If tenant comes with agent, who pays the Agent?

[Andres Osorno]

Hello,

I am renting a house and have listed it on Zillow (not directly on MLS). I have been showing the property around, describing it to potential tentants, etc. I will also be reviewing applications, approving/declining tentants, drafting the rental agreement, etc. Today a potential tenant came in with an agent from Berkshire Hathaway realty, wondering if they were to apply and I select them, who would pay for their agent? I didn't post anywhere about any fees being paid to agents, one of the reasons I am doing all the legwork.

Any information/insight is very much appreciated. Thanks,
