It's fairly common for people to snap up multiple land home deals in close proximity to each other and then bundle them together to call it a MHP. If the homes are a couple miles from each other then these are just packaged land home deals. You won't get the economy of scale for mowing, tree trimming, etc as your laborers have to pack up their gear and go to each property - so naturally your expense ratio will be higher.
There are a lot of threads about the risks and benefits of small Parks and won't open that discussion back up. However, the concept of lot renting in a neighborhood of mobile homes where both neighbors next door are the land owners can be a tough sell, and may seem like trickery to the purchaser.
I see the best use for a deal like this is to fix up the homes and sell them individually with the land as an owner financed transaction. I have done this where the home has surrendered the title to the land on a permanent foundation (e.g. hitch and axles removed) and everything is real property. You still have to go through the Dodd Frank hoops.
There are a number of ways to make it work, but this specific scenario is not an MHP in any form.
