Lower spending changes the math fast
When living costs drop meaningfully, the required portfolio target can fall with them.
That is why Chiang Mai remains a popular reference point in location-flexible FIRE planning.
Keep the plan durable
The lowest possible monthly budget is not always the most sustainable one.
Healthcare, travel, changing neighborhoods, and the desire for more comfort often raise the long-term spending floor.
Use honest assumptions
If the version of Chiang Mai you want includes strong internet, air quality workarounds, flexible travel, and private healthcare, put those into the model.
That honesty is what turns a fantasy budget into a real FIRE plan.
