A family with PCS orders to Shaw Air Force Base does the sensible thing before they ever call an agent. They open a browser and search "Sumter SC home prices." Three tabs later, they have three different numbers for the same city, and none of them agree by less than $50,000.
That is not a glitch. It is the most useful thing you can learn about this market before you write an offer.
Three numbers, one city
Here is what shows up if you run that search today.
| Source | What it actually measures | Figure | Time window |
|---|---|---|---|
| Zillow's home value index | A smoothed "typical value" across the full housing stock, old and new | $175,127 | year ending June 2026 |
| Redfin closed sales | The median price of homes that actually closed that month | $271,000 | March 2026 |
| Realtytrac | Median list price of active listings | $254,900 | current listings |
A $96,000 gap between the low and high figures is not rounding error. It is three different questions getting three different honest answers. Zillow is telling you what a typical Sumter home, including the 1970s brick ranch on a half-acre lot that's never been remodeled, is worth on paper. Redfin is telling you what buyers actually paid for the specific 68 homes that closed in March. Realtytrac is telling you what sellers are asking right now, before any negotiation happens.
None of these are wrong. They are measuring different slices of the same small market, and in a market this size, the slices don't have to agree.
Why a thin market swings this hard
Sixty-eight closed sales in a month sounds like plenty until you compare it to a metro market moving thousands of homes. In a small sample, a handful of new-construction closings can drag the median a long way. Sumter has been adding exactly that kind of inventory. Subdivisions like Jackson Preserve off Camden Highway, Heritage Bay near downtown, Canopy of Oaks off Highway 378, and Crystal Downs near Highway 521 have been delivering new single-family homes from builders including Great Southern Homes and McGuinn Homes, many priced well above the decades-old stock that still makes up most of the city's housing.
Meanwhile, the older corridors near the base, places like Lakewood, Millwood, and the Alice Drive area, keep trading at prices close to what Zillow's broad index reflects. Two homes ten minutes apart can be, in effect, two different markets sitting inside the same zip code.
So when Redfin's March 2026 data shows the median sale price up 23.1 percent year over year, that is not necessarily every home in Sumter getting more expensive at that pace. It is at least partly a mix shift: a bigger share of that month's closings were new construction, which pulls the median toward the top of the market even if the older stock barely moved.
This matters enormously if you're translating a housing allowance into a number you can actually spend.
The BAH math this affects
Basic Allowance for Housing for the Sumter/Shaw AFB military housing area increased 4.9 percent from 2025 to 2026, one of the larger regional increases in the Air Force. That's real, and it's meant to track rising costs. But a family running the math on whether to rent or buy needs to know which Sumter they're budgeting against.
If you anchor your expectations to the $175,127 Zillow figure, a BAH-backed VA loan looks like it comfortably outpaces most of what's on the market. If you anchor to Redfin's $271,000, the math looks tighter, and you might assume you need to compromise on square footage or commute distance to make it work. Both instincts are reasonable. Neither is complete without knowing which segment of the market you're actually shopping in.
Renting has its own version of this confusion. Three-bedroom rentals in Sumter typically run $900 to $1,300 a month, with reported medians closer to $920. That's a wide enough band that "average rent in Sumter" tells you almost nothing about what you'll pay for a specific house near a specific gate.
The practical fix is simple: ask whatever agent you're working with for the median closed price in the specific subdivision or corridor you're actually considering, not the city-wide blended number. A city-wide median is a weather report. A subdivision-level number is what you'll actually pay.
The part the price headlines don't mention
Here's the detail that surprised me most in the data: while Redfin's reported median price jumped double digits year over year, the average time on market in Sumter also grew, from 45 days a year ago to 63 days in the most recent reporting. Redfin's own competitiveness score puts Sumter at 56 out of 100, "somewhat competitive," not a bidding-war market.
That combination, prices climbing while homes take longer to sell, tells you the increase is concentrated in specific new inventory rather than reflecting broad-based demand outracing supply across the whole city. A buyer who reads "prices up 23 percent" and assumes they need to waive inspections and bid over asking on every house is working from an incomplete picture. In most of the existing housing stock, you likely still have room to negotiate and time to think.
More supply is coming, but it isn't here yet
The city has already responded to the pressure Shaw AFB's continued presence puts on local housing. Sumter's planning committee recently approved new subdivision and apartment development at three sites, Carter Road, Loring Mill Road, and Patriot Parkway, specifically to address west-side housing demand.
"It's to build the downtown up, build a mass where infrastructure is, has been a primary focus in ways to have more affordable housing," Sumter Planning Manager Jeff Derwort said of the approvals. County Councilman Carl Washington tied the timing directly to the base, noting the region's growth pressure is driven in large part by Shaw's ongoing expansion, with more projects already discussed for the pipeline.
That's good news for anyone PCSing in over the next few years, but it's forward-looking. The apartments and lots approved on Carter Road hadn't set a completion date as of the most recent reporting. If you have orders now, you're shopping in today's inventory, not tomorrow's.
What this means for the financing side
Rate environment matters here too, and it's moved recently. Freddie Mac's 30-year fixed conventional rate averaged 6.71 percent as of September 3, 2026. VA-specific rates have been running meaningfully below that, with national averages closer to 6.36 percent in mid-August, reflecting the typical 0.25 to 0.50 percentage point discount VA loans carry over conventional financing. That gap is worth confirming with a VA-specialist lender before you assume your BAH won't stretch as far as it should.
A short list before you start looking
- Ask for the median closed price in the specific subdivision or corridor you're considering, not a city-wide average.
- Compare that number to your actual BAH, not a national headline about rate cuts or increases.
- Check days on market for that specific area. Sixty-plus days citywide means most sellers aren't fielding multiple offers.
- If a listing sits inside one of the newer subdivisions like Jackson Preserve, Heritage Bay, or Crystal Downs, expect pricing closer to Redfin's higher figure. If it's in an older corridor like Lakewood or Millwood, expect something closer to the broader index.
- Get a same-day rate quote from a VA-specialist lender rather than relying on a headline conventional rate.
The bottom line
Sumter isn't lying to you. It's a small market in the middle of a real supply shift, with new construction and decades-old housing stock closing in the same monthly data pull. The median you see depends entirely on which slice of that market got sampled that month. For a family trying to turn a BAH number into an actual offer, the fix isn't finding the "correct" website. It's knowing enough about the local mix to read any number for what it actually represents.
