Somtimes I wonder. So many agents get into this business and I notice, even the experienced ones don't really know it. Even the most basic thing, like the Code of Ethics. I am Chairman of a large Association of Realtors in Metro Detroit and I am always being asked for advice on the procuring cause issues, Code violations, etc.. And I ask myself, "How can an agent be in this business and not know the answers to those questions themselves?". I mean, come on, there are local agents in my Association that don't know the difference between our Association and the MLS (ours is separate).
So for all of you out there that are having trouble understanding the Code of Ethics, I have it here for you below. And if you still don't get it, choose the second link, NAR has done a great job translating it for you.
