This is all part of the scam, and I'm surprised more people can't see through it. Five people walk into a room at closing. There are two agents, a title agent, the seller, and the buyer. Only the buyer brings any money - so it's pretty clear who is paying.

Put it another way - if the seller goes with a lower percentage agent, then the buyer keeps more of the offer price, and should therefore accept a slightly lower offer. This saves the buyer money too.

And you think that's worth 6% of a house that costs hundreds of thousands of dollars? I think that's insane.

This all sounds like a pitch from a realtor.
