What does screw the market is the high number of private investors who are too highly geared and have to sell.
This then flows on to others who are doing everything right but because of falling sale prices which will be followed by falling rental prices are then also in the gun ad have to re-mortgage or sell.
So it becomes a snowball and as with most economic situations there only has to be about 15% of people in trouble for the damage to be done and the cards then start to fall, even places like the CBA can't withstand a fall of 15% of their loans to go broke
