RISMEDIA, October 21, 2010—Nationwide housing starts edged up 0.3% to a seasonally adjusted annual rate of 610,000 units in September, due entirely to a 4.4% gain in the single-family sector, according to U.S. Commerce Department figures. "Builders are cautiously responding to the small improvement they are seeing in interest among potential home buyers," noted Bob Jones, chairman of the National Association of Home Builders (NAHB).
