One important way you can tell a good agent from the others is the marketing effort. A caring agent will not only help you get things in order, they will hire a professional marketing company that sends a professional photographer, makes a lovely feature sheet and creates a superior online tour of your home. Expect your home to be advertised in many different mediums, online and in print. Also, expect there to be an open house where people and other agents can tour your home. These things are critical when selling your home.
