Nope. One is loadsa people trying to sell, the other is fewer people looking to buy.
As for those reports you mention, ask yourself who publishes them.... think about it now, what interest might a bank or an estate agent or the construction industry have in reinforcing positive sentiment?
Listen, if there was a shortage of housing then rent would be much more expensive. It isn't because there isn't any shortage.
There is, or rather there has been, a shortage of housing for sale because specuvestors have held onto properties for capital appreciation. These guys will let these go once they start costing (or stop making) them money, they wouldn't own them in the first place if they weren't in it for the money.
I agree. This is a speculative market its important to remember that. Many people bought because prices were going up when prices stop going up many people will stop buying, the market will revert to fundamentals. But the fundamentals will be altered by the fact that the housing market has panned, and a US slowdown will be underway.
