> large spread between their buying price and their selling price This is the market I was amazed Zillow didn't get into: the "WE BUY UR HOUSE 4 CASH" market. I'm guessing the volume is too low (few people sell their house for stupid low offers) and advertising costs are too high (those people probably aren't obsessively checking Zillow for their home's value every day). But still, it seems like easy money, that someone far less knowledgeable and talented than them is currently scooping up, that would better insulate them against market turns.
