Schedule E for House Hacking 4-Plex

[Alex Christie]

I've searched with no luck finding the answer to what must be a common situation:

Say I have a 4-Plex, each unit with 2br/1.5ba. I rent three units and owner-occupy 1 bedroom of one unit while renting out the other, what would my schedule E look like? Is that 4 rental units with one being smaller than the others because it does not include my personal residence space? How would I divide the unit I live in between myself and the roommate for tax purposes?
