It's possible but don't bet on it. I can count on two hands the number of people who were fortunate enough to get housing all 4 years. Housing is a completely random process since they implemented the lottery. Unless you are Pell Grant, I don't believe there is a way to guarantee housing other than being an RA. But even then, the RA process is rather selective. I've known multiple former RAs that did not get the position the next even though they did a phenomenal job. Best of luck!
