MLS makes a huge difference, Anthony. It gets your house not only in front of the 600+ local agents, but it gets it on sites like Trulia and Zillow. It puts your house in storefront window, which is particularly valuable in a town like Woodstock with all the visitors who spend time dreaming of getting their own place in the Catskills.
Pick an agent who will keep in touch with you, regularly update you on what they're doing to market your house, and who will advocate for you when you get an offer - which you will. Price it right and things are selling.
