Can a trailor park (mobile Home park) evict a tenet when all the monthly rent payments were paid on time, or chose not to renew a lease agreement.

I think there are two questions here.  One is whether a landlord can refuse to renew a lease even when all payments were made under the lease.  Yes.  The other question is whether the landlord is going through the proper procedures in the effort to evict.  Each state will have its own unique laws setting out the necessary notices, etc that must precede an eviction suit.  If there is a genuine belief that those procedures are not being followed, your daughter should consult a good real estate lawyer in her area.  As an aside, there are practical implications that need to be considered here.  Even if the landlord has failed to follow precisely the rules that govern eviction procedures, it will probably be costly to fight the process in court.  Is it worth the cost of litigation (time, money and energy) to try and retain the place knowing the landlord and at least some of the neighbors are not happy with her being there?  Even if she succeeds in stopping the present effort, the landlord, if he/she elects, can still refuse to renew the lease at the end of the lease term.
