Custer, SD Sees Over Half of Home Sales Close Off-Market in July 2026
With 53.0% of all recorded home sales occurring outside the Multiple Listing Service (MLS), Custer County, South Dakota, presents a distinct landscape for real estate investors.
In July 2026, Custer County recorded a total of 230 home sales, with a significant majority transacting off-market. This indicates a robust segment of private sales activity, often favored by investors and wholesalers seeking properties that do not reach the broader public market. According to BatchData's On Market vs Off Market Sold Report, 122 sales in Custer County were classified as off-market, representing 53.0% of all transactions. In contrast, on-market sales accounted for 108 properties, or 47.0% of the total, suggesting that nearly an equal number of properties are changing hands privately as through traditional channels. This blend highlights a dynamic local market where opportunities may exist outside of typical listings.
County Overview
The prevalence of off-market transactions in Custer County points to an active network of buyers and sellers engaging in direct deals. This 53.0% off-market share signals that a substantial portion of the local housing inventory is being traded without the exposure of the open market, often involving investor-to-investor transactions, direct-to-seller purchases, or other private arrangements. For real estate investing professionals, a high off-market percentage like this suggests potential for sourcing deals through channels beyond the MLS, such as direct mail campaigns, networking, or utilizing advanced property data to identify motivated sellers. The 122 off-market sales in July 2026 demonstrate a consistent flow of private deal-making within the county, offering a distinct advantage to those equipped to find and close these transactions.
Conversely, the 108 on-market sales, comprising 47.0% of the total, represent the traditional route where properties are listed and sold through real estate agents on the MLS. While still a significant portion of the market, the fact that on-market sales are slightly outnumbered by off-market transactions underscores the unique character of Custer County's real estate environment. This split indicates that while traditional avenues remain relevant, a considerable amount of deal flow is happening below the surface, which is a critical insight for anyone looking to gain a competitive edge in the area. Understanding this dual market dynamic is essential for developing comprehensive acquisition strategies that can capitalize on both private and publicly listed opportunities.
Local Market Context
Within South Dakota, Custer County holds a notable position despite its relatively smaller contribution to the state's overall sales volume. The county ranked #14 out of 58 counties for total sales in July 2026, indicating a respectable level of activity. However, Custer County accounted for just 1.8% of the state's total sales of 13,100, suggesting that while local activity is consistent, it represents a concentrated segment rather than a dominant share of the broader South Dakota market. This smaller share means that Custer County's market dynamics, particularly its high off-market activity, are likely more localized and less influenced by the statewide average composition.
The substantial 53.0% off-market share in Custer County diverges from what might be expected in larger, more liquid markets where on-market transactions typically dominate. This distinct mix implies that Custer County's market structure is particularly conducive to private deal flow, possibly driven by factors such as a higher concentration of investor interest, a strong local network for private sales, or properties that are less likely to be listed publicly due to their condition or seller motivations. For investors, this creates a compelling environment where leveraging bulk data delivery and skip tracing services can be especially effective for identifying off-market leads. The specific composition of sales in Custer County highlights that while the county contributes a modest percentage to the state's overall sales, its internal market mechanics offer a unique opportunity for those focused on non-traditional acquisition methods. This specific characteristic of the Custer County market suggests that sophisticated data tools and targeted outreach are crucial for uncovering the best deals.
