popular "For Sale By Owner site states that 80% of people that try to sell their home on their own, will eventually use a Realtor. That means that 20% where either successful in selling FSBO or just gave up.  That’s because it is not easy to sell your home alone. 

Let’s consider the the buyer’s view point.  When someone is moving from one city to the next, most people do not look at “For Sale by Owner” sites. One reason is a lack of a National FSBO network,,,  so, where do you go?. Realtors have an international network.. It will show you most EVERY home that is listed by a Realtor in the united states. And from a Buyer's perspective, using a Realtor does not cost them anything.
