prices and the perfect property. But the reality is those conditions rarely arrive all at once,” he said.
Broker services and advice
Perkins pointed out that securing a mortgage now does not mean missing out if rates later fall—good brokers monitor the market and can switch clients to cheaper products before completion. However, not every broker offers this service, so buyers should ask in advance.
“Yes, mortgage rates matter, of course they do. But they're only one part of a much bigger financial picture. The next time you're tempted to wait for mortgage rates to fall just a little further, don't just ask yourself what you might save. Ask yourself what waiting might cost. That's your Waiting Penalty,” he concluded.
