Should I open a Business Account when house hacking?

[Jose Batista Abikarram]

Hello BP! I'm house hacking my first property In Rochester NY and basically trying to see your opinions on the following questions/topics. I know doing an LLC whole house hacking is not a good idea based on other post but I'm still wondering about these two.

1) Can I even open a business bank account without an LLC and have all my income and outflows from that account? If I can do you think is worth it?

2) When doing business bank account would you go with a big bank (chase, boa etc), online bank only (axos, azlos,etc) or local credit union?

Thanks!
