Separate Bank Accounts

[Nicholas Kitchen]

I want to get an idea of how people organize their bank accounts. I have 2 rental properties, looking at a third - a duplex. Right now, I keep both rental properties in separate bank accounts from each other, as well as my personal accounts separate.

1) At what point do you start to commingle these accounts (if at all)?

2) When are you "big" enough to use money from other properties to "borrow" (if you will) for a down payment for another property, for example.

3) At what point do you need to start thinking about putting these properties under an LLC or DBA?

Thank you for your time and input!
