The guy I who is a guest now has his investments and he just lives on the road.

identified a Property Looks very good with demographics

On a larger park, I would recommend a formal cost segregation study for this, but an 8 unit park is too small for that to make sense, so you can also assign a value in the bill of sale to include:Landscaping shrubbery & trees: 35 mature trees approx. 20’ tall each, pool equipment, roads: XXX square yards of asphalt paving, sidewalk and curbing, electrical pedestals, concrete pads, underground utilities for electric, sewer or septic, pool, clubhouse, etc. 

Just needs surveyed and a new plat made for the 5 acre minor subdivisions of each 20 acre lot with 20 foot wide dirt roads going off the main property road to the individual 5 acre parcels.

On a residential street with families, you have STR guests speeding down the road, without regard for where kids may live and play.

Two separate issue here.1) FNMA & LLC’S: FNMA allows transfer of deed to LLC if mortgage originated after June 1, 2016 and original borrower owns a majority interest in the LLC and any 12 months of owner-occupancy is first met. https://servicing-guide.fanniemae.com/THE-SERVICING-GUIDE/Part-D-Providing-Solutions-to-a-Borrower/Subpart-D1-Assisting-the-Borrower-with-Property-Related/Chapter-D1-4-Transfers-of-Ownership/Section-D1-4-1-Information-Relating-to-Transfers-of-Owner/D1-4-1-02-Allowable-Exemptions-Due-to-the-Type-of-Transfer/1041300841/D1-4-1-02-Allowable-Exemptions-Due-to-the-Type-of-Transfer-09-09-2020.htmSo, call your loan servicer to find out if FNMA owns your loan.2) Who Goes Where on a LeaseMost states require a lease to identify the owner of a leased property, whether a person, trust, LLC, IRA, etc.Landlord = Lord of the Land = Owner (in your, case you!)

And when you sell down the road you'll be able to take advantage of the primary residence exemption on the portion you live in. 

@Eric Bauer start by identifying states that have reasonably low property taxes and are landlord friendly.

Once you know their numbers, you know where you offer amount needs to be to meet their needs and still provide you a spread in the deal.Once you know that and know your market (which includes how to accurately and properly identify rehab costs and exit values (after repair values), you can then contract with this "partner" in any number of legal ways.

The more information you can give to your agent and other investors in your network, the better chances you have of identifying and pulling the trigger on a potential deal.
