Most banks offer an offset account that helps you minimise your interest. Some mortgage borrowers prefer this strategy over paying a fixed extra repayment each month, as they still have control of their offset funds. If needed, you can make the extra repayments into your offset account, and dip into your offset funds when you want to do a small renovation, a building emergency or even for a holiday, or it can just sit there working away at saving you interest. It’s a win-win for borrowers.
