Home prices in March were 10.5% higher than a year ago -- and a bit more if distressed sales weren't counted, says market researcher CoreLogic.
The overall change was the biggest year-over-year jump in seven years and the 13th straight month for home price gains.
"The pace of appreciation has been accelerating throughout 2012 and so far in 2013," says Mark Fleming, CoreLogic chief economist.
For the month, home prices increased 1.9% in March from February, CoreLogic says.
Excluding distressed sales, which are short sales and foreclosures, home prices were up 10.7% year over year.
Price gains will slow slightly in April, CoreLogic says. It predicts prices will rise 1.3% month to month and be 9.6% higher than a year ago.
But, excluding distressed sales, it says April prices will jump 12% year over year.
Different home price indexes frequently come up with different results, but the trend is clear.
Last week, the Standard & Poor's Case-Shiller index of 20 cities showed February prices up 9.3% year-over-year.
Contributing to higher prices is rising demand among investors and home buyers for a limited supply of homes for sale, CoreLogic says. Fewer foreclosures and other distressed homes in the market can also inflate price changes.
Including distressed sales, the five states with the highest home price appreciation in March vs. March 2012 were Nevada, 22%; California, 17%; Arizona, 17%; Idaho, 15%; and Oregon, 14%, CoreLogic says.
Prices were lower year over year in only four states: Delaware, down 3.7%; Alabama, down 3.1%; Illinois, which dropped 1.8%; and West Virginia, down 0.3%.
