> Where?
There's this thing, you may have heard of it, it indexes the World Wide Web and allows you to search that index free of charge. They call them search engines, a popular one is Google at https://google.com, but I presently prefer https://duckduckgo.com.
A cursory search using obvious keywords reveals that Cambodia is one such place, where one can apparently live in downtown Phnom Penh for less than $500/mo.
