Best country to work to build financial independence

I want to build my life up again but after being back in the states, it's gonna take forever here. I found a way to get me almost anywhere but I want to be a little wiser. What's the most affordable country to become closer to financial independence? Is it fairly safe? Even for a female solo traveler? What are the apartments like or other places to live like there? What should I be aware of before going? Forgot to add that I'll be doing remote work, too. So I'll be making USD. Thanks!
