In Delaware, managing one’s own investment property does not require a license because property owners have the right to oversee their own real estate investments without needing to be licensed as real estate professionals. This includes tasks such as collecting rents, managing tenants, and maintaining the property. This provision is in place to allow individuals the freedom to manage their personal investments without the administrative burden of licensing requirements.
On the other hand, representing buyers and advertising properties are activities that typically involve interacting with the public or other parties in a professional capacity, which is why they necessitate a real estate license. Neglecting duties, while it sounds indicative of a lack of action, does not have a bearing on whether an activity needs a license; rather, it's a behavioral aspect that could lead to professional repercussions for licensed individuals.
