Duplex with two owners how to split deductions

I own a duplex with another individual.  That individual lives in one half, and the other side is rented out.  When it comes to Schedule E, I know I take half of the rented sides depreciation and also include half of the income, but do I get to take half of the property tax, mortgage interest, and insurance as deductions on Schedule E, for the other person would take half since they live there on their 1040.
