I need some expert advice here and would be grateful for any info. My brothers 2 year fixed rate buy to let mortgage is coming to an end in 4-5 months. Is it too early now for him to start looking for remortgage possibilities? With interest rate quite low, he'd probably be better off w/t a fixed rate. But no one knows what tomorrow will bring, so he wants to see what fixed rates are available and when he should seriously start thinking about it.
