Sales of new homes surged in April by the biggest amount in 14 years, but the median price of a new home dropped by the largest amount on record. The mixed signals left no clear picture of whether the worst of the nation’s housing slump is over.

The Commerce Department reported that sales of new single-family homes jumped by 16.2 percent in April to a seasonally adjusted annual rate of 981,000 units. That was far better than the tiny 0.2 percent gain that economists had been expecting.

However, the median price of a new home sold last month fell to $229,100, a record 11.1 percent decline from the previous month. The big price decline indicated that builders are slashing prices in a n effort to move a huge overhang of unsold homes.

The jump in sales was the biggest increase since a 16.4 percent surge in new home sales that occurred in April 1993.

However, analysts cautioned against reading too much into the big gain, especially in light of other surveys showing that builder confidence has sunk in recent months over worries that troubles in the sub-prime mortgage market will further crimp demand in coming months.

The strength in sales was led by a 27.8 percent surge in the South. Sales were also up in the West by 8.5 percent and in the Northeast, where they rose 3.8 percent.

Sales fell in the Midwest, dropping 4 percent.

The drop in median prices in April compared to March was a record one-month decline. If the April sales price was compared to the sales price a year ago, the decline was 10.9 percent, the biggest year-over-year drop since 1970.
