Mike - according to Chris Joye the June data is not seasonally adjusted.
"RP Data-Rismark’s June findings are also impressive because their daily index numbers represent actual changes in dwelling values; that is to say, there has been no “seasonal-adjustment”. We know that the winter months of May through August, and June and July especially, are typically very weak. So in “seasonally-adjusted” terms, the capital gains recorded in June would have been larger again."
