We've got 2 mortgages on our property (as we ported our original one over when we moved). We are now in a position to start to overpay, but should we overpay on the mortgage with the largest amount (but with a lower interest rate of 2.09%) or the smallest amount (with a higher interest rate of 2.5%)?
I'm wondering if there's an easy way to work that out? I know credit cards you should pay off the one with the highest interest rate first, but mortgage rates are relatively low and the difference between the rates is quite small.
Any views from others?
