Which of the following is necessary for a person in a corporation participating in mobile home sales?

In the context of mobile home sales within a corporate structure, having the appropriate licensing is critical for compliance with legal standards and regulations. A person participating in mobile home sales must hold a dealer's license, which requires an application and completion of an exam. This ensures that individuals involved in such transactions are knowledgeable about the industry, regulations, and ethical sales practices.

While there may be specific scenarios in which an individual is exempt from licensing requirements—such as working solely as an employee under a licensed dealer or being a limited partner with minimal ownership—these situations do not apply universally. Therefore, obtaining a dealer's license is a necessity for those directly engaged in mobile home sales, emphasizing the importance of regulation in maintaining the integrity of the industry.

Overall, the requirement to apply and pass an exam for a dealer's license underlines the commitment to professional standards and consumer protection within mobile home sales.
