Has all the air gone out of the housing bubble?

Ask the man who spotted the last one:

"If you look at the trend in rents to see where housing prices are headed, you're looking at the right measure," says Yale economist Robert Shiller.

In recent reports, Deutsche Bank demonstrates how steady or even falling rents have pulled down housing prices, to the point where in many markets it costs about the same amount to own as to lease. That's a golden mean that America hasn't seen in almost a decade. The DB research also offers convincing evidence that the wrenching adjustment in housing prices is finished for much of the nation, with a bit more pain to come in selected areas.
