I came across this article at http://www.cnbc.com/id/34525550?slide=1 which is from a Zillow generated report on the vagaries of real estate markets throughout the U.S. using their "Zestimates". These value shifts are a comparison of 2008 to 2009 figures. Fifteen markets with the most dramatic shifts are highlighted out of 154; 3 good and 12 not so good.
If you are in or near these areas, it may help customers that you're working with to understand what is happening immediately around to them. I find that articles from a news source like CNBC.com contain useful information to pass on.
