I would rethink actually transferring the deed to a buyer if you are still on the hook for the note.

I'm curious about how they are able to convert your business credit cards into a cash line of credit while avoiding the high balance transfer interest rates.  

If it's possible still, it would be better for the grandmother to keep possession of the house and have the ownership transfer upon her death due to the step-up in basis the house would get.

In exchange, I’d be able to be sort of an intern or someone to help with boots on the ground here in AZ.  

Ownership of the Property:**The ownership transfer will be outlined in the contract.

In Lackawanna county (Scranton area) for example, I always recomend looking in the surrounding neighborhoods of Scranton in addtion, as the rental rates are the same or higher, the turnover seems to be less, the taxes, trash fees, transfer tax etc are lower, and the neighborhoods seem more stable for appreciation.

(I know the gist of all of this - but not the specifics... but enough to point it out to you...)So be aware that if you transfer the property to an LLC - your county will likely treat this as a transfer of ownership (like they should)... the LLC is completely separate from you - even if you are the sole owner.  

The Internal Rate of Return is just under 12% and cap rate and 6.52%.

Looking forward to legal advice for LLC opening. any referrals who have experience with international investors? 

It's basically the same in every state: the lease transfers with the sale of the property and the buyer has to abide by it.
