Pick up a sign for free at our sign shop in Downers Grove. Sign comes with a stake to stick it in the ground.  The sign could also be put in a window or attached to a fence. “For Sale by Owner” signs discourage agents from showing your property. Some agents get confused over whether you are offering a buyer's broker commission when they see an FSBO sign. A professional sign will help with individual buyers as well because it presents a good image.
