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

Landlords in Walworth County, SD, collectively own 774 SFR properties, representing a significant 40.7% of the total 1,902 SFR properties in the market. This highlights a substantial investor presence within the county's single-family housing sector.

Individual investors overwhelmingly dominate the landlord landscape in Walworth County, holding 704 properties, which accounts for 91.0% of all investor-owned SFR. This stands in stark contrast to company-owned properties, which total only 82 (10.6%), challenging narratives of large corporate control.

The prevalence of individual landlords is further emphasized by entity counts, with 824 individual landlords compared to just 60 company landlords, indicating a market primarily driven by smaller, often local, investors.

A striking pattern in Walworth County is the financing structure of landlord-owned properties: 100% of the 774 properties were acquired with cash, with 0 recorded as financed. This suggests a highly capitalized investor base or a market where traditional financing for investment properties is less common or documented.

The portfolio's primary focus is clearly on rental income, as 761 of the 774 landlord-owned properties are currently rented. This confirms that nearly all investor-held SFR properties in Walworth County are non-owner-occupied and actively contributing to the rental housing supply.

A critical observation for Walworth County, SD, is the complete absence of SFR acquisition pricing data for Q4 2025. This indicates that no purchases were recorded for landlords, all purchasers, or traditional homeowners during the current quarter.

This lack of data extends to all historical timeframes, including Q3, Q2, Q1 2025, the full year 2024, and the 2020-2023 pandemic-era boom. Consequently, it is impossible to establish any trends or patterns in acquisition prices over time.

Without any recorded purchase prices, a direct comparison between landlord acquisition costs and those of traditional homeowners cannot be made. This leaves a significant gap in understanding investor market dynamics in Walworth County.

The absence of pricing data also prevents any analysis of whether individual or company landlords pay different prices for properties, or if any price appreciation occurred from prior periods to the current quarter.

The zero acquisition data across all timeframes and buyer types suggests either an extremely illiquid market with no recent transactions or a limitation in the available data capturing such activities within Walworth County, SD.

Walworth County, SD, recorded a complete absence of SFR purchase activity during Q4 2025, with 0 total SFR purchases. This extends to landlords, who also made 0 acquisitions, representing 0.0% of the market.

The lack of any recorded purchases means that no new landlords, including single-property (Tier 01) investors, entered the market in Q4 2025. This points to a stagnant acquisition environment for the quarter.

Consequently, there is no activity to distribute across investor tiers, with both mom-and-pop landlords (Tier 01-04) and institutional investors (Tier 09) registering 0 purchases. This makes it impossible to determine which tiers are most active or their respective market shares for the quarter.

The complete lack of Q4 purchase data prevents any assessment of average properties per entity by tier or the concentration of recent buying activity among different investor sizes in Walworth County.

This data gap for Q4 2025 strongly suggests an extremely inactive period for SFR sales in Walworth County, or a significant limitation in the comprehensive tracking of such transactions within the provided dataset.

In Walworth County, SD, mom-and-pop landlords (Tiers 01-04) collectively control an overwhelming 97.1% of all investor-owned SFR properties. This translates to 796 properties, solidifying their dominant position in the county's rental housing market.

The bedrock of this market is the single-property landlord (Tier 01), who alone accounts for 546 properties, representing 66.6% of the total investor-owned portfolio. This highlights the foundational role of first-time or minimal investors.

In stark contrast to the mom-and-pop dominance, institutional investors (Tier 09, 1000+ properties) own a negligible share, controlling only 1 property, which equates to 0.1% of the total investor-owned SFR. This strongly refutes the perception of institutional takeover in this specific market.

While no specific acquisition pricing data is available by tier for Walworth County, the distribution clearly shows that the market structure is heavily skewed towards smaller, local investors rather than large-scale corporate entities.

The detailed tier distribution reveals that even beyond single-property owners, smaller portfolios continue to dominate: two-property landlords (Tier 02) hold 99 properties (12.1%), and small landlords with 3-5 properties (Tier 03) own 115 properties (14.0%).

Individual investors exert substantial control across all observed portfolio tiers in Walworth County, SD. Even in the largest listed tier (11-20 properties), individuals own 72.7% (16 properties), compared to companies at 27.3% (6 properties).

The dominance of individuals is most pronounced in the smallest tiers, with single-property owners (Tier 01) being 93.2% individual (518 properties) versus 6.8% company-owned (38 properties). This pattern continues for two-property owners (Tier 02), where individuals hold 89.9% (89 properties).

The data does not indicate a crossover point where company ownership surpasses individual ownership within the detailed tiers provided (up to 11-20 properties), suggesting that individual investors maintain significant control even as portfolio sizes grow.

For small landlords (3-5 properties), individuals own 88.7% (102 properties) compared to companies at 11.3% (13 properties). In the 6-10 property tier, individuals still constitute the majority at 63.9% (23 properties), while companies hold 36.1% (13 properties).

Given that institutional investors (Tier 09, 1000+ properties) account for only 1 property in the entire county, their impact on the individual vs. company split at higher tiers is minimal, further emphasizing the individual-centric nature of this market.

Walworth County, SD, exhibits highly concentrated landlord ownership within specific zip codes. The zip code SD-Walworth-57420 stands out with an exceptionally high investor ownership rate of 96.4%, indicating that nearly all SFR properties in this area are landlord-owned, although it accounts for only 27 properties.

In terms of sheer volume, the SD-Walworth-57601 zip code leads with 407 investor-owned properties, making it the most significant hub for landlord activity by count in the county. However, its ownership rate is 30.7%, much lower than the rate leaders.

Three distinct zip codes in Walworth County demonstrate an investor ownership rate exceeding 68.0%: SD-Walworth-57420 (96.4%), SD-Walworth-57452 (72.5%), and SD-Walworth-57472 (68.2%). This signals specific geographic areas with deep investor presence.

A notable contrast exists between the regions with the highest counts and those with the highest percentages. For instance, SD-Walworth-57601 has the most properties but ranks fifth in ownership rate, while SD-Walworth-57420 has fewer properties but nearly universal investor ownership. This suggests varied market dynamics across the county's sub-geographies.

The high concentration of investor-owned properties in these top zip codes underscores that while landlords hold 40.7% of the SFR market county-wide, their impact is intensely localized in certain areas, potentially shaping local housing supply and rental market conditions.

Walworth County, SD, lacks any recorded historical transaction data for all landlords, including buy and sell counts, inter-landlord percentages, and average prices. This pervasive absence of data prevents any assessment of landlord market activity or historical investment trends.

Similarly, institutional investors (1000+ tier) also show zero transactions across all historical timeframes. This means there is no data to determine their net buying or selling position, or to analyze their specific transaction patterns compared to the broader landlord market.

Without any buy or sell transaction counts, it is impossible to calculate a buy/sell ratio for landlords in Walworth County. Consequently, their overall market position as net buyers or sellers remains undetermined from the available data.

The absence of buy and sell price data also precludes any analysis of implied profit margins for landlords or how prices have trended over various timeframes, such as quarter-over-quarter or annually.

This complete data gap for historical transactions strongly suggests either an extremely illiquid market where investor transactions are rare, or a significant limitation in the dataset's ability to capture such activity within Walworth County, SD.

Walworth County, SD, experienced a complete absence of SFR transactions in Q4 2025, with 0 total transactions recorded. This means landlords also registered 0 transactions, resulting in a 0.0% share of the quarterly market activity.

The lack of any Q4 transaction data prevents any analysis of transaction volumes across investor tiers. All tiers, from single-property (Tier 01) to institutional (Tier 09), show 0 transactions for the quarter.

Consequently, it is impossible to determine average purchase prices by tier, nor to assess if certain tiers paid more or less for properties during Q4. The price spread between the highest and lowest tier is also undeterminable.

No inter-landlord trading activity (properties bought from other landlords) was recorded in Q4, meaning no insights can be drawn on market liquidity or the percentage of transactions occurring between investors for any tier.

This universal absence of transaction data for Q4 2025 reinforces the observation of an extremely inactive or unrecorded market for SFR sales and purchases involving landlords in Walworth County, SD.
