If the property described in any delinquency certificate is not redeemed within two (2) years from the date thereof, the treasurer, after having given notice as hereinafter required, shall issue a deed thereto to the district, or if the same has been assigned as hereinbefore provided, then to the person holding the original delinquency certificate under assignment, upon request therefor, and upon the delivery to the treasurer of such original certificate and filing proof of having given notice as required by the treasurer before making a deed to the district. Such deed shall recite substantially the matter contained in the certificate and that no person redeemed the property within the time allowed, by law, for its redemption. It shall be signed and acknowledged by the treasurer in the manner required, by law, to entitle the same to be recorded under the laws of this state; provided, that such deed shall not be issued to an assignee until he has paid all subsequent installments and assessments of the local improvement district then delinquent or due upon the property described in the delinquency certificate, together with the penalties and interest thereon. Such deed to an assignee shall be made subject to all unpaid installments not then due and subject to all regular or special assessments of the district, not related to the local improvement district.
