A call to the Secretary of State of Texas will give you the assistance for forming your LLC. I'm not an attorney. I do operate in TX with an out of state corporation though.
If you start a TX LLC you will need a registered agent. There are companies that provide this service such as National Registered Agents. They charge a minimal annual fee. My thoughts are that you would not want the subject property as the address.
If you start your LLC in another state, then you will need to register as a foreign entity. SOS of TX will help with that too. You will need a registered agent for that as well.
Not sure if you are doing this in your IRA? Quest is a custodian that is strong in the TX market. They provide good networking and consultation.
You will need non-recourse lenders, like B2R, or other private money partners.
The business in the market is good. The biggest hurdle is the human element. Make sure you have accountability in place. Trust, but verify anyone doing anything.
