Today we are answering what we believe is the first question most home buyers, sellers, and the curious ask: "How much is this home really worth?" Zillow.com calculates a valuation (the Zestimate™) that anyone can see — for free — for most homes in the U.S., including yours. Or the one you want to be yours. Or the one you are curious about. Or ours, for that matter. You can refine the value of any home with My Zestimator™, an interactive tool that allows you to enter things you know about a home but we don't. This is just the beginning for Zillow.com. We'll continue adding information and tools for homes, local markets and real estate to make the home buying and selling processes easy and accessible.
