Today, Standard & Poor’s (S&P) released September 2015 values for its Case-Shiller Home Price Index, which tracks the prices of existing single-family homes in 20 U.S. metro areas. The index in each metropolitan area extends from a base value of 100 in January 2000. For example, Chicago’s September 2015 index value was 132.50 before seasonal adjustment; this translates to a 32.50 percent appreciation since January 2000 for a typical home in the Chicago market.

• All 20 cities tracked and both composite indices showed positive year-over-year returns. In Chicago, the index increased 1.1 percent from 131.03 in September 2014 to 132.50 in September 2015. This was slightly higher than last month’s YOY growth rate of 1.0 percent.
• Chicago was among four cities that experienced decreasing monthly rates of change. Chicago’s September 2015 level decreased by -0.4 percent from the previous month, also falling behind the 10-City and 20-City Composites’ respective +0.2 percent growth rates.
• In a press release, Standard & Poor’s Index Committee Chairman David M. Blitzer said “home prices and housing continue to show strength with home prices rising at more than double the rate of inflation. The general economy appeared to slow slightly earlier in the fall, but is now showing renewed strength.”
