But I often wonder why states spend so much time on making sure these people are licensed when any joe schmoe can sell his house himself without an agent.
For example, in NJ, it seems to get your real estate license you can either become a salesperson (who works for a broker) or a broker. You have to go to school and accumulate anywhere from 90-150 hours of classwork, take tests, then work for a real estate outfit, etc.
That seems like a lot of work to make sure that a person is competent in this field when any idiot can list and attempt to sell his or her house themselves (granted, it may be easier and less painful with an agent).
