Realtor.com should be the first stop for home buyers, since it provides the best search options and the most listings of any site—fitting, since it's the official site of the National Association of Realtors. It's the only site in our roundup that lets you jump directly to an advanced search, where you can specify detailed house and lot requirements. The search results page shows which listings have multiple pictures or virtual tours. Also, Realtor.com lets you call up a map with the locations of multiple homes shown at once. It also contains apartment-finding and home-finance links.
