The problem with property when it falls - as it is most certainly doing today - is the losses are amplified due to borrowing.
a Long term shareholder often buys on a dollar average basis and with disposable income - not borrowing - so you get more shares when prices fall.
A 25 year housing loan, even when you've only paid $40,000 over the price - may turn out to be many multiples of that over the years if interest is included.
With the ever increasing glut/surplus of properties for sale - no wonder people are waiting on the sidelines - as further price falls over the next few months can be expected.
