In lieu of getting roommates together or going it alone in the rental market or doing services for someone in exchange for living space, you might try just getting a room in someone’s house. Dunno about your area, but Craigslist has listings for rooms to let at least in urban areas; now that you have a car, you have a wider area in which you can check that out. In a situation like this, you would only have the homeowner and his/her family to worry about.
Regarding income, I seem to recall that the Mr Money Moustache blog had a couple of articles a few years ago about 50 ways to make $50k in a year without a college degree. Now I grant that most of that list isn’t doable, but just maybe you can get one or two ideas with minimal startup expenses that you could do where you live. Maybe your income isn’t $50k, but it could be enough to get off the floor. Have to start somewhere.
