Real Estate Agent
A real estate agent is a person licensed to negotiate and transact the sale of real estate on behalf of the property owner. A real estate agent must pass a certification course and state examination which covers the legal aspects of real property, and must pass a background check in order to become licensed. He or she must also satisfy a certain number of hours of additional training each year in order to maintain teh real estate agent license. Typically, to avoid conflicts of interest, buyers and sellers will each have their own real estate agents. Each agent charges a commission for his or her services (a small percentage of the sale price).
Real estate agents are usually very clever in their vocabulary and very hospitable, the job of a real estate agent requires it of them. Like any other salesman, they have to sell their product well, because they're going to be getting a commission of the sale if they can make it. So to be friendly and courteous is an essential part of real estate. It also helps to be well groomed, because a customer not only wants a beautiful house, but someone who is well presented to help them.
