Reducing Your Mortgage May Not Be the Smartest Strategy

With interest rates elevated and the number of UK mortgage deals shrinking on a daily basis, many borrowers are seeking to shore up their finances by paying down their home loans early. However, just because you can doesn’t mean you should.

In just the past week, HSBC Holdings Plc and Banco Santander SA have both suddenly withdrawn several mortgage products, while National Westminster Bank Plc, Halifax, and Nationwide Building Society have all hiked their fixed-rate deals. As of last week, a typical two-year fixed rate deal on a 75% loan-to-value mortgage was 5.24%, compared with barely 1% as recently as September 2021. So does it make sense to reduce your outstanding mortgage balance by overpaying the principal?

The problem with using spare cash to pay down a mortgage is that you typically cannot draw the money back in the event of a crisis. Dipping into your emergency stash to trim your borrowings can significantly reduce your financial flexibility. Most advisers suggest that you should have sufficient funds to cover between three and six months of expenditure, to insure against unforeseen circumstances.

Instead, it might be better to accumulate any surplus in a savings account. In previous interest-rate cycles, it was pretty difficult to keep opening and closing savings accounts to track the best deals. These days, online platforms make staying competitive much easier. You deposit your money with any one of roughly half a dozen different providers and are then free to seek the best deal on the platform at the click of a mouse. The best three-month deposit accounts pay close to 4.75% and a six-month term deposit offers about 5%, both comfortably above the Bank of England’s 4.5% interest rate.

If you’re looking to refinance an expiring fixed-rate mortgage deal, you have two further options to soften the blow of rising rates. You could pay down just enough of your mortgage to drop into a lower LTV bracket. According to property portal Rightmove Plc, a typical 95% LTV five-year fixed-rate mortgage costs 5.50%, but that drops to 5.22% at the 90% category. That might be worth aiming for if you are just above the threshold.

Alternatively, an offset mortgage allows you to retain personal liquidity while reducing monthly payments. The products “offset” savings you have with your lender against money owed on your mortgage. Instead of being paid interest on your savings, which might be taxable, you save interest on your mortgage, which is more tax efficient. An additional advantage, compared to simply prepaying a mortgage, is that any cash you hold in your offset savings account is available to be withdrawn should the need arise — an efficient means of making your emergency cash work harder.
