The way I would do this in QB, I would use desktop it is more fully functional and I can see no reason you would have to be able to log in from somewhere else. (it is also cheaper, a non partisan comparison of QBO vs QB desktop

(cost comparisons are at the end of the article))
Create a customer for the address, then a sub customer for the unit, then a sub customer for the tenant
124 some street
>> unit 1
>> >> Mary Smit
<< unit 2
That allows you to change tenants when necessary, set the old one to inactive (and the records remain) and create a new one
Set up a class for each unit, that allows you to track expenses (and income) per unit and you can report on them.
