Another option is an extended stay motels/hotels - you can find them in 600-700$ range per month. They are equipped with kitchens and has a minimum needed for a living - bed, bathroom, phone. Not particularly a dream place but you can rent it weekly, daily and not depend on anybody.
I spent 4 months at such place after arrival in Atlanta and I have a kid (which makes it more difficult 'cauz of limited space). Felt safe.
