Self managing 12 new properties

[Leah Spurlock]

We are new investors to rentals/flips.  I have recently purchased 12 properties which 10 are currently rented.  I'd like to self manage these. I just want to make sure my financial tracking and bank accounts are the most efficient.  Currently, I have spread sheet for each property.  I have set up a business checking acct for all income and expenses, and a business savings for security deposits. I'd love to know how others are keeping their financial tracking efficient and easy.  Thanks!!
