In addition to the other programs authorized by this chapter, the Alaska Housing Finance Corporation may make loans in order to encourage and facilitate the construction or rehabilitation of housing to meet the needs of displaced persons. These loans are a part of the federally assisted project cost and may be made to nonprofit, limited dividend, or cooperative organizations, or to public bodies. The loans may be made only for necessary and reasonable expenses, before construction, for planning and obtaining federally insured mortgage financing for the rehabilitation or construction of housing for displaced persons. The loans may not exceed 80 percent of the reasonable costs expected to be incurred in planning, and in obtaining financing for housing for displaced persons. Reasonable costs include but are not limited to costs for preliminary surveys and analysis of market needs, preliminary architectural fees, site acquisition, application and mortgage commitment fees, and construction loan fees and discounts. Loans to an organization established for profit shall bear interest at a market rate established by the Alaska Housing Finance Corporation. All other loans shall be without interest. The Alaska Housing Finance Corporation shall require repayment of loans made under this section under terms and conditions that it may prescribe. Repayment shall be made upon completion of the project or sooner, and except in the case of a loan to an organization established for profit, the Alaska Housing Finance Corporation may cancel any part or all of a loan if the corporation determines that a permanent loan to finance the rehabilitation or construction of the housing cannot be obtained in an amount adequate for repayment of the loan.
