Final answer:
The scenario that requires the use of the Licensee Buyout Addendum is when an associate in the brokerage wishes to purchase another associate's listing, due to the potential for a conflict of interest.
Step-by-step explanation:
The use of the Licensee Buyout Addendum may be required in certain real estate transactions where conflicts of interest can arise due to the professional position of one of the parties involved. In the context of the options provided, the scenario that necessitates this addendum is when an associate in the brokerage wishes to purchase another associate's listing. This is because the transaction involves individuals who are both affiliated with the same brokerage, which could potentially result in a conflict of interest that needs to be disclosed and managed through the appropriate addendum.
On the other hand, the first option involving a listing associate's offer to purchase an expired listing does not inherently require the Licensee Buyout Addendum unless there's a specific policy or law stating otherwise. The use of this addendum would also not be relevant where a broker is simply not offering a guarantee to sell a property or when a licensee offers to purchase a property as an inducement for the seller to purchase another, unless it's explicitly required by agency policy or law.
