I just want to follow up on my post and a great reply I got back. Mostly, I'm surprised it didn't get more traction in that I would've guessed that a lot of other guys are strategizing their long term overseas adventure/relo.
I will readily admit that 30k may not be enough to set up an income vehicle for living abroad for most but not all. I'll explain:
In a lot of the third world 30k has the purchasing parity of 3-4x what it does in North America (and N. Europe). That means you can get more - a lot more- for your money overseas. That means that you could open or buy a business that would satisfy your cash flow needs --- in fact many guys- specially retiring military- do just that. This extends to property as well.
The hangup is that in many cases you should be fluent in the local language, be very hip to the local laws and culture (or get a dependable partner), and be ready to be hyper-vigilant over your inventory, receipts, employees, etc.
The other thing is to work abroad: now know that I've done it - both high and low. As it happens,the most desirable places to live and bang are unfortunately the same places that are a bitch to earn a living in. There are many threads written - and to be written -about long term strategies to turn that truism upside down e.g. earn an oil/gas dependent tech degree and learn a foreign language.
But in the short term your options are really limited: work/sell/trade online, teach English, import/export. I can't discuss them all here but I'll tell you that they are all viable. The simplest - teaching English - is a short-term solution (we can discuss) and again, the truism holds: the most (bang lifestyle) desirable locations pay the worst.
My own ? about trading online was skewered - fairly and politely- by samsam: 50 bucks a day day or swing trading is NOT easy for a novice trader. I'll be lucky not to lose more than x% of my principal as I learn my way. The advice - which I am taking as I speak- is to learn, read, sandbox trade, start slow, etc etc until you can see you're making small profits then try to make them consistently.
But for me, I'd like to set up a cash cow up here - it's safer and more predictable. You can knock NAm society for all its many faults but as soon as you get a few dollars together --that you'd like to make into more dollars-- you can't help but love our systems of laws, property rights, and financial infrastructure that works. I don't mean necessarily in a macro, philosophical way --- I mean when it's YOUR own private little nest-egg your trying to grow and protect.
One of the best ways ,given a little capital and good credit is , as samsam suggests, to flip properties. As it happens, I have accidentally backed up into such a deal and hope to soon have close to double my $ in the kitty

Flipping too has its challenges. In fact, there is no shortage of ambitious, smart, and often cutthroat guys all over competing with you. On the other hand, there's a lot of real-estate...
BTW, I disagree that ARM's are such a great threat. I foresee rates rising slowly - if at all- for at least the next 3-5yrs. Managing rentals from abroad is now, thanx to tech, much more feasible. Tenant selection is key as is having help - locally- to help. Many properties - speaking of FL- hereabouts can kick off 400-900/month depending.
Soooo, for me, the answers are still out there -- I'll keep an eye on the skyline; you never know what the winds will blow in: this is hurricane country.
