The Case-Shiller index of San Diego home prices dropped for all three price tiers in August. Prices by this measure declined .6 percent for the low-priced tier, .5 percent for the middle tier, .3 percent for the high tier, and .2 percent for the aggregate index.
On a seasonally-adjusted basis, which takes account of typical August strength, the decline was more pronounced, with prices down 1.1 percent for the low tier, .5 percent for the middle and high tiers, and .4 percent for the overall index. The chart of the seasonally-adjusted numbers gives a better idea of the underlying trend, which has been slowly but steadily down since the big pop into the stimulus laden spring and summer of 2010.
