Mark, Marisa, and Cris take a deep dive into current housing market trends.  They consider the demand and supply drivers that are depressing existing home sales and pushing homebuyers towards new construction.  Along the way, the team deconstructs mortgage rates and provides its best estimate of the nation's housing deficit.  Mark challenges Marisa and Cris to come up with solutions to the housing crisis and wonders if we'll ever experience another sharp increase in foreclosures. Follow Mark Zandi @MarkZandi, Cris deRitis @MiddleWayEcon, and Marisa DiNatale on LinkedIn for additional insight.
