I work part time nites and am currently living with his parents. Yes- that is a horrible living situation. However, they provide free child care. I will be moving in about 2 weeks and have a teen age sibling who will live with me.
Many people make it on much less.
I am trying to do more of this and less of third shift work. I make good money reselling it's just a matter of being commited and finding the right stuff. It's also a matter of trusting God because to do it full time I would have to quit my regular job. It's scary to not have a steady income. I am working towards a homestead lifestyle.
