When an assessment is payable in installments, default in the payment of any installment of principal or interest when due shall cause the whole of the unpaid principal and interest to become due and payable immediately, and the whole amount of the unpaid principal shall thereafter draw interest at the rate of ten percent (10%) per annum until paid; but, at any time prior to the date of sale in proceedings to enforce the lien of the delinquent assessments, the owner may pay the amount of all unpaid installments past due, with interest at the rate of ten percent (10%) per annum to date of payment on the delinquent installments, and all proper costs, and shall thereupon be restored to the right thereafter to pay in installments in the same manner as if default had not occurred.
