My heads in a whirl - we need to remortgage to raise funds for an extension - mortgage is relativly low and were currently on 1.5% variable but willl be doubling our lending - to be abe to afford to live comfortably and happily we are considering a full remortgage rather than an additional loan - i am clueless - should we fix and if so for how long would you as i keep reading scarey threads about 12% etc - am tempted to fix now for 2-4 years but dont think rate will shoot up in next 12 months so would potentially miss out on variable savings. God someone educated please help me.
