Mobile Home 'Park' vs Land with Mobile Homes

[Reid Hanley]

I have found several parcels of land in my area that have multiple Mobile Homes on them, in essence they are mini Mobile Home Parks, but they aren't zoned as mobile home parks.  The mobile homes on all these parcels are owned by the current land owner, so in effect these are Park Owned homes.  My question is, is there an advantage or disadvantage to owning a piece of land with Mobile Homes on them vs owning a piece of land zoned as a mobile home park?  

I believe current zoning would prohibit me from increasing the number of MH's on these parcels, but I would be allowed to maintain the current MHs and continue to rent them out.  Could I sell these MH's to the tenant and charge a lot rent (as in operate it as a Mini MHP)?  I see these as purely cash flow opportunities, although I think offering these homes for sale to the tenants is a great idea.
