Why do I pay on August 1st when my child moves in on August 13th?

In the past, we would collect the total owed in 2 equal installments of of the lease contract amount(August and January), similar to how you pay your tuition. However, many residents and parents asked for a 12 month equal installment plan. So we now divide the total for the lease term into 12 equal installments due on the 1st of each month (August-July). You are simply paying off the total lease term owed.
