Question on Realtor Fees and Broker Fees on HUD

[Greg P.]

Hello all. I bought a property recently and there was a brokers fee that my realtor who was representing me on the buy side said that his broker requires it. Is this standard? I thought realtor/brokers fees are taken out from the seller side only? Lastly, what is the total commission typically that a seller pays. Is 6% standard?

Thank you, Happy Thanksgiving.
