First property banking

[Kate Jones]

Hi everyone. I am a 20 almost 21 year old. I am looking to buy my first rental property within a few months. I understand I need to have my business and personal bank accounts separate. I have a few questions.

-When you bought your first rental property, when/how did you first establish your business? 

-Since this will be my first property ( I am house hacking), will I be able to put this under a business even if I buy my next property a year plus later? 

-Suggestions on banks to use? Good or bad? I am part of Capital One and my partner is part of Chase. 

-Can someone give me pointers on a chronological order regarding to when you established your business (how long before your first purchase), when you set up a bank account for the first property, etc?
