If you say you have a realtor that realtor will receive his commission. Your choice. All the seller for a 3% reduction. If they won't give it then call the realtor and invite him in good luck

When someone says they have an agent looking for houses for them, it usually means that the agent is representing the people who are selling those houses. So, unless they can sell you a listed house, they are not entitled to a commission. If the agent wants get a commission on a FSBO, they need to ask the FSBO owner if they can show the house to you and arrange for a commission from the owner if you buy the house.
