There are a few key differences between a real estate agent and a real estate broker that are worth examining before looking at the steps to become them. Both licensed real estate agents and real estate brokers represent sellers and/or buyers of real property and land in negotiations to sell, buy, and manage real estate transactions. (homes, buildings, apartments, etc.). However, a real estate agent must work under a licensed broker in order to represent clients, while real estate brokers can work independently.
