The powers conferred by this Act are in addition and supplemental to, and the limitations imposed by this Act shall not affect, the powers conferred upon Authorities by any other law. This Act is not a limitation upon the powers of home rule units. Home mortgage loans may be acquired, purchased, and financed, and bonds may be issued under this Act for those purposes, notwithstanding that any other law or power may provide for the acquisition, purchase, and financing of like home mortgage loans, or the issuance of bonds for like purposes, and without regard to the requirements, restrictions, limitations, or other provisions contained in any law, including any law relating to any requirement of competitive bidding or restriction imposed on the sale or disposition of property or award of contracts. Nothing in this Act shall be deemed or construed to prohibit the exercise of the powers conferred upon Authorities in connection with the financing of federally assisted housing for persons of low and moderate income.
