Which of the following acts is NOT exempt from requiring a real estate license?

The act described involves a real estate licensee who holds an inactive license attempting to sell property on behalf of someone else, in this case, their neighbor. Under Georgia real estate law, maintaining an active license is essential for any licensed individual who engages in real estate transactions, including assisting others in the sale of property. An inactive license means the individual is not authorized to perform any activities for which a license is required, including the sale of another person's home. Therefore, this activity requires an active real estate license, making it the correct choice for the scenario that is not exempt from licensing requirements.

In contrast, the other options describe situations that involve individuals acting in their personal capacity where a license is unnecessary. For example, managing one's own rental property, selling one's own home, or a spouse selling their partner’s property are all activities where individuals are exempt from needing a real estate license, as they do not involve representation or the sale of someone else's property on a professional basis. Such exemptions are designed to allow individuals to handle their personal real estate transactions without the need for a licensed middleman.
