The Private Brokerage Advantage
As an independent luxury buyer representative, Régis shares 50% of the buyer-side commission he actually receives on your purchase. Eligible buyers receive that Buyer Commission Share directly at closing to offset closing costs, down payments, or renovations. The figures beside this are illustrative, based on a 3% buyer-broker commission; your share follows the commission offered on the transaction.
