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

Custer
Winter roads are a genuine planning factor at this distance, and on acreage you need to know who maintains yours.
Rapid Valley
Highway 44 and Elk Vale are state and county priorities. Interior subdivision streets are county maintained and clear after the arterials do.
Box Elder
I-90 is state maintained and the city clears the newer plats. Box Elder publishes no plow priority map, so ask a neighbor how the street clears after a real storm.
Spearfish
Chinook winds off the hills are a genuine feature of winter in this corridor.

Box Elder
A verify first town for rental plans, with one specific misconception the guide clears up.
Spearfish
The city studied rules in 2023 and 2024 and maintains an official short term rental page. Verify the current ordinance first.

The trade

Housing and patterndiffers

Custer
A county seat at a park entrance, with a replacement Monument Health hospital and acreage starting just past the city limits.
Rapid Valley
The region's largest unincorporated community: suburban streets, high ownership, county government.
Box Elder
A young city building its first downtown at Liberty Plaza on 110 acres, with roughly 800 residential units planned.
Spearfish
A university town with a walkable middle, growing fast enough that new construction has moved to the edges.

What you gaindiffers

Custer
You are inside the Hills with real acreage, Custer State Park at the door, and a new hospital in a town of about 1,900.
Rapid Valley
Rapid City schools and a five mile commute without Rapid City property taxes, plus a walk-in clinic in the neighborhood.
Box Elder
The Ellsworth main gate is in town, 9 minutes from most addresses, on city water and sewer, with the region's newest housing pipeline.
Spearfish
A downtown you can walk across, Black Hills State and Spearfish Canyon out the back door, on city water and sewer.

What you give updiffers

Custer
Rapid City is 50 to 60 minutes and Ellsworth over an hour, grandfathered rental permits expire when a property sells, and outside the city limits there are no county building codes.
Rapid Valley
No city services, a sanitary district bill instead of a city utility bill, and an annexation line that only the parcel record can settle.
Box Elder
Comparable sales run thin inside brand new subdivisions and builder incentives move the effective price without moving the list price. I-90 fills at shift change, and the flight line is close enough that you hear it.
Spearfish
The highest median sold price of the region's higher volume markets at $475,000 across 199 sales, and Rapid City is 53 minutes on the interstate with the Ellsworth gate 68.
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.
