Just about any bank can open a joint account. 

Local banks.

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

Realistically, one checking account and an accounting system will meet all your needs and keep your business better organized than 7+ bank accounts.If you want to collect bank interest from excess cash, add a savings account.

if you have an LLC and both properties are under it, you just need 1 operating account.If both are under your personal, 1 bank account specifically for the rental is enough for operating.Security Deposits should always be a separate account altogether.

May just be the accountant in me.

Quote from @Carlos Silva: Has anyone tried velocity banking?  

We also have a bank account at a smaller Chicago community bank, but there technology isn't as good to be honest.I think @Jonathan Greene's main point is don't step over dollars to pick up pennies. 

I'm working on getting my bigger pockets pro account finalized even though I've been a member for about 1.5 years.

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.
