If the combined taxes and assessment installments under Plan One or delinquent Plan Two are not paid, the parcel may be sold for all such taxes and assessments in accordance with chapter 10-23. There may be no separate sale as provided in § 10-23-1 but each parcel may be sold for both taxes and special assessments at a single sale, and redemption must be made by payment of all such special assessments and taxes. No tax sale relieves the land from liability for subsequent installments of special assessments.
