The amount of any financial assistance provided under this section for low-rent housing and related facilities shall not exceed 90 per centum of the total development cost thereof, as determined by the Secretary, less such amount as the Secretary determines can be practicably obtained from other sources (including a loan under section 1484 of this title).
The Secretary may make payments pursuant to any contract for financial assistance under this section at such times and in such manner, as may be specified in the contract. In each contract, the Secretary shall include such covenants, conditions, or provisions as he deems necessary to insure that the housing and related facilities, for which financial assistance is made available, be used only in conformity with the provisions of this section.
All laborers and mechanics employed by contractors or subcontractors on projects assisted by the Secretary which are undertaken by approved applicants under this section shall be paid wages at rates not less than those prevailing on similar construction in the locality, as determined by the Secretary of Labor in accordance with sections 3141–3144, 3146, and 3147 of title 40. The Secretary shall not extend any financial assistance under this section for any project without first obtaining adequate assurance that these labor standards will be maintained on the construction work; except that compliance with such standards may be waived by the Secretary in cases or classes of cases where laborers or mechanics, not otherwise employed at any time on the project, voluntarily donate their services without compensation for the purpose of lowering the costs of construction and the Secretary determines that any amounts thereby saved are fully credited to the person, corporation, association, organization, or other entity, undertaking the project. The Secretary of Labor shall have, with respect to the labor standards specified in this section, the authority and functions set forth in Reorganization Plan Numbered 14 of 1950 (15 F.R. 3176; 64 Stat. 1267), and section 3145 of title 40.
Notwithstanding the provisions of subsection (a)(3), the Secretary may, upon a finding of persistent need for migrant farmworker housing in any area, provide assistance to eligible applicants for 90 per centum of the development costs of such housing in such area to be used solely by migrant farmworkers while they are away from their residence. Such housing shall be constructed in such a manner as to be safe and weatherproof for the time it is to be occupied, be equipped with potable water and modern sanitation facilities (including a kitchen sink, toilet, and bathing facilities), and meet such other requirements as the Secretary may prescribe.
The Secretary shall utilize not more than 10 per centum of the amounts available for any fiscal year for purposes of this section for financial assistance to eligible private and public nonprofit agencies to encourage the development of domestic and migrant farm labor housing projects under this subchapter.
Any advance provided under subparagraph (A)(i) shall be repaid on such terms as may be prescribed by the Secretary when the project ceases to be used as housing in accordance with the provisions of this subsection. Recipients shall be required to repay 100 percent of the advance if the housing is used for purposes under this subsection for fewer than 10 years following initial occupancy. If the housing is used for such purposes for more than 10 years, the percentage of the amount that shall be required to be repaid shall be reduced by 10 percentage points for each year in excess of 10 that the property is so used.
Upon any sale or other disposition of housing acquired or rehabilitated with assistance under this subsection prior to the close of 20 years after the housing is placed in service, other than a sale or other disposition resulting in the use of the project for the direct benefit of low income persons or where all of the proceeds are used to provide housing for migrant farmworkers and homeless individuals (and the families of such individuals), the recipient shall comply with such terms and conditions as the Secretary may prescribe to prevent the recipient from unduly benefiting from the sale or other disposition of the project.
