Imagine cool Google Maps interface + all the data publicly available regarding real property, what do you get - Zillow.com
This is too cool. For example, click here and drill down to 111 Penhurst Pkwy the current residence of former Buffalo Mayor Masiello. All sorts of cool information is available. There's an e-mail option to receive additional data when it becomes available for that current address.
Check out this place right behind the Mayor's house at 152 Lincoln Parkway. Yeah, guess what...it's off the tax rolls! The owner would have paid $37,000 in property taxes, but doesn't...hmmmm...
