Home prices continued to fall in November, according to the latest S&P/Case-Shiller Home Prices Indexes, which survey prices in 10 and 20 different metropolitan areas across the country.

The 10-City Composite index matched the previous month's record 19.1% drop in home prices, while the 20-City Composite benchmark set a new low by dropping 18.2% in November 2008.

The results represented the 28th consecutive month both indexes have declined. The swoon started in August 2006, according to S&P's David Blitzer. "The freefall in residential real estate continued through November 2008," he said in a statement.

Every region was down at least 1% in the month, and eight set new records, with Phoenix and Las Vegas the worst hit. Those were down between 3.3% and 3.4% in the month. 

Even worse, all metro areas showed losses for the third straight month. Eight areas hit new lows—Atlanta, Boston, Charlotte, Chicago, Dallas, New York, Portland and Seattle.

When yearly comparisons were made, two metro areas, Dallas and Denver, seemed to hold up the best. Both kept losses in single digits, with Dallas down 3.3% and Denver falling 4.3% compared with November 2007 monthly prices.

S&P did note, however, that Charlotte (-1.9%) reported its third straight record monthly fall.

Meanwhile, Denver and Cleveland did the best in November 2008, dropping 1.1% and 1.2%, respectively.
