As I have said before, shouldn't you want problems to drive prices down?... That's one thing I'm raising, is asking you to consider the harm to society. The other thing I'm raising is that we're now in a tightening liquidity environment where interest rates are shooting up. The "punch bowl" is being pulled away, and real estate people aren't used to that. I think it's in their own best interest to deleverage because this is going to become dangerous for them. If interest rates really keep rising, property investors are going to have lots of problems.
I've also said before that I suspect that if the amateurs you are concerned about did follow your recommendation and sold, the bigger players with deep pockets will snap up the properties for little change to affordability.
