The Secretary is authorized to make such rules and regulations, to enter into such agreements, and to adopt such procedures as he may deem necessary or desirable to carry out the provisions of this section. Nothing contained in this section shall affect the authority of the Secretary of Housing and Urban Development with respect to any housing assisted under this section, section 221(d)(3), section 231(c)(3), or section 236 of the National Housing Act [ 12 U.S.C. 1715 l (d)(3), 1715v(c)(3), 1715z–1], or section 1701q of this title , including the authority to prescribe occupancy requirements under other provisions of law or to determine the portion of such housing which may be occupied by qualified tenants. To ensure that qualified tenants occupying that number of units with respect to which assistance was being provided under this section immediately prior to November 30, 1983 , receive the benefit of assistance contracted for under this section, the Secretary shall offer annually to amend contracts entered into with owners of projects assisted under this section but not subject to mortgages insured under title II of the National Housing Act [ 12 U.S.C. 1707 et seq.] to provide sufficient payments to cover 100 percent of the necessary rent increases and changes in the incomes of qualified tenants, subject to the availability of authority for such purpose under section 1437c(c) of title 42 . The Secretary shall take such actions as may be necessary to ensure that payments, including payments that reflect necessary rent increases and changes in the incomes of tenants, are made on a timely basis for all units covered by contracts entered into under this section.
