Trulia typically only allows realtor listings and is a great search site for buyers as well as advertising medium for sellers. If you question the value of a realtor, right now in Wisconsin, the market is so hot, you may be limiting yourself if trying to sell on your own. And this is coming from a realtor that endorses "for sale by owner" or discount listings in which a brokerage allows the seller to perform showings and negotiate a price. At this moment, your best bet is to list and discover the true value of your home, especially if you want to market it in the next 3-6 months. I have other ideas as well in helping a person that doesn't yet trust realtors.
