REX attempts to save you money on commission by eliminating the buyer's agent fee. It markets your home directly to buyers using digital ads, instead of posting it on the multiple listing service (MLS). If REX finds you a buyer who isn't using a realtor, you won't be responsible for buyer's agent commission. But, since nearly 90% of buyers work with a realtor, this approach is a HUGE gamble. Find better ways to save on real estate commission.
