Turnkey marketers don't represent buyers. Why?

[James O.]

I was talking to a turnkey company and I read in the fine prints that they do not represent buyers. I always thought of them as buyer agents in a turnkey purchase. Is this because they want to avoid legal issues? Or not take on duty as a fiduciary?

Also, how much do the turnkey marketers get paid? Do they charge sellers 3% for the "representing" buy side?
