CoreLogic (Formerly First American) released their Home Price Index Report for April 2010 
“The monthly increase in the HPI shows the lingering effects of the homebuyer tax credit,” said Mark Fleming, chief economist for CoreLogic. “We expect that we will see home prices remain strong through early summer, but in the second half of the year we expect price growth to soften and possibly decline moderately.”
Of the biggest markets, Washington DC best, Chicago worst:
Of the 50 states, Idaho and Illinois show largest YOY decline:
Notes: The index is a compilation of repeat sales transactions going back to the mid-1970s, from CoreLogic’s own property information and its securities and servicing databases covering all 50 states. The index tracks increases and decreases in sales prices for the same homes over time, which provides a more accurate “constant-quality” view of pricing trends than basing analysis on all home sales.
The report is the only major one I am aware of that breaks out distressed properties from actual – I tend to ignore the breakdown since I don’t see these markets as mutually exclusive. In other words, distressed properties compete with non-distressed and by simply removing the distressed properties from the mix, price trends of the non-distressed properties were still impacted by distressed sales.
