Unfortunately, mortgages taken out before and at the beginning of the pandemic were not stress-tested for the inflation we have today.
@TonyTeacake how do you know? When I took my mortgage out they told me what the repayments would be if interest rates hit double digits. Eye watering, yes, but still possible to pay.
Lots of people talk about people 'overstretching' themselves on a mortgage, but you can't do that these days.
