Most of these mobile home parks have "lifetime lease agreements" which automatically renew on either the anniversary date of the execution of the agreement or on January 1st. The standard agreement usually contains a provision the agreement can be canceled by 90 days written notice to the owner. Check your lease agreement for cancellation language.
You don't mention how the park owner is making it difficult to rent the unit. Florida Statutes Chapter 723 governs lot tenancies for mobile homes and contains some duties and restrictions that might be applicable, but without any information I cannot give you a complete answer.
