A $1,544,076 median sale price (May 2026, Redfin, down 17.4% YoY) sits far above every other market in this six-market batch, including Daniel Island's $1.6M+ figure -- though the exact figure varies meaningfully by snapshot month given the island's low transaction volume, a real feature of a market this small and this expensive.
Real, disclosed extreme wealth concentration
Median household income was $213,594 in 2024 (already extremely high), but a separately cited AVERAGE household income of $411,440 for 2023 runs nearly double the median -- real, disclosed evidence that a small number of very high-net-worth households pull the average well above what a typical Kiawah resident actually earns.
Total annual homeownership costs run genuinely, extremely high
Total annual costs (property tax, insurance, and POA/special-district assessments combined) are estimated at roughly $30,000-$70,000/year for mid-range properties, and can exceed $100,000/year for larger oceanfront estates specifically -- a real, disclosed figure well beyond a simple property-tax-plus-insurance estimate.
South Carolina's real two-bracket income tax, restated at the local level
South Carolina's income tax is genuinely two-bracket and graduated (1.99% under $30,000 taxable income, 5.21% above, per Act 110 signed March 30, 2026) -- a statewide fact, not Kiawah-specific, but real context for high-income retirees and second-home buyers weighing overall tax burden.
Key takeaways
