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.

0 of 25 communities

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

Winter drivingdiffers

Rapid Valley
Highway 44 and Elk Vale are state and county priorities. Interior subdivision streets are county maintained and clear after the arterials do.
Custer
Winter roads are a genuine planning factor at this distance, and on acreage you need to know who maintains yours.
Summerset
The commute is I-90, so winter driving here is interstate driving rather than a two lane canyon road.
Keystone
Black Hills elevation on canyon roads, and a town that empties out for the season. Iron Mountain Road and the scenic routes are not winter commuting roads.

Waterdiffers

Short term rentalsdiffers

Rapid Valley
Unincorporated Pennington County has no city short-term rental ordinance to comply with, which is not the same as no rules. County zoning and any subdivision covenants still govern, and state licensing applies.
Custer
Grandfathered permits are non transferable and expire when the property sells, and the rules flip at the city line.
Summerset
The thinnest rules on this list, which means a rental plan has to be pinned down for the specific address.
Keystone
A 2 percent municipal lodging tax applies to transient stays. Whether a separate short term rental ordinance exists is not clear from the public record, so confirm with the town in writing.

The trade

Housing and patterndiffers

Rapid Valley
The region's largest unincorporated community: suburban streets, high ownership, county government.
Custer
A county seat at a park entrance, with a replacement Monument Health hospital and acreage starting just past the city limits.
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.

What you gaindiffers

Rapid Valley
Rapid City schools and a five mile commute without Rapid City property taxes, plus a walk-in clinic in the neighborhood.
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.
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.

What you give updiffers

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.
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.
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.
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.
