Commercial real estate agents assist business owners in the buying or selling of commercial properties, as well as managing lease agreements for tenants in commercial properties. The purchase and sale of commercial properties take much longer than residential properties; some transactions may last as long as six months, and can even take longer. Most commercial real estate businesses are large operations that include many agents, analysts, and other financial and building experts. As a commercial real estate agent, you are often on the move, networking with potential clients, inspecting sites, doing public records research, and consulting with lawyers about legal issues, such as zoning and permitting. You may also follow up with tenants concerning lease issues and renewal contracts.
