I think $12k is doable. The thing is though, even if you're in a low-COL country, other things can add up - flights, travel insurance, vaccinations, visa runs. Taking into account these things, I think it's still possible if you live reasonably frugally, but there won't be much room for Western comforts / luxury. So perhaps the question is whether to tough it out for a bit longer in your current work, or would you prefer to rough it in a foreign country. Different considerations, different challenges. Personally, I can relate to your wanderlust, and hope to hear updates on whatever you decide to go with. :)
