I'd say it's pretty obvious.. the 2000s boom in crazy multiples by lenders leading to too much of the population exposed to ANY drop in value.
I mean prices ought to just be stagnating but things like help to buy are pouring petrol on a fire.. it's blatantly obvious that it's not sustainable yet we persist in finding ways to perpetuate the pricing we've got now.
That and the entirely human instinct to gather wealth leading to "increasing value" int he roof over your head being a primary motivator for people rather than just having a "house" as we used to call them.
I'll be honest, I don't see a way out.. we can't have a crash, we can't continue like this...
I think the only sensible way out is government stepping in and actually building houses rather than propping up the mortgage market and basically forcing the market into a managed stagnation.
But that'll never happen because your average person is greedy and wants their house to go up in "value" totally ignorant to the fact that every other house necessarily has to go up to support such a rise.
Humans..
oh and.. in before "immagrunts"
