There's a reason that 85% of homes sell using a real estate agent. As a homeowner, you simply can't compete with the marketing resources of a real estate company.... they're blasting their listings out to hundreds of sites, both nationally and internationally. If you really want to sell, you need to get an agent. They may tell you some things you don't want to hear, particularly about what a reasonable price for the home may be. If you're serious, I'd be happy to give you a referral for an agent in your area.
