One couple I know, both on good salaries but one working p/t, borrowed the max they could when they bought approx 3 years ago. They are resigned to going on to an interest only mortgage when their deal ends. One of them works in one of the emergency services where it is the norm to retire at 50/after 30 years, and in ten years will have a pension lump sum that will be big enough to clear the capital, so if need be, that's what they'll do. They will be able to return to their job as a "civilian", so will still be earning good money for the remaining 15 years or so of working life.
Someone else I know has rented their house out because they can't afford the mortgage, and is now renting the annexe at their mother's house. Tbh, they never could only afford the mortgage before by having lodgers, but because they have 50/50 care of their young daughter, they don't want to have randoms moving in and all their friends now have their own places. It was the last lodger moving out that made them realise they couldn't afford to stay there.
A colleague is planning to rent out a room, possibly 2, when their fix comes to an end, another will downsize now that that all their kids are settled in their own places, which will reduce their outgoings significantly.
I feel bad for people who don't have these sort of options. It's grim.
