How many years does it take to make up the 9-year property fee arrears?

Nine years. In the property service contract, the owner and the property company agreed on the payment method and time limit of the property fee. If the owner fails to pay the property fee on time, the property company has the right to ask the owner to pay the arrears. In this case, the owner needs to pay the overdue fee according to the time limit agreed in the contract.
