The town the mobile home community is in has a LARGE percent of tenants vs. home owners (60/40), so I'm wondering if I'm trying to force the issue by selling on contract when the tenants really just want the freedom to rent?

You'll be able to jump on issues quick.

The only issue I have with this theory is that the returns %.

Issues with the property at closing: low water pressure, aging roof, several lights not working, dated interior, water stain under HVAC unit, damaged decking (burn hole & rotting boards), old appliances, holes in drywallAnticipated cost to renovate:  $22500 (includes roof, repiping from old galvanized pipes, renovation of currently empty unit)  The currently occupied unit is TBD on cost, the tenant has been in place for the past 3 years.   

If you are carrying a high note and this is indeed your only investment I do not think there is an issue keeping this in your name. 

He already has his in another property so the seller would have to forgo his entitlement to make is assumable.The real issue with assumable loans right now is the down payment. 

I’m attentive to issues quickly and make quality fixes and updates.

Issue is we have the JV partner and they would like to be part of the ownership if we long term hold.

Is there a timing issue with your state's laws? 

As others have mentioned, the common sources are Furnished Finder and Airbnb longer term stays.
