Tax Lien Investing in the US as a Foreign Investor

[Izaak Behringer]

Hey BiggerPockets!

This is my first post on here but I have been quietly reading and learning a lot since I joined. Love this community!

I'm a New Zealander living in Norway and have recently been doing research and reading books on Tax Liens. I feel like I have a decent grasp on the subject but I am at a bit of a dead end as to how I can actually begin to invest... 

I have found a couple of online auction sites and have also tried to find info and experiences from other foreign investors but it's very limited.

Would appreciate any thoughts and/or past experiences from anyone :)
