MLS also lists the rates the house is paying out. ie, the usual rate for selling a house is 6% and 1/2 goes to the selling agent and 1/2 goes to the buying agent. this is outside any kind of other fees you will pay such as closing costs, etc. If you list lower than like 5% on those rates or decide you don't want to pay the buying agent as much, they just wont show your house, even if its perfect for the client.
