How to cut your mortgage interest bill in half

Many homeowners may be able to significantly reduce the total interest paid on their mortgage by making small, consistent changes to their repayment strategy and loan structure.

Simple adjustments such as maintaining higher repayments when rates drop, or adding small extra payments when possible, can have a meaningful impact over the life of a loan. Reviewing loan structure regularly and considering how different fixed terms work together can also improve flexibility and long-term cost efficiency.

Key Mortgages director Jeremy Andrews says many borrowers are surprised at how much difference small changes can make over time.

"Even small, consistent increases in repayments can have a significant impact on reducing the total interest paid and shortening the overall loan term," he says.

He adds that borrowers who take a proactive approach to their mortgage structure are often in a stronger long-term position.

"Clients who regularly review their lending structure and keep repayments steady or slightly higher tend to see the biggest long-term savings,'" Andrews says.
