The numbers: Builder confidence in the market for newly built single-family homes rose two points to a level of 70 in May, according to the National Association of Home Builders/Wells Fargo housing market index released Tuesday.
The Econoday-compiled consensus was for a 69 reading.
April's reading was downwardly revised a point to 68. Any number over 50 indicates that more builders view conditions as good than poor.
What happened: The component for current sales conditions rose while those for buyer traffic and expectations in the next six months were unchanged.
The big picture: Builders are confident, at a time of low unemployment, a shortage of housing inventory and fairly low mortgage rates.
Rising lumber and labor prices remain a concern, however.
What they're saying: "The solid May report shows that builders are buoyed by growing consumer demand for single-family homes," said NAHB Chairman Randy Noel, a custom home builder from LaPlace, La. "However, the record-high cost of lumber is hurting builders' bottom lines and making it more difficult to produce competitively priced houses for newcomers to the market."
