Custer (SD) Investor Pulse Report (2026-Q1)

In Custer County, investors hold a significant 778 single-family residential properties, representing 25.1% of the total 3,099 SFRs in the market. This high penetration rate indicates a strong presence of real estate investing activity relative to the market's size.

The ownership structure is overwhelmingly dominated by individuals. Individual investors own 711 properties, or 91.4% of the investor-owned portfolio, while companies own the remaining 80 properties (10.3%).

A defining characteristic of this market is the preference for cash transactions. A staggering 752 investor-owned properties are held free and clear, compared to only 26 that are financed. This reveals a well-capitalized investor base that does not rely heavily on leverage.

The entity count further underscores the dominance of small-scale investors, with 1,089 individual landlords operating in the market compared to just 76 companies. This dynamic points to a market driven by personal capital rather than corporate investment strategies.

Nearly all investor properties are classified as rentals, with 771 listed as rented, confirming that the vast majority of the 778-property portfolio is actively used for investment purposes rather than secondary homes.

In a striking deviation from typical market behavior, Custer County landlords have historically paid more than traditional homeowners. In Q1 2025, landlords' average acquisition price was $396,857, a premium of $40,846 (11.5%) over the homeowner average of $356,011.

This trend appeared to accelerate into the second quarter of 2025, with the average landlord price listed at $772,500 compared to the homeowner price of $533,760. This represents a substantial 44.7% premium, or $238,740.

Crucially, the acquisition data for 2025 shows zero properties purchased by landlords in Q1 and Q2. This indicates that the reported average prices are not based on actual transaction volumes and may represent aspirational list prices or data from a very small, unrecorded sample, signaling a potential market freeze.

Looking at a broader timeframe, average acquisition prices for investors during the 2020-2023 period were $321,745. The listed price for 2024 acquisitions was significantly higher at $485,986, showing substantial price appreciation leading up to the recent market stall.

The most recent quarter saw a complete cessation of investor purchasing activity in Custer County. Landlords were responsible for zero of the SFR purchases, accounting for 0.0% of the market share.

This market-wide freeze affected investors of all sizes. Mom-and-pop landlords, who constitute the entirety of the local investor base, made no new acquisitions during this period.

Similarly, there was no activity from institutional-level investors, which is consistent with their overall 0.0% ownership share in the county.

The lack of new purchases indicates a significant shift in market dynamics, potentially driven by pricing, inventory, or broader economic factors, leading investors to pause their acquisition strategies entirely.

The investor landscape in Custer County is exclusively composed of small-scale operators. Mom-and-pop landlords, defined as those owning 1-10 properties, control 100.0% of the 778 investor-owned SFRs.

The market is exceptionally granular, with single-property landlords (Tier 01) forming the bedrock. This group owns 732 properties, which constitutes a massive 92.8% of the entire investor portfolio.

The next largest tier, two-property landlords, holds just 35 properties (4.4%), while investors with 3-5 properties own 20 (2.5%). This demonstrates a steep drop-off in portfolio size beyond a single rental unit.

There is no presence of mid-size (11-1000 properties) or institutional (1000+ properties) investors in Custer County. This absence of large-scale players confirms the market's character as one driven entirely by local, small-scale investment.

Across all portfolio sizes in Custer County, individual investors consistently hold the majority of properties. In the single-property tier, individuals own 676 of the homes (91.2%) compared to 65 owned by companies.

This pattern continues into larger tiers. For two-property portfolios, individuals own 26 properties (74.3%) versus 9 for companies. In the 3-5 property tier, individuals hold 16 properties (69.6%) while companies own 7.

Unlike larger metropolitan markets, there is no crossover point where company ownership surpasses individual ownership. Even in the largest local tier (6-10 properties), individuals own 100% of the 2 properties recorded.

This data confirms that company or corporate investment structures are a minority strategy in this market, with personal ownership being the standard across the board, regardless of portfolio size.

Geographic analysis reveals that investor ownership in Custer County is not evenly distributed but is heavily concentrated in a few key areas. The zip code 57730 is the epicenter of activity, with 471 investor-owned properties, representing an ownership rate of 24.2%.

Some smaller zip codes exhibit exceptionally high investor penetration rates, suggesting they are likely vacation or recreational markets. For example, 57773 is 80.0% investor-owned, and 57722 has a 64.9% investor ownership rate.

The concentration is stark: the top five zip codes by property count (57730, 57744, 57722, 57747, and 57735) collectively contain 742 properties, which is 95.4% of all investor-owned SFRs in the county.

This intense geographic focus highlights that investment strategies are targeted at specific sub-markets within the county rather than a broad, county-wide approach.

Historical transaction data from 2024 paints a picture of an active and acquisitive investor base in Custer County. Landlords purchased 35 properties while only selling 4 over the course of the year.

This activity establishes landlords as decisive net buyers, with a net gain of 31 properties to their portfolios. The buy-to-sell ratio of nearly 9-to-1 indicates a strong sentiment towards market entry and expansion during that period.

The lack of any recorded transactions for institutional-tier investors (1000+ properties) is consistent with their 0% ownership stake. The transaction market, like the ownership market, is driven exclusively by smaller landlords.

The robust buying activity in 2024 provides a critical baseline that highlights the severity of the market freeze observed in the most recent quarter, where transaction volume fell to zero.

In the most recent quarter, landlords were completely inactive in the Custer County transaction market, accounting for 0.0% of all SFR transactions with zero recorded deals.

This halt in activity was universal across all investor sizes. Mom-and-pop landlords (Tiers 01-04), who make up 100% of the investor base, recorded zero transactions.

Consequently, there was no inter-landlord trading activity. The percentage of properties bought from other landlords was 0%, as no acquisitions occurred.

The average purchase price across all tiers was $0, reinforcing that the market for investor acquisitions was entirely dormant during this period. This contrasts sharply with the active buying seen in 2024.
