The best thing to do is get yourself buyer's agent to search for homes that are ACTAULY available.
At one time RealtyTrac had a major share of the web based consumer info market. Today they have plenty of competition, so maybe they are charging as a way of making up for loss revenue.
If you want info on a specific property or just want some general info. I would be happy to assist you.
Just shoot me an email with your requested info, or leave me a message on my Truilia Profile
