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.

Housing and lots
Typical pricediffers	No figure published. St. Onge is Mount Rushmore Area MLS territory and the current feed covers only the Black Hills MLS, so a zero here would be a gap in the data rather than a fact about the market.	One single family sale shows in the Black Hills MLS over 24 months, at $80,000. One closing is a sample of one rather than a price level, so read it that way.	$400k to $600kMedian sold $475,000.

Utilities and rules

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.

Short term rentalsdiffers	Unincorporated Lawrence County, so no municipal ordinance applies.

What you gaindiffers	The cheapest ground in the northern Hills that still puts you eleven miles from a hospital and sixteen from three towns.	Eighteen minutes from the hospital in Hot Springs, with 600,000 acres of grassland out the door and one MLS closing in two years to price from.	A downtown you can walk across, Black Hills State and Spearfish Canyon out the back door, on city water and sewer.	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	A three-way school district split you have to verify per parcel, and no services of any kind in town.	No school, no store and no services in town, an aging water system with an open compliance item, and an undocumented sewer situation.	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.	A seasonal town with no school, no grocery and no clinic, and a housing stock where half the doors are dark in winter.

Buffalo Gap: No school, no store and no services in town, an aging water system with an open compliance item, and an undocumented sewer situation.
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.
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.

Considering a home here?

Send the address and we can talk it through. The details that change from one property to the next are jurisdiction, water and sewer, the school the district assigns, covenants, road maintenance and the rest of what never shows up on a listing.
