A broker took an exclusive listing contract on a seller’s home. The seller told the broker the roof leaked, but the broker made no notation on the listing. Later, a buyer made an offer on the property that the seller accepted. The broker lied when the buyer made his/her offer; telling him/her the roof was in good condition. After the buyer took possession, he/she discovered the truth during the first rain. Responsibility for the misrepresentation rests with whom?
