Creating a LLC, renting to myself

[John Nail]

If I buy a duplex and live in one side, can I create an LLC to control and protect both sides?

Basically I want both rent payments to go to the LLC to pay off the mortgage faster. I figure if I have to rent an apartment now anyway might as well pay the same amount and rent it to myself. Or does that cause a confusion with the bank when I claim I am the owner/occupant?
