I know both Costa Rica and Belize are very popular for ex pats and, surprisingly, I just read recently that Nicaragua is as well. 

Would I be filing as "Wholesale Trade, Real estate/rentals leasing, education, information, professional/technical services, or "other"?

Regarding the stock market- While we like the returns in our portfolio we always hedge our bets and only purchase in round lots; then use a straddle strategy to sell covered puts and calls to day traders.

This is an REI forum and guess what the traders on another forum have to say about real estate? 

For ex through ally bank you can open up a checking account in 5min without speaking to anyone and be ready to go.

Maybe this is the trader in me seeing this as an arbitrage. 

But, if you don't do this for a living, it isn't a material percentage of your taxable income, you don't expect to do it again any time soon, it's probably not a trader or business. 

But do you have enough knowledge/experience to be on the other side of a currency bet against, say, a currency-trader like George Soros? 

I get 1 lawsuit from Detroit landbank, and a lot of violenciens from the city, for ex i had a tenant growing mariuana plants in my basement, and a lot of other stuff.Now i finded a new PM that has everything under control, and its working fine.So a lot of headeache, but it was worth it, and i also bought 3 houses in Missouri and now the first in Chicago.I only read 1 book, and did not find out anything, just bougt and hoped for the best, which is kind of stupid and i payed the price, mentally and economic.

And I guess you'll have to figure out if your in it for long term investing for retirement/wealth, or if you're gonna try to be a day trader.
