To me it never made sense that both buyer and seller agents made the same.
Seller agents have real expenses. Listing in the multiple, photographer, maybe even help in staging. Buyers agents have gas, thats about it. Last few houses I bought, I found them, then brought the agent in who basically opened the door with the MLS key and presented the offer. This was all in the pre-NAR settlement days. Now, if I had a buyers agent, I would negotiate exactly what I expect from them and just pay that.
