Dave Leonhardt looks at various metrics for home prices and concludes that foreclosure auctions may be the pest metric, because many people are deferring putting their house on the market, hoping for prices to increase.

Auctions indicate that house prices still have a way to fall, as I agree, and Dean Baker has the graph shown to indicate that prices are still above historical norms.

I actually expect a measure of overshoot. so if you assume that prices will head down to about 80 before rebounding, and the the path is a straight line, you are looking at a real estate turn around somewhere in 2011-2012, based on my imprecise eye.
