The landloord for the mobile home park where the unit is located can refuse to enter into a term lease with you where you are paying on a month-to-month lease. The landlord is under no legal or contractual obligation to change the terms of the status quo of the rental situation.Likewise, the landlord can refuse to rent to anyone who is not an owner of the unit you are writing about. However, most likely, you can enter into a sublease between you and another person to rent a room in the unit you presently occupy. To be sure, I suggest that you consult with a landlord tenant attorney.
