2 properties on the lot. One house I live, one house is rented

I live on a lot with two houses, one parcel. We get one single tax statement, so the property taxes covers both houses. The houses are numbered 10213 (the house I live in) and 10217 (the rented smaller house), They are not attached to each other. The main house (10213) is 1680 square foot and the rented house (10217) is 690 SF, which is about 41% of the total property.  Utilities and all other expenses are separate, except property taxes. In the rental property section do I list the 10217 as a rental call it a Duplex/Multi-Family? And how do I show the property taxes? Help is appreciated.
