>If you wanted to try something more exotic, you can do the digital nomad thing and rent somewhere in Thailand for ~$100 a month,
I feel like I should point out that getting something that cheap in Thailand is difficult and certainly will not be pretty. I have previously lived in Thailand for just under a year and then gone on to be a digital nomad for three years and counting, mostly in south east Asia.
Its pretty trivial to live on 800-1200/month in Thailand and I have known people to get it down to $500/month but there is a floor there that, to go under, you would likely need to move somewhere very remote that is likely to have an unreliable electricity supply and probably won't have an existing net connection or a telephone line for you to get access to the net. It would help to speak reasonable Thai too as you will be living somewhere well away from the touristy bits of Thailand where the English speakers tend to congregate.
Now, that isn't to say that its impossible. I know someone who, at one point, was living on the outskirts of Siem Reap (Cambodia) for $200/month total. $80/month of that was rent. Firstly, he is an extremely experienced nomad. Secondly, that involved living in an old wooden house with no airconditioning (Cambodia gets brutally hot) and walking across town to use the wifi at KFC. It worked for him because he was working on a book so he only required sporadic net access. He is also from the Philippines and grew up without air conditioning so apparently the heat and humidity was bearable for him. Personally I find not having aircon in the tropics a really quick way to take your productivity to zero. Thirdly, to keep his costs that low an enormous proportion of his diet was made up of boiled rice with token amounts of vegetables. When he went to KFC he would purchase a single piece of chicken so they wouldn't kick him out and so his diet contained some protein. Handy if you want to lose weight I guess but tightly restricting your vegetable and protein intake is otherwise not particularly healthy.
Anyhow, just wanted to point out that "rent somewhere in Thailand for ~$100 a month" isn't something you are just going to walk off the plane and arrange without making some very serious health and lifestyle sacrifices.
