That is a gross assumption on your behalf, many have a variety of investments. The same argument could be applied to anyone who just puts all their money into shares. There are different houses in different areas, just like there are different shares, some are good buys some are bad buys, some are good performers and some are bad performers.

Wow property is such a bad investment. Since it is such a bad investment how about stop wasting everyone's time telling them it is a bad investment and move on to something that is a good for you! Many people can and do make money out of property even now and will continue to do so even if some things change.
