Methodology. Insurance: SC DOI rate-filing baseline (~0.45% of property value), uplifted by per-ZIP NFIP claim density, growing 7.5% / yr. Property tax: assessor millage on assessed value, growing 3.5% / yr. Cooling: Charleston-area household baseline, growing 4.5% / yr at NOAA's SC cooling-degree-day trend. Estimates only — actual costs vary with carrier choice, mortgage escrow practices, and weather. Recomputed nightly. Data sources: FEMA OpenFEMA · SC Department of Insurance · NOAA Climate.gov · Tri-County assessors.
