llc - confused on personal account, etc

[Rocco Swinney]

Hi All - i appreciate the help! As im really trying to obtain an llc, but confused on a few parts. Was hoping someone might know

1. Id like to keep a few rentals under my name, but any future ones have under an llc i create

Do you think this could cause any issues from an insurance standpoint in terms of them not wanting essentially two separate policies for me? 

Since i need a new ein for my llc... do i simply file this with my personal tax return or with having a new ein number - i need a completely different tax returns each year?

The other piece im unclear on is from my understanding you dont want to mix your personal cash with the llc. So if i have say 50k i want to move to my new business checking account for my llc then how would you do this without being tied to your personal account where the funds are?
