South Carolina
The state that quietly assesses your second home at 50% more than your neighbor's primary residence, and never sends you a letter about it.
Why buyers look at South Carolina.
South Carolina has spent the last several years quietly building one of the most attractive retirement and second-home tax structures in the country, and most buyers have not caught up to it.
Social Security is fully exempt. Military retirement income is fully exempt, which matters enormously in a state with Parris Island, Joint Base Charleston, Shaw Air Force Base, and Fort Jackson. There is a retirement income deduction of $10,000 per person under 65 and $15,000 per person at 65 and older, which is $30,000 for a retired couple. There is no estate tax and no inheritance tax. There is no local income tax anywhere in the state, which distinguishes it sharply from Pennsylvania, Ohio, and Maryland. And there is a 44% exclusion on long-term capital gains, which is unusual and which meaningfully changes the arithmetic for anyone selling appreciated assets.
The state income tax has been on a deliberate multi-year path downward from a historic top rate of 7%. Reported 2026 figures vary across published sources, and the exact current rate should be verified with the South Carolina Department of Revenue rather than taken from any real estate website, including this one. What is not in dispute is the direction of travel and the fact that South Carolina ranks 29th on the Tax Foundation's 2026 State Tax Competitiveness Index, which understates the picture for retirees considerably.
Property taxes are genuinely low. The statewide effective rate runs around 0.55%. And that is where the most important sentence on this page begins.
The character of the state
South Carolina is three states, and they do not resemble one another.
The Lowcountry is the one people picture: Charleston, Hilton Head, Beaufort, Bluffton, Kiawah. Salt marsh, tidal creeks, barrier islands, live oaks, pluff mud, and a light that has kept painters in business for two centuries. Tuesday morning here is a golf cart, a dock, a heron, and a pace that genuinely is slower. Charleston has become one of the great food cities in America. Hilton Head is a mature, well-run island of roughly 39,000 residents with twelve miles of beach and an enormous golf and tennis infrastructure.
The Upstate is a different world: Greenville, the Blue Ridge foothills, Table Rock, and lakes like Keowee and Jocassee that are deep, clear, and genuinely spectacular. Greenville has quietly become one of the most livable mid-sized cities in the South, with a downtown that other cities send delegations to study.
The Midlands and the Grand Strand are their own thing again: Columbia, Aiken's thoroughbred country, and the sixty-mile stretch of Myrtle Beach and its 80-plus championship golf courses.
The thing that unites them is summer, and it is a genuine consideration. June through September in South Carolina is hot and it is humid in a way that a person from Colorado or Montana will find difficult to describe to their friends back home. The Lowcountry in August is not a season. It is a condition.
The trajectory
The state is growing steadily, drawing retirees and remote workers primarily from New York, New Jersey, Connecticut, and Massachusetts, and increasingly from Ohio and the Midwest. Charleston, Hilton Head and Bluffton, the Grand Strand, and Greenville are all absorbing that growth.
But the Lowcountry is growing faster than its infrastructure, and this is the forward question that most buyers do not ask. The corridor from Bluffton toward Hardeeville and Savannah is one of the fastest-developing stretches of the Southeast. Roads, schools, and water systems are being asked to absorb a great deal very quickly. A buyer looking at a quiet parcel today should be asking what that road looks like in five years, because in this part of the state, the answer is frequently "very different."
And there is a slower, harder question underneath it. Sea level at Charleston has risen roughly 1.3 inches per decade since 1921. Tidal flooding in the historic peninsula is now a routine event rather than a storm event. That does not mean Charleston is a bad buy. It has been a good buy for three hundred years. It means a serious buyer models elevation, flood zone, and insurance with the same care they apply to the kitchen.
Who is moving to South Carolina, and why.
South Carolina is a consistent net gainer, and the pattern is one of the clearest in the country.
The dominant flow is Northeast to Lowcountry: New York, New Jersey, Connecticut, and Massachusetts into Charleston, Hilton Head, Bluffton, and the Grand Strand. The drivers are the ones the state has deliberately engineered: no tax on Social Security, low property taxes, a mild winter, and a coastal life at a fraction of what the equivalent costs in Florida.
That last comparison is the one to understand. South Carolina's pitch against Florida is not that it is better. It is that it is cheaper to hold. Florida has no income tax, which South Carolina cannot match. But Florida's average homeowners insurance premium runs roughly three times the national average, and South Carolina's coastal insurance, while rising, is nothing like it. For a retiree living primarily on Social Security and modest retirement income, the total annual cost of owning in Beaufort County can be lower than owning in Florida despite South Carolina having an income tax at all.
The Upstate draws a different buyer: Greenville is pulling people from Atlanta and Charlotte, and the Lake Keowee corridor is drawing a serious second-home crowd that most national buyers have never heard of.
Military retirees are a large and distinct group, and the full exemption on military retirement income is why.
Why buyers choose it, and what they should know.
Social Security is fully exempt and military retirement is fully exempt. For a retired couple, and particularly a retired military couple, South Carolina's state income tax bill can approach zero. This is the single most underrated retirement tax structure in the country.
A 44% exclusion on long-term capital gains. Unusual, valuable, and almost never mentioned. For a buyer selling an appreciated portfolio or a business, the effective state rate on those gains drops substantially.
Property taxes are low, and the primary-residence break is significant. An effective rate around 0.55% statewide. Beaufort County, covering Hilton Head and Bluffton, runs roughly 0.43% to 0.65% on primary residences. Horry County, the Myrtle Beach area, is among the lowest in the state.
A 15% cap on assessed value increases between reassessments. Reassessments occur roughly every five years, and the increase is capped at 15%. In a market like Hilton Head or Charleston where values have climbed sharply, this protects long-term owners meaningfully.
No estate tax, no inheritance tax, no local income tax. Assets pass cleanly, and a resident in Charleston pays the same state rate as a resident in a rural county with no municipal add-on.
Golf density that competes with anywhere. The Grand Strand alone has more than 80 championship courses. Hilton Head has Harbour Town and dozens more. Kiawah has the Ocean Course. Aiken has thoroughbred country. This is one of the great golf states and it costs a fraction of Palm Beach.
Coastal life at a genuine discount to Florida. The Lowcountry is beautiful, mature, well-served, and materially less expensive to own than comparable Florida coast.
Second homes are assessed at 6% of market value. Primary residences are assessed at 4%. This is the most important sentence on this page. South Carolina's assessment ratio system means a second home or investment property carries an assessment 50% higher than an identical house next door owned by a full-time resident. On a $1.2 million Hilton Head house, that difference is not academic. And here is the part that costs people real money every year: the 4% owner-occupied rate is not automatic. It must be applied for. The Legal Residence application is due by January 15. A buyer who closes on a primary residence and does not file is paying the 6% second-home rate on their own home. The question every South Carolina buyer must ask their closing attorney out loud: has the Legal Residence application been filed, and by what date?
Flood insurance is separate, expensive, and effectively mandatory on the coast. Coastal flood coverage commonly runs $2,000 to $5,000 or more annually on top of a homeowners policy. This is a carrying cost, not a formality, and it is the number most buyers leave out of the model.
Hurricane exposure is real and it is annual. The Lowcountry is on the Atlantic. Hurricane season runs June through November. Elevation, flood zone, and evacuation route belong in the diligence, not in the "we'll figure it out" pile.
Charleston's tidal flooding is increasing, and the data is not ambiguous. Sea level at Charleston has risen roughly 1.3 inches per decade since 1921. The question a two-year owner asks that a first-time visitor never does: what does this street look like at a king tide, and has anyone actually gone and stood on it during one?
Summer is genuinely difficult. Heat and humidity from June through September, with the Lowcountry at its most oppressive in August. Electricity bills climb. Any buyer considering full-time residence should spend a week here in August before signing.
Public services vary enormously. South Carolina's poverty rate runs above the national average and public school performance varies sharply between suburban and rural districts. For a relocating family, this is a district-by-district question, not a state-level one.
The Bluffton and Hardeeville corridor is developing fast. Growth is outpacing infrastructure in parts of the Lowcountry. This creates opportunity and it creates traffic, and buyers should know which side of that they are on.
The year, honestly.
Spring is South Carolina at its best, and it is genuinely magnificent. March through May: azaleas, wisteria, the Cooper River Bridge Run, the RBC Heritage at Harbour Town, mild days, and the Lowcountry at its most beautiful. This is the season the state is designed for.
Fall is the local favorite and the better-kept secret. October and November bring cooler air, low humidity, empty beaches, and the best fishing of the year. The tourists are gone. The water is still warm. Residents will tell you this is the reason they stay.
Winter is mild and it is the reason retirees come. December through February rarely gets truly cold on the coast. Golf runs year-round. It is the off-season, which means quieter towns, easier restaurant reservations, and the version of the Lowcountry that owners actually get.
Summer is the trough and it is a real one. June through September brings heat, humidity, thunderstorms, and the peak of hurricane season. The tourist population swells on the coast at exactly the moment the weather is least pleasant. August in the Lowcountry is genuinely hard, and pretending otherwise is how people end up reselling.
How the state actually lives.
Hilton Head Island is a mature, deliberately planned barrier island: twelve miles of beach, an enormous golf and tennis infrastructure, strict architectural and tree ordinances that keep it green, and roughly 39,000 year-round residents. It is one of the best-run resort communities in America and it does not look like anywhere in Florida.
Charleston is a genuine historic city with a world-class food scene, and its market extends across Mount Pleasant, Sullivan's Island, Isle of Palms, Daniel Island, and James Island. Kiawah Island is the high-end private option, with the Ocean Course and a level of ecological control that borders on obsessive.
Beaufort and Bluffton are the quieter Lowcountry: tidal, historic, unhurried. Palmetto Bluff, in Bluffton, is a 20,000-acre development on the May River anchored by a Montage, and it operates at a different price level entirely.
Myrtle Beach and the Grand Strand are the opposite proposition: sixty miles of wide beach, high-volume tourism, 17 million annual visitors, and the most affordable coastal entry point in the state by a wide margin.
This is a top-tier American golf state and it is chronically underrated against Florida and Arizona. Harbour Town Golf Links on Hilton Head hosts the RBC Heritage and is one of the most recognizable finishing holes in the sport. Kiawah's Ocean Course has hosted the Ryder Cup and multiple PGA Championships. The Grand Strand carries more than 80 championship courses. Aiken and the Palmetto Golf Club represent the old, quiet, inland tradition.
The trade against Florida is straightforward: South Carolina golf is year-round with a genuine but manageable winter, at a cost of ownership that is materially lower.
The category almost nobody outside the state knows about, and it is genuinely excellent. Lake Keowee in the Upstate is deep, clear, and set against the Blue Ridge foothills, with a serious second-home market anchored by developments like The Cliffs. Lake Jocassee above it is even clearer and largely undeveloped, protected and spectacular. Lake Murray near Columbia is the big recreational lake.
Add the coastal side, which is entirely different in character: the Intracoastal Waterway, the tidal creek system, and the deepwater dock culture that defines Lowcountry property. A dock with deepwater access on a Beaufort County creek is one of the more durable assets in the state.
Modest but real. The Upstate rises into the Blue Ridge foothills, with Greenville as the anchor: a genuinely excellent mid-sized city with a downtown, a river park, a food scene, and mountains twenty minutes away. Table Rock, Caesars Head, and the Jocassee Gorges offer waterfalls, hiking, and cool summer air within an hour.
Nobody relocates to South Carolina for the mountains. But a meaningful number of Lowcountry owners keep a second place in the Upstate for exactly one reason: August.
Aiken is the story here, and it is a genuinely significant one. It is a thoroughbred training and steeplechase town with deep roots, a winter colony history, sandy training tracks, and an equestrian culture that rivals anything in Kentucky or Virginia. Polo, foxhunting, and eventing are living traditions here rather than marketing.
Beyond Aiken, the Midlands hold real quail plantation country and timberland, particularly toward the Georgia line.
Inshore fishing in the Lowcountry creeks for redfish and speckled trout, which is genuinely world-class and criminally under-marketed. Offshore out of Charleston and Hilton Head. The ACE Basin, one of the largest undeveloped estuaries on the East Coast. The Congaree, an old-growth bottomland hardwood forest with the tallest trees east of the Mississippi. Waterfalls in the Jocassee Gorges. And Charleston's food scene, which is not an amenity but a genuine reason people move.

Where the value is moving next.
Lake Keowee and the Upstate
Deep, clear water against the Blue Ridge foothills, an hour from Greenville, and a second-home market that most of the country has never heard of. It offers something almost nothing else in the Southeast does: real lake living with real mountains behind it and a genuine city nearby. The most underrated market in the state.
Ready nowBeaufort
Between Charleston and Hilton Head, and quieter than either. A historic downtown, an antebellum architectural core, the tidal creeks, and a military presence that anchors the economy. It is what Charleston was before Charleston was discovered.
Ready nowAiken
Thoroughbred country in the Midlands: sandy training tracks, steeplechase, polo, and an equestrian culture with real history. Inland means no hurricane storm surge and much lower insurance. For an equestrian buyer, this is one of the best values in America.
Ready nowThe Bluffton and Hardeeville corridor
The fastest-growing stretch of the Lowcountry, with enormous approved development running toward Savannah. This is genuine momentum, not developer marketing, and it will reshape the region. Whether that is opportunity or warning depends entirely on the buyer. Approach with open eyes and a hard look at the traffic study.
