In order to become a real estate agent and legally practice real estate, you must work under a supervising broker. Brokers are licensed by the state to oversee real estate transactions and ensure that real estate salespeople (that's you!) are adhering to the required legal and ethical standards.Think of it as a similar safeguard to how stockbrokers must work at a licensed firm to trade stocks, rather than just winging it on their own. Eventually, you could also apply for a license to become a real estate broker as well, but you will first want to get a few years as an agent under your belt.
Don't expect to waltz in and collect an hourly salary: Most brokerages pay their agents only by commission. In other words, you get paid only when you complete a transaction, and you typically won't receive benefits. Due to this pay structure, brokerages are typically eager to welcome new agents, since it comes at no cost to the company. So be sure to find a brokerage you like, one that is open to taking you on so you can receive some on-the-job training.
