Home prices nationwide are up both year over year and month over month, according to a report released today by property analytics company CoreLogic.

The report says home prices, including distressed sales, increased by 6.4 percent in September 2015 compared with September 2014 and increased by 0.6 percent in September 2015 compared with August 2015.

The report projects home prices will increase by 4.7 percent on a year-over-year basis from September 2015 to September 2016, but could dip slightly month over month from September 2015 to October 2015.

Sam Khater, deputy chief economist for CoreLogic, said in a statement that after 10 years of volatility, home prices have been “remarkably stable” for the last 15 months.

“Home price volatility is now back to the long-term trend prior to the boom and bust which is a good barometer of the market’s stability and health,” Khater said.

Anand Nallathambi, president and CEO of CoreLogic, said that while homeowners like to see rising home prices, some markets are becoming overvalued and pose elevated risks to the housing economy.

“More has to be done to expand inventories if we are going to address the emerging affordability crisis, especially in hot markets like California and Colorado,” Nallathambi said.
