Realtor says I (the buyer) have to pay part of commission

[Benjamin Pifer]

So I'm interested in buying a home to rent out. Its under 50K and the selling realtor texted me and said her client is only paying 3% of the sales price and that her minimum fee is $1500 and that I have to pay the difference if 3% doesn't cover it. Is this right? What about the buyers agent commission? Is she trying to take advantage of me?

BTW I haven't signed or agreed to anything with her and I don't think she knows I have an agent. I haven't said I do yet.
