The lien of assessments to pay refunding bonds and the interest thereon shall be on a parity with the lien of general taxes, and no sale of property for the nonpayment of general taxes shall extinguish the lien of such assessments. Except as provided by this article, the lien of any assessment levied against appraised benefits or otherwise for the payment of an original issue of bonds and interest thereon shall continue and persist for the benefit of the owners of refunding bonds, which owners shall be subrogated to all the rights and remedies of the owners of bonds refunded; except that if there is a reduction in the amount of outstanding bonds there shall be a corresponding reduction in the amount of the lien.
