I have a situation where I reached out to the seller of a listing and she said that she can't show the house unless we have signed a buyers agreement. I said I was concerned that the seller might not allow dual agency and the realtor said they were ok with it. I asked how the commission split on that worked because it my area 6% seller commission with 3% commission going to the buyer is common. She said she doesn't get paid anymore if she does dual agency. She said she can setup the broker agreement for just this one property. Does this sound legit?
