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

Investor ownership in Sully County, SD is exceptionally high, with landlords holding 143 out of 332 total SFR properties, a market penetration of 43.1%. This indicates a significant portion of the county's housing stock is comprised of rental properties.

The market is overwhelmingly dominated by individual investors, who own 130 properties (90.9%), compared to just 15 properties (10.5%) held by companies. This structure points to a classic mom-and-pop landlord environment rather than one with corporate presence.

A striking financial characteristic of this market is the complete absence of leverage; 100% of the 143 investor-owned properties are held as cash assets, with zero financed properties recorded. This suggests investors in this area are not reliant on debt for their acquisitions.

The portfolio is almost entirely dedicated to rentals, with 142 of the 143 properties classified as non-owner-occupied. This 99.3% rental rate underscores the clear business focus of property owners in the region.

The number of individual landlords (186) far outweighs company landlords (16), reinforcing the profile of a market built on small-scale, personal real estate investing.

A defining feature of the Sully County real estate market is the absence of recent, comparable sales data for both investor and traditional homeowner purchases. This lack of transactional information prevents any meaningful analysis of acquisition prices.

Consequently, it is impossible to determine whether landlords pay a premium or a discount compared to traditional homeowners in this specific geography. The data void suggests an extremely low-velocity market with minimal turnover.

Analysis of pricing trends, such as quarter-over-quarter changes or appreciation since the 2020-2023 period, cannot be performed. The market appears to be characterized by long-term holds rather than frequent buying and selling.

There is no data to compare pricing strategies between individual and company investors, further highlighting the market's current inactivity.

Investor purchasing activity in Sully County was non-existent in Q4 2025, with landlords acquiring zero properties. This reflects a total of zero SFR purchases across the entire market for the quarter.

The lack of activity was universal across all investor sizes. Mom-and-pop landlords (Tiers 01-04) made zero acquisitions, consistent with the market-wide stagnation.

Similarly, institutional investors (Tier 09) also recorded zero purchases, though their presence in the county is nil to begin with. The data shows no new capital flowing into the market from investors of any scale.

No new landlords entered the market in Q4, as indicated by the zero purchases in the single-property (Tier 01) category. This points to a static ownership landscape with no new entrants.

The investor landscape in Sully County is exclusively composed of mom-and-pop landlords, who own 100% of the 143 investor-held properties. There is no mid-size or institutional ownership, making it a market of small-scale investors.

Single-property landlords (Tier 01) are the most significant group, holding 134 properties, which accounts for 92.4% of the entire investor portfolio. This highlights the granular nature of ownership in the county.

The remaining investor properties are held by landlords with 2 to 10 properties, solidifying the complete control of the small investor segment. For instance, landlords with two properties hold 9 homes (6.2% of the portfolio).

Due to the lack of recent transactions, there is no pricing data available to analyze if larger landlords pay more or less than smaller ones. The market's structure is static and does not reflect active trading.

Institutional investors in Tier 09 have absolutely no footprint in Sully County, owning 0.0% of the investor-held housing stock.

Individual investors are the definitive majority owners across all portfolio sizes in Sully County. In the largest tier, single-property owners, individuals hold 122 properties (89.7%) while companies own just 14 (10.3%).

There is no crossover point where companies overtake individuals. In fact, company ownership is confined to the smallest tier and non-existent in larger local portfolios, such as the two-property tier where individuals own 100%.

The data clearly shows that company investment is extremely limited, with their entire footprint consisting of 14 single-property holdings. This structure is the inverse of markets with significant corporate landlord activity.

Without any recent sales data, it is impossible to compare the acquisition prices or buying strategies between individual and company landlords within any tier.

Geographic concentration of investor ownership is stark in Sully County. The zip code 57564 is the epicenter of activity, containing 105 of the 143 total investor-owned properties and showing a high ownership rate of 49.3%.

While 57564 has the highest count, zip code 57520 exhibits the highest investor penetration rate at 53.6%. This means investors own more than half of the SFR housing stock in that area.

Another key area is zip code 57501, which has 23 investor-owned properties, translating to a significant 25.8% ownership rate. This demonstrates that investor presence is substantial even outside the main hub.

The data shows a clear pattern where the areas with the highest count of investor properties also have some of the highest ownership percentages, unlike in larger markets where these two metrics often diverge.

Analysis for several zip codes, such as 57522 and 57536, was not possible due to a lack of property data, suggesting very little or no SFR housing in those areas.

A complete lack of historical transaction data for Sully County makes it impossible to conduct any analysis of landlord buying and selling behavior. Key metrics like buy/sell ratios cannot be calculated.

It cannot be determined whether landlords are net buyers or net sellers, a crucial indicator of market direction. The data suggests a highly illiquid market where properties are rarely traded.

The frequency of inter-landlord transactions, which reveals the maturity and interconnectedness of an investor market, is unknown. There is no information on whether landlords are selling to each other or to other buyer types.

Similarly, no market reports can be generated on the transaction patterns of institutional investors, as they have no presence and there are no recorded transactions.

Without buy and sell prices over time, analyzing potential profit margins or price appreciation from historical transactions is not feasible.

The transaction market in Sully County was entirely dormant in Q4 2025, with zero total SFR transactions recorded. This means landlords were involved in 0% of market activity.

This inactivity was consistent across all investor sizes. Mom-and-pop landlords (Tiers 01-04), who own 100% of the investor properties, did not participate in any transactions during the quarter.

There were no recorded instances of inter-landlord trading. The percentage of properties bought from other landlords was 0%, as no acquisitions occurred.

Due to the zero-transaction environment, there is no average purchase price data available for any tier. It is impossible to assess whether different-sized investors employ different pricing strategies.

The transactional inactivity stands in stark contrast to the high ownership concentration, suggesting the market is built on long-term holds rather than active trading for capital gains.
