mars tbh I think it’s far too soon to say anything other than “right now, there are less buyers than pre-2020 for the typical starter flat”.
There’s the cladding scandal, covid and a year spent at home fresh in people’s minds, a huge economic storm brewing, the effect of wfh and whether or not that’s a blip... when we’re still practically in the middle of it it’s hard to draw conclusions.
I have had one friend among 20 or so over the past few years (interestingly, a single gay man) who “skipped the flat stage” and bought a semi in Bromley. I’d say that for most people though that would be an unusual decision - cities/city centres represent nightlife, friends, transport links, restaurants etc and I don’t think people typically look ahead 5-10 to consider schools, third bedrooms etc. It’s not just about the flat, it’s about the amenities it offers. And paying “just” another £100k or having “just” 20 minutes extra each way to commute might swing it.
Interestingly in my bit of SE London there is suddenly an abundance of school places, which means that pre-covid people with young families were moving out. Maybe this is part of a larger city/suburb cycle.
No one knows whether or not it’s a short-term trend, in sum.
