My client purchased a 4-plex (4 units on one building, purchased all as one transaction) and rents out each unit individually - can i combine the income/expenses on schedule E as one property or do i need a schedule E for each unit in the 4plex? 

Form 1098 was also sent as one form for all 4 units, if i need a separate schedule E for each unit, how would i split this up in the system as it only allows you link the 1098 form to one schedule E? 

any assistance is appreciated.
