I don't know how sustainable it will be MWF, but I'd like to try, just so the debt is gone sooner. Mainly cos I only own half the property, so the sooner I can pay it off, the sooner I can buy the other half, pay that off and own the entire thing.... Maybe I won't spend the rest of my life in this house (unlikely) but this is the approach I think I will take to it, as I guess the more of it (the property) I own, the bigger the profit will be on it when I sell. Also, the sooner the more capital in the mortgage is paid off, the less I will have to borrow again when I move/upgrade...?

My rough calculations tell me that if I overpay by £100 a week consistently, I could pay this mortgage off in around 15yrs (unless of course I am way off base)
