Sauk (WI) Investor Pulse Report (2025-Q4)

Investor ownership in Sauk County is minimal, comprising just 72 single-family residential properties, which represents a scant 0.5% of the total 15,621 SFRs in the market.

The market is dominated by small, individual investors rather than corporations. Individuals own 55 properties (76.4% of the investor portfolio), while companies own the remaining 18 properties (25.0%).

This individual dominance is also reflected in the entity count, with 77 individual landlords compared to just 16 company landlords, demonstrating a local market driven by small-scale operators.

Within the investor portfolio, ownership is nearly evenly split between leveraged and unleveraged assets. Landlords hold 34 properties with financing, while 38 properties are owned free-and-clear with cash.

The primary purpose of these holdings is clear, with 52 of the 72 properties (72.2%) actively rented, confirming a strong focus on generating rental income within this small investor community.

Contrary to typical market behavior, landlords in Sauk County paid a significant premium for properties in Q4 2025. The average landlord acquisition price was $424,000, which is 16.6% higher than the $363,782 paid by traditional homeowners—a difference of $60,218.

The price gap between landlords and homeowners has been extremely volatile throughout the year. While landlords paid a premium in Q2 ($121,360 or 31.1%), Q3 ($6,673 or 1.9%), and Q4, they achieved a substantial 30.4% discount in Q1, paying $114,833 less than homeowners.

This volatility suggests that low transaction volume allows single, high-priced acquisitions to heavily skew quarterly averages, rather than indicating a consistent market-wide trend.

Overall, investor acquisition prices have trended upward significantly. The average price paid in 2025 ($391,646) is a notable increase from the 2024 average of $304,450.

This recent price escalation also surpasses the pandemic-era boom, where the average price from 2020-2023 was $303,100, signaling a recent acceleration in the cost of entry for investors in this market.

Investor activity in Sauk County's housing market was nearly non-existent in Q4 2025. Landlords purchased only 1 single-family home out of a total of 170 sold, capturing a marginal 0.6% of the market's sales activity.

The entirety of this quarter's landlord purchasing activity came from a single institutional investor from the 1000+ property tier. This one transaction represented 100% of all landlord acquisitions.

In a stark display of inactivity, mom-and-pop landlords (1-10 properties) made zero acquisitions in Q4. This demographic, which constitutes the vast majority of ownership in the county, paused its buying completely.

Similarly, mid-size landlords (11-1000 properties) were also absent from the market, recording no purchases during the final quarter of the year.

The data reveals a market where the dominant small investor base has stepped back, leaving a single large-scale investor to account for all landlord-driven acquisition activity in Q4.

The investor landscape in Sauk County is overwhelmingly dominated by small-scale operators. Mom-and-pop landlords, who own between 1 and 10 properties, collectively hold 88.9% of all investor-owned single-family homes.

Single-property landlords (Tier 01) form the bedrock of the market, owning 49 properties. This single tier accounts for 68.1% of the entire investor portfolio, highlighting the highly fragmented nature of ownership.

Despite recent media focus on large investors, institutional players (1000+ properties) have a negligible footprint in the county. They own just 2 properties, representing only 2.8% of the investor-owned housing stock.

Mid-size investors (11-1000 properties) also have a very limited presence, collectively owning only 6 properties, or 8.4% of the total investor portfolio.

This distribution underscores a market defined by local, small-scale investment, where the influence of large, corporate, and institutional landlords is minimal compared to the dominant mom-and-pop segment.

Individual investors form the foundation of Sauk County's landlord market, particularly at the entry level. Within the single-property tier, individuals own 45 of the 50 properties, a commanding 90.0% share.

This pattern of individual dominance continues into slightly larger portfolios. Among landlords owning 3-5 properties, individuals control 9 properties, representing a 75.0% majority compared to the 3 properties (25.0%) owned by companies.

In the two-property tier, ownership is exclusively individual, with a single property held by a person and zero by companies.

Unlike in larger metropolitan markets, there is no observable crossover point in Sauk County where companies become the majority owners. Individuals maintain control across all smaller portfolio tiers for which data is available.

This data illustrates a market where corporate ownership is a minority strategy, and the path to building a rental portfolio is almost exclusively pursued by individual investors.

Investor ownership in Sauk County is thinly spread, lacking any significant geographic concentration. The zip code with the most investor-owned properties, 53578 (Prairie Du Sac), contains only 5 such homes.

Other top areas by count, like 53561 (Lodi) and 53583 (Reedsburg), each have just 3 investor properties, reinforcing the low-density nature of rental ownership.

Ownership rates are negligible throughout the county, failing to surpass 1% in any zip code. The highest rate is found in 53556 (Lake Delton) at just 0.7%, followed by 53561 (Lodi) at 0.6%.

The data shows no correlation between areas with the highest count and the highest percentage of ownership, primarily because the total numbers are too small to establish a meaningful pattern.

Overall, the geographic analysis reveals that Sauk County is not a target for concentrated investor activity, with ownership distributed in very small numbers across various local communities.

After a consistent period of accumulation, landlord transaction activity in Sauk County balanced out in Q4 2025. Investors recorded 1 purchase and 1 sale, resulting in a net neutral position and halting portfolio growth for the quarter.

This Q4 activity represents a marked deceleration from earlier in the year. In Q3 2025, landlords were strong net buyers with a 2-to-1 buy/sell ratio (6 buys vs. 3 sells), and in Q2 they were even more aggressive with a 3-to-1 ratio (6 buys vs. 2 sells).

Despite the quiet end to the year, landlords were net buyers for 2025 overall. They purchased 17 properties while selling 9, for a net gain of 8 properties across the county.

This trend of accumulation extends to the previous year as well. In 2024, landlords were even more active net buyers, acquiring 24 properties and selling only 10 for a net gain of 14 properties.

The historical data shows a consistent pattern of portfolio growth over the past two years, which only came to a halt in the most recent quarter.

In Q4 2025, landlords were a minimal force in Sauk County's real estate market, involved in only 1 of the 275 total SFR transactions, a share of just 0.4%.

All landlord transaction activity was driven by a single institutional investor (1000+ tier), who made one purchase at an average price of $424,000.

There was a complete absence of activity from the mom-and-pop segment (1-10 properties). These small investors, who own the vast majority of the county's rental stock, did not participate in any transactions during the quarter.

The sole institutional purchase was acquired from a non-landlord, meaning there was no inter-landlord trading activity observed in Q4. This indicates a lack of portfolio churning or sales between investors.

The Q4 data paints a picture of an extremely quiet quarter for investors, with the market's dominant small players on the sidelines and only a single, large outlier transaction taking place.
