Sales of new homes rose in April for the first time in six months although the unexpected increase still left activity near the lowest level in 17 years.

The Commerce Department reported Tuesday that sales of new homes rose 3.3 percent in April to a seasonally adjusted annual rate of 526,000 units.

But the government revised March activity lower to show an even bigger drop of 11 percent to an annual rate of 509,000, which was the weakest pace for sales since April 1991. The Commerce report showed that the median price of a new home sold in April rose to $246,100 in April, up 1.5 percent from April 2007.
