Intro and Beginner LLC questions

[Shane Sitzman]

Hi, great forum! I'm excited to be here and excited about REI. I live in and am investing in Las Vegas. I am partnering with my sister and we are creating an LLC. My sister and I are both married. Should I include all four of us as members. I was thinking to include my wife so we can document and claim the days worked for the tax benefits.

Do I need a business license for the LLC? I was under the impression that i don't, however, I was told differently.
Also, Because I'm going in with family, we are drafting an agreement concerning shares and compensation. Does this have to be filed with the LLC paperwork, or is it something between us?

I'm going to employ a property manager for the rentals I'm buying. Do you see any issue with using the same person as property manager and buyers agent?

Finally, Banking. I understand that I need to establish a trust with the property manager to have funds available for repairs and such, however, for the business, do I need any type of special account at the bank. I see business checking and all that, but what is the difference between these accounts and a regular account in the business' name at a credit union (I talked to the credit union and was told they don't have business accounts, but they can put the business' name on the account)

I hope I'm asking decent questions. I've been looking for these answers and this is my first time using a social site.. hopefully you can help because I'm having difficulty figuring it out myself.
