§ 89. Lien for taxes, etc.

There shall be a lien on all real estate and on each and every interest therein for the city taxes assessed thereon, from the commencement of the year for which they were assessed and also for all local assessments which may be made thereon according to law. There shall also be a lien on any land or premises for the amount of expense incurred by said city in abating any nuisance thereon or cutting or removing weeds therefrom, after notice to the owner thereof by publication or otherwise as may be provided by ordinance; provided, however, that the lien for the amount of any such local assessment or for the expense of abating any nuisance or cutting or removing weeds from any premises shall not be good against a purchaser of such land or premises for value without notice except and until from the time that the same shall be docketed in a book or books kept for that purpose in the office of the city treasurer and indexed in the name of the person or persons owning such estate or land at the time the said lien accrued. The council may require such real estate in the city delinquent for the nonpayment of taxes, or assessments or expenses incurred as above provided, to be sold for said taxes or assessments or expenses, with interest thereon at the rate of six per centum per annum, and such percentage as may be prescribed for charges.
