Data through August 2013, released today by S&P Dow Jones Indices for its S&P/Case-Shiller¹ Home Price Indices, the leading measure of U.S. home prices, showed that the 10-City and 20-City Composites increased 12.8% year-over-year. Compared to July 2013, the annual growth rates accelerated for both Composites and 14 cities.

On a monthly basis, the 10-City and 20-City Composites gained 1.3% in August. Las Vegas led the cities with an increase of 2.9%, its highest since August 2004. Detroit and Los Angeles followed with gains of 2.0%.

In August 2013, the 10- and 20-City Composites posted annual increases of 12.8%.

"The 10-City and 20-City Composites posted a 12.8% annual growth rate," says David M. Blitzer, Chairman of the Index Committee at S&P Dow Jones Indices. "Both Composites showed their highest annual increases since February 2006. All 20 cities reported positive year-over-year returns. Thirteen cities posted double-digit annual gains. Las Vegas and Californiacontinue to impress with year-over-year increases of over 20%. Denver and Phoenix posted 20 consecutive annual increases;Miami and Minneapolis 19. Despite showing 26 consecutive annual gains, Detroit remains the only city below its January 2000index level.

"The monthly percentage changes for the 20-City composite show the peak rate of gain in home prices was last April. Since then home prices continued to rise, but at a slower pace each month. This month 16 cities reported smaller gains in August compared to July. Recent increases in mortgage rates and fewer mortgage applications are two factors in these shifts.

"Denver and Dallas again set new highs. All the other cities remain below their peaks. Boston and Charlotte are the two MSAs closest to their peaks with only 8-9% left to go. Las Vegas is still down 47.1% from its peak level."

As of August 2013, average home prices across the United States are back to their mid-2004 levels. Measured from their June/July 2006 peaks, the peak-to-current decline for both Composites is approximately 20-21%. The recovery from the March 2012 lows is 22.1% and 22.7% for the 10-City and 20-City Composites.

All twenty cities posted monthly gains in August, although most cities showed deceleration compared to July. Las Vegas was at the top of the range at +2.9% and Seattle was at the bottom with a return of +0.5%. Month-over-month, San Francisco has been losing momentum as prices increased 4.9% in April 2013 and 0.9% in August 2013.

Fourteen cities showed year-over-year rate acceleration in August versus last month. Las Vegas was the leader with an annual rate of 29.2%, its highest since March 2005. Denver and San Francisco posted their highest growth rates since August 2001 andMarch 2001, respectively. Although Dallas did not break into double-digit returns, the city posted its highest annual gain since it was first published in January 2000.
