I own a duplex, and I live in one half and rent out the other. I have questions about how to approach the mortgage interest and property taxes.

The taxes and interest are included on the same 1098 form. Additionally, the insurance paid is included on this form. Should I just divide these in 2 and report half of each for the rental and in my deductions?

I put 100% for the rental property because I bought a lot of tools and supplies to make minor repairs to the other side in 2016. I don't want to have half of that allocated as personal use, as it was all used entirely for the rental side.
