The communication is the really important part of this.
At the outset, it is essential that the client and agent understand and agree on things. How often will we talk, under what circumstances, how will the property be shown, will there be open houses / brochures / muffins, will there be feedback calls, et cetera.
There is no best way. Well, WE all think that WE do it the best way, but, everybody's different.
I want to suggest to that you compile a list of expectations for the agent, call them up, and be straight with them. "Gee, agent, I really thought that you'd be doing . . .," and see what they say.
All the best,
