Any person may, at any interest-payment period after the fifth installment of his assessment has become due and has been paid, pay the entire balance of such assessment against his property with accrued interest to the next succeeding interest period. In the event that an owner who has entered into an installment payment agreement desires to pay his assessment in full before the fifth installment thereof has become due, he may pay the same by paying the face amount of his obligation, plus all installments of interest up to and including the next interest period following the fifth installment.
