The S&P Case-Shiller 20-city home price index climbed 13.6% year-over-year in October. 

This is the highest level of growth since February 2006. Both the 10-city and 20-city composite indices have been up for seventeen straight months.

"Monthly numbers show we are living on borrowed time and the boom is fading," David M. Blitzer, Chairman of the Index Committee at S&P Dow Jones Indices said in a press release.
