Which of the following actions can a licensed assistant perform?

A licensed assistant can host an open house with the seller's permission because this activity falls within the scope of support roles in real estate. Hosting an open house involves providing information about the property to potential buyers, answering questions, and showcasing the features of the home. This task does not require the assistant to perform licensed activities such as negotiating contracts or providing expert opinions on property values, which would necessitate a more substantial level of licensure and responsibility.

In contrast, drafting legal documents, negotiating contracts, and performing appraisals are all activities that typically require a licensed real estate professional. Drafting legal documents involves creating contracts that may have legal implications, negotiating contracts requires expert knowledge in real estate law and market conditions, and performing appraisals entails a formal assessment of property value, which requires specific training and licensure. Therefore, those actions are beyond the capabilities of a licensed assistant.
