Within 45 days after receiving the return of unpaid taxes from the collecting officer, or as soon thereafter as is practicable, the enforcing officer shall notify, by first class mail, all potential eligible owners of their possible eligibility to make installment payments on such tax delinquencies. The enforcing officer shall add $1 to the amount of the tax lien for such mailing.
The failure to mail any such notice, or the failure of the addressee to receive the same, shall not in any way affect the validity of taxes or interest prescribed by law with respect thereto.
The enforcing officer shall not be required to notify the eligible owner when an installment is due or overdue.
