Advice on software used for MultiUnit Management

[Bojan Rajkovic]

Hello Everyone, I'm new to the group and posting for the first time. I currently self manage 2 townhouses from out of state (located in Kalamazoo, MI but i live in Chicago) as well as a summer lakehouse that I just purchased for pleasure, but will begin to use for AirBnB/Vrbo next summer. I'm in the process of bidding and hopefully finally owning a multi-unit (4 unit) building in Northwest Indiana. 

I am familiar with calculations, financing, etc. given that I have been a financial advisor for over a decade, but what software, apps, websites do you recommend or prefer to keep track of expenses, income, etc.? 

Thank you in advance!
