The Case-Shiller 20-City index showed a sharp decline in prices again in November, dropping by a full percentage point. Nineteen of the twenty cities showed a decline in prices. San Diego was the only city where prices rose, albeit by only 0.1 percent. The 20-city index has fallen at an annual rate of 11.9 percent over the last three months and is down by 1.9 percent year over year.
The sharpest declines were in Atlanta, where prices fell by 2.5 percent in November, and the four Mid-western cities -- Chicago, Cleveland, Detroit and Minneapolis -- all of which had price declines of at least 2.0 percent for the month. The annual rate of price decline over the last three months in Atlanta has been 27.1 percent. It was 23.3 percent in Cleveland, 21.8 percent in Minneapolis, and 21.7 in Detroit and Chicago. These price declines are almost as sharp as the peak months of the housing bust in late 2008 and early 2009.
Several of the markets that had remained reasonably strong through the worst days of the bust are now seeing rapid price declines. Prices fell by 1.0 percent in Boston in November and at a 13.4 percent annual rate over the last three months. In San Francisco, prices dropped by 1.2 percent and have fallen at a 14.8 percent annual rate over the last quarter. In Seattle and Portland, prices dropped by 1.1 percent and 1.6 percent, respectively, in November. The rate of decline in the last three months was 13.4 percent in Seattle and 18.0 percent in Portland.
The price declines continue to be led by the bottom third of the market, which is in a virtual free fall in several cities. Prices for homes in the bottom tier in Atlanta fell by 9.4 percent in November and have fallen at a 69.6 percent annual rate over the last three months. In Minneapolis, prices for bottom-tier homes fell by 1.7 percent in November and dropped at a 40.9 percent annual rate over the last three months. The annual rate of decline for bottom-tier homes over the last three months was 16.3 percent in New York, 21.7 percent in Boston, 28.8 percent in Chicago and 31.8 percent in Portland.
The sharp plunge in prices for homes in the bottom tier is consistent with the notion that the first-time buyers tax credit had been supporting the market. The bottom segment of the market had substantial price increases in most cities in 2009 and held its own in the first half of 2010. However, once the credit ended for homes contracted after April 30th and likely sold after July 1st, prices for this segment of the market went into reverse.
The price declines now showing up for the overall indexes in most cities indicate that the price drop for bottom-tier homes is now having an impact on the prices of more expensive homes. This is predictable, since the sellers of bottom-tier homes are buyers of higher-end homes.
It is worth noting that the NAR data is still showing substantial price declines over this period. Since the mix of homes sold would likely skew the NAR price index upward (fewer low-end homes are being sold, therefore the median and average price would be expected to rise, other things equal), its data is consistent with large price declines.
