I did not give you the thumbs down but I did think your comment was sarcastic. I think you may have received the TDs because you were discussing commissions in a way that could be construed as price fixing. I also don't think that Elizabeth was quoting a 50% co-broke. I have known many Realtors that reduce their commission by a full % if they work both ends.
Or better yet start interviewing agents in your area and list the home.
