I found this graph here. It sure seems to indicate that some housing markets will be in decline for some time to come. Real estate prices tend to correct at a much slower rate than say stock or commodities. This doesn't mean that all real estate prices are falling (Buffalo's are rising).
The question is, will the politicians allow the market to correct and face a short, sharp recession or will they try to prop up prices and keep the country in a long period of stagnation? My guess is the later. We are a society that tries to avoid pain at all costs.
