The problem with going with a listing agent is that he is going to push as hard as he can for the highest price – since his first loyalty is to his client. You might want to consider using Redfin.com just to have someone on your side of the table….
Personally, if I were going to have representation, I would use SD Realtor – Adam Rappaport. He posts here often and has given a ton of good info over the months and years.
