The National Association of Home Builders says this year's estimated 22% increase in single-family housing starts was not a fluke. NAHB predicts the market will continue to come back with a 25% increase in 2013, followed by another 30% increase in 2014. Those upticks would bring the market back to 865,000 units. "We think it will continue to grow from there," says Robert Denk, NAHB senior economist. He predicts that market fundamentals can support 1.4 million single-family housing starts a year, but that won't happen until 2016.
