Buying additional investment properties without buyers agent?

[Michael Greenberg]

I am a real estate investor, short term rentals (Airbnb), and looking to acquire additional properties in the near term.  I am considering asking the seller's agent to become a transaction broker on the deals I am considering to use as a purchase negotiating tool, e.g. offer less since seller does not have to pay a commission to the buyers agent.  I know what I am looking for, doing my own homework to find the properties I want to potentially buy, and scheduling my own showings with the sellers agent working through the due diligence myself.  Good idea or mistake?
