i agree with the communication. The food is very westernized in Phil and it's starting to show with all the plumpies walking around. Much healthier choices in Thailand. Crime, you are on point. Thailand you can walk any street at any time and not have a problem. Amazing.
If you like eating out western food, drinking a lot, and women, expect 100k to 1 million baht per month.
If you don't drink, like to cook, or find cheap open markets, and dont drink more than a six pack a week, a few women a month, you can do 45k to 70k baht per month.
This is Pattaya prices.
If you move to more rural areas of Thailand, prices drop.
If you move to an area with more westerners, prices rise.
More rural means less people that speak your language and will depend more on Google translate.
You should come for about 6 months to decide what you want, what you are willing to accept, if you like the weather and heat, language barrier acceptance, financial abilities based on your finances, female/relationship expectations, food acceptance, etc.
Everyone is different and expect or accept much different things. Test drive. I just did mine for 9 months and it's been a wonderful learning experience.
