[W]hy couldn't you serve as a market-maker for homes at a large scale, especially with the unique insights Zillow could have based on their datasets. Indeed, I believe this is what OpenDoor does. From The Economist article [1], "They [OpenDoor] charge a fee for the services they provide: buying and selling homes immediately, with zero fuss. The quick in-and-out makes them more like marketmakers than property investors, who buy to hold. ... "A former Zillow employee told Business Insider that management had been hellbent on catching up with Opendoor, the front-runner. In order to compete, the employee alleged, the company pushed to offer generous deals to potential clients. It called this “Project Ketchup”. Now it has its own fake blood on its hands."
