Upon completion of redemption, the county treasurer to whom redemption has been made shall enter the word "redeemed", the date of redemption and by whom redeemed on the certificate and on the margin of the assessment book where the entry of the certificate is made. If the property is not redeemed within two years, after the fifteenth day of January of the year in which such property was sold, the county treasurer of the county in which the land sold is situated must thereafter, upon demand of the owner of the certificate of sale, make to the purchaser, or his or her assignees a deed of the property, reciting in the deed substantially the matters contained in the certificate, and that no person redeemed the property during the time allowed by law for its redemption. The treasurer shall receive from the purchaser, for the use of the district, one dollar for making such deed: PROVIDED, If redemption is not made of any lot, parcel, or tract of land not larger than one acre, the fee for a deed shall be twenty-five cents and when any person or district holds a duplicate certificate covering more than one tract of land, the several parcels, or tracts of lands, mentioned in the certificate may be included in one deed.
