This document discusses Zillow's strategy to transition from a real estate search platform to an iBuying platform operator, noting some challenges it currently faces. It recommends that Zillow focus on becoming an "Amazon of Real Estate" by focusing on customer experience, bringing competitors onto its site, and creating an ecosystem of third-party partners to offer customized real estate products and services at lower costs. This network effects-based approach could allow Zillow to "win" in the iBuying platform space through scale and by completing transactions more seamlessly for customers.
