Hard to imagine it'd be tolerable. Average cost of a home seemingly £277k so if you just took out a mortgage in the past few years you could realistically have a £200-250k balance. A 2% fixed rate jumping to 9% when remortgaging basically doubles the cost of that mortgage. You'd be paying circa £850-1000 a month more (so £10-12k a year more in mortgage payments).There was a report from the BoE that said 9% was tolerable. If I find it I’ll post it. Worth also considering that homeowners are usually much further up the earning and saving bands then non home owners. They are more able to withstand financial pressures.
