There are occasions when houses are put on the market by auctioneering firms but when they are not sold. In such instances, the vendor may eventually be approached by someone and they may agree to sell it. One must be careful and question whether the auctioneering firm, which has failed to sell the house, should be entitled to reap the benefit of the vendor's capacity to sell the house on his or her own behalf. I raise a question mark about that because it does happen.
