Sales had been expected to fall to an annual pace of 4.45 million units, according to Thomson Reuters.
The median sales price plunged to $165,400, down 15.5 percent from $195,800 a year earlier. That was the second-lowest drop on record.
Prices are down about 28 percent from their peak in July 2006.
