Tax Liens on Property owed by a Foreign Entity

[Sarah Bella]

Hi all, 

I am starting to invest in tax liens. I am going the "Orphan Lien" route and looking into liens that did not receive a bid at the last auction. I have found several on some beautiful property lots, however, every single lien I have come across is on property owned by an investment company out of Denmark. Should I be wary of this?

Any advice would be greatly appreciated!
