Editor's note: The following is a guest perspective by Rich Levin, a real estate coach and speaker.
Most agents have little or no specific training in negotiating, though it is a major component to an agent's success.
Negotiating is a skill like any other that is awkward at first and improves with practice. Some of these rules will take some time to implement effectively. Others you will be able to apply immediately. (Some of these rules refer to a situation in which you are presenting and negotiation directly versus through the other agent.)
