Free seminars are complete scams. There's a reason why they're free. I can guarantee you that the seminar will not talk at all about buying real estate. Instead, it'll talk about how you should sign up for a PAY seminar (which is also a scam) to get the real information (that you can probably find on the internet or just by talking to a real estate agent). This is how those "Rich Dad, Poor Dad" free seminars work.
Seriously if you wanted to buy US property, why don't you find an agent that deals with these kinds of things and talk to them instead?
