If you use the fee to attract buyers. If your thinking that your going to sell your home at a list price and save the real estate fee, it is not going to happen. There are too many listed homes at great prices, unlike a Sellers market when buyers have to search for homes and will pay top dollar.
There are few buyers at the moment and fewer still who have the knowledge or personality type to enter into such a large investment without the service and advice of an agent. The only tool a "FSBO" has is savings and savings to the buyer large enough to intice them into taking on such a sale.
Take a majority of the fee and reflect it in your asking price and then use the remaining funds to market your home. A sign in the yard is not going to get your home sold.
Your asking price, in the current market it is better to be lower, standout and get buyers in the door then to have a large pad, get offers and then negotiate. With more homes then can be seen most buyers will skip over homes that don't offer a clear value.
