Where an insurance company, as a condition for a loan by such company, of money upon mortgage or other security, requires that the borrower insure either his life or that of another, or his property, or the title to his property, with the company, and assign or cause to be assigned to it a policy of insurance as security for the loan, and agree to pay premiums thereon during the continuance of the loan, whether the premium is paid annually, semiannually, quarterly, or monthly, such premiums shall not be considered as interest on such loans, nor will any loan be rendered usurious by reason of any such requirements, where the rate of interest charged for the loan does not exceed the legal rate and where the premiums charged for the insurance do not exceed the premiums charged to other persons for similar policies who do not obtain loans.
