Then how am I suppose to sell my house?
Brokers Agent - Plain and simple. If you are thinking about selling your home and you are going to list it on the MLS, then you need to have the agent have the CORRECT wording on the contract.
If Mr. Seller hires Broker Bob to sell his home then the listing agent is working for Mr. Seller BUT, lets say Broker Bob lists the home on MLS and still wants all the agents to represent Mr. Seller, he can do so, but not as a SUB-AGENT.
By wording the contract to have all agents show your home as a BROKERS AGENT, what the seller is doing is removing themselves from the vicarious liability of any other agents who bring buyers into his home.
