Who among the following is required to have a real estate license to sell property?

A licensed builder is required to have a real estate license to sell property, as their job often includes selling properties they have constructed or renovated. Even though licensed builders have extensive knowledge and experience in construction, that does not exempt them from the real estate licensing requirements when it comes to selling real estate. In the state of Michigan, engaging in real estate transactions—whether it's representing oneself or others—requires a real estate license to ensure compliance with state regulations and to protect consumers.

On the other hand, a certified appraiser focuses primarily on estimating property values and does not engage in the buying or selling of properties, thus not needing a real estate license. A property management company may manage properties but typically involves leasing and renting rather than selling. A real estate investor may buy and sell real estate but generally does not act as an agent for other sellers unless they hold an appropriate license. Each of these roles has distinct functions in the real estate market, which is why only certain professionals, like licensed builders in this scenario, are required to have a real estate license for selling properties.
