Part-time real estate agents are agents that spend less than 40 hours per week buying and selling residential and commercial property. As a part-time professional in the field, you may not make as much of a salary as full-time real estate agents, but your schedule is much more flexible. Part-time realtors work alongside buyers, homeowners, brokers, and other clients to facilitate the exchange of physical property. Your duties can include sales, open houses, online marketing, and cold calling. With the proper qualifications, a part-time real estate agent can work anywhere from 21 to 39 hours each week.
