Zillow's CEO says the Real Estate market is not good and going to get worse before it gets better. First, he's talking about the national market and second, As a real estate professional in Downtown Phoenix, Zillow's estimated property values for my market are ALWAYS way off from reality. I don't know where they get their numbers, but I often have clients counting on their numbers, then I prove to them that Zillow numbers are wrong. http://money.cnn.com/video/pf/2011/12/18/ctd_zillow_housing.fortune/?iid=HP_LN
