Some things in writing are good, and others not so much. Every agent is required to present you with a disclosure of who they are representing, I give no points for that. A second thing many agents will have you sign is an exclusive agreement tying you to that agent for a period of time. Exclusive agreements are good for the agent, but I do not believe for the customer. Most agents use them, there is nothing unethical about them, but if the agent doesn't live up to your expectations, you are pretty much stuck with them until the agreement runs out. I think you should be more concerned about getting an agent that you are comfortable with and develop a rapport. You should also pick their brain as all agents aren't created equal. Hopefully you are going with a buyer's agent and not a broker's agent, then they can fully advise you and negotiate for you. Good luck, but don't rush into anything, the wrong agent will just waste your time.
