My current deal is coming to an end and I’m wondering whether to fix for 2 or 5 years. We don’t currently have plans to move but may do in the next few years as we are starting a family. We currently have a large 4 bed end terrace but if the right detached property came up in the medium term we would be interested. The 2 year rate is better in the short term but I’m concerned that with Brexit etc. the only way is up for interest rates.
