Being able to stand tall and live with your decisions is better than any sale you might make. These are people who will never be satisfied no matter what you do, or what level of service you provide. People tend to know, enjoy, and develop friendships with people who are similar to themselves. Determine who you want your current clients and future prospects to be. Sometimes people view agents as the enemy or as a necessary evil.
Prospects can sometimes play hide the ball with an agent.
I think that open and truthful communication between the agent and the client leads to a successful relationship and transaction. In the end it will lead to successful referrals. Some agents may be offended by this question. But the truth is we are in this business to provide a service and to turn a profit. In my career I entered into a handful of deals annually to help people.
