Builder confidence in the market for newly-built single-family homes slipped two points in July to a level of 64 from a downwardly revised June reading on the National Association of Home Builders/Wells Fargo Housing Market Index (HMI). It is the lowest reading since November 2016.

"Our members are telling us they are growing increasingly concerned over rising material prices, particularly lumber," said NAHB Chairman Granger MacDonald, a home builder and developer from Kerrville, Texas. "This is hurting housing affordability even as consumer interest in the new-home market remains strong."

"The HMI measure of current sales conditions has been at 70 or higher for eight straight months, indicating strong demand for new homes," said NAHB Chief Economist Robert Dietz. "However, builders will need to manage some increasing supply-side costs to keep home prices competitive."
