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.

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.

Rapid Valley Sanitary District serves portions of the area, while properties outside district service may use private wells and septic systems.	Mixed, municipal service in town with well and septic outside it	City water and sewer inside the limits
Waterdiffers	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.

Parcels outside the town limits are on private wells.	Town of Wall municipal water inside the limits. Rural parcels are on private wells.
Sewerdiffers	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.	Rapid Valley Sanitary District owns and maintains the collection system, and Rapid City treats the wastewater under an intergovernmental agreement. Parcels outside the district are on private septic.	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.

Short term rentalsdiffers	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.	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.	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.	This is genuine seasonal tourism territory at a national park gate. Confirm any town requirement, and note that Wall Drug houses many of its own seasonal workers, which removes demand from the local rental market.

Recreationdiffers	Creek bottoms, hay ground and hunting country, with Spearfish Canyon and the northern Hills half an hour away.	Rapid Creek, the county parks east of town, and everything the Hills offer half an hour west.	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.	Badlands National Park about seven miles south, Buffalo Gap National Grassland all around, the National Grasslands Visitor Center on Main Street and the Wall rodeo arena.
The trade
Housing and patterndiffers	An 1891 French-Canadian railroad townsite that is now a cattle auction crossroads and an acreage corridor.	The region's largest unincorporated community: suburban streets, high ownership, county government.	An 1883 mining camp turned tourism town at the gateway to Mount Rushmore, 240 residents and millions of visitors.	A complete small prairie town with its own school, clinic and grocery, at the northern gate to the Badlands.
What you gaindiffers	The cheapest ground in the northern Hills that still puts you eleven miles from a hospital and sixteen from three towns.	Rapid City schools and a five mile commute without Rapid City property taxes, plus a walk-in clinic in the neighborhood.	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.	Everything a town needs in one place, 50 miles from the city, at prairie prices.
What you give updiffers	A three-way school district split you have to verify per parcel, and no services of any kind in town.	No city services, a sanitary district bill instead of a city utility bill, and an annexation line that only the parcel record can settle.	A seasonal town with no school, no grocery and no clinic, and a housing stock where half the doors are dark in winter.	Fifty miles to a hospital and to real shopping, and an economy that runs on a three month season.

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.
