September’s 20-City Housing Market Index from Case-Shiller showed signs that rapidly rising home prices in some metro areas may be losing momentum. San Francisco, California, posted a month-to-month reading of -0.40 percent and a year-over-year reading of 5.70 percent. Home prices stayed flat in Seattle Washington from August to September, but posted the highest home price gain of 11.00 percent year-over-year. Slowing home price growth in high-demand areas suggest that affordability concerns are impacting rapid gains in home prices seen in recent years.

Case-Shiller’s National Home Price Index achieved its highest gain with a reading of 5.50 percent as compared to August’s reading of 5.10 percent.

Denver, Colorado rounded out the top three cities in the 20-City Home Price Index with a year-over-year growth rate of 8.70 percent. September was the eighth consecutive month that the top three cities held their places in the 20-City Index. Case-Shiller’s 20-City Home Price Index posted a year-over- year gain of 5.10 percent.

September Home Prices Cap Recovery, Usher in New Progress for Housing Market

According to David M. Blitzer, Chairman of S&P Dow Jones Index Committee, September’s record national reading for home prices marks a transition from housing recovery to “the hoped for start of a new advance.” Mr. Blitzer cited recent data on sales of new and pre-owned homes and said that housing starts reached a post-recession peak.

September’s peak in national home prices was 0.10 percent above the pre-recession peak set in 2006. Adjusted for inflation, the September peak remains approximately 16 percent below the pre-recession peak. During the recession, national home prices reached a trough that was 27 percent lower than Case-Shiller’s September reading. Analysts expressed some caution and noted headwinds to housing markets including slower-than-normal rates of homes construction, higher mortgage rates and strict mortgage approval requirements.
