Expenses.

Before I say anything else, I'll say this: Make sure you realize how much of an investment it is to move out of your parents' house.

The obvious: You'll pay your own bills. There's electricity (and, possibly, gas), internet, cable/sattelite TV, water, sewer, etc.

The not-so-obvious: Right now, what do you own? Do you own your bed? All of your furniture (dresser, etc.)? Do you own a couch/futon/etc., or will somebody in your new place own living room furniture? Does somebody have a microwave? What about pots and pans? Do you actually own plates, bowls, glasses, silverware? When you do move out of the place with your two friends, will you have your own silverware, dishes, and cooking utensils? A TV stand/entertainment center, a bookshelf, a coffee table?

Now ... What will all of that cost?

Now, I've never really had a "roommate" but once, and he moved in for a few months after I had already lived alone for a few years, but I would imagine that exactly that would be the biggest issue: What do I have, and what do I need?

Another thing: I'm sure you trust your friends, as you probably should. BUT ... What do you have to protect your belongings? Not just from break-ins and such, but do you have a safe, a lockbox, or some sort of protected enclosure to hide your precious belongings in? Jewelry, important papers, finances, insurance, SS card, birth certificate, stuff like that. Something safe from burglary and fire.

Apart from all that ... It's always good to get out from beneath the safety net that is your parents' house and venture out on your own. It teaches (forces) responsibility, financial and otherwise. It teaches (forces) self-reliability. It teaches (forces) one to deal with other people on a daily basis, people that they can't really get away from, people that they may learn not to like. You may learn that, once that initial lease is up, you can't stand one or both of your roommates. But that's something you'll have to deal with as you get older and go through jobs and careers, you'll inevitably not like everybody you have to encounter on a day-to-day basis, and it's best to be forced to deal with them at home (on a temporary basis that you'll have a choice to get out of in the future) than wait until later and have no experience with it.

I'd say go for it. Get out on your own, man, do yo thang. Just be prepared.
