10 years is a long time to fix, 5 year rates are below 1.5% so almost below inflation, that's what we're going for next.
We overpay 10% each year, usually in little bits every 2-3 months. The other thing to consider if you can afford repayments is to shorter the term, we are currently on a 20 year mortgage instead of 25 years, that combined with overpayments has dropped our LTV from 70% to under 50% in just over 3 years, which leaves us with loads of options going forwards.
There is something to be said about maximising you mortgage borrowing at the moment given the low interest rates, but only if you have something worth spending the money on (not a car
), otherwise your still taking on extra debt for no reason regardless how cheap borrowing is.
