Selling my home - What is fair to ask of listing agents

[Jim Vinh]

I am looking for a listing agent to sell my house next week. Is it fair or common to ask if the agent will represent the seller side only? I believe most agents would like to represent both selling and buying sides since it will mean more commission $, but I can see a conflict of interest there. A listing agent would favor offers from buyers that they also represent, wouldn't they? Thanks in advance for all comments.
