Housing has slowed to the point where demand is again outstripping supply, says Metrostudy founder Mike Castleman.

Metrostudy, which researches the housing industry, says demand is forcing up prices in some markets, including Washington, D.C. and Indianapolis, but it remains stagnant in Houston, Naples, Fla., Charlotte, and Denver.

Overall, Metrostudy and Castleman believe the worst is over. The good news is that builders will need to build a lot more houses than last year to keep up with demand. That will help the economy by creating jobs, Castleman says.
