After September 30, 1997, financial assistance for rental housing assistance under the United States Housing Act of 1937 [42 U.S.C. 1437 et seq.] may not be provided to any Indian housing authority or tribally designated housing entity, unless such assistance is provided pursuant to a contract for such assistance entered into by the Secretary and the Indian housing authority before such date. Any such assistance provided pursuant to such a contract shall be governed by the provisions of the United States Housing Act of 1937 (as in effect before the date of the effectiveness of this chapter) and the provisions of such contract.

Nothing in this chapter or an amendment made by this chapter prohibits or prevents any participating jurisdiction (within the meaning of the HOME Investment Partnerships Act (42 U.S.C. 12721 et seq.)) from providing any amounts made available to the participating jurisdiction under that Act (42 U.S.C. 12721 et seq.) to an Indian tribe or a tribally designated housing entity for use in accordance with that Act (42 U.S.C. 12721 et seq.).
