(1) The reasonable exercise by any person engaged in any such business of his right to approve or disapprove the insurance or the insurer selected to write the insurance, on reasonable grounds related to the risk selection or underwriting practices of the insurer, the adequacy and terms of the coverage with respect to the interest of such person to be insured thereunder, the quality of service rendered by the insurer or its representative in connection with the insurance, and the financial standards to be met by the insurer; nor of his right to furnish such insurance or to renew any insurance required by the contract of sale or mortgage, trust deed or other loan agreement if the borrower or purchaser has failed to furnish the insurance or renewal thereof within such reasonable time or form as may be specified in the sale or loan agreement. The lender or vendor shall not refuse to accept insurance provided by an acceptable insurer on the ground that such insurance provides more coverage than is required in the sale or loan agreement, unless the additional coverage consists of life or disability insurance.
(2) The free choice of insurance agent or broker by any borrower or purchaser at any time, and he may revoke any designation of insurance agent or broker at any time irrespective of the provisions of any loan or purchase agreement, mortgage, or trust deed.
(3) The exercise by any person engaged in such business of his right to furnish such insurance or to renew such insurance, and to charge the account of the borrower or purchaser with the costs thereof, if the borrower or purchaser fails to deliver to the lender or vendor such insurance at least thirty (30) days prior to expiration of the existing policy. If an insurance policy procured by the borrower or purchaser is subsequently substituted for that then in force, the lender or vendor may impose a reasonable service charge as determined by the director for the transaction, and payment of such charge by the agent or broker shall not be a violation of any other provision of this code. No service charge shall be imposed for normal insurance changes made during the term of the policy.
(4) The director may adopt a uniform statewide schedule of permissive maximum charges for the substitution of policies authorized in subdivision (3) above.
