Hi we are moving house to a much more expensive one, we are burrowing an extra £90,000. Our mortgage is self cert the rates for burrowing more arnt great, its either 6.99 fixed for 5 years or 4.5 variable (4 above base) I read today that interest rates might go to 2% by the end of next year, there is an arrangement fee of 195 for the fixed deal and no arrangement fee for variable, what do you think is the best one to opt for?
