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.

The trade
Housing and patterndiffers	An 1891 French-Canadian railroad townsite that is now a cattle auction crossroads and an acreage corridor.	New streets and builder inventory, with Highlands at Norman Ranch adding over 100 first phase homesites across more than 300 acres.	An 1883 mining camp turned tourism town at the gateway to Mount Rushmore, 240 residents and millions of visitors.	A county seat at a park entrance, with a replacement Monument Health hospital and acreage starting just past the city limits.
What you gaindiffers	The cheapest ground in the northern Hills that still puts you eleven miles from a hospital and sixteen from three towns.	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.	Nightly rental demand runs about as high as anywhere in the Black Hills, if the rules and the covenants check out for the specific property.	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.
What you give updiffers	A three-way school district split you have to verify per parcel, and no services of any kind in town.	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.	A seasonal town with no school, no grocery and no clinic, and a housing stock where half the doors are dark in winter.	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.

Recreationdiffers

St. Onge: Creek bottoms, hay ground and hunting country, with Spearfish Canyon and the northern Hills half an hour away.
Summerset: Leisure Lane, Steamboat and Castlewood parks are the everyday recreation. Leisure Lane is the big one, with playgrounds, basketball, picnic shelters, open grass and the community garden.
Keystone: Mount Rushmore is past the town boundary, the 1880 Train runs from the Winter Street depot, and Custer State Park and the Norbeck Scenic Byway are close.
Custer: Custer State Park at the door, including Sylvan Lake, the Needles Highway, the wildlife loop and the September buffalo roundup.

The trade

Housing and patterndiffers

St. Onge: An 1891 French-Canadian railroad townsite that is now a cattle auction crossroads and an acreage corridor.
Summerset: New streets and builder inventory, with Highlands at Norman Ranch adding over 100 first phase homesites across more than 300 acres.
Keystone: An 1883 mining camp turned tourism town at the gateway to Mount Rushmore, 240 residents and millions of visitors.
Custer: A county seat at a park entrance, with a replacement Monument Health hospital and acreage starting just past the city limits.

What you gaindiffers

St. Onge: The cheapest ground in the northern Hills that still puts you eleven miles from a hospital and sixteen from three towns.
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.
Keystone: Nightly rental demand runs about as high as anywhere in the Black Hills, if the rules and the covenants check out for the specific property.
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.

What you give updiffers

St. Onge: A three-way school district split you have to verify per parcel, and no services of any kind in town.
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.
Keystone: A seasonal town with no school, no grocery and no clinic, and a housing stock where half the doors are dark in winter.
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.

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.
