Why is it not a realistic option? You can’t just move to the best, biggest or dream house surely? (Well, you can, but then you risk not being able to afford it like is happening now). There’s also a big difference between a crap house in a crap area & a 4 bed detached in a lovely area. Unfortunately some will only accept the latter.
My friend bought a lovely big house (dream house) 4 beds & it’s her, her DP & 1 child, had loads of work done to it, got a nice car to park on the drive & now can’t afford it.
I bought a mobile home to live in, then I bought a flat, then I bought a terrace in a not so nice area, now I’ve bought a small house in a lovely area. Each sale, I’ve made a bit. I also don’t buy anything at all before I’ve saved up all the money for it, not even my car. And I have a crap paid job.
Everyone is different of course but the sense of entitlement these days.
