I would suggest you list it on a mobile home website. Most real estate websites attract buyers looking to purchase a stick built home. There are websites designed to attract only mobile/manufactured home buyers. This will greatly increase your chance of selling your home. The website I recommend is http://www.mobilehomesell.com. The biggest reason for this recommendation is because they have private buyers who frequently visit the site, but they also have brokers who are always willing to negotiate a quick deal. You might as well look at all your options at once. Just a suggestion. :)
You can list your mobile home on homes.com, frontdoor.com, and forsalebyowner.com if it has been converted to Real Property. I can provide more detailed information if you'd like, feel free to contact me by email or phone, 702-782-3848 firstname.lastname@example.org.
