The Secretary, subject to such special conditions as the Secretary may prescribe, may insure under any provision of this subchapter that authorizes such insurance, a mortgage covering a property upon which there is located a one- to four-family residence, without regard to any limitation in this chapter relating to marketability of title or any other limitation in this chapter that the Secretary determines is contrary to promoting the availability of such insurance on Indian reservations if the mortgage (1) is executed by an Indian tribe and the property is located on trust or otherwise restricted land; or (2) is executed by a member of an Indian tribe who will use the property as a principal residence and the property is on trust or otherwise restricted land.
A mortgage insured under this section may be assumed, subject to credit approval by the lender and the consent of the tribe to an assumption of the existing lease or the grant of a new lease, without an adjustment of the interest rate. Any other sale of a property subject to a mortgage insured under this section may be made only if a new lease is granted, except that a sale following a foreclosure may be accompanied by an assumption of the lease with the consent of the tribe.
Notwithstanding any other provision of this chapter, the insurance of a mortgage using the authority contained in this section shall be the obligation of the Mutual Mortgage Insurance Fund. The mortgagee shall be eligible to receive the benefits of insurance as provided in section 1710 of this title with respect to mortgages insured pursuant to this section, except that all references in section 1710 of this title to section 1709 of this title shall be construed to refer to the section under which the mortgage is insured.
In the administration of this section, the Secretary shall establish a premium charge for insurance that will be sufficient to cover the full costs of the mortgage insurance program under this section, except that such charge may not exceed 3 percent per annum of the principal amount of the mortgage outstanding at any time. Not later than September 30, 1984, the Secretary shall determine and report to the Congress on the feasibility of eliminating any excess amount of the premium under this section over the premium under section 1709 of this title. In the event such premiums are not sufficient to cover the full costs of the mortgage insurance program under this section, the Secretary shall make recommendations to the Congress about changes to the program.
