It is a tough question because when one side is not represented in a transaction it does open up a huge liability for the side represented by a real estate professional or an attorney. Invariably many prefer not to take the risk.
My advice is to offer a competitive commission at the very least for buyers you are attracting. Since you are not paying a listing fee, make sure you price your home BELOW comps, don’t try to be greedy and price it at comps. Make sure the house shows well.
