sorry but this is half wrongMortgage interest will go up massivley over the next few years... after the fixed deal is over in 10 years, if you can't overpay in the interim, you should probably put any spare cash that you can't offset against your mortage into a beter investment vehicle, is what i'm saying...its just a maths/personal insurance thing.
Interest rates not can go up but they can go down...
