Rebecca and her husband planned to invest between $250,000 to $300,000 in an income property. Rebecca told her husband's brother, Graham who was a real estate agent, about their plans. Graham found them a property that was listed for $299,000. Graham presented an offer signed by Rebecca using her maiden name. The sellers accepted a lower offer of $285,000. Before closing the sellers found out that the purchasers were related to the agent and refused to close. Is there anything wrong with what Graham had done? Why or why not?
