Real Estate commissions cannot be fixed by law, period. You may offer whatever you want – dollar or percentage wise. closer you come to the customary 2 1/2% to 3%, the better chance you will have of making a buyers agent’s list of properties they show their clients when they have to make the choice about which to show. A buyers agent can’t show their clients all the thousands of homes for sale in our markets. But regardless of the amount offered, your home will be seen by active prospective home buyers searching the MLS and REALTOR.com. 80% to 90% of all homes sold accross the country are attributable to the MLS and REALTOR.com.
