Starting out an LLC?

[Dolev Shemesh]

Hello, 

I'm a beginner real-estate investor with few properties in my portfolio. As i'm trying to expand I was think about opening an LLC.

Will an LLC provide me with any tax benefits? what are some of the benefits (besides the obvious liabilities portion) of having an LLC?

Also - should I put all properties under the same LLC or separate those out to max out liabilities options?

Thank you for your help.
