Home prices nationwide, including distressed sales, increased 11.9 percent in June compared to last year, according to a monthly report from real estate data and analytics provider CoreLogic. It was the 16th consecutive month of year-over-year price increases.

On a month-over-month basis, including distressed sales, home prices increased by 1.9 percent in June 2013 compared to May 2013.

"In the first six months of 2013, the U.S. housing market appreciated a remarkable 10 percent," Mark Fleming, chief economist for CoreLogic, said in a statement. "This trend in home price gains is moving at the fastest pace since 1977."

CoreLogic predicts that home prices, including distressed sales, will rise by 12.5 percent on a year-over-year basis from July 2012 and rise by 1.8 percent on a month-over-month basis from June 2013. Nationwide, prices are down about 19 percent from their pre-crash peak, the firm said.
