Roommates after freshman year of college

Let's talk about roommates. Remember freshman year? Think back. Most colleges and universities assign freshman roomies. I blogged about it last Spring. Well, now I'm talking about roommates after freshman year and beyond. Your Gen Y kid gets to choose.* Last week a friend of mine shared that her son called to just bounce some thoughts off her about what he was thinking.

*Please note: This is not a time to insert yourself as a parent! This is their choice and decision. But if asked, well then. Otherwise just be a sounding board!

It made me think about those times when my kids called and did the same:
Do I live with just one person or
Do I live with three, four, or five?
Do I try to go for a single?
I really like these guys but they're all a bunch of slobs and I don't really want to live in a pig stye for a year.
I get along great with her, but she has a boyfriend and I really don't want to "live" with him too. Or
She has a boyfriend and I know since he lives off campus, she'll be over there most nights, so I will be virtually living by myself.
I know it'd be really fun to live with him, but I'm afraid it'll be too fun and I won't get anything done.
A couple of different guys have asked me to room with them and they're from totally different "groups," how do I say "yes," to one guy and "no thanks" to the other, because we can't all room together, it wouldn't work out.
I want to live in housing that has a kitchen, so I can cook my own meals, if I live with her I know I'll be the one always doing the dishes, what should I do?

Some of my throw back responses were along these lines:
Do you want to live on your own? Will you be lonely?
If you're thinking about more than one roommate, do you get your own room? If not, how are you guys going to decide who actually rooms with whom?
Are several girls too much drama? Are several boys too much like a frat? Is that a bad thing?
What about the boyfriend thing? The girlfriend thing? Really think about that. You may feel that it's a bonus to have a "single," but then again you may really want a roommate.
If there's a kitchen (or a private bathroom for the suite), how are you going to keep it clean? What are you going to do about food purchases? Your own separate shelves? Purchase together? What's mine is yours and yours is mine?
Things to think about.

Bottom line with roommates: Expectations should be vetted BEFORE moving in together. I think it's probably safe to believe that if people go into a roommate situation expecting that everyone is going to get along then most likely, they will.
