if so what have you seen recently for each arrangement?

She’s technically an agent, we have our own arrangement, but definitely worth at least reaching out to.

Hey BP,Looking to make this a sounding board for inspiration for how others have partnership arrangements.

(A) A landlord who is a party to a rental agreement shall do all of the following:(1) Comply with the requirements of all applicable building, housing, health, and safety codes that materially affect health and safety;(2) Make all repairs and do whatever is reasonably necessary to put and keep the premises in a fit and habitable condition;(3) Keep all common areas of the premises in a safe and sanitary condition;(4) Maintain in good and safe working order and condition all electrical, plumbing, sanitary, heating, ventilating, and air conditioning fixtures and appliances, and elevators, supplied or required to be supplied by the landlord;(5) When the landlord is a party to any rental agreements that cover four or more dwelling units in the same structure, provide and maintain appropriate receptacles for the removal of ashes, garbage, rubbish, and other waste incidental to the occupancy of a dwelling unit, and arrange for their removal;(6) Supply running water, reasonable amounts of hot water, and reasonable heat at all times, except where the building that includes the dwelling unit is not required by law to be equipped for that purpose, or the dwelling unit is so constructed that heat or hot water is generated by an installation within the exclusive control of the tenant and supplied by a direct public utility connection;(7) Not abuse the right of access conferred by division (B) of section 5321.05 of the Revised Code;(8) Except in the case of emergency or if it is impracticable to do so, give the tenant reasonable notice of the landlord's intent to enter and enter only at reasonable times.

Maybe you can arrange some type of referral arrangement.

If something needs to be done you can have them arrange the time for it with the vendor. 

How utilities are billed to Tenants depends on several factors including previous lease arrangement and how utilities are metered in a building.

You could show the arrangement with the paperwork.

However, I have no idea how you address the self-management tax issue in this arrangement if its all owned by you.So, of course, consult with some qualified professionals for the structure that works for you.But, if you were asking about a portfolio loan, I think there has been a fair amount of responses here, but nothing directly if the properties need to be held in one LLC.  

But my question is, IF someone is actually occupying the mobile home, can I change the locks and the electricity over to my name, essentially locking out that person who will be technically "squatting" since the actual owner died awhile ago and I as the new owner don't have any contract/ lease/ rental agreement arrangements with?
