Zillow is one of the largest real estate marketplaces in the United States. It lists homes for sale and rent, often with photos, floor plans, and detailed property information. The site also provides Zestimates, which are automated estimates of a home's market value based on public data and recent sales. For anyone buying, selling, or just curious about the market, it's a convenient way to browse listings and compare neighborhoods.

Beyond listings, Zillow publishes market trends, mortgage rates, and research reports. You can set up alerts for new listings and save searches. The Zestimate is not an appraisal and can be off in areas with few comparable sales, but it's a useful starting point. The site also connects buyers with real estate agents and mortgage lenders. It has become a default tool for American home buyers and renters.
