It is extremly important to post your home on MLS. Most buyers will be working with a Realtor and all of the listing sent over are typically generated from MLS. Not to mention that most MLS's are syndicated to several other sites giving you great exposure. if you are not interested in listing with a local professional you can visit sites that will simply input the home into the local MLS for you for a flat fee. This is considered a limited liability listing and all negotiations would be handled with you directly. I hope this helps!
