Any agent whose brokerage or MLS sends listings to Zillow can put a home on Zillow for free. By doing so, the agent benefits from the visibility their listing receives on the Zillow platform. Listing agents are featured for free on their listing, and their information is always clearly noted on their listing.
Additionally, all real estate agents can create an agent profile for free. Agent profiles are a great way for agents to build their brand, promote their listings, and establish themselves as local experts by showcasing consumer reviews.
