The owner of property sold for delinquent assessments, or any other party interested in said property, shall have the right to redeem, upon the payment of the principal amount of the installment or installments then delinquent, and the penalties on such delinquent installment or installments as provided for delinquent taxes. Failure to redeem within two years shall vest the title in the purchaser at said sale, subject to the lien of any and all unmatured installments. Such redemption shall not discharge said property from the lien of unmatured assessments levied thereon, and said property shall remain subject to such lien as if no sale thereof had been made.
