Real estate agents are a lot like doctors and tattoo artists. You do not really want to rely solely on the Yellow Pages in order to find one. There are a lot of great agents out there and a few bad apples of course. Some other ideas on finding the best are to ask your friends for referrals and also take notice on which agents hold the monopoly on "For Sale" signs in the neighborhoods you are considering buying in. While not the only litmus test to use, it is a good indicator of who has been very successful in your area.
