A real estate agent is contacted by a potential buyer whose financial interest is questionable, but who needs to write an offer. The agent should:

Writing the offer on a promissory note does not address the underlying concern of the buyer's questionable financial interest. A promissory note is typically used for loans or debts, and it would not resolve the issue of the buyer's ability to proceed with the purchase. This choice could further complicate the transaction without ensuring the seller's protection.

While requesting a high earnest money payment might seem like a way to demonstrate the buyer's seriousness, it does not guarantee that the buyer can follow through with the purchase. If the buyer’s financial situation is questionable, a high earnest money deposit may not be a reliable indicator of their ability to close the deal.

Referring remuneration to the seller does not effectively address the issue of the buyer's questionable financial interest. This choice may also lead to conflicts of interest and could undermine the agent's fiduciary duty to the seller, as the agent should ensure that all offers are legitimate and financially sound.
