Purchasing property while outside the USA

[Tom Kiem]

Hi, my wife (american) and I (australian) are considering a move back to the US. Neither of us have owned property there before.

We're wondering what challenges we may face, and if it's worth while to set up and purchase through an LLC

I work as a real estate agent in Australia and have a good understanding of the process and tax implications here, but don't know where to begin to find the answers we need for usa. 

Any advice will be appreciated. 

P.S. If it helps - looking to purchase single family home or duplex in Wisconsin.
