L.H.
My house is on the market too right now. I have mine listed with a realtor and have had a lot of traffic. I am not saying this to make you feel badly though. I live in a neighborhood that is really popular and homes have not lost any value. They did sell in an average of a month, now it takes 4 months, with a realtor. Before the market went bad, people could sell on their own, but even then it was much harder.
My point is that the market is bad and slow. I have had 22 showings in three months. I have open houses every other weekend with an average of 8 or nine groups. My realtor does not advertise the open houses but does put signs at both ends of my street. He tells me that houses do not generally sell at open houses because it is mostly neighbors, not really serious buyers who go through them then.
I tried to sell my prior house on my own. Again, in the same neighborhood, but 7 years ago when the market was much better. Many realtors would not show my place because it was not listed with a realtor even though I was willing to co-op as well. I think it is a really tough time to sell, especially without a realtor.
Good luck. My thoughts are with you.
