Cal. Health & Saf. Code § 33762
An agency may establish limitations respecting fees, charges, and interest rates to be used by qualified mortgage lenders for financing residential construction pursuant to this chapter and may from time to time revise such fees, charges, and interest rates to reflect changes in interest rates on the agency's revenue bonds, losses due to defaults, changes in loan-servicing charges, or other expenses related to administration of the residential construction financing program. Any change in interest rate shall conform to the provisions of Section 1916.5 of the Civil Code, except that paragraph (3) of subdivision (a) of Section 1916.5 shall not apply and that the "prescribed standard" specified in Section 1916.5 shall be periodically determined by the redevelopment agency after hearing preceded by public notice to affected parties, and shall reflect changes in interest rates on the agency's bonds, and bona fide changes in loan servicing charges related to the administration of a program under the provisions of this chapter. An agency may purchase mortgage or construction loans made by a qualified mortgage lender without premium or may itself pay such fees and charges incurred in lending money for the purpose of residential construction and may collect and disburse, or may contract to pay any person, partnership, association, corporation, or public agency for, collection and disbursal of payments of principal, interest, taxes, insurance, and mortgage insurance. An agency may hold deeds of trust or mortgages, including mortgages insured under Title II of the National Housing Act, as security for financing residential construction and may pledge or assign the same as security for repayment of revenue bonds. Such deeds of trust or mortgages may be assigned to, and held on behalf of the agency by, any bank or trust company appointed to act as trustee or fiscal agent by the agency in any indenture or resolution providing for issuance of bonds pursuant to this chapter. An agency may establish the terms and conditions of financing, which shall be consistent with the provisions of any applicable federal or state law under which the financing is to be insured.
