Bit harsh. Few of my wife's family are Tory voters, they've mostly been brainwashed by media beholden to right wing interests. Lovely people, but having poison poured in their ears on a daily basis.
Lot can happen in 4 years.
I'm preparing for it now, have taken what I would expect to be the payment in 2027, and set half the difference into savings. Take some of the pain now, start adjusting to higher payments and by the time it comes to remortgage, should have a decent sized pot to pay a chunk of it down.
I'd be surprised if salaries aren't rising in real terms by this time next year too. Unless you're getting shafted, your salary should be rising at a rate significantly higher than your interest rate, s relative terms, your mortgage is going down fairly rapidly.
To bring that to life, sticking those numbers into a calculator and assuming you're on a 20 year mortgage, little under £2k a month and £80k a year household income, by 2027, you'd have £329,882 outstanding.
In current terms, you go from 5x to a smidge over 4x income.
If you get say 6% pay rises a year, your income by 2027 would be £101k, which means your mortgage is only 3.3x income.
If you take that back to today, with a 6% mortgage, it'd be the equivalent of £2,160 as a monthly payment, so not a crazy amount more
