A fixed-rate mortgage can be a good option for those on a budget as the mortgage rate and your monthly repayments remain the same for the length of the deal. This is usually two, three or five years, but it can be as long as 10. Fixed rate mortgages can often start off more expensive than variable rate mortgages, but they will shelter you from any future rate rises and you’ll know exactly what your mortgage costs will be for the duration of the mortgage deal.
