When you close the door, escorting the agent out the door, ask yourself, "Do I trust that person to represent the sale of my home?"
While experience is important and demonstrated knowledge of the local values of homes, you cannot manufacture trust. As a homeowner, you are in control of the listing and sale of your home. You need to find an agent that not only is able to answer buyer questions about your home, town/city and neighborhood, but someone who will reflect the manner in which you do business.
Do they return messages and calls promptly? Consistently hit deadlines? Able to craft and tell a story of your home to entice buyers?
Those are the questions you should be able to answer when finishing a listing appointment with an agent. If any of those answers are no, keep shopping.
