Given a bit of time, people will figure out how Zillow's buying spree works, and figure out how to game it to their own advantage. Perhaps put a fresh coat of paint on an old abandoned house that's about to fall down, list it slightly below neighboring houses, and wait for Zillow's stupid computer to buy it?
