Questions to ask Buyer's Agent

I am meeting with a buyer’s agent tonight to discuss the possiblity of working with him. I have no idea what to expect. Any feedback on the following questions would be great…

  1. What services should I expect a buyer’s agent to provide.

  2. What questions should I ask this agent?

  3. How much should I trust this agent?

  4. Would you recommend working with an agent for my first purchase?

I have already identified and run the #'s for 8 cash positive properties. Should I discuss these properties with him. For some reason which I can’t justify, I am leary to blindly put my faith in a stranger…I just don’t know what to expect.

Any advice or experiences you would like to share? Thanks…
