If you're living with roommates, you have a whole new set of things to deal with. For example, you have to divide up all your expenses, and share a close quarters living space. The former can be easily managed with a service like Splitwise, and almost everything else just means you should have a conversation and set ground rules early on. Of course, if you just get stuck with a horrible roommate, there are ways to "evict" them, too. Photo credit.
