Final answer:
In an intermediary brokerage transaction, it is prohibited to disclose confidential information or that a buyer or seller is willing to accept a different price than the one stated, as it violates fairness and confidentiality.
Step-by-step explanation:
Among the practices that are prohibited in an intermediary brokerage transaction, the following instances can lead to breaches of trust and ethical violations:
- Disclosing to the buyer that the seller will accept an offer below the asking price
- Disclosing to the seller that the buyer is willing to pay more than the asking price
- Disclosing confidential information about either party
All of the above practices undermine the principles of fairness and confidentiality that are foundational to the role of an intermediary. The responsibilities of an intermediary include maintaining impartiality and ensuring that both parties in the transaction are treated with fairness and equity. Violating these responsibilities by disclosing confidential information or manipulating the negotiation process is not allowed.
