Getting a roommate is a great way to reduce your costs but perhaps you should have someone you already know in mind and be sure in advance that sharing will be beneficial and work out long term. Getting roommates through craigslist or newspaper ads may be risky since you are living with a stranger. Should you buy a 2 bedroom that's over your budget on your own and have no one to share it with you could be in over your head and hurt your financial status & credit report. Maybe rent in JC first so you can get to know some people you'd be able to live with happily and then move forward.
The other big question is, are you comfortable being a landlord/roomate?
Best wishes, and let me know how it works for you!
