Home prices falling at record rate in November

The decline in U.S. home values accelerated in November, with prices falling for the third month in a row in all 20 cities tracked by the Case-Shiller home price index released Tuesday by Standard & Poor’s.
For the 20 cities, prices fell a record 2.1% in November. In the past three months, prices fell at an annual rate of 16.2%.

Among those 20 cities, prices have fallen a record 7.7% in the past year. For the original 10-city index, which has a longer history, prices are down a record 8.4% in the past year, exceeding the drop recorded in 1991.
Home prices fell in all 20 cities in November, led by a 3.6% drop in Los Angeles.
The outlook is grim, economists said.

“With supply overhang enormous and mortgage financing tougher to obtain, home prices are going to decline considerably further in the quarters ahead, most likely to a double-digit pace on a year-over-year basis before too long,” wrote Joshua Shapiro, chief economist for MFR Inc.

“We reached another grim milestone in the housing market in November,” said Robert J. Shiller, chief economist at MacroMarkets LLC and one of the developers of the index. He noted that prices fell at a record pace in November in 14 of the 20 cities. In eight of the cities, prices have been falling for more than a year.
