Everyone here has given you some great advice. As a Realtor in Papillion, I know which house is yours, and I'm sorry it hasn't sold. I've been working with Buyers in this price range and I've shown them over 20 homes in the Sarpy County area, and we still haven't seen them all. The market is saturated with homes like yours. My advice is to do something to make your house stand out. Most homes are nice and clean, but nothing grabs a buyer's attention. One thing...maybe a granite countertop, a great deck, an updated bathroom with a whirlpool tub...can be the selling point on a home that is just like every other split entry home on the market.
And... talk with your agent. Print out these responses and show them to him. See if there is anything more that can be done. Maybe flyers at your place of work, church or local organizations would help. The more people see your home for sale, the more chance that someone might know someone who wants to be in your neighborhood.
