You only pay the flat fee at time of listing. You will pay the buyer's agent commission that you have decided on in your listing contract at closing if there is a Buyer's agent involved in the sale. The recommended commission is at least 2.5%. If you sell the home yourself no other fees are due at closing.
Due to Louisiana's Minimum service requirement we take a small percentage from the above commission. (.125% above $200,000, .25% from $100,000 to $199,999, .375% from $50,000 to $99,999.
