Some schools and private housing units will waive or reduce housing costs if you become a residential manager. You will be required to answer calls, keep up maintenance, and address service issues.
Housing managers can maintain a work schedule that coincides with your academic schedule. Another nice benefit is that your work schedule is at your place of living.
Check the area's student housing units for information. They will likely put you on a waiting list that might be worth something to you in the future.
