How much does an 8.2% drop in the median price tell you when only 75 homes closed that month? In September 2026, Lake Wylie's median sale price fell to $584,000 from $636,000 a year earlier, according to the Canopy Realtor Association's September 2026 Local Market Update for Lake Wylie. If you're comparing Lake Wylie with Fort Mill, Ballantyne or Lake Norman this fall, that number will show up in every summary you read. The rest of the same report gives a different picture.
| Lake Wylie metric | September 2025 | September 2026 | Year to date through September 2026 |
|---|---|---|---|
| Median sale price | $636,000 | $584,000 | $588,500, up 0.6% |
| Average sale price | $739,448 | $733,262 | $712,112, up 2.9% |
| Closed sales | 92 | 75 | 734, up 2.8% |
| Pending sales | 81 | 60 | 758, up 4.4% |
| Days on market until sale | 64 | 50 | 55, down 8.3% |
| Months' supply | 4.2 | 4.4 | n/a |
September Had Too Few Sales to Carry That Headline
The year-to-date median through September 2026 was $588,500, slightly higher than the $584,995 recorded over the same stretch of 2025. The September average sale price slipped only 0.8%. A median can drop sharply while the average barely moves when the month's small batch of closings leans toward a different price tier than last year's batch did. Canopy's own footnote warns that its percent changes "can sometimes look extreme due to small sample size," and adds that the figures do not account for sale concessions.
The other September numbers describe a market where homes are selling faster. Days on market fell to 50 from 64. Sellers received 95.2% of original list price, compared with 94.4% a year earlier. Inventory rose 6.6% to 338 homes, which works out to 4.4 months of supply.
The comparison inside the county matters too. York County as a whole posted a September 2026 median of $391,995, 3.5 months of supply and 57 days on market, according to Canopy's York County report. Lake Wylie sells at a premium of nearly $200,000 over the county median and has a slightly deeper shelf of listings. One caveat applies to every Lake Wylie figure above: Canopy's Lake Wylie area includes both the North Carolina and South Carolina shores.
So the September median is a weak signal on its own. A better question is what kind of supply will be competing with today's listings over the next few years. In unincorporated York County, most new investment is going into projects that aren't houses.
The Growth Money Went Into a Data Center and a Hospital
Three years ago, the QTS data center in Lake Wylie was pitched as a $1 billion project. The company now projects $8 billion, the Rock Hill Herald reported in September. In the fiscal year that ended in June, unincorporated York County issued 160 non-residential permits valued at $420.2 million. That value was up 123% in a year, even though the number of permits fell 31.3%. County permit center and impact fee administrator Oksana Holbrooks told the Herald that "this large valuation increase is due to the permits from QTS data center building." Some headlines describe this as rising "property values." The figure is non-residential construction permit valuation, which is a different thing from home prices.
The QTS site keeps growing. In December, the company paid $26.1 million for more than 400 acres off Paraham Road, bringing its Lake Wylie holdings to nearly 800 acres, and said it had no plan for that parcel, according to an earlier Herald report. Four buildings were under construction, with the first expected to be ready by 2028 and work on five more expected to start in 2027.
York County has since tightened the rules for future data center projects. A nine-month moratorium on new data centers took effect in July and runs through mid-April. Officials said an extension was likely, though no vote date had been set as of the Herald's October 5 report. The proposed standards would restrict on-site power generation and groundwater use and could lower maximum building height from 80 feet to 60. County staff said the changes would not affect QTS construction already underway, though they could apply to a future expansion.
The second large project is medical. CaroMont Health announced on September 16 that it plans a neighborhood hospital in York County with emergency and inpatient care. It is targeting a 2031 opening, and construction depends on state and local approvals. The Herald reported that CaroMont bought more than 40 acres at SC 557 and Glenn Brandon Road for $6 million.
Recent Rezonings Are Moving Toward Fewer, Larger Lots
Residential approvals in unincorporated York County have moved much more slowly. The Herald's September analysis found that the county approved 557 single-family homes last year. That was the highest total in four years, but it was still 16% below the five-year average. The county also approved 37 townhomes, 68% below the five-year average. It has approved no apartments in four years and only 26 units over the past five. Single-family homes made up 93.8% of residential construction. In the Herald's words, "Small, single-year gains in residential growth mean it's up to businesses to provide the investment growth."
Where the approved lots are located also matters for Lake Wylie buyers. More than 70% of the 268 lots the county planning commission approved last year are in Newport Commons near Rock Hill, a mixed residential and commercial project anchored by a planned Target. The county's FY 2025-26 annual report lists four preliminary plats in all: Gates at Springfield, Sage Mill, Newport Commons and Wedgewood Townhomes.
On Lake Wylie's own back roads, 2026 rezoning requests have mostly asked to lower allowed density. In Case 26-18, a 33.95-acre property on Windmill Lane in Clover moved from RMX-10 zoning to RUD, the county's rural designation, so the owner could build one homestead and a barn instead of a subdivision. The planning commission recommended it 6-0, and County Council gave it third reading on July 13, 2026, according to the Council's July 13 meeting record. The staff report explained the reasoning:
"The current RMX-10 zone allows a housing density that is not appropriate for the area or expected within the FLU."
The same report notes that the property next door was rezoned in January 2026 for similar agricultural uses. Earlier in the year, Case 26-04 asked to rezone an 8.38-acre waterfront parcel on Sand Tar Road in Legacy Point from RMX-10 to RUD. The plan was six single-family lots of roughly one to two acres on private wells and septic, and staff recommended approval. The Case 26-04 staff report put Council readings on the spring 2026 calendar. Both cases point the same way: low-density land staying low-density, or becoming more so.
What This Means for Homes Already on the Market
When new housing is concentrated elsewhere in the county and land near the lake is being rezoned for larger lots, the main competition for any Lake Wylie listing is other existing homes. That changes how you read this fall's numbers.
- Comparable sales will be thin through the end of the year. Pending sales fell to 60 in September 2026 from 81 a year earlier, a 25.9% drop. Fewer pending deals now means fewer closed sales to price against in October and November, and any single sale will move the monthly median more.
- Leverage comes from the shelf of listings. With 4.4 months of supply as of September 2026, buyers have room to negotiate. The shorter 50-day sale time also suggests that well-priced homes aren't sitting for long.
- Asking prices are running ahead of sale prices. The average list price in September 2026 was $775,264, up 8.9% from a year earlier, while the average sale price edged down. That gap is where pricing strategy decides the outcome, for buyers and sellers alike.
- Road work affects everyday travel more than prices. SC 557 is being widened from two lanes to five over about 2.48 miles, with a new bridge over Crowders Creek and two signalized intersections, according to contractor Blythe. SCDOT also scheduled fall 2026 deck repairs on the northbound SC 274 bridge over Big Allison Creek. Traffic would shift to the southbound bridge for about 45 days, with at least one lane kept open in each direction. Drive your actual commute during your showing week.
Questions Buyers Ask About Lake Wylie This Fall
Does the moratorium stop the QTS data center?
No. York County staff said later rule changes would not affect QTS construction already underway. They could apply to a future QTS expansion or to other proposals, as the Herald reported on October 5.
Is the Lake Wylie median a South Carolina figure?
No. Canopy's Lake Wylie area covers both the North Carolina and South Carolina sides of the lake, so a home in York County is being compared with sales on both shores.
When will the SC 557 widening be finished?
The county's August 10, 2026 staff report for a nearby rezoning case describes the widening as in progress through Pennies for Progress, including the realignment of Ridge Road. It does not give a completion date. The same staff report expects the road work to bring a signalized Ridge Road intersection that will change how the area functions.
