3. This section does not limit the discretion of the governing body in determining whether assessments are payable in installments and the time the first installment of principal or interest, or both, and any subsequent installments thereof, are due.

4. The governing body in the assessment ordinance shall state the number of installments in which assessments may be paid, the period of payment, any privileges of making prepayments and any premium to be paid to the municipality for exercising any such privilege, the rate of interest upon the unpaid balance of the assessment and accrued interest after any delinquency at a rate not exceeding 2 percent per month, and any penalties and collection costs payable after delinquency.

The governing body shall apply the credit pro rata, based on the original assessment on the assessed property, against the payment of the assessment due from the person who owns the assessed property on the date of the application of the credit.
