WASHINGTON — Sales of existing homes plunged far more than expected last month as buyers recoiled from October's financial wreckage on Wall Street. The median sales price fell by the largest amount on record.

The National Association of Realtors said today existing home sales fell 8.6 percent to an annual rate of 4.49 million in November, from a downwardly revised pace of 4.91 million in October.

Sales had been expected to fall to a pace of 4.9 million units, according to Thomson Reuters.

The median sales price plunged 13.2 percent in November to $181,300, from $208,000 a year ago. That was the lowest price since February 2004, the biggest year-over-year drop on records going back to 1968 and most likely the biggest drop since the Great Depression.
