1 Checking and 1 savings account is all you need.

The first one to hire would be the accountant.

I opened individual interest-bearing savings accounts for each tenants security deposit.To be clear, are you opening a separate bank account for each security deposit?

Less bank accounts results in less check books, less debit card numbers, less account numbers that you have to track.best of luck.

I'm having a hard time trying to find a bank that I can open a business account with online.

Quote from @Lieren Schuette: What online savings account is everyone using?  

It will auto download bank and credit card transactions, give you reports by account, category or property in any form you want. 

You can have an email for each account and you should be able to set your phone up see multiple accounts at once should you get inquiries or messages.Just log into each account to make updates and price changes.

I personally have a separate account for each property I own.

But is there a Chart of Accounts that anyone could share?
