It does not affect you as the seller. The Sage Buyer Refund is paid to a Sage buyer out of the BAC that you agree upon when you fill out the paperwork with the Sage MLS Listing Service Provider. Say you agree to a 3.0% Buyer's Agent Commission (BAC), which is paid to the buyer's realtor at closing. You, as a Sage Seller, still pay your normal 3.0% BAC, and then the Sage Buyer's Refund is pulled out of this BAC to refund the Sage Buyer at closing. Outside of the standard BAC that you agree to when you sell your house (which is standard regardless if you sell through Sage or a standard real estate listing agent), no additional costs are put on you as a seller. Both you, the Sage Seller, and the Sage Buyer buying your house receive savings by using Sage for this house selling transaction.
