Compare Black Hills Communities

25 towns and unincorporated communities. Pick two to four and the full table appears underneath. Commutes are driving times to the Ellsworth main gate and downtown Rapid City. Median sold prices, where we have them, come from the MLS over the trailing twelve months with the source, window and sale count printed under each figure. Typical price bands are practical search ranges, not medians, and are labelled separately.

Price filters only consider communities with a published trailing twelve month median, so towns without one do not appear in a price filter.

Rapid City and the Ellsworth corridor

Everything within about twenty five minutes of downtown Rapid City or the Ellsworth main gate, where most of the newer inventory, the shortest commutes and the jurisdiction questions about city versus county service are.

Winter drivingdiffers

Summerset
The commute is I-90, so winter driving here is interstate driving rather than a two lane canyon road.
Edgemont
Cold semi-arid country with a recorded low of 40 below. US 18 is the lifeline and it is a long way to anywhere in a storm.
Buffalo Gap
Highway 79 is state maintained and is the connection to Hot Springs and Rapid City. Off it, this is open prairie with blowing snow.
St. Onge
Highway 34 is state maintained and connects three directions. County and private roads off it are a different conversation.

Housing and lots

Typical pricediffers

Summerset
Builder inventory sets the level here, and the MLS publishes no Summerset median on its own.
Edgemont
About $155,000 average sold, 13 sales over 24 monthsAverage sold $155,285. Black Hills MLS, single family, 24 months through August 2026, as of August 2026. 13 closed sales.
Buffalo Gap
One single family sale shows in the Black Hills MLS over 24 months, at $80,000. One closing is a sample of one rather than a price level, so read it that way.
St. Onge
No figure published. St. Onge is Mount Rushmore Area MLS territory and the current feed covers only the Black Hills MLS, so a zero here would be a gap in the data rather than a fact about the market.

Housing agediffers

Summerset
Mostly 2000s to present
Edgemont
An 1890 railroad town, so mostly older stock, with about a quarter of units vacant at the 2020 count.
Buffalo Gap
An 1885 to 1939 historic core with an aging housing stock and about a fifth of units vacant.
St. Onge
An 1891 townsite with genuinely old buildings, surrounded by ranch and acreage property of every era.

Edgemont
City water and sewer inside the limits
Buffalo Gap
Mixed, municipal service in town with well and septic outside it

Waterdiffers

Summerset
Black Hawk Water User District, or Diamond D Water in Sun Valley

Buffalo Gap
Town of Buffalo Gap municipal water from a single well, serving about 93 connections. Rural parcels are on private wells.
St. Onge
The Saint Onge Sewer and Water Company serves about 78 connections around the townsite, with a clean compliance record. Parcels outside that system are on private wells. There is no rural water district covering this area.

Sewerdiffers

Summerset
City of Summerset
Edgemont
City sewer inside the limits, with private septic on rural parcels.
Buffalo Gap
Not documented in the public record. There is no municipal wastewater project or discharge permit on file that I could find. Confirm with the town finance officer before assuming either town sewer or septic.
St. Onge
The water company's name implies sewer service, but I have not been able to verify from the public record which parcels it reaches. Assume private septic outside the townsite and confirm the rest before closing.

Short term rentalsdiffers

Summerset
The thinnest rules on this list, which means a rental plan has to be pinned down for the specific address.
Edgemont
Edgemont is not a tourism town. Short-term rental demand here is work crews, hunting season and Rally traffic passing through, not visitors staying to see something.
Buffalo Gap
This is hunting and grassland country rather than a tourism corridor. Demand is seasonal and specific.
St. Onge
Unincorporated Lawrence County, so no municipal ordinance applies. Note that unincorporated Lawrence County declined to require a vacation home rental permit, so there is no county permit to obtain either.

The trade

Housing and patterndiffers

Summerset
New streets and builder inventory, with Highlands at Norman Ranch adding over 100 first phase homesites across more than 300 acres.
Edgemont
A working BNSF crew-change town founded in 1890, at the far southern edge of the Hills below the Elk Mountains.
Buffalo Gap
A nearly intact turn-of-the-century western streetscape on the National Register, mostly quiet, at the gate to the grassland.
St. Onge
An 1891 French-Canadian railroad townsite that is now a cattle auction crossroads and an acreage corridor.

What you gaindiffers

Summerset
Newer houses on city sewer with Hills views at a price central Rapid City does not offer, and Highlands at Norman Ranch is still selling first phase homesites.
Edgemont
More town per dollar than anywhere else in the region, with its own school district and city utilities.
Buffalo Gap
Eighteen minutes from the hospital in Hot Springs, with 600,000 acres of grassland out the door and one MLS closing in two years to price from.
St. Onge
The cheapest ground in the northern Hills that still puts you eleven miles from a hospital and sixteen from three towns.

What you give updiffers

Summerset
You are fifteen minutes out from most of Rapid City's services and you drive I-90 to get to them in the winter. The city is also split between Meade 46-1 and Rapid City Area Schools 51-4, so the district follows the address.
Edgemont
A hundred miles from Rapid City, 35 from a hospital, with two unresolved questions hanging over the local economy.
Buffalo Gap
No school, no store and no services in town, an aging water system with an open compliance item, and an undocumented sewer situation.
St. Onge
A three-way school district split you have to verify per parcel, and no services of any kind in town.
Where this comes from

Commute figures are driving times off peak, from the community guide each card links to. Median sold prices come from the MLS, and each figure carries its own source, window and closing count, because Sturgis, Spearfish and the northern hills report through a different MLS than Rapid City. Under five closings there is no median, and the price row says so. Five to nine closings carries a small sample note. School districts follow the official boundary for the address, and the district office is the only place to confirm an assignment. Short term rental lines are summaries. Read the guide and the current ordinance before you count on rental income.

The filters use these definitions: under $400k is the MLS sold figure for the town, a median where one is published and otherwise the average sold, comes in under $400,000; close to ellsworth is 25 minutes or less to the Ellsworth main gate; close to rapid city is 20 minutes or less to downtown Rapid City; short commute is 15 minutes or less to either downtown Rapid City or the Ellsworth gate; new construction available is the guide establishes active or limited new construction; acreage available is acreage is common or present in the guide; city water and sewer is city water and sewer across the community; smaller market is fewer than 100 closed single family sales in the trailing twelve months; more rural is acreage is common, or water and sewer are not municipal throughout; established housing is the guide classifies the housing stock as established, meaning largely pre 2000; newer housing is the guide classifies a meaningful share of the housing stock as 2000s or later.

Every row here is a townwide summary and a single parcel can read differently. Buyer due diligence should include verifying water and sewer service, school assignment, recorded covenants and HOA obligations, rental rules, legal access, insurance availability and which jurisdiction inspects and permits the work, for the exact address. Confirm with the city or county, the utility or district, the school district office, the title company and your insurer as applicable.
