Difficulty: Moderately Challenging
Step1
Live with your parents. This solution isn't for everybody, but some people find living with their parents is a great way not to pay rent. Of course, this requires that your parents are okay with not charging you rent. Helping around the house or contributing in other ways can help make them more comfortable with your new place.
Step2
Get a scholarship. Some scholarships will give you free room and board at college dorms or other on-campus living. This way, not only do you not have to pay rent, but you get a free education too.
Step3
Work some place that includes living arrangements. Many amusement parks and other services provide rent-free accommodations for their workers. Inquire about the costs of employer provided living before-hand so that you don't end up paying rent.
Step4
Stay in a shelter. For those with no other options, a shelter can provide a safe place to eat and sleep. Homeless shelters don't require you to pay rent, although they may require that you have a job or a valid ID.
Step5
Try couch surfing. Couch surfing is a relatively new phenomenon that applies to travel. Basically, people agree to allow travelers to sleep on their couch if they're in the area. This is set up though online communities of couch surfers, who decide dates, times, and other necessities.
