In addition to the powers conferred upon a municipality by other provisions of this act, a municipality is empowered to borrow money or accept contributions, grants or other financial assistance from the federal government for or in aid of any housing project within its area of operation, to take over, lease or manage any project or undertaking constructed or owned by the federal government, and to these ends, to comply with such conditions and enter into such contracts, covenants, mortgages, trust indentures, leases or agreements as may be necessary, convenient or desirable. It is the purpose and intent of this act to authorize every municipality to do any and all things necessary or desirable to secure the financial aid or cooperation of the federal government in the undertaking, construction, maintenance or operation of any housing project by such municipality. To accomplish this purpose a municipality, notwithstanding the provisions of any other law, may include in any contract for financial assistance with the federal government any provisions, which the federal government may require as conditions to its financial aid of a housing project, not inconsistent with the purposes of this act.
