If a buyer gives a personal check as a deposit but instructs the broker not to cash it until after a specified date, what is the broker's best course of action?

The best course of action for the broker in this situation is to present the offer and inform the seller of the buyer's instructions regarding the deposit check. This approach maintains transparency and professionalism in the transaction.

By presenting the offer, the broker ensures that the seller is aware of the buyer's interest and terms, facilitating a smooth negotiation process. Informing the seller about the buyer’s specific instruction not to cash the check until after a designated date is crucial, as it allows the seller to understand the buyer's financial intentions and plan accordingly. This action adheres to ethical practices in real estate, where communication and transparency are vital for fostering trust between all parties involved in the transaction.

Furthermore, the other options may create issues. Cashing the check immediately could undermine the buyer's instructions and potentially lead to disputes. Returning the check could signal that the offer is not valid, potentially causing the buyer to miss out on the opportunity. Delaying the presentation of the offer until after the specified date could also result in lost opportunities for the buyer or not aligning with the seller’s timeframes. Thus, option B aligns best with professional standards and effective negotiation tactics.
