It looks like your question got cut off - but I think you are asking how to price your property. I know this sounds cliche, but get a REALTOR that has good success in your area and listen to their advice. If you really want to sell, you will need to be aggressive in your pricing. Lots of agents are collecting listings these days - don't be swayed by someone who is willing to list high just to make you happy. Go look at your market competition and see what is out there. Don't give any value to "potential" upgrades that you haven't done yet and don't wait for that "perfect buyer".
Talk to a mortgage broker or bank and find out what kind of loans your potential buyers might be able to get for your property. Some banks will loan on manufactured homes, but some will not. The year built might be an issue as well, as will whether the home has undergone "title elimination" and is considered part of the property. If you get these questions answered before you list it, you can make suggestions to potential buyers that might make the property more attractive to them.
When you arrive at a price, ask yourself as objectively as you can if you would pay what you are asking for your own property. If the answer is no, adjust accordingly. If you wouldn't truly pay it, no one else will, either.
Spruce it up, clean it up, get a pre-inspection and fix what you can, give it amazing curb appeal and make it the best thing in it's price range. Then it will be a no-brainer for potential buyers and you will pat yourself on the back all the way to the bank!
Good luck with your sale!
