The fact is that the prices of the forclosed properties are going up because of investors like us are buying and taking advantages of the market situations. The reason is that the lower end properties are affordable and are good for rental biz. Also, the feds is doing whatever they can to slow down the trend of forclosing to save the economy.
The prices of mid/high end homes are still somewhat slugish and unpredicatable. But I'd say it's still a good time to buy if you are looking for a place to live or for long term investment...
Afterall, the housing market is the bottom line of the US economy! The US government can't afford to let the bottom fall out!
