Actually zillow does show a huge cluster of homes for sale up to 48 million.A look at the map is impressive with red dots all over the area where celebs might live.Maybe there is something to it hard to say.Although is could be just the bad economy who knows.
Suspect the validity of any listings on there. They will leave up a host of off market and sold listings just to keep trolling viewers personal data for contact info. I learned that the best way to check on those is just direct call the lister/agent for something of interest you find there.
