Begin by asking someone that you know. Friends, relatives, co-workers, or neighbors who have recently purchased a home can give you a firsthand account and attest to the agent’s professional abilities. Sometimes an agent you contact will refer you to another one who works more closely with buyers and sellers in your neighborhood. Once you have a list of names, interview at least three agents and ask questions about their community knowledge, professional experience, and commitment—some agents work full time; others only work at nights and on the weekends.
