Cost of Living & Housing in Folly Beach
Folly Beach runs solidly into seven-figure territory for single-family homes, with a real coastal cost premium on sales tax and homeowners insurance -- and understanding South Carolina's real, two-bracket income tax alongside the island's genuine short-term-rental economics matters before budgeting here.

Learn moreHousing: seven figures for single-family homes, a real spread across sources
Sources disclosed a real spread rather than one clean number: Redfin cited a $961,924 median sale price as of May 2026 (down 3.8% year over year), while Zillow's typical-home-value measure ran considerably higher at $1,289,746 (down 1.4% YoY) -- two genuinely different measures (realized sale price vs. estimated value), not reconciled into a single figure here (base record). A separate snapshot cited $1,037,500 (up roughly 1% YoY) and an April 2026 figure of $1,224,500. More attainable entry points exist for condos and smaller properties, cited in the $700,000-$850,000 range. Whatever the exact number, this is a solidly seven-figure single-family market, not a budget coastal option.
South Carolina's real, two-bracket income tax, plus a real coastal sales-tax premium
South Carolina is not a no-income-tax state and not a flat-rate state: under Act 110 (signed March 30, 2026), SC taxable income is taxed at 1.99% up to $30,000 and 5.21% above that, with Social Security fully exempt and age-65/retirement-income deductions coordinated (not additive) up to a combined $15,000 cap (base record). Folly Beach's combined sales tax rate is 9% (6% state + 1% city + 2% special district) -- the highest combined rate among this dataset's five-market SC Tier C batch, a real, disclosed coastal premium over the inland markets in that same group.
Property tax and the owner-occupied assessment gap
Charleston County's average effective property tax rate is cited in a real, disclosed range of 0.32%-0.53% depending on methodology (base record). What matters more for many buyers here is South Carolina's Legal Residence Exemption: an owner-occupied primary residence is assessed at just 4% of fair market value, versus 6% for a second home or investment property -- a real, meaningful distinction given how much of Folly Beach's housing stock functions as vacation rental or second-home property.
Homeowners insurance: real coastal cost pressure, not precisely quantified here
South Carolina's statewide average homeowners insurance premium runs $1,969-$2,004/year, but Folly Beach-specific dollar figures were not independently confirmed this research pass -- a genuine, disclosed gap rather than an invented number (base record). What is well documented: Folly Beach sits in FEMA-designated flood zones that carriers price for storm-surge and tidal-flood risk, 2026 reinsurance cost increases are being passed through specifically to coastal ZIP codes, and beachfront Zone 1 properties may need a separate SCWHUA wind policy if a standard carrier excludes wind coverage.

Key takeaways
- Single-family home prices run solidly into seven figures, with a real, disclosed spread across sources ($961,924 Redfin median vs. $1,289,746 Zillow typical value, as of 2026); condo entry points run $700,000-$850,000.
- South Carolina's real Act 110 income tax (1.99% under $30,000 taxable income, 5.21% above) applies here as statewide, with Social Security fully exempt and coordinated 65+ deductions capped at $15,000 combined.
- Folly Beach's combined 9% sales tax rate is the highest among this dataset's five SC Tier C markets built together -- a real coastal premium.
- Homeowners insurance carries real, disclosed coastal cost pressure (FEMA flood zones, rising 2026 reinsurance costs, possible separate wind coverage) that was not precisely quantified this session -- get an address-specific quote rather than assuming the SC statewide average of roughly $1,969-$2,004/year applies.
