Should You Borrow the Maximum on Your Mortgage?

Just because a lender will give you a bigger mortgage doesn’t mean you should take it. That’s the stark warning from mortgage brokers as high street lenders increasingly offer larger loans relative to what borrowers earn.

This week, NatWest announced it would lend up to 6.5 times annual income to joint applicants earning over £150,000. While this opens doors for some buyers, it’s also creating a false sense of security for others.

Gaurav Shukla, a mortgage broker at Marlow-based Home Me Mortgages, explains the real risk: “When you max out your mortgage, you’re left with little financial breathing room. If unexpected costs crop up or living expenses rise, your finances can come under pressure very quickly.”

The timing of these higher lending limits is particularly concerning. With inflation having only recently dropped, many people are assuming bills will continue falling. But that’s dangerous thinking. Energy costs, food prices, and other essentials could spike again over the coming months, especially if global events worsen. If that happens while you’re stretched to the limit on your mortgage, you’ll be in a difficult position.

Borrowing the maximum also leaves you vulnerable to lifestyle pressure. When bills rise, many people instinctively turn to credit cards and personal loans rather than cutting back. That’s when debt spirals quickly out of control.

Before taking on a larger mortgage, ask yourself some honest questions. How would you cope if your bills increased by £100 or £200 a month? Could you manage on one less holiday a year? Would you be prepared to eat out less? If the answer to these questions makes you uncomfortable, you’re probably borrowing too much.

The key is to be realistic about what you can actually afford, not what lenders are willing to offer. Speak to a mortgage broker about a sensible loan amount that leaves you with genuine financial security, not just the maximum possible figure. Your future self will thank you.
