Investors & landlords

What makes this more complicated is when I am there I do not think I am allowed to consider it 2/3 rental since I am sharing the Living/dining room and the kitchen.   I think best case is 4 out of 8 (if I count the baths as rooms so 4 rooms (2 bed and 2 bath) rented 4 rooms personal (1 bed, 1 bath, living/dinnig room and kitchen).
