Redfin is a provider of real estate search and brokerage services through a combination of real estate web platforms accessible to agents. It represents people buying and selling homes and features all of the broker-listed homes for sale, as well as for-sale-by-owner properties. Its real estate agents work with the company's team of engineers to create tools that make the buying and selling process easier. On their site, Redfin combines MLS listing information with historical data into a single map. Customers can search for homes by neighborhood, city, zip code, MLS number or school zone, and can refine results using detailed parameters like price and number of beds or baths. The company was founded in 2004 by David Eraker, Michael Dougherty, and Dave Selinger, and is based in Seattle, Washington.Something looks off?
