The objection is legitimate to that person, no matter how ridiculous it may sound. He feels it is legitimate, so it is legitimate. Interrupting can cause the seller or buyer to become irritated with you. It may not matter how well you handle the objection if you interrupt him. Your mental approach to an objection will determine your success or failure.
Most agents dread hearing an objection, but most objections result from one of two situations.
The other occurrence of objections is because your presentation was not good enough. You did not convey the confidence that you are the person for the seller to hire for the sale of his home. You did not make a convincing enough presentation for the buyer to purchase the home you showed him. The clients' desire to work with you is a natural ending to a good presentation. If the presentation is weak, the objections will flow like a river.
