Biggaz13,

The LLC structure is totally individual, depending on how many houses you purchase and how you want to protect yourself. (Speak to your accountant about this)

In regards to the ITIN question, I was under the impression that an ITIN is still required in order for individuals to complete a US tax return every year. I will be visiting the US again next month and I will finalise it all when I am over there as I have understand (and you have pointed out) this is a more complex application process.

Streamline, my contact at Wells Fargo needed the LLC set up documents as well as the LLC operating agreement in order for me to open the business bank account, so I would say that the LLC is an important part for setting up the business bank account.
