Real estate owned by big name pros

[BoyChick]

A while ago, there was a post about a website where you could find what real estate a person owns, by entering their name (and I'm hoping viceversa). While the original post centered around the digs of various pros (like Eli Elezra, Antonio Esfandiari- these are just some of the people I remember mentioned), the site was some sort of official database, with satellite pictures, square footage etc., where you could find any address. I recently fell in love with a house that seems vacant, but has no 'For Sale' or 'For Rent' sign outside, and I would like to try and contact the owner about it. So if anybody can help either by providing a link to the post I'm refering to, or to the site in question, it'd be much appreciated. Thanks.
