San Diego home prices rose 1 percent in February and were up nearly 20 percent compared to February 2013. The Standard & Poor's Case-Shiller home price indices were released Tuesday. San Diego was one of seven cities among the 20 tracked by S&P to show a monthly price increase. The indices were created by taking the housing prices in 20 large U.S. cities in January 2000, assigning them a value of 100, and tracking their subsequent rise and fall. San Diego's value in February was just shy of 197, reflecting a nearly 97 percent appreciation over the last 15 years. that's the third fastest increase in the country, behind Los Angeles and Washington, D.C. While prices across the 20 markets as a whole were flat in February, compared to January, the annual gain from February 2013 was 12.9 percent. Home prices nationally still have not made it back to 2005 levels, before the housing crisis and recession. he said there is less demand for housing and fewer homes being built, partly because of elevated mortgage interest rates, difficulties in qualifying for loans and concerns about consumer confidence.
