Fort Mill Added 2,700 People Last Year. I-77 Didn't Budge

You're sitting on I-77 southbound, brake lights stretching toward the state line. The drive from Uptown Charlotte to Fort Mill used to be 25 minutes. Today it's 48. A pickup weaves around you near the Carowinds exit, and your podcast is the only thing keeping you sane. You've done this drive a thousand times. It's getting worse, and you know exactly why: everybody wants to live where you live.

Fort Mill added roughly 2,700 residents in its most recent single-year Census estimate, an 8.8% jump that ranked it among the fastest-growing cities in the country for its size, per U.S. Census Bureau data. The 2020 census counted 24,521 residents; the Bureau's latest estimate puts the town at 30,775 as of July 2024. But I-77 south of Charlotte? Not one new through lane. Same merge near Gold Hill Road. Same bottleneck at Exit 90. The road serving Fort Mill commuters hasn't been widened in years.

Here's the part most Fort Mill homeowners don't realize: that traffic problem is actually working in your favor. Worse commute, higher home value. It sounds backwards, but the math holds up.

TL;DR: Fort Mill's most recent single-year Census estimate showed roughly 8.8% growth, and the town reached about 30,775 residents in the Census Bureau's 2024 estimate, but I-77 south of Charlotte hasn't expanded. The median home price is now $530,000 (Redfin), up 2.6% year over year. Growth plus limited infrastructure means rising values for existing homeowners.

How Fast Is Fort Mill Actually Growing?

Fort Mill added roughly 2,700 residents in its most recent single-year Census estimate, an 8.8% jump that ranked it 13th among the fastest-growing U.S. cities over 20,000 people (2022 to 2023). Per U.S. Census Bureau figures, the 2020 census counted 24,521 residents, and the Bureau's latest estimate puts the town at 30,775 as of July 2024.

The pace has been remarkable for a town this size, even though the Census Bureau's 2024 estimate reflected a modest downward revision from its 2023 figure. Fort Mill also ranked 7th among the fastest-growing U.S. suburbs from 2018 to 2023, trailing nationally only a handful of Sun Belt suburbs in Texas and Florida. The drivers aren't complicated: Fort Mill's public schools rank among the best in South Carolina, property taxes run lower than the North Carolina side of the border, and Charlotte's job market sits 20 miles up the highway. Over the last five years, Fort Mill has averaged more than 1,500 new residents per year, part of a broader metro area pushing toward 1 million (Axios Charlotte). The result is a town where new subdivisions are going up along Dobys Bridge Road and Highway 160 as fast as builders can pour foundations. And the pace isn't slowing.

Why I-77 Isn't Getting Fixed for Fort Mill

The I-77 Express Lanes run north of Charlotte toward Mooresville, covering 26 miles. Fort Mill commuters heading south don't get a single toll lane, express bypass, or funded expansion, despite traffic volumes growing 15% since 2020.

The toll system that opened north of Charlotte covers about 26 miles of corridor. That toll system helps Lake Norman commuters heading to SouthPark or Uptown. But it doesn't do anything for you if you live in Fort Mill. South of Charlotte, I-77 stays as it has been for years: general-purpose lanes with no toll option, no express bypass, and no funded expansion on the books. The stretch from Exit 90 near Carowinds to the I-485 interchange carries traffic volumes that have grown 15% since 2020, while the through lanes serving Fort Mill commuters haven't been widened to match. During morning rush, the drive from Fort Mill to Uptown stretches to 40 to 60 minutes depending on the day. Wrecks near the Gold Hill Road merge or the I-485 split can add another 20 minutes.

The toll lanes help Mooresville commuters. Fort Mill commuters got nothing new and about 2,700 new neighbors.

For a homeowner thinking about selling, this matters: the commute is one of the top complaints in Fort Mill community forums. New buyers weigh it heavily. But here's what they keep deciding, over and over: the schools, the taxes, and the price point still beat the alternative. A comparable home in Ballantyne (28277) runs $580,000 to $650,000, while Fort Mill's median sits well below that. That's $55,000 to $125,000 less for a better school district. The commute is the cost of the deal, and buyers keep paying it.

Why Worse Traffic Is Actually Good for Your Home Value

Fort Mill's median home price reached about $530,000 over the three months ending May 2026, up 2.6% year over year (Redfin). That is roughly in line with Charlotte proper, which also appreciated in the low single digits over the same period. The reason is a supply squeeze created by the same growth that makes your commute longer.

Here's how it works. Demand keeps climbing (about 2,700 new residents in the latest annual Census estimate), but the number of homes available hasn't kept pace. Infrastructure bottlenecks on I-77 and local roads have pushed the town to slow down new development approvals, making it harder for builders to add supply. Fewer homes coming onto the market means the ones already there hold more value. Picture this: say you bought your home in Fort Mill's Regent Park neighborhood near Highway 160 for $420,000 in 2022. At today's more moderate pace of appreciation, that home is now worth roughly $455,000 to $475,000. The traffic got worse. Your home also got $35,000 to $55,000 more valuable. Both things happened for the same reason.

The traffic isn't a flaw in Fort Mill's market. It's a constraint that keeps your home scarce and your value climbing.

The numbers tell a clear story. Fort Mill homes cost less and carry lower property taxes than the closest comparable neighborhood on the North Carolina side. You won't find that combination anywhere else this close to Charlotte. The trade-off is about 15 to 20 extra minutes in traffic. That's the deal buyers keep taking, and it's why your home value keeps going up. For homeowners thinking about a move, the question isn't whether your home has gained value. It almost certainly has. The question is whether right now, with prices near a peak and demand still strong, is the right time to time your sale for the best return.

What About the Commute Costs You're Paying?

A Fort Mill homeowner commuting to Uptown Charlotte five days a week spends roughly $5,000 a year on gas and vehicle wear, covering about 40 miles round trip daily. But SC's lower property tax rate saves $2,000 to $3,000 a year versus Mecklenburg County, and Fort Mill's top-rated schools can eliminate $12,000+ in private-school tuition.

The commute has a price tag beyond frustration. A Fort Mill homeowner driving to Uptown Charlotte five days a week covers about 40 miles round trip. At the IRS standard mileage rate, that's roughly $14,400 a year in vehicle costs. Even if you just count gas and basic wear, you're looking at $4,000 to $6,000 a year depending on your car. But here's the flip side: SC's lower property tax rate saves Fort Mill homeowners $2,000 to $3,000 a year compared to Mecklenburg County on a similarly priced home. The schools eliminate the private-school cost that some Charlotte parents face, which can run $12,000 to $25,000 a year. That's money you aren't spending. So the commute costs real money every month, but it's offset by savings most people don't calculate until they sit down and run the full picture. The homeowners we talk to in Fort Mill generally feel they're ahead on the total math, even with the drive. The ones who decide to sell tend to have a life change pushing the timeline (a job across town, a parent who needs help, a second home in play) rather than a pure cost calculation.

Is Fort Mill a Good Place to Sell Right Now?

Yes, if your timing lines up. Fort Mill homes sit about 63 days before selling (Redfin, July 2026), with a sale-to-list ratio near 98% and a competitiveness score of 56 out of 100. That's a balanced market with strong demand behind it.

The 63-day average is up from 58 days a year ago, according to Redfin's data, which tells you the market has cooled slightly from its red-hot pace but remains solid. Homes are still selling close to asking price (sale-to-list ratio near 98%), and inventory is tight. Fort Mill's competitiveness score is 56 out of 100, meaning it's a balanced market that doesn't dramatically favor buyers or sellers. If you've been in your home for three or more years, you're likely sitting on significant equity. A Fort Mill homeowner who bought in 2022 at $420,000 is looking at a current value near $455,000 to $475,000. That's $35,000 to $55,000 in equity built in roughly four years. Whether selling makes sense depends on your next step. If you're relocating, downsizing, or picking up a property in a lower-cost area, this is a strong position to sell from. If you're staying in the Charlotte metro and need to buy again at these prices, the math gets tighter. Some Fort Mill homeowners also explore what a full breakdown of selling costs looks like before making the call. Check your specific numbers first. Your Fort Mill selling options guide breaks down the paths available to you.

If you bought in Fort Mill three years ago, you're likely sitting on $40,000 or more in equity you didn't have to lift a finger to earn.

The RobinOffer Take

Fort Mill's growth story isn't slowing down. The schools, the tax savings, and the proximity to Charlotte jobs create a durable combination that keeps pulling people across the state line. The infrastructure gap on I-77 is real and frustrating, but it's also creating a supply constraint that pushes existing home values higher. That makes right now a strong window for Fort Mill homeowners who are thinking about selling, especially if a life event is moving up the timeline. The data shows Fort Mill home values holding up in step with the broader Charlotte metro. But the current pace also means you'll want to price correctly from day one. Overpriced homes sit, even in Fort Mill. For homeowners who want speed and certainty, a cash offer or traditional listing comparison is worth running before you commit to either path.

3 Things Fort Mill Homeowners Should Do This Month

1. Check your current home value. The appreciation rate we flagged above means your number from last year is outdated. Get a fresh estimate. It takes two minutes and costs nothing. Use a tool like ListRobin's home value estimator to see where you stand.
2. Look up your property tax assessment. York County reassesses on a schedule. If your assessed value hasn't kept pace with market value, you may be paying less than expected, which is good. If it jumped recently, you've got the right to appeal. York County Assessor's office handles appeals.
3. Map your commute alternatives. If I-77 is wearing you down, check whether Highway 160 to I-485 or the back route through Tega Cay saves time. Many Fort Mill commuters have cut 10 to 15 minutes by shifting to less obvious routes during peak hours. It's worth testing before you decide whether the commute is a dealbreaker.
