My Two Cents on retirement
Biggest variable if you retire here are health costs.
Never need hospitalization, die suddenly at 90 preferably from trying for that second pop with the 20 year and you can live well on 100 k a month. I know a number of heads in Pattaya who actually manage on their social security checks.
Get sick, need procedures, days possibly weeks in hospital and lengthy follow up therapy without insurance you can quickly have 6 and 7 figure balances on your MasterCard.
Key is having insurance where as we know premiums are dependent on age, coverage, deductibles and the small matter of whether you have preexisting conditions.
Not at all cheap if in your seventies. Hospital costs have gone up more than most other items I'm aware of during my 20 plus years here. In contrast occupancy costs not if buying but if renting have moved very little. Increases in food, depends where you eat, you can still enjoy a plate in Villa for less than a 100 baht, Increases in entertainment, go go's yes but oilies little changed, still about 2 k for an hour.
Changes in exchange rates can be significant, the '97 crash sent the $ to 50 from 25, now back to 31. Sterling from over 80 post crisis to 40 now. Going forward the trend would suggest a strengthening of all Asian currencies I. E. Less baht for your home currency. Lots of chatter around a weakening dollar.
Ok so WTF am I saying. In my opinion Thailand is the best country in the world to retire in, the people the food and the girls, just don't get sick unless you are covered by insurance or have your own resources.
