LLC location in TX or AZ

[Robert Loree]

Hi. I'm looking to purchase my first properties in Phoenix, but I live in El Paso,Tx. I am approaching contract and would like to purchase with a LLC or transfer soon after purchase (lender says this is not a problem). There is a lot of conflicting information in regards to LLCs. Should I set up the LLC in my home state of TX or where the properties are located in AZ? Also is there a reason I shouldn't use legal zoom(or competitor) to set this up, or should I specifically reach out to a real estate attorney?
