According to the U.S. Department of Housing and Urban Development and the U.S. Census Bureau, sales of newly built, single-family homes in September 2017 rose 18.9 percent to a seasonally adjusted annual rate of 667,000 units from an upwardly revised August reading. This is the highest sales rate since October 2007. Year to date, new home sales are 8.6 percent above their level over the same period last year.

"The September sales numbers show that there is solid, growing demand for new home construction," said Granger MacDonald, chairman of the National Association of Home Builders. "However, builders need to continue to monitor rising construction costs to keep houses affordably priced."

"New home sales have bounced back from a few soft months and have returned to the strong growth trend we saw earlier this year," said NAHB Chief Economist Robert Dietz. "As existing home inventory remains tight, we can expect new homes sales to continue to make gains in the months ahead."

The inventory of new homes for sale was 279,000 in September, which is a 5.0-month supply at the current sales pace.

New home sales increased in all four regions. Sales rose 33.3 percent in the Northeast, 25.8 percent in the South, 10.6 percent in the Midwest and 2.9 percent in the West.
