Final answer:
Sandra's actions in not disclosing to Tally that she shared the CMA with Sam, and recommending an offer at the CMA price despite Tally's higher listing price, could represent a breach of fiduciary duty and lack of transparency required from a broker in a dual-agency role.
Step-by-step explanation:
Sandra, as a broker, has fiduciary duties to both her seller, Tally, and her buyer, Sam. This creates a dual-agency situation where she is supposed to act in the best interest of both parties. However, by providing the Comparative Market Analysis (CMA) to Sam without Tally's knowledge, Sandra may have breached her duty to Tally. The fact that Sandra recommended Tally accept an offer that is at the CMA-recommended price, despite Tally wishing for a higher sale price, can be construed as Sandra not fulfilling her obligation to seek the highest possible price for her client, which is part of a broker's responsibility to their client.
Tally could argue that Sandra prioritized her own interest of closing an in-house sale and gaining a higher commission over Tally's interest of netting as much as possible from the sale. Furthermore, Sandra's failure to disclose to Tally that she had shared the CMA with Sam could be a violation of the transparency required in an intermediary relationship. Therefore, Sandra may have a difficult time finding a strong defense, as her actions do not align with the best practices and ethical requirements of real estate professionals.
