The best route would be to contact a real estate agent (I know, you saw that coming I'm sure.) However, an agent can advise you on the entire process, manage the details, and help you to avoid costly mistakes and legal pitfalls.
If you are wondering how to list your home for sell "by owner". There's really not much to it. But, if this is the case, doesn't the fact that you are not sure how to go about it, suggest the need for professional assistance such as that that an agent would provide?
