I have dealt with other forms of investment such as 401k, stocks, forex, and hedge funds, but believe me when I tell you: I am now hooked on real estate!

Currency risk, the chance of being sued, finding a good team (especially a good property manager), not knowing the market in terms of good areas/streets to purchase within, having to rely on others people’s opinions to a certain degree (e.g real estate agents), and the general risk of distance – if something goes seriously wrong, not being able to be there in times of need.

Each state would have build its own military, its own currency, its own FBI, CIA, white house staff..redundancy and waste! 

You may have a currency risk though.

Canadians with their exchange rates on currency have cooled off some buying in the U.S. but other countries have heated up investing here.Lot of people in CA are willing to pay low caps because simply they do not need the money.

Of course China can just deflate their currency by 25 percent, making the tariff a moot point.

Stable currency, 5.

I currently launched a corporation which I founded with different intentions, but being a international multi-level marketing company which taught people how to trade the forex and binary option markets we unfortunately never got if off the ground as intended and at this point of my life I'm getting better on knowing when to "Hold em and when to fold em" so to speak..

Finding trustworthy people to manage it, and currency/language barriers.

For ex.
