Re: overpaying. I am planning to do this as much as I am able over the new 5 yr fix. The way I see it is that I am increasing my equity in the place so that when it comes to renew or sell, my LTV will be more improved than just paying the mortgage itself. Also (and someone might be able to correct me here if I have misunderstood), as you are making the overpayments, you are reducing the loan amount more quickly than the standard payments, so the amount charged in interest each month reduces, meaning that you regular payments start to pay off an increasing amount of the loan also, effectively themselves becoming overpayments. Hence the exponential-ish nature of those overpayment calculators.
What are they paying at the moment? Last time I bothered with that shit I don't think it was worth it. Probably forgot to factor tax into that though or something dumb.
