Sully (SD) Investor Pulse Report (2025-Q4)

Sully County's SFR market demonstrates significant investor presence, with landlords owning 143 properties, accounting for a notable 43.1% of the total 332 SFR properties in the market. This reveals a highly landlord-penetrated local market.

The vast majority of investor-owned properties are held by individual landlords, who control 130 properties (90.9%), while company landlords own just 15 properties (10.5%). This structure heavily favors individual, "mom-and-pop" investors.

A striking pattern is the complete absence of financing in landlord acquisitions in Sully County; all 143 investor-owned properties were purchased with cash. This indicates a cash-heavy investment strategy, potentially driven by local market conditions or investor preferences.

Of the 143 landlord-owned properties, 142 are currently rented, signifying a near-total utilization for rental income. This 99.3% rental rate highlights the strong focus on generating passive income through property investment in Sully County.

The market structure in Sully County is overwhelmingly individual-investor centric, with 186 individual landlords compared to only 16 company landlords, a ratio of more than 11 individual investors for every company investor. This signals a market where smaller, local investors are the primary driving force.

Comprehensive analysis of landlord acquisition pricing and comparisons to traditional homeowners for Sully County, SD, is currently not possible due to the absence of relevant data in the provided datasets. Key metrics such as average acquisition prices for landlords, all purchasers, and traditional homeowners across various timeframes (Q4, Q3, earlier quarters, annual, and historical periods) are unavailable.

Consequently, insights into landlord discounts or premiums relative to traditional homeowners, including the percentage difference and dollar amount gap, cannot be established for the current quarter or historical periods. This limits understanding of investor buying strategies and market competitiveness in the region.

The lack of data also prevents an examination of how acquisition price trends may have evolved over time, such as appreciation from pandemic-era (2020-2023) to Q4 2025, or year-over-year changes. Therefore, it is impossible to identify any consistent or widening/narrowing price gaps.

Furthermore, without this data, any potential differences in acquisition prices paid by individual versus company landlords, or price variations across different investor tiers, cannot be analyzed. This restricts a deeper understanding of varying purchasing power or investment strategies among different investor segments in Sully County.

The absence of acquisition pricing data also impacts the ability to assess the number of properties acquired in each timeframe, thus hindering an analysis of acquisition velocity and market momentum from a pricing perspective.

Sully County experienced a complete standstill in the SFR purchase market during Q4 2025, recording zero total SFR purchases. This means neither landlords nor any other buyer types acquired properties in the county this quarter.

As a direct consequence of zero activity, landlords accounted for 0.0% of all Q4 SFR purchases. This indicates a highly inactive market for property acquisitions across all buyer segments during the latest quarter.

Given the absence of any landlord purchases in Q4, there was no identifiable activity from mom-and-pop landlords (Tier 01-04) or institutional investors (Tier 09), with both segments registering 0.0% of landlord purchases.

The lack of Q4 purchase data also means there were no new landlords (single-property, Tier 01) entering the market in Sully County this quarter, reflecting a pause in investor expansion.

Without any purchase transactions, it is impossible to analyze the number of entities active in each tier, their average properties per entity, or which tier might have had the highest concentration of Q4 activity. The market was entirely dormant for acquisitions.

Mom-and-pop landlords (Tiers 01-04) maintain absolute control of the investor-owned SFR market in Sully County, holding 100.0% of the 145 investor-owned properties. This highlights a market entirely dominated by smaller-scale, often local, investors.

Within the mom-and-pop segment, single-property landlords (Tier 01) are exceptionally dominant, owning 134 properties, which accounts for 92.4% of the total investor-owned SFR properties. This indicates that first-time or very small-scale landlords form the backbone of the rental market in Sully County.

The distribution drops off sharply after Tier 01, with two-property landlords (Tier 02) owning just 9 properties (6.2%), and both the 3-5 property (Tier 03) and 6-10 property (Tier 04) segments each owning only 1 property (0.7%). This signifies minimal growth beyond one or two properties for most landlords.

Notably, there is no presence of institutional investors (Tier 09, 1000+ properties) in Sully County, owning 0.0% of the investor-held SFR. This starkly contrasts with larger urban markets and suggests Sully County is not a target for large-scale corporate investment.

Due to missing data, analysis of how acquisition prices vary by tier is not possible. However, the complete dominance of smaller tiers clearly defines the market's investment landscape without influence from larger, potentially price-influencing, entities.

Individual investors overwhelmingly dominate company ownership across all active tiers in Sully County, owning 100% of properties in Tier 02 (9 properties) and Tier 03 (1 property). In the single-property Tier 01, individuals own 122 properties (89.7%), compared to 14 properties (10.3%) held by companies.

There is no crossover point where companies become the majority owners in any tier within Sully County; individual ownership remains dominant across all portfolio sizes present. This reinforces the "mom-and-pop" nature of the market.

Company ownership is restricted exclusively to the smallest tier (Tier 01), where they hold 14 properties. This suggests that any corporate investment that does occur is in very small, singular property holdings, rather than scaled portfolios.

The complete absence of company-owned properties in tiers above 01 (two properties and above) demonstrates that growth patterns for corporate investors in Sully County are virtually non-existent, unlike the individual investor landscape which extends up to 10 properties.

Due to missing data, it is not possible to compare acquisition prices between individual and company landlords within each tier, or to assess how growth patterns might differ by owner type based on pricing trends over time.

Within Sully County, the zip code SD-Sully-57564 stands out as the primary hub for investor-owned properties, containing 105 such properties. This concentration highlights it as the most significant sub-geography for landlord activity by absolute count.

While SD-Sully-57564 leads in total investor-owned properties, the zip code SD-Sully-57520 exhibits the highest rate of investor penetration, with 53.6% of its SFR properties being investor-owned. This indicates that over half the rental market in this specific area is managed by landlords.

The top three active sub-geographies by count are SD-Sully-57564 (105 properties), SD-Sully-57501 (23 properties), and SD-Sully-57520 (15 properties). These three zip codes collectively represent the vast majority of investor-owned SFR housing within Sully County.

The areas with the highest investor ownership rates, SD-Sully-57520 (53.6%) and SD-Sully-57564 (49.3%), both demonstrate significant landlord presence, indicating these are key rental markets within the county. SD-Sully-57501 follows with a 25.8% investor ownership rate.

Due to missing data for specific acquisition prices per zip code, it is not possible to analyze how acquisition prices vary across these geographic regions. However, the clear concentration of both count and percentage in these specific zip codes signals localized investment hot spots.

A comprehensive analysis of historical landlord transaction activity in Sully County is not feasible due to the complete absence of data in the provided datasets. This includes information regarding buy and sell transactions for all landlords across various timeframes (Q4, Q3, annual, and all-time).

Consequently, it is impossible to determine whether landlords in Sully County have been net buyers or net sellers over time, or to calculate a buy/sell ratio. This limits understanding of market direction and investor sentiment.

Without transaction data, insights into inter-landlord trading activity, such as the percentage of buy or sell transactions that occur between landlords, cannot be generated. This prevents an assessment of market liquidity and internal dynamics within the investor segment.

Similarly, average buy and sell prices for landlords cannot be compared to infer potential profit margins or market valuation trends, as all historical pricing data for transactions is missing.

Furthermore, the absence of data for institutional investors (1000+ Tier) transactions precludes any analysis of their specific buying, selling, or inter-landlord activity, and how their patterns might differ from the overall landlord market in Sully County.

The SFR market in Sully County experienced a complete cessation of transaction activity in Q4 2025, recording zero total transactions. This means no properties, whether for investment or owner-occupancy, were bought or sold during this period.

As a result, landlord transactions in Q4 2025 were also zero, leading to a 0.0% landlord share of the market. This highlights a period of no investor movement or liquidity in the county's housing market.

Neither mom-and-pop landlords (Tier 01-04) nor institutional investors (Tier 09) participated in any transactions during Q4 2025, with both segments registering zero activity. This indicates a county-wide pause in investment property trading.

Given the complete lack of transactions, it is impossible to determine average purchase prices by tier, or to identify which tiers might have paid the most or least. All average purchase prices for tiers, including Tier 01 and Tier 09, are reported as $0.

Without any recorded transactions, the extent of inter-landlord trading activity (properties bought from other landlords) cannot be assessed. This means that patterns of market liquidity and landlord-to-landlord reliance cannot be analyzed for Q4 2025.
