I can't see rates going up as quick as they came down so I would reckon a tracker is the way ahead for at least 2-3 years, look for get out costs, things like this don't often get mentioned up front only prduct fees, sols costs and valuation fees. When I left Halifax last year they wanted £175 for 'deeds dispatch fee' sending title deeds of house to another lender, £75 admin fee, and £75 quid for something else. I looked through the original paperwork from the last time I remortgaged with them and could only find £75 admin fee mentioned. They argued otherwise, I said 'I'll look on that Martin Lewis website' and they jsut went ok then £75 it is….
EDIT its worth the hassle for a garage, I couldn't live without mine now…
