Metros see record price declines

Case-Shiller index tracks 20 U.S. cities

A home price index that tracks 20 metro areas showed record annual declines in August, with prices down 16.6 percent from a year ago.

Every city tracked by the Standard & Poor’s/Case-Shiller 20-city Composite Home Price Index saw annual price declines in August, and 13 saw those declines worsen from July. That helped push the index past the previous record 16.3 percent decline in July.
