Determine various avenues for advertising the type of housing you have available. Many college campuses have bulletin boards in high traffic meeting areas, such as the student unions, food courts, the student laundry and various areas in the dorms and classroom buildings. If you have the money, you can also advertise in the school paper or local newspapers.
Decide what kind of roommate or roommates you want. Depending on the amount of space you have, you may search for more than one roommate. Also, you may want to restrict the applicants to be same-sex only, particularly if the space doesn't afford much privacy.
Calculate how much you will charge your roommates. Split the rent and all common expenses equally. You also can determine a set amount to charge for both rent and bills so your roommates will know exactly how much money they need each month.
Design your advertisement. Flyers can include more information than you might include in a newspaper advertisement. Describe how many roommates you need, what sex they must be, the costs required and what will be included, if anything, in the rent, such as utilities, Internet and cable. If a washer and dryer are available on site, if the place is fully furnished or if there are any other added perks like a swimming pool, hot tub or big screen television, it's a good idea to include these in your ad to entice more potential applicants. Include your name and a phone number that includes an answering machine or voicemail.
Set up interviews with each candidate. Get to know the people to determine if you're compatible. If you're lucky, you might draw some people you already know or have a lot in common with. Ask questions about income and other relevant issues, and be prepared to address their concerns.
