# Calculators for the decisions this campus raises

Each tool shows its formula and the source and date of every default. Change any input; the results are illustrations of your assumptions, not forecasts or appraisals.

- ## [School capacity and parking](https://325southchurch.com/tools/school-capacity/)

  How many students the two buildings hold at a chosen floor area per student, and the parking the City requires for that school.
- ## [Charter developer underwriter](https://325southchurch.com/tools/charter-developer-underwriter/)

  Project cost, annual rent and rent as a share of a charter school's revenue, against the 12-15% target and the 18% ceiling, with property tax by occupant.
- ## [Property tax by occupant](https://325southchurch.com/tools/property-tax-by-occupant/)

  Which owner and occupant structures are exempt from South Carolina property tax here, on which statute, and the annual bill for the ones that are not.
- ## [Buy or build](https://325southchurch.com/tools/buy-or-build/)

  This campus bought and adapted, against the same campus built new on land near downtown: cost ranges by component and months to occupancy.
- ## [Rent a purchase needs](https://325southchurch.com/business-cases/education-facility-investor/#threshold)

  The rent per sq ft an education or institutional tenant must pay for a purchase to work at a chosen cap rate, triple net or full service, and what a charter school's rent is worth to an investor.
- ## [Private school enrollment](https://325southchurch.com/business-cases/private-specialised-school/#enrollment)

  The students a private, Christian or specialised school must enroll before owning a campus works, at its own tuition, against how many the campus holds.
- ## [Training seats](https://325southchurch.com/business-cases/career-technical-training/#seats)

  The seats a training program must fill all year to carry leased flex space or an owned campus, at its own tuition and program length.
