There's a new kid on the search engine block: Zillow. Well, it's sort of a search engine, anyway. It's a database of 65,00,000+ homes and their current market values. Plug an address, street, or neighborhood and the city or zip in and presto! through the magic of Google maps and a proprietary formula (iff they told us they'd have to kill us, I guess) you get instant "zestimates" for a home. It's pretty cool, and loads of fun. Is it accurate? They clain it is, within a 10% margin of error. I plugged our address in, and I'd have to agree with them.
