20 years ago I was able to split rent for a tiny concrete windowless-basement-bedroom for 450$/mo, trimmed my grocery/cleaning bill down to 100$/mo by eating nothing but rice, beans, and frozen vegetables, 120$/mo for a phone and internet (which I consider essential), and another ~80$/mo in bus tickets. That's ~750$/mo.
Nowadays, when two bedroom appartments in small remote cities are going for 1600$+, I'm guessing splitting rent is much closer to 800$. That doesn't leave enough money for food, transportation, and communication methods. Heaven forbid you get injured or sick.
