Check three real estate sites for the median home price in Spearfish this week and you will get three different answers. None of them are wrong. Redfin's most recent snapshot puts the median sale price at $553,000 for February 2026. Movoto shows $575,000 for November 2025. Zillow's home value index, which measures something different from either of those, lists the typical Spearfish home at $413,219. Three numbers, one town, all published within the same eight or nine months.
If you are comparing Spearfish to another Black Hills town before you make an offer, that spread matters more than any single figure on the list. It tells you the median itself is not a stable target. It is a blended average of two markets that behave almost nothing alike: brand new construction on the east side of town and older homes closer to Main Street and Black Hills State University. Knowing which one you are actually shopping in, and what is coming behind it, tells you far more than any one portal's headline number.
Three Numbers, Same Town
Here is what each source is actually measuring, and when.
| Source | Period | Figure | What it measures |
|---|---|---|---|
| Redfin | February 2026 | $553,000 median sale price | Actual closed sales that month |
| Movoto | November 2025 | $575,000 median list price | Active and recent listings |
| Zillow | Current | $413,219 typical home value | Estimated value across the entire housing stock |
Redfin's own data shows the volatility even within a single source. Homes sold in an average of 73 days in February 2026, compared with 216 days the year before. That is not a market that suddenly caught fire and then cooled off twice. It is a market where only 10 homes closed that month. When your sample size is that small, one $900,000 custom build or one long-sitting fixer can swing the median and the average days-on-market figure by weeks or tens of thousands of dollars. A single closing has outsized power in a town this size, and every portal is vulnerable to it in a given month.
Zillow's number is structurally different for a separate reason. It is not a median of what sold, it is an estimated value applied across every home in Spearfish, sold or not. That is useful for tracking gradual appreciation, but it will never match a monthly sales median in a low-volume market, and it should not be read as though it will.
What the City's Own Permit Numbers Say
None of the portal numbers tell you what is actually being built next, or at what price point. The City of Spearfish's building permit report does, and it points to something the median price cannot show on its own.
In May 2026, the city issued 39 building permits with a total reported valuation of $10.75 million. In May 2025, it issued 28 permits at $14.74 million. A year before that, in May 2024, it was 23 permits at $5.27 million. Permit counts are climbing every year, which fits a town that grew from 10,494 residents in 2010 to 14,154 in 2025, a 34.8 percent increase. But total dollar valuation did not climb in step with permit count between 2025 and 2026. It fell.
More permits and less total money means the average project is smaller than it was the year before. That is consistent with more additions and alterations, more modest new builds, and fewer of the large custom homes that pushed 2025's total valuation higher. For a buyer watching Spearfish from outside, it means the new construction coming online over the next 12 to 18 months is more likely to be a compact, builder-grade home on an east-side lot than another $800,000 custom build, even while the median price you see quoted today sits well above the statewide figure.
That statewide figure is worth having on hand as a check against Spearfish's own number, not because Spearfish should match it. South Dakota's median sale price was $343,779 in May 2026, up 4.2 percent year over year, with homes taking a median of 54 days to sell. Whichever Spearfish figure you use, it runs well above that state number. The permit trend is one reason the gap may not keep widening at the pace it has: more supply is arriving at a lower entry point than last year's closings suggest.
Why Even Renters Are Feeling the Squeeze
The clearest evidence that Spearfish's supply problem runs deeper than a single median can show came on June 5, 2026, when developer Buxton Enterprises broke ground on Peak View II, a 32-unit affordable apartment complex on 3.5 acres off Paramount Drive in eastern Spearfish. Lloyd Companies of Sioux Falls is building it. The $9.3 million project is funded through $7.4 million in federal tax credits, $1 million from the HOME Program, and $600,000 from the Housing Trust Fund, all administered through the South Dakota Housing Development Authority, with additional support from a $30 million congressional earmark tied to the Ellsworth Air Force Base expansion. Tenants earning between 30 and 60 percent of the area's median income of $96,100 are expected to pay between $600 and $1,300 a month starting in summer 2027, well below Spearfish's market-rate rents.
What stood out from the groundbreaking was not the funding structure. It was who said what.
"With high land costs, building costs, engineering costs and soft costs, it's pretty hard to make a project work without some type of subsidy."
That is Jeremy Hoven, president of the Black Hills Community Bank branch in Spearfish, describing why even a subsidized, income-qualified apartment complex needed a rare federal earmark to pencil out. If a local bank president is on record saying subsidy is close to necessary for affordable rental housing to get built, that tells you something about the cost pressure facing unsubsidized, entry-level home construction too. The same land, labor, and engineering costs apply whether the end product is a rental unit or a starter home.
That cost pressure is landing on a town that is growing fast. A population increase of nearly 35 percent in fifteen years is a lot of new demand for a housing stock that, per the city's own permit data, is adding smaller and less expensive units than it was building just a year ago. Those two forces, rising demand and moderating new-construction costs, are pulling against each other in the same market at the same time.
What This Means If You're Comparing Spearfish to Somewhere Else
Before anchoring an offer to a single median price, it helps to ask two questions that the portals do not answer for you.
- Are you shopping new construction or resale? The 2026 permit data suggests new construction is trending toward smaller, less expensive projects than 2025's closings. If you are looking at a builder's spec home, ask how its price compares to the city's current-year permit valuations, not last year's closed sales.
- What is the property's actual days-on-market history, not the town-wide average? A single closing can move Spearfish's monthly median by tens of thousands of dollars in either direction. An individual listing's own time on market, and whether a price reduction has already happened, tells you more about your negotiating room than the headline number ever will.
For resale specifically, expect more room to negotiate around the results of a systems inspection, particularly on older homes near Main Street or Black Hills State University where mechanicals and layouts have not been updated to current standards. For new construction, expect pricing that tracks the builder's other lots and the current permit trend more closely than any blended citywide median.
Frequently Asked Questions
Why do Zillow, Redfin, and Movoto show different numbers for the same town? They are measuring different things. Redfin and Movoto report medians from actual sales or active listings in specific months. Zillow's index estimates value across the entire housing stock, sold or not. In a low-volume market like Spearfish, monthly sales medians can also swing hard simply because so few homes close in a given month.
Is Spearfish a buyer's market or a seller's market right now? It depends heavily on which segment you're in. Statewide, South Dakota's May 2026 data shows a fairly balanced market, with homes selling in a median of 54 days and 13.1 percent selling above list price. Spearfish runs above the state median on price across every source, but its low sales volume means conditions can look very different from one closing to the next.
Should I wait for new construction prices to come down? The city's permit data shows average project value per permit fell between May 2025 and May 2026, which suggests more entry-level new construction is coming. But the cost pressures described around the Peak View II project, land, labor, and engineering costs, make a significant across-the-board price drop unlikely in the near term.
The median price you see quoted for Spearfish is a real number, but it is describing two different markets at once, and neither the new-construction segment nor the resale segment moves the way a single blended figure suggests. Reading the city's own permit data alongside the sales numbers gives a truer picture of what your budget is actually up against.
