If your family and you own a trailer park and wish to close it up where all tenants are on a month-to-month tenancy, you need to have a thirty (30) day notice of termination of the lease prepared and served personally upon all tenants by a third person stating the reasons why the mobile home park is being shut down the and the reasons why their tenancy is being terminated.This will put all tenants on notice about the need for them to start looking for another place to live. I recommend that you retain an attorney experienced in commercial landlord tenant relations to assist you concerning the subject that you are writing about and to hopefully make the closing process easier for you and your family.
