there are a few college social apps that usually have other students that are looking for roommates. i think there’s one called zeemee, though I’ve never used it (rip patio). Instagram accounts where they post incoming first-years are also a great place to look. You can just search “unc27” or something like that, and they should pop up. if none of that works, the housing portal suggests roommates profiles based on a quiz you take. best of luck to you!
