TIP: Free housing and get paid to sleep.
My brother had a job at a home for people who had head injuries. As part of the safety regulations for the home, it was required that an able-bodied person would be available overnight to assist the residents in case of fire or emergency. That person need not be awake, but just ready to help if the need arose. With some first aid and fire safety training, my brother not only got a free place to sleep overnight, but he got paid minimum wage for sleeping there!
