Agent representation - does anyone care?

I have been wondering if anyone actually cares who represents them in a transaction. In the selling of apartment building it is often one of the biggest pieces of an investors net worth, yet often the agent selected to represent them in the sale is simply a relative or the agent who cold called them the most often. It is amazing to me that when investors are so careful for so long that they default to the easiest or friendliest path when it is time to exit, as if there is no discernable difference between agents.

Maybe the investor could take the time to seek out the most qualified representative. There are too darn few agents in Seattle who put the interests of the client first and who are qualified to understand and deal with many of the difficulties and nuances involved in getting a sale closed. Maybe at least ask for references first.
