If the buyer of the mobile home has failed to remove it from your property within the time period that you wanted, I would write him or her a letter setting forth a monthly rental of so much per day for each day it remains. If the rent is not paid, you should then consult with a landlord tenant attorney about filing a lawsuit for removal of the mobile home (mandatory injunction) and damages for the daily rent stated in your letter.Keep a copy of the letter for future use and need.
