Cal. CIV § 1917.069

The aggregate amount of any fee charged to the borrower for processing an application and preparing any necessary documents in connection with originating a shared appreciation loan shall not exceed the reasonable cost of providing the service. No prepaid interest shall be charged to the borrower, but nothing in this chapter shall preclude a lender from requiring a fee for providing commitments for shared appreciation loans to builders or others who will not be the ultimate borrower.
