No state income tax

South Dakota levies no individual or corporate income tax whatsoever -- a real, substantial, genuine advantage that applies in Keystone as statewide.

A statewide-average property tax rate

This record carries forward South Dakota's own statewide average effective property tax rate (~1.06%) -- no Keystone- or Pennington-County-specific rate distinct from that figure was independently confirmed this pass.

Real, disclosed elevated homeowners-insurance risk

Keystone sits within the same Black Hills wildfire-risk zone this project's own south-dakota.js record ties to the state's highest-cost ZIP codes for homeowners coverage (Buffalo Gap, Pringle) -- this record applies a HIGH_HOMEOWNERS_INSURANCE tag on that disclosed regional basis.
