@jgw1 I have to say that I haven't got a clue. If it stays small it might be ok, if not we are truly screwed.
If people can't buy and sell then the housing market is likely to crash I would think, as people struggle with higher interest rates and negative equity. It looks fubar.
I have no financial training though so I could be totally wrong, it just seems that this is the most likely scenario to me trying to put myself in the position of those struggling.
