I usually sell IUL so if I'm missing something let me know. This is about PUA in regards to infinite banking. If the policy had been designed optimally from the start, there should not be room for 1-cent more of paid up additions. The interest on the policy loan is paid back to the insurance company. This optimally-designed gives for example a real estate investor a higher "credit line" from which to borrow against right from the beginning. What am I missing?
