Questions about forming LLC

[Bennie Overton]

Hey Everybody,

First time poster. I'm almost about ready to start jumping into investing, but I wanted to get my LLC formed first. Had a couple questions:

1) I know the whole purpose is to separate the individual from their business, but how deep do I need to go with this separation? For example, I'm brand new so I don't have my own office space yet. When forming my LLC, would it be ok to use my personal residence's address for now? Or should I use a PO Box? What about using my personal phone number? For now, I want to focus on rehabbing and possibly rentals later down the line.

2) I finally came up with a name for my LLC. I'll be both filing and conducting my business in NC only for the time being. After doing a search, my LLC name isn't taken in my state. However, doing a quick Google search shows that there is another LLC in Tennessee with the exact same name. Could I run into problems with this, even though we've formed our LLC in different states? Could I run into issues if I ever wish to expand outside of NC? What about problems with marketing down the road (i.e. I start making websites with my LLC name attached to it)?
