Managing Multiple Properties

[Dylan Hoffman]

Question for all you experts with multiple real estate properties!!!

I'm in the process of buying my third property, and am starting to think about how I can create a holistic financial picture of my entire portfolio (rather than manage each property individually). Does anyone have any tips on how you've done this successfully in the past? I'm talking about things like cash inflows/outflows, tenant & lease terms, home values, etc.  

If this helps, it basically stems from the question I've been mulling over lately, 'if one of my property becomes vacant, how will it impact my other two properties, and how much of the cash flow from the other two properties can I use to offset the costs of the third?' So really focused on financial management across my portfolio here.

Tips / tricks / online tools & platforms / anything else are welcome :)

Thanks!
