LLC with long distance investment properties

[Ayano Itoh]

Hi, 

This might be a very basic question. I live in Los Angeles, California and have an investment property in Texas. 
If I were to start an LLC, do I have to have an address in Texas? Or can I use an address in California?
In general, without having an office, what address do people use for their LLC??

What are the tax benefits of having an LLC?

I’d love to hear from people who are doing long distance investment and in the similar situation as me.

Any input would be appreciated! Thanks!
