We arranged a 5 year fix back in September at 2.84% which started this January.
Not a brag - we're late to the house buying thing as didn't manage to save the deposit til we were in our late 40s/early 50s, with two teenagers who need their own rooms, and so as we're paying off the mortgage over a shorter length of time it already takes up half of our combined salary.
We can't take any chances, and even back then it was starting to go up (just before the disastrous Truss/Quarteng government) and was being predicted to carry on. On our fix we now pay £300/month extra, but if we'd waited we'd be paying over £1K more a month which would be a disaster.
Even now, all it would take is for one of us to lose our job for 3 months and we'd quickly go under.
In 5 years, the payments will be easier to cope with as teens will hopefully be in their 20s and will be either working and buying their own stuff (and contributing to bills) or living elsewhere and paying their own way. Hopefully our wages will be higher too to cope with the extra payments.
If we were paying what's outstanding on our London flat (almost 500K) at 6%, we'd be selling up and giving up on home ownership altogether at our age.
