Zillow.com is a sort of Kelley Blue Book for homes. It lets users type in an address and see specs on the home--its valuation, the date and purchase price of the last sale, and data on comparable homes. The site is ad-supported and thus free to the user.
The site offers valuations on more than 40 million of the estimated 85 million single-family homes in the United States, with some data on an additional 20 million homes. It also offers historical value changes for homes in chart form; historical value changes for homes as compared with the surrounding ZIP code, city, state or country; all comparable home sales in an area; and satellite, aerial and parcel views of homes.
Users can also create confidential personal worksheets on individual homes and use a tool that lets them refine the value of a home based on changes or additions to that home, such as a kitchen remodel. The tool calculates the remodel value for the area based on local remodel data and depreciation. And you don't need to worry about your privacy when using it since Zillow.com collects no personal information and makes a guarantee that no one will contact you as a result of using the site. If you're buying or selling a home, it's worth stopping by this page.
