<i>Additionally it may be the case that the buyer&#x27;s agent purposely withheld a buyer, hoping to low-ball the seller, assign the purchase to themselves, and then sell the property for an offer that they could have brought to the seller in the first place.</i><p>If the buyer&#x27;s agent is acting on behalf of the buyer, they were under no obligation (legal certainly, nor ethical or moral, IMO) to bring that higher offer to the seller. (Real estate law and practices are hyper local; around here [MA, USA], a &quot;buyer&#x27;s agent&quot; owes a fiduciary obligation only to the buyer and is allowed (and in fact would be required) to not disclose the presence of this other potential offer as by the &quot;undivided loyalty&quot; clause, they are &quot;prohibited from advancing any interests adverse to the principal&#x27;s [read: buyer&#x27;s] interest or conducting the principal&#x27;s business in such a way as to benefit a customer, a subagent, the agent or any other party to the detriment of the principal&#x27;s interest.&quot; In other areas, that might not be the case.)<p>In that case, it is the <i>listing&#x2F;selling</i> agent&#x27;s responsibility to advise their client (the seller) that the offer is too low and they should wait longer.
