@pepperpiper While new people come to the market, this is balanced by people exiting the market (probate, returning overseas etc). As another poster said above, there's not a shortage of property (there are not swathes of homeless middle class people littering the streets) but there is a misallocation of property. People will always need to buy, but the fact remains they can only pay what they can borrow, making prices a function of credit.
I think we broadly agree on a few points. In 2008 it was criminal what people were allowed to borrow, and self cert was common, although no lessons have been learned and people will default again soon. I also agree that the majority of people are still borrowing and will continue to, but that borrowing is curtailed by higher rates, so that + less affordability = lower prices. Yes, the majority of people can still pay their mortgages, or have no mortgage, so are unaffected, but prices are set by the people who have to buy and sell (death, divorce, debt, relocation), and that is a function of credit.
Whether we have a crash, a 10% drop or a flatlining of prices is in the hands of interest rates.
