In addition to the right of the City to foreclose its lien for taxes as provided for in its Charter and the general laws, the right of the City to receive taxes, assessments and water rents and the lien thereof, may be sold by the City, and after such sale, shall be transferred in the manner provided by this article. In this article, unless the context otherwise requires, the word "tax" shall be interpreted as including water rents, expenses incurred in repairing, grading and removing snow and ice from sidewalks, assessments and all other items inserted in the annual tax rolls and made a part of the annual tax upon lands and tenements thereon. The right and lien so sold shall be called "tax lien" and the instrument by which it is assigned shall be called "transfer of tax lien."
