On request by the Secretary of Defense, the Attorney General shall furnish to the Secretary of Defense, or his designee, an opinion as to the sufficiency of title to any property on which it is proposed to construct housing, or on which housing has been constructed, under this section. If the opinion of the Attorney General is that the title to any such property is good and sufficient, the Secretary of Defense is authorized to guarantee, or enter into a commitment to guarantee, the mortgagee, under a mortgage on such property which is insured under title VIII of the National Housing Act [12
et seq.], against any losses that may thereafter arise from adverse claims to title. None of the proceeds of any mortgage loan hereafter insured under such title VIII shall be used for title search and title insurance costs: Provided, That if the Secretary of Defense, or his designee, determines in the case of any housing project, that the financing of the construction of such project is impossible unless title insurance is provided, the Secretary of Defense may provide for the payment of the reasonable costs necessary for obtaining title search and title insurance. Any payments by the Secretary of Defense hereunder shall be made from the revolving fund established under section
of this title. Any determination by the Secretary of Defense under the foregoing proviso shall be set forth in writing, together with the reasons therefor. The Committees on Armed Services of the Senate and House of Representatives shall be promptly notified of each such determination, and of the amount of any payment made by the Secretary of Defense for title search and title insurance costs.
