That's the business agents choose to be in. It's better to work to death and make something, versus sitting at home and not making zilch.
Zillow is very smart to focus on agents, and their Zestimate is an ingenious move. What does a home owner do first when she's considering selling? Check out how much the house's worth of course. People making fun of Zestimates miss the point badly. It's a marketing tool first and foremost. Of course it's not accurate. It can't be super accurate and doesn't need to be.
Redfin on the other hand focus on the buyers. That's a terrible mistake. And I still see Glenn go on Bloomberg and CNBC saying it's all a bubble and sellers are getting greedy. Hello? Did you just call me Mr. Homeowner greedy and delusional? How dare you? No business for you!
