isn't there a penalty for over payment? I'm sure you can't just walk into the building society and slap down a cheque for £5000. I think on my mortgage you can only overpay by £500 per month. I think the best time is when your mortgage is up for renewal...ie after 2/3 years
on my mortage, every january you can pay off upto 10% of your mortage without a penalty but only in january
