Edgefield County Is Four Different Housing Markets
A single county-wide median hides four submarkets with almost nothing in common except a shared county line.
| Submarket | Typical price range | Typical property | Who buys here |
|---|---|---|---|
| Historic Edgefield town | $85,000 to $220,000 | Small in-town lots, homes built 1920s to 1960s | First-time buyers, downsizers, small-scale rental investors |
| North Augusta side (Tavern Hill, Mount Vintage) | $390,000 to $610,000 | New construction, 2,500 to 3,800 sq ft subdivisions | CSRA commuters, move-up buyers |
| Rural acreage (Trenton/Johnston/Modoc corridors) | $107,000 to $270,000 for 15 to 38 acre tracts | Undeveloped or lightly developed land | Investors, hobby farmers, privacy buyers |
| Trenton/Johnston in-town | Lower price points; highest effective tax rate in the county at 0.59% in Johnston | Small town lots | Budget buyers, long-time residents |
A buyer comparing Edgefield County against Aiken or Augusta on a single average is comparing the wrong number to the wrong market. The North Augusta corridor competes directly with new subdivisions across the county line in Aiken County; the rural corridor competes with neither.
One example of what new construction near North Augusta actually means in practice: Stanley Martin Homes lists a 2,571 sq ft “Pinewood” plan at Tavern Hill for $389,900, and a 3,846 sq ft “Tanglewood” at Mount Vintage for $609,900. Neither is close to the seven-figure new-construction price sometimes assumed for this corridor.
Is Edgefield County affordable compared to Augusta or Aiken?For the North Augusta-side new-construction submarket, no: $390,000 to $610,000 is priced in line with comparable Aiken County new construction. For the historic in-town and rural-acreage submarkets, yes: both sit well under the county-wide median.
What the Recent Sales Numbers Show
Three Redfin pages, pulled the same week, give three different numbers for what looks like the same statistic. The single-month figure for May 2026 puts the median sale price at $311,266, up 6.6% year over year. The three-month trailing figure for the period ending April 2026 puts it at $330K, down 12.8% year over year. The current median list price across 23 active listings is $340K.
These aren’t contradictory so much as differently windowed: a county with roughly 16 to 32 home sales in a typical month has a small enough sample that a single month’s closings can swing the median in either direction, and a rolling three-month average will disagree with any one month inside it. Days on market has moved from about 180 days a year ago to roughly 95 to 116 days now.
Why do list price and sale price look different here?The $340K figure is what sellers are currently asking; the $311,266 figure is what buyers closed at in May. A gap between the two is normal and doesn’t by itself imply overpricing, but it’s worth confirming which number a specific comparison is using.
Property Tax: What the 4% and 6% Assessment Ratios Cost
South Carolina taxes owner-occupied primary residences at a 4% assessment ratio, and rentals and second homes at 6%. In Edgefield County’s unincorporated areas, the 2025 total millage is 0.1137 in county base plus 0.0110 in county fire protection. Owner-occupied homes also owe the 0.0370 school bond millage but are exempt from the 0.2133 school operating millage; non-owner-occupied properties owe both, for a total millage of about 0.3750 against 0.1617 for an owner-occupant.
| Home value | Owner-occupied (4%) annual tax | Non-owner-occupied (6%) annual tax | Difference |
|---|---|---|---|
| $200,000 | $1,294 | $4,500 | $3,206 |
| $300,000 | $1,940 | $6,750 | $4,810 |
| $400,000 | $2,587 | $9,000 | $6,413 |
The gap widens with price because both the higher assessment ratio and the added school-operating millage apply to the larger base. An investor modeling a $300,000 rental on the owner-occupant number would underestimate the annual carrying cost by nearly $4,810. The 4% rate isn’t automatic: it requires a legal-residence application filed with the county assessor after closing.
Do investors pay a different property tax rate than owner-occupants in South Carolina?Yes. Non-owner-occupied residential property, including rentals and second homes, is assessed at 6% instead of 4%, and it also owes the school operating millage that owner-occupied homes are exempt from.
Climate Risk and the Insurance Question
| Risk factor | Share of properties affected | What it means in practice |
|---|---|---|
| Flood | 8% (1,317 properties), minor county-wide risk | Concentrated near specific waterways; check FEMA zone status before waiving flood coverage on a given parcel |
| Wildfire | 96% carry some exposure, moderate county-wide risk | Rural, wooded acreage lots are more likely to face defensible-space or vegetation-clearance conditions from insurers |
| Extreme heat | 7 days over 107°F projected this year, rising toward 16 days within 30 years | A longer-term cooling-load and HVAC-sizing consideration more than an immediate cost |
These figures come from Redfin’s First Street-sourced data. None of it ties directly to a premium quote at the county level. A buyer on a wooded acreage lot should get a specific wildfire quote from an insurer rather than assume the county-wide moderate rating applies evenly to their parcel.
Does the flood or wildfire risk here affect insurance costs?It can, particularly for wildfire exposure on rural acreage, but the size of that effect depends on the specific parcel and insurer, not on the county-wide percentage alone.
How Small the County’s Tax Base Really Is
One county mil in Edgefield County is worth $116,000 in total revenue. One mil in neighboring Aiken County is worth $980,000. A county this small runs on a narrow base.
Schools Vary More Than the Names Suggest
| School | Level | 2025 SC report card rating | Note |
|---|---|---|---|
| Merriwether Middle | Middle | Excellent, 2nd consecutive year | Highest rating available in the current system |
| Johnston-Edgefield-Trenton Middle | Middle | Good, up from Average (+7 points) | |
| Strom Thurmond High | High | Average (+4 points); graduation rate up from 84.2% to 88.6% | Only high school serving the district |
| Douglas Elementary | Elementary | Average (+13 points) | |
| Merriwether Elementary | Elementary | Average (−3 points) | Rated Good specifically in Academic Achievement |
| Johnston Elementary | Elementary | Below Average | Rated Good specifically in School Climate |
A buyer’s zoned elementary school swings from Below Average to Average depending on which of four in-district elementary schools a specific address feeds into, according to the 2025 state report card results, even though every address shares the same district label.
Who This Fits, and Who It Doesn’t
Edgefield County works for:
- Retirees and remote workers buying in-town in historic Edgefield, where price and property tax are both low and daily commuting isn’t a factor.
- CSRA commuters comparing Tavern Hill or Mount Vintage new construction against similarly priced Aiken County subdivisions.
- Rural-acreage buyers and small investors comfortable with land in the $107,000 to $270,000 range and the 6% rate if the property won’t be owner-occupied.
It does not fit:
- Anyone needing walkable, in-town new construction. Nearly all active new construction found in this research sits on the North Augusta side, not downtown.
- Anyone assuming one property-tax bill applies county-wide. The 4%/6% gap alone runs into the thousands annually, before submarket differences in effective rate are added.
- Anyone assuming the school district name means uniform quality. The zoned elementary school alone spans Below Average to Average across four in-district options.
