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.

Waterdiffers

Green Valley
Not a single system. The Rapid Valley Sanitary District's service area extends past the Rapid Valley boundary and is the likely supplier for much of Green Valley, and there is also a separate Green Valley Sanitary District administered alongside it. Outlying parcels toward Radar Hill and Reservoir Road are on private wells. Confirm per parcel.
Keystone
Town of Keystone municipal water inside the limits, drawn from town wells, with no violations on its current record. Parcels outside the town limits are on private wells.

Sewerdiffers

Green Valley
District sewer where the district reaches, private septic where it does not. Confirm per parcel.
Keystone
Confirm with the town before you rely on it. The town operates public works, but I have not been able to verify from the public record whether it runs a collection system or which parcels it reaches. Outside the limits, expect private septic.

Short term rentalsdiffers

Green Valley
Unincorporated county, so no municipal short-term rental ordinance applies. County zoning and any subdivision covenants govern, and state licensing applies once you rent.
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.

Healthcarediffers

Green Valley
The Monument Health Rapid Valley Clinic on Elderberry Boulevard for walk-in care, with the hospital in Rapid City.
Keystone
No clinic in town. Monument Health Custer Hospital has a 24 hour emergency department, and Rapid City has the larger hospital.

Recreationdiffers

Green Valley
Open prairie, the county land east of town, and the whole Black Hills half an hour the other direction.
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.

The trade

An 1883 mining camp turned tourism town at the gateway to Mount Rushmore, 240 residents and millions of visitors.

What you gaindiffers

Green Valley
More ground for the money six miles from Rapid City, with Ellsworth fifteen minutes north.
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

Green Valley
A school district line that runs through the community, and a water arrangement that changes street to street.
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.
