Seller/Seller Broker Charging a 3% Buyer Fee on Commercial?

[Darvin Ezell]

I have a Buyer that I am working with to try and finalize my first deal on a commercial property and I have been dealing with the sellers rep. We are negotiating right now but the sellers rep said they are asking for a 3% Buyers Fee? Isn't that the 3% the commission to be paid to the seller, and why would my buyer pay their commission, isnt there seller supposed to pay their commission? Helpful responses appreciated.
