You don't rent out a portion of your home and not not an owner-occupied rental. You are renting out a separate dwelling unit/apartment. Treat it as a completely separate rental.
For any costs that are shared by both your home and the rental, enter 17% (or whatever is appropriate) of those expenses for the rental. Then for your personal itemized deductions, you'll enter that 83% on Schedule A. Does that make sense?
