i think it depends on your situation. There’s no one solution for everyone. If you currently own, are paying capital, and don’t HAVE to move, then you probably can wait to see if house prices reduce.
But if you rent at £1000 a month and can get a mortgage at £300 a month for the same size and location, it would be a very different question, and I certainly wouldn’t call them batshit. I don’t think it’s ever a good idea to overextend yourself (ie max borrowing) or plan to buy a house to keep for only a couple of years. But if you have financial safety nets, even in the event of a house price crash, or dip, you can wait it out. My parents couldn’t move in 1989 because of the crash so they stayed put for another few years and it was fine.
Inflation and recession doesn’t address the large problem of shortage. Since the 2007 recession, banks had to tighten their lending a lot so the volume of defaults won’t be repeated. People who can stay to avoid selling at a loss, will. And this reduces the number of ‘starter’ properties available. Which keep demand and competition high.
If people are losing to cash buyers now, it will get worse. if there’s a house price crash/ slump, with higher interest rates, cash buyers will clean up on houses while those needing a mortgage meet stricter criteria. So again, if you’re currently renting and will be a FTB, you’re not necessarily going to be hugely helped by a crash/ slump.
