+1 about South of Brazil. USD 1k with BRL as it is, it's more than enough to get an entire middle-class apartment for yourself and pay for all utilities in any neighborhood. (I'd not recommend largest southeast cities because you could feel "back" in L.A. traffic).
As I've experienced trying to rent a place in SF, in Brazil even largest cities are _waaay_ easier. You'd have to talk directly to an owner (since it would be difficult for you to prove income) but it wouldn't be a problem finding them and renting for less than a year.
Language will not be a problem, there's a startup scene if you feel like talking shop, and plenty of places to see and visit. You'd have all the infrastructure to stay for a long time.
