1 or more LLC's recommended?

[Scott Kimminau]

Hello! 

I have 4 rentals in Missouri and 4 in Kansas. I've heard a number of different suggestions on whether an LLC is even needed and/or just have umbrella insurance. I've decided to go the LLC route for protection. I've heard 1 LLC property so my question is should I do one LLC for all properties, or 1 LLC per state (may be easier for tax purposes?) or one LLC per property. What have you all found to be best?

Thanks!
