Speculators get burnt all the time, they have a sook for awhile, then before you know it they are getting a margin loan.
It may cause a minor ripple, or it may cause a surge in consumer sentiment, when people actually see house prices falling.
The losers, investors who have geared into property with a capital gain being the sole underpinning rationale.
The winners, the government, tenants and prospective home buyers.
I think there are a lot more 'naive' speculators among property investors. We are not talking doctors with margin loan accounts who lose when the stock market goes into a bear market. We are talking people on $70,000-$80,000 who aren't going to take a loss lightly.
