If you are also looking to advertise on the web, here are a few sites that are free. I agree completely with Pam about using a Realtor. More than 80% of FSBO sellers wind up using an agent and they usually get a better price. The danger in this market is trying by your self, will probably lead to lots of low-ball offers. The longer this process takes, the more you risk from possible negative changes in the market.
