US home prices rose 4.6 percent in August compared with a year ago, the largest year-over-year increase in more than six years. Prices in New York were up 5.8 percent.

CoreLogic, a private real-estate data provider, also said prices rose 0.3 percent in August from July, the sixth straight monthly gain.

“The housing market’s gains are increasingly geographically diverse, with only six states continuing to show declining prices,” said Mark Fleming, chief economist for CoreLogic.

Those states include New Jersey, where prices fell 1.4 percent.
