Non-Instructional Facilities (NIFS)

Q1: How do I calculate the discount for my NIFs?
Q2: How do I figure out if my NIF is urban or rural?
Q3: My NIF has classrooms. Do I still use the snapshot method to figure out the discount rate?
Q4: My NIF is located in a rural area, but the district is urban. How do I get a higher discount rate for my NIF?
Q5: To determine the urban/rural status of my district, do I count NIFs when figuring out if more than half of my entities are rural?
