Isn't Sotheby's an Auction House?

Founded in 1976 as a real estate service for clients of Sotheby's auction house, Sotheby's International Realty has sold some of the world's most extraordinary properties. The tools and techniques we have developed to successfully sell grand estates are equally effective for selling fine properties in all price ranges. We post many top sales records around the world each year, yet over half of the listings we sell are priced under $1 million.
