Dr. Mark Dotzour, chief economist at TX A&M Real Estate Center in College Station.  Real estate construction is growing again finally, more people are at work and 5 years of pent-up demand for housing & commercial properties + Americans now have credit capacity again.  For years, people have been talking about how the housing market is aheadwind against economic recovery.  Now turning into a tailwind.  Dotzour said some of the starts will still be constrained by labor shortage, mortgage loan underwriting and a further increase in construction costs.
