I never had a particularly successful roommate…i.e., a person I liked very much by the time it was over…but that may be b/c I didn’t know then what I know now, and what I will tell you.
I wouldn’t, in all honesty, move in with friends. Just because you like them doesn’t mean you’ll like living with them, and then you’ll be out a roommate and a friend. It’s a lot easier to solve issues with people you’re not really tight with than it is to tell your good buddy that you’re ready to kill him b/c he keeps using all the toilet paper and never buying any to replace it, and borrowing your razor, and drinking all the soda in the fridge, and leaving cereal bowls in the sink without any water in them so that they get all gunky…etc., etc…
Figure out who buys what, down to the toothpaste. Trust me, it’s gonna get old if somehow you’re the only one buying toilet paper, milk, mustard, glass cleaner, dish sponges, trash bags, detergent, etc., etc. I’ve had plenty of roommates who just somehow never “get around” to buying their share of this stuff, or at least giving me money for it when I do.
I’d recommend getting a whiteboard and writing down any communal items on it, like the ones I just mentioned, and get into a habit ASAP of either giving your roomie the money for your share, or hitting him up for his, or making a rule where you buy/he buys/you buy/he buys. You’re inevitably going to share some stuff, so it’s best if you’re straight-up from the beginning that all of this stuff is communal and equally sponsored.
Also figure out who cleans the common areas and how often, and what your idea of “clean” is vs. theirs. Some people are fine with clutter, some aren’t. Some people think cleaning the bathroom means emptying the trash and wiping down the counters; some people believe it isn’t clean til every surface has been Soft-Scrubbed.
The more you decide and agree on up front, the happier you’ll be. Trust me. It only sounds anal if you’ve never come home to find that your roommate used the last of the laundry detergent and then didn’t even take their load of the dryer.
For the third time this month.
Roommates can be fun but it’s surprisingly hard to live with somebody you’re not related to or in love with; it’s not nearly as easy to overlook all the little stuff. Prepare yourself for a moderate amount of inconvenience and irritation even if you do your best to avoid it; a successful roommate situation is one where everybody’s willing to compromise.
