You certainly could try, but no listing broker will give you the entire commission. They will want to be compensated for having to deal with you as an unrepresented buyer. Since they already have an agreement between them and the seller for the full commission they don’t have much incentive to give you a part of their commission. Clients come to us all the time with stories of losing out on a property because they could not get the seller’s agent to give them any sort of a rebate or discount.
With Buyer’s Advantage, you get a defined amount as your rebate as well as a dedicated, experienced buyer’s broker working on your behalf.
