Joanne is right - it is so important to get on-line exposure so that as many potential buyers as possible view your property. Most buyers search on-line months before they start looking at homes with an agent. When you show your home on the internet, be sure to include LOTS of photos and a virtual tour. Surveys tell us that most buyers want to see more pictures - make sure they are attractive and hi-lite the best features of your home. There are additional sites like fsbo.com and forsalebyowner.com that give you help with this if you really do want to take it on yourself.
You need to price your home appropriately to your local market (to avoid a low appraisal sinking your deal, or underpricing your property) and please consider your personal safety when showing your home to strangers - you will want to pre-qualify them over the phone.
