Fool.com contributor Morgan Housel chimes in on what could be the first steps of a new housing boom. 

Morgan points out that in the lead up to the housing crisis, we were building about 700,000 more homes than we needed each year, and now we're about 500,000 homes shy of what we should be building each year. 

After a few years of moving through excess inventory, it looks like we could be on track for another boom -- the U.S. economy looks able to support about twice as many homes as we are currently building each year.
