AStar Rentals (AR) maintains an inventory of rental houses near Sharjah universities and leases those houses to student renters. This case describes their rental business process. AR agents—former marketing majors renowned for their fast-talking and flamboyant lifestyles—work with potential renters and sign the rental contracts for AR.

AR tracks its houses by city or neighborhood, and distance from campus. AR assigns one specific AR agent to each neighborhood to manage rentals for all houses in that neighborhood, but each AR agent may be assigned to multiple neighborhoods. AR cashiers collect the rent and are bonded for security purposes. AR tracks cashiers separately from AR agents, although both are identified by employee numbers.

AR sets rental rates to its student customers by considering such matters as number of bedrooms and age of the house. Additionally, AR applies a monthly rental surcharge to each house that depends solely upon its neighborhood designation; for example, upscale neighborhoods have higher surcharges and less desirable neighborhoods have lower surcharges. The same surcharge applies for the life of the lease. Every house has a rental surcharge, and all houses in a particular neighborhood have the same surcharge.

Prospective renters, usually students, contact AR to inquire about renting a house. When a potential renter contacts AR, a AR agent is assigned to assist him or her. That AR agent remains the person’s point of contact for as long as he or she continues to deal with Beach Rentals. AR records information on each potential renter as soon as he or she contacts AR to inquire about a house.

AR agents negotiate the rental contracts with the students. Each rental contract must last at least 6 months, and 12-month contracts get a 5 percent discount. AR also charges a damage fee that is due along with the first month’s rent when the rental contract is signed. The AR agent earns a 10 percent commission on each rental contract, and AR tracks the year-to-date (YTD) commission earned for each of the AR agents. Of course, the AR agents compete with one another to see who earns the highest commissions, and AR fosters the competition by giving an annual award to its “best” agent. AR finance itself through its owners and a few cases get loans from banks.

When multiple students want to rent one house, AR requires that they designate the primary renter—the one who will be responsible for paying the rent. All the student renters, however, sign the rental contract, and AR assigns a unique renter number to each occupant. The students may not change primary renter for the term of a contract. AR cashiers collect the rental payments (1) each month, (2) every six months, and (3) every year from the primary renters. AR records information concerning employees, house owners, bank accounts, and neighborhoods in the database before the renters are involved in any events.
