You will likely need a registered service agent with a physical address to be compliant with LLC laws in Texas. These companies may offer mail forwarding services but that can get pricy. Visit with a Texas attorney about filing in the various counties the best address. I suspect that listing your CA address would be fine for county land record filings and for property taxes. Again, pay a Texas attorney for that advice.
