When we sold our house in New York, they charged us a fee of 7% if they listed and sold it. But they said if we got our own buyer, we would pay only 2.5%. So the very first day and before the sign went up, my husband was painting in the entry way. A man came to the door and said he saw that he was painting and wanted to know if we would be selling. He said he grew up in the house and wanted to buy it. The house was sold for 240,000 when we had only been in the house for a year. God brought us the buyer and we only got out of the house without paying out of pocket because of that deal.
If you type FISBO resources into google, you should find quite a bit of help. There are websites that help you list it yourself and companies that put together packages to get you started and do open houses. I would not do it without a lawyer though. It's too easy for the new owners to come back on you if anything breaks down very quickly.
