If I am out with buyers for months on end, I am working for them. However, in our state, unless you have a contract (Buyer Agency), you are automatically a subagent of the seller. I don't want to represent the seller. When I explain what my limitations are as a subagent of the seller, they understand and are more than happy to sign. There really is no good reason for them not to unless they just don't care to be tied down to one agent in which case, I don't care to be tied down to them.
