See imo the reason why it hasnt crash yet is unlike shares, people really can't monitor the performance and how well their properties are doing. In shares if you see it drop you sell sell! The person who doesnt get to sell their share are the losers.
In property, the event can be played over a very long time but when it does hit, then that's when its good to buy. Just need a few more rises in interest and you'll start seeing the market spiral downwards or move very slow. Very slow CG will result in less newbie investors who have been jacking up the price. Every 1/3 person I met whether it is a friend, cousin or relative has bought or is thinking of buying a house for the sole purpose of Capital gains. Now I'm aware most investors on this board are into it for the long run, however the same cannot be said for most of the ones out there at the moment.
Remember the good old days (yes just 3 years ago) when Microsoft shares were $120 per share? It was wayyy over-valued but it kept rising and rising until it could not longer be sustained. The latest Microsoft share taken (5/november/2003) is $26.07 a figure that's more appropriate and real.
It's just a matter of time people start realising this is just like a tech boom, except the only problem is that instead of real-time updates, you have to wait months to see any changes.
Take for example my pal Bob. His name has been changed for the sake of privacy. Now Bob has heard that a year ago, his pal bought a unit and sold it receiving $100K in capital gain. Bob knows nothing about real estate, he doesn't even have his own house but he loves the idea of making $100K in 1 year. Heck, Bob works his butt of day and night and only makes $30K a year. Bob tells all his pals he wants to buy a property. Bob makes all his friends excited and they too want to buy a property. Bob doesnt even know anything about yield or property management tips. Bob decides to folk out $500 to goto to a seminar to get more tips & knowledge. After he attends one, he is wild about buying properties because the guy at the seminar is telling him stories about how he made $0 and is now a multi-millionare driving Ferrari's around. Bob goes and buys 2-3 properties in a few months time. After a few months, Bob's properties CG skyrocket! Bob tells his pals, they all do the same thing. Now, not only is Bob buying buy all his friends are buying and doing the same thing.
History has proven that we repeat our mistakes. If the RBA didn't increase the rates, we would of been in a bigger mess. Think about it, if they didn't slow the market now and kept it going, a likely crash would of even be more realistic.
At the present time, no-one knows what's going to happen with this boom. Not even economists, seasoned investors. When something like that happens, its a huge risk. Best to come up with some contingency plans to save yourself in case anything happens coz it will.
