Remortgage for new fixed rate or pay variable?

TCvii

Hi all,

Apologies if this is a basic question but my (shared ownership) mortgage 2 year fixed rate is coming to an end in a few months time and I’m not sure on what would be a sensible approach.

i will be looking to sell my flat in the first half of next year, with the plan of getting a larger place with my OH. Would it be sensible to remortgage my flat on a new fixed rate, or should I pay the variable rates for a couple of months?

if I sell early on in a fixed rate deal (I assume I’d go for a 2 year deal) are there significant charges I should bear in mind?

thanks for your help!
