Sales of newly built, single-family homes in March increased 7.4% to a 724,000 seasonally adjusted annual rate from a revised January number, according to newly released data from the U.S. Department of Housing and Urban Development and the U.S. Census Bureau. The pace of new home sales in March was up 6.0% compared to a year earlier.
