Answer:
a licensed real estate broker
Step-by-step explanation:
A "real estate agent" is a licensed individual who works by buying and selling properties. In order to practice this profession, he needs to associate himself that he's working under a brokerage.
The person can lawfully do his work as a real estate agent, provided that the real estate broker he's working for has a license. If the broker doesn't have a license, then it's considered illegal.
So to speak, the real estate agent functions like a salesperson.
