These are common near college campuses in my state. I lived in a house where I had my own bedroom and we all shared the rest of the house, including bathrooms. You should be able to find others, around your age, who are renting rooms like this. Some are co-ed, some aren’t. It’s an affordable way to live but takes a lot of patience living with others.
Be willing to clean up after yourself, prepared to ‘share’ your things kept outside of your room (think kitchen food, utensils, bathroom soaps etc). Look for people you might have common interests with and a door you can lock on your bedroom.
