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

Real estate investors have a substantial footprint in Sanborn County, owning 267 single-family properties, which constitutes 45.7% of the total 584 SFRs in the market.

Ownership is overwhelmingly concentrated among small, individual landlords, who own 256 of the 267 properties (95.9%). Companies own the remaining 15 properties, a mere 5.6% share, underscoring the local, non-corporate nature of the rental market.

A defining characteristic of this market is its lack of leverage. All 267 investor-owned properties were acquired with cash, with 0 properties currently financed. This suggests a financially conservative investor base focused on long-term holds rather than leveraged growth.

The portfolio is entirely dedicated to rentals, with 100% of the 267 properties classified as non-owner-occupied. This highlights the critical role these investors play in providing housing for the local community.

The disparity between entity types is stark, with 343 individual landlords compared to just 15 company landlords. This 23-to-1 ratio of individuals to companies further confirms that the Sanborn County rental market is driven by local residents, not large corporations.

A complete absence of transactions in the most recent quarter for both landlords and traditional homeowners makes a direct price comparison impossible for this period.

Analysis of pricing trends is also precluded by the lack of recent sales velocity. Data for Year 2024 and the 2020-2023 period shows zero properties were purchased by landlords, indicating that the current holdings are the result of acquisitions made in earlier periods.

The lack of recent, comparable sales data is a key insight into the nature of the Sanborn County market. It points to a highly stable, illiquid environment where properties are held for the long term and do not frequently trade hands.

Without transaction data, it is not possible to assess if a 'landlord discount' exists in this market or how pricing has appreciated over time. The market appears to be defined by buy-and-hold strategies rather than active trading.

The fourth quarter of 2025 was marked by a total lack of acquisition activity in Sanborn County's SFR market. Landlords purchased 0 of the 0 total properties sold, reflecting a market at a standstill.

This inactivity was uniform across all investor sizes. Mom-and-pop landlords (1-10 properties) recorded zero purchases, as did mid-size and institutional tiers.

No new landlords entered the market during the quarter. The number of single-property landlords, a key indicator of new investor formation, remained unchanged as there were no new purchases in Tier 01.

The complete halt in purchasing activity suggests a market characterized by owner satisfaction with current holdings, a lack of available inventory for sale, or a combination of both factors.

This contrasts sharply with more dynamic markets and highlights Sanborn County as a case study in market stability and low liquidity, where portfolio growth through acquisition is not currently occurring.

The investor landscape in Sanborn County is exclusively composed of small-scale operators. Mom-and-pop landlords, defined as those owning 1-10 properties, control 100% of the 267 investor-owned SFRs.

Within this group, single-property landlords (Tier 01) form the bedrock of the market. They own 249 properties, accounting for a commanding 91.2% of all investor-owned housing.

The market structure is highly fragmented at the smallest level. Following single-property owners are two-property landlords with 16 properties (5.9%) and small landlords with 3-5 properties holding 8 properties (2.9%).

There is absolutely no institutional investor (Tier 09, 1000+ properties) presence in Sanborn County. This market completely defies the narrative of large corporate landlords and is a pure example of a locally-owned rental ecosystem.

Due to the lack of transactions, it is not possible to analyze how acquisition prices might vary by tier. The ownership structure has remained static in recent periods.

Individual investors overwhelmingly dominate every ownership tier in Sanborn County. There is no 'crossover point' where companies become the majority owners; individuals maintain control across the board.

In the largest tier present (3-5 properties), individuals own 7 of the 8 properties (87.5%), while a single property is company-owned.

The dominance is even clearer in smaller tiers. Individuals own all 16 properties (100%) in the two-property tier and 239 of 253 properties (94.5%) in the single-property tier.

Company ownership is a minor feature of this market. Companies own only 14 single-property rentals and 1 small portfolio property, for a total of 15 properties. This indicates that the corporate real estate investor model has not penetrated this geography.

With no recent transaction data available for either owner type within any tier, a comparison of acquisition pricing strategies between individuals and companies is not possible.

The majority of investor-owned properties in Sanborn County are located in just three zip codes. The 57385 zip code leads with 156 properties, followed by 57359 with 60 properties and 57314 with 50 properties.

Investor ownership rates, a measure of market penetration, are exceptionally high. The 57363 zip code shows a 100% investor ownership rate on its single SFR property, making it technically the most saturated.

More significantly, larger zip codes also show deep investor penetration. In 57359, nearly half of all SFRs (49.6%) are investor-owned, and in 57385, the rate is a similarly high 48.0%.

The 57314 zip code also has a substantial investor presence, with 36.8% of its SFRs owned by landlords. This demonstrates that high investor ownership is a widespread characteristic of the county, not an isolated phenomenon.

This geographic concentration reveals that specific communities within Sanborn County rely heavily on real estate investing to supply rental housing options.

The dataset for Sanborn County contains no historical transaction records, indicating a market with extremely low or nonexistent trading activity in the periods covered.

As a result, it is impossible to determine whether landlords have been net buyers or net sellers. The buy/sell ratio, a key indicator of market sentiment and direction, cannot be calculated.

Analysis of inter-landlord trading is also not possible. The data does not allow for a measurement of how many transactions occur between investors, which would otherwise signal market liquidity and maturity.

Similarly, a comparison of average buy prices versus sell prices cannot be performed. This analysis would typically provide insight into the potential profitability and capital appreciation within the market.

The lack of transaction data is itself the primary finding: Sanborn County is a 'buy-and-hold' market where investors retain their properties for extended periods, and transactional activity is not a defining feature.

The first quarter of 2026 was completely static for the Sanborn County SFR market, with a total of 0 transactions recorded. Consequently, the landlord share of transactions was 0.0%.

This lack of activity was consistent across all investor tiers. From single-property mom-and-pop landlords to larger portfolios, no investor bought or sold a property during the quarter.

There was no inter-landlord trading activity. The percentage of properties bought from other landlords was zero, as no purchases of any kind were made.

A price analysis by tier is not possible. The average purchase price for all tiers was $0, reflecting the absence of any sales.

The Q1 data confirms the trend of an inactive, stable market. Investors are holding their assets, and no new properties were transacted, suggesting a market in equilibrium or one with limited supply and demand pressure.
