Sales of newly built, single-family homes rose 11.1% to a seasonally adjusted annual rate of 300,000 units in March, the U.S. Commerce Department reported on April 25.

The gain partially offsets a large decline that occurred in new-home sales this February, when activity hit a record low due partly to poor weather conditions.

"The fact that new-home sales have regained some of the ground they lost earlier this year is a promising sign at the start of the spring home buying season," said NAHB Chairman Bob Nielsen.

"While potential buyers continue to be extremely cautious, they are starting to take a look around and evaluate their very good options with regard to attractively priced new homes," Nielsen said.

"The March pace of new-home sales more accurately reflects current market conditions than the extremely low pace we saw in the first two months of this year, when unusually poor weather likely kept buyers away," said NAHB Chief Economist David Crowe.

"That said, the average sales pace for the first quarter of 2011 held at about the same level seen for the last half of 2010,” he said.

“A limiting factor is the extremely thin inventory of new homes for sale, which is now at its second-lowest level in history. Builders continue to confront major challenges in obtaining financing to build new homes, and the shortage of new product makes it that much tougher for them to compete with existing homes on the market. At the same time, tighter lending conditions are making it more difficult for qualified buyers to obtain a mortgage."

New-home sales regained lost ground in three out of four regions this March.

Sales rose 66.7% in the Northeast — up from a very low sales pace in the previous month — and climbed 12.9% in the Midwest and 25.9% in the West. Sales were virtually unchanged in the South, falling 0.6%.

The inventory of new homes for sale fell to 183,000 units in March, which is the second-lowest level on record. This represents a 7.3-month supply at the current sales pace.
