In your situation, LAY DOWN CONSTRAINTS. Do so early, and be generous. If it takes a while to figure out what your constraints are, be sure to mention them as they come up. I've lived in both party houses and highly-regimented 2 bedroom apartment agreements, and have discovered that the more active you are in the household, the more reciprocity you'll enjoy. Do not regret to do the dishes for any of your companions, and do not be afraid of using it as a bargaining chip along the road! That way, you'll find those that are true to your efforts. The reason I say this is: because it is way too easy for yourself and roommates alike to be lazy and to not spelunk into the cavern of each other's personalities, it is better to be like-minded, preferably on clean, solid ground, for the betterment of each other and others (i.e. guests). Personally, I prefer to live alone. Good luck to you OP. It will be a big change but you sound like a college freshman. :)
