Learn moreA genuinely second-home-dominated housing stock
68.7%-70.9% of homes on Kiawah sit vacant/seasonal depending on source -- meaningfully HIGHER than Hilton Head Island's disclosed 28.32%-39.1% range elsewhere in this dataset, real, direct evidence Kiawah sits further out on the resort-exclusivity spectrum. Of occupied units, 98.2% are owner-occupied.
Real, disclosed price volatility given low transaction volume
Median sale price snapshots genuinely disagree by month: $1,544,076 in May 2026 (Redfin, down 17.4% YoY), a separately cited $1,500,000 for the same period (Movoto), and an earlier $1.2M for November 2025 (down 12.5% YoY at that time) -- all disclosed rather than reconciled, since swings of this magnitude are a real, expected feature of a low-volume luxury market.
A real, structural property-tax detail for the many non-primary-residence buyers here
South Carolina assesses owner-occupied primary residences at 4% of value versus 6% for second homes, rentals, and investment property -- a meaningful, real cost difference given Kiawah's overwhelmingly second-home-dominated housing stock.
Key takeaways
- 68.7%-70.9% of Kiawah's homes sit vacant/seasonal -- higher than Hilton Head Island's range documented elsewhere in this dataset.
- Median sale price genuinely varies by snapshot month (roughly $1.2M-$1.54M+ across recent citations) given real, low-transaction-volume market behavior.
- South Carolina's 4% (owner-occupied) vs. 6% (non-primary) property assessment ratio is disproportionately relevant here given how few Kiawah properties are primary residences.
