If you received an invoice from the county tax assessor for property taxes that you do not believe that you owe for the house that you own at the trailer park that you live at you need to immediately contact the county tax assesor where you live and set up an appointment to meet with a representative of it to go over the recent invoice.You need to bring with you all paperwork that you have supporting your position that the new assessment is incorrect as well as all payments that you have made in the past. If you do not own the land where your mobile home is located, most likely you do not owe the taxes assessed. Rather, most likely the owner of the trailer park owes on the tax bill that you recently received and he or she is trying to pass on his or her assessment on to you.Good luck.
