I've always used a real estate agent. They are professionals, and know what documents you need, what you must tell the buyers, etc.

They can make flyers, web sites, hold open houses, and do it in a non-prejudiced manner. I would hate to show someone my house and have them criticize the wall color, or the decor. Some people don't mind doing it, but I won't.

The last place I sold was 5% commission if he had to split, or 4% if he sold it himself.

Commissions are negotiable, and in the area we were in, they were taking 5% because the sales price was over $450,000. California in the boom days.

Good luck to you.
