An escrow fee of a reasonable amount may be charged for any loan made which is secured primarily by real property when such services are actually performed. Such fee shall be considered reasonable when paid to a company licensed to do business under the Escrow Law, Division 6 (commencing with Section 17000), or any person exempted by the Escrow Law, provided that such fees are comparable to fees being charged by escrow companies so authorized to do business in this state. Such fee is not included in computing the maximum charges which may be made under this division.
