It sounds to me like you already have are a LLC and that your questions is more regarding Argentina and RE laws? If I was you, I would do as much research on line as I could possibly do. I would contact a RE Agent in Argentina and ask them what you need to do and what is expected and last but not least I would contact people who have also invested in Argentina and ask them about their experience. One great forum is http://answers.yahoo.com/ and http://www.tripadvisor.com/ForumHome, yes, Trip Advisor is mainly for questions about vacations BUT people from all over the world get on that website and many other types of questions are answered there. It has been very useful for me when I need information about other countries.
