Single-family home prices in Orange County increased 22.9 percent in July, the 14th consecutive month of rising prices, according to Irvine-based housing tracker CoreLogic.

July saw the biggest percentage gain in CoreLogic’s records since prices stopped falling in May 2012.

CoreLogic is the third market tracker to report double-digit home price gains in the county for July. DataQuick reported earlier that the median price of a single-family home rose 18.6 percent in July, while the California Association of Realtor pegged the increase at 22.5 percent.

Nationwide, home prices increased for a 17th consecutive month in July, rising 12.4 percent from a year earlier, CoreLogic reported.

U.S. single-family home prices now are within 18 percent of their peak levels reached in April of 2006.

In California as a whole, home prices increased 23.2 percent, the second highest among states.

Prices were up 22.6 percent in Los Angeles County and 22.5 percent in the Inland Empire.

“Home prices continued to surge in July,” said CoreLogic Chief Economist Mark Fleming.

But Fleming predicted that price growth will slow in the second half of the year “as seasonal demand wanes and higher mortgage rates have a marginal impact on home purchase demand.”
