Final answer:
When a licensee has no intention of being a dual agent, her obligation to potential buyers at an open house where she exclusively represents the sellers is to disclose the agency relationship and inform the buyers that she exclusively represents the sellers' interests.
Step-by-step explanation:
When the licensee has no intention of being a dual agent and the sellers want her to exclusively represent them, her obligation to potential buyers looking at the house is to disclose the agency relationship. She must make it clear to the potential buyers that she exclusively represents the sellers and has their best interests in mind. This means she cannot give any advice or information that could benefit the buyers at the sellers' expense.
