A very basic question: how does overpaying work? I know what the limits are for how much I can overpay, but do you have to spread this out each month or can you make one massive payment near the end of your fixed term? That would allow me more flexibility because presumably once the money is paid in it's not easy to get back out without remortgaging.
You can pay whenever you like but the sooner you pay the sooner you start saving interest (obviously). If you reach your repayment charge limit clearly you can do it at remortgage time (just borrow less)
