12 U.S.C. § 1738

(a) Relief of housing shortage; eligibility; limitations on time and amount In order to assist in relieving the acute shortage of housing which now exists and to increase the supply of housing accommodations available to veterans of World War II at prices within their reasonable ability to pay, the Secretary is authorized, upon application by the mortgagee, to insure as hereinafter provided any mortgage which is eligible for insurance as hereinafter provided, and, upon such terms as the Secretary may prescribe, to make commitments for the insuring of such mortgages prior to the date of their execution or disbursement thereon: Provided , That the aggregate amount of principal obligations of all mortgages insured under this subchapter shall not exceed $6,150,000,000 except that with the approval of the President such aggregate amount may be increased to not to exceed $6,650,000,000: Provided further , That no mortgage shall be insured under this section after April 30, 1948 , except (A) pursuant to a commitment to insure issued on or before April 30, 1948 , or (B) a mortgage given to refinance an existing mortgage insured under this section and which does not exceed the original principal amount and unexpired term of such existing mortgage, and no mortgage shall be insured under section 1743 of this title after March 1, 1950 , except (i) pursuant to a commitment to insure issued on or before March 1, 1950 , or (ii) a mortgage given to refinance an existing mortgage insured under section 1743 of this title and which does not exceed the original principal amount and unexpired term of such existing mortgage: Provided further , That no mortgage shall be insured under section 1743 of this title unless the mortgagor certifies under oath that in selecting tenants for the property covered by the mortgage he will not discriminate against any family by reason of the fact that there are children in the family, and that he will not sell the property while the insurance is in effect unless the purchaser so certifies, such certifications to be filed with the Secretary; and violation of any such certification shall be a misdemeanor punishable by a fine of not to exceed $500: And provided further , That the Secretary shall, in his discretion, have power to require the availability for rental purposes of properties covered by mortgages insured under this subchapter, in such instances and for such periods of time as he may prescribe. Notwithstanding the first proviso of this subsection, mortgages may be insured under sections 1744 and 1746 of this title if the aggregate amounts of principal obligations of mortgages insured under said sections plus the aggregate amount of principal obligations of mortgages insured under section 1745 of this title do not exceed the limitation contained in said section 1745 upon the aggregate amount of principal obligations of mortgages insured pursuant to said section. Notwithstanding the second proviso of this subsection, mortgages otherwise eligible for insurance under section 1743 of this title may be hereafter insured thereunder if the application for such insurance was received by the Department of Housing and Urban Development on or before March 1, 1950 , and for such purpose the aggregate amount of principal obligations authorized to be insured under section 1743 of this title is increased by not to exceed $500,000,000. (b) Eligibility requirements To be eligible for insurance under this section a mortgage shall— (1) have been made to, and be held by, a mortgagee approved by the Secretary as responsible and able to service the mortgage properly; (2) involve a principal obligation (including such initial service charges, appraisal, inspection, and other fees as the Secretary shall approve) in an amount not to exceed 90 per centum of the Secretary’s estimate of the value (as of the date the mortgage is accepted for insurance), except that as to applications received by the Secretary on or before March 31, 1948 , the mortgage may involve a principal obligation in an amount not to exceed 90 per centum of the Secretary’s estimate of the necessary current cost (including the land and such initial service charges and such appraisal, inspection, and other fees as the Secretary shall approve); of a property, urban, suburban, or rural, upon which there is located a dwelling designed principally for residential use for not more than four families in the aggregate, which is approved for mortgage insurance prior to the beginning of construction. The principal obligation of such mortgage shall in no event, however, exceed— (A) $5,400 if such dwelling is designed for a single-family residence, or (B) $7,500 if such dwelling is designed for a two-family residence, or (C) $9,500 if such dwelling is designed for a three-family residence, or (D) $12,000 if such dwelling is designed for a four-family residence: Provided , That the Secretary may, if he finds that at any time or in any particular geographical area it is not feasible, within such limitations of maximum mortgage amounts, to construct dwellings without sacrifice of sound standards of construction, design, or livability, prescribe by regulation or otherwise higher maximum mortgage amounts not to exceed— (A) $8,100 if such dwelling is designed for a single-family residence, or (B) $12,500 if such dwelling is designed for a two-family residence, or (C) $15,750 if such dwelling is designed for a three-family residence, or (D) $18,000 if such dwelling is designed for a four-family residence. (3) have a maturity satisfactory to the Secretary but not to exceed twenty-five years from the date of the insurance of the mortgage; (4) contain complete amortization provisions satisfactory to the Secretary; (5) bear interest (exclusive of premium charges for insurance) at not to exceed 4 per centum per annum on the amount of the principal obligation outstanding at any time; (6) provide, in a manner satisfactory to the Secretary, for the application of the mortgagor’s periodic payments (exclusive of the amount allocated to interest and to the premium charge which is required for mortgage insurance as herein provided) to amortization of the principal of the mortgage; and (7) contain such terms and provisions with respect to insurance, repairs, alterations, payment of taxes, default reserves, delinquency charges, foreclosure proceedings, anticipation of maturity, additional and secondary liens, and other matters as the Secretary may in his discretion prescribe. (c) Premium charges; payments; acceptance for insurance; preferences; adjustments and refunds The Secretary is authorized to fix a premium charge for the insurance of mortgages under this subchapter but in the case of any mortgage such charge shall not be less than an amount equivalent to one-half of 1 per centum per annum nor more than an amount equivalent to 1½ per centum per annum of the amount of the principal obligation of the mortgage outstanding at any time, without taking into account delinquent payments or prepayments. Such premium charges shall be payable by the mortgagee, either in cash, or in debentures issued by the Secretary under this subchapter at par plus accrued interest, in such manner as may be prescribed by the Secretary: Provided , That the Secretary may require the payment of one or more such premium charges at the time the mortgage is insured, at such discount rate as he may prescribe not in excess of the interest rate specified in the mortgage. If the Secretary finds, upon the presentation of a mortgage for insurance and the tender of the initial premium charge and such other charges as the Secretary may require, that the mortgage complies with the provisions of this subchapter, such mortgage may be accepted for insurance by endorsement or otherwise as the Secretary may prescribe; but no mortgage shall be accepted for insurance under this subchapter unless the Secretary finds that the project with respect to which the mortgage is executed is an acceptable risk in view of the shortage of housing referred to in this section. In the event that the principal obligation of any mortgage accepted for insurance under this subchapter is paid in full prior to the maturity date, the Secretary is further authorized in his discretion to require the payment by the mortgagee of an adjusted premium charge in such amount as the Secretary determines to be equitable, but not in excess of the aggregate amount of the premium charges that the mortgagee would otherwise have been required to pay if the mortgage had continued to be insured under this subchapter until such maturity date; and in the event that the principal obligation is paid in full as herein set forth, the Secretary is authorized to refund to the mortgagee for the account of the mortgagor all, or such portion as he shall determine to be equitable, of the current unearned premium charges theretofore paid. The Secretary shall prescribe such procedures as in his judgment are necessary to secure to veterans of World War II, and their immediate families, and to hardship cases as defined by the Secretary, preference or priority of opportunity to purchase or rent properties covered by mortgages insured under this subchapter. (d) Conclusiveness of insurance contract as to eligibility Any contract of insurance heretofore or hereafter executed by the Secretary under this subchapter shall be conclusive evidence of the eligibility of the mortgage for insurance, and the validity of any contract of insurance so executed shall be incontestable in the hands of an approved mortgagee from the date of the execution of such contract, except for fraud or misrepresentation on the part of such approved mortgagee.
