The city may fix fees, charges, and interest rates for construction loans, mortgage loans, loans to lenders and participation purchases and may from time to time revise such fees, charges, and interest rates to reflect changes in interest rates on the city’s bonds, losses due to defaults, changes in loan servicing charges, or changes in other expenses related to such loans, including city administrative expenses. Any change in interest rate shall conform to the provisions of Section 1916.5 of the California Civil Code, and shall reflect changes in interest rates on the city’s bonds, losses due to defaults, changes in loan servicing charges, and changes in such other expenses related to the program. (Ord. 1505 NCS §1 (part), 1982.)
