With the advent of buyer's agency, the only agent working for your best interest is your listing agent. Every other agent is working for the benefit of his/her buyer. Interview potential listing agents as you would an employee. Make sure the agent you hire is a full time experienced agent in your area. Have a clear understanding of the level of service that will be provided from hosting a tour for local brokers, marketing your property and managing the transaction through a successful closing. You're hiring someone to provide very important services for you, so don't hesitate to ask questions. I'll be happy to provide you a list of services you should expect.
