Not sure if you will see this, but I have used QB since 2013 for our rentals. We have 23 properties. All you need to do is set up the Classes.  Then each class has it's own income and expenses.  You then use the P&L By Class report to do your tax return and anything else you need split up by property.  It's SOOOO easy.  I'm a CPA - and I use this for my clients as well - along with others in my firm. I cannot imagine not having QB for all this activity.
