LLC questions for investing out of state

Hi folks,

I'm planning to purchase properties out of state, and plan to form an LLC to hold them. I might purchase properties in multiple states. I have some questions:

• 1. Does it matter whether I form the LLC in my home state, or in the state(s) where I will be purchasing property?
• 2. If it doesn't matter in which state I form the LLC, should I form it in a state that has the most favorable tax codes, even if that's neither my home state nor a state in which I'm going to purchase property?
• 3. Will the LLC need to pay taxes in the state where it's formed; in my home state; in the state(s) where I own property; or any or all of the above??

Thanks!
