With respect to a multifamily project, hospital, or group practice facility covered by a mortgage insured under any section or subchapter of this chapter or covered by a mortgage held by the Secretary, the Secretary is authorized, upon such terms and conditions as he may prescribe, to make commitments to insure, and to insure, supplemental loans (including advances during construction or improvement) made by financial institutions approved by the Secretary. As used in this section, “supplemental loan” means a loan, advance of credit, or purchase of an obligation representing a loan or advance of credit made for the purpose of financing improvements or additions to such project, hospital, or facility: Provided, That a loan involving a nursing home, hospital, or a group practice facility may also be made for the purpose of financing equipment to be used in the operation of such nursing home, hospital, or facility.
The provisions of subsections (d), (e), (g), (h), (i), (j), (k), (l), and (n) of section 1713 of this title shall be applicable to loans insured under this section, except that (1) all references to the term “mortgage” shall be construed to refer to the term “loan” as used in this section, (2) loans involving projects covered by a mortgage insured under section 1715e of this title that is the obligation of the Cooperative Management Housing Insurance Fund shall be insured under and shall be the obligation of such fund, and (3) loans involving projects covered by a mortgage insured under section 1715z–1 of this title shall be insured under and shall be the obligation of the Special Risk Insurance Fund.
Notwithstanding the foregoing, the Secretary may insure a loan for improvements or additions to a multifamily housing project, or a group practice or medical practice facility or hospital or other health facility approved by the Secretary, which is not covered by a mortgage insured under this chapter, if he finds that such a loan would assist in preserving, expanding, or improving housing opportunities, or in providing protection against fire or other hazards. Such loans shall have a maturity satisfactory to the Secretary and shall meet such other conditions as the Secretary may prescribe. In no event shall such a loan be insured if it is for an amount in excess of the maximum amount which could be approved if the outstanding indebtedness, if any, covering the property were a mortgage insured under this chapter. At any sale under foreclosure of a mortgage on a project or facility which is not insured under this chapter but which is senior to a loan assigned to the Secretary pursuant to subsection (c), the Secretary is authorized to bid, in addition to amounts authorized under section 1713(k) of this title, any sum up to but not in excess of the total unpaid indebtedness secured by such senior mortgage, plus taxes, insurance, foreclosure costs, fees, and other expenses. In the event that, pursuant to subsection (c), the Secretary acquires title to, or is assigned, a loan covering a project or facility which is subject to a mortgage which is not insured under this chapter, the Secretary is authorized to make payments from the General Insurance Fund on the debt secured by such mortgage, and to take such other steps as the Secretary may deem appropriate to preserve or protect the Secretary’s interest in the project or facility.
