Looks like you are inquiring about a buyer's agent, either way, here are few questions that you may want to ask. Is the agent a full time or part time agent? How much experience do they have in your search/sale area? Do they have any recent sales in the area? How many sales did they have in 2008? Do they have any testimonials from previous clients? How does their commission split work? Most times we get paid from the list agent, but sometimes there is a difference that may be owed by you. Such as if your agent works on 3% commission, but the list side is only offering 2.5% to the buy side-you may be obligated to pay the difference. Something you should discuss up front, so there are no surprises. Good luck in your search, I'm sure you will find a great agent to help you. If you need me to refer a local professional, let me know. I'll be happy to assist and have someone contact you asap to set up an interview. Good luck!
