Winnebago (WI) Investor Pulse Report (2026-Q1)

In Winnebago County, landlords hold a total of 3,001 Single-Family Residential (SFR) properties, accounting for 6.4% of the total 47,096 SFRs in the market. This represents a modest but significant portion of the local housing stock dedicated to rentals.

Individual investors are the primary force in the market, owning 1,906 properties, or 63.5% of the total investor portfolio. Companies own the remaining 1,129 properties (37.6%), showing that ownership is skewed towards smaller, non-corporate entities.

The entity count further emphasizes the dominance of small operators. Of the 3,179 distinct landlords, 2,532 are individuals compared to just 647 companies. This means individual operators make up 79.6% of all landlords, even though they control 63.5% of properties, indicating smaller average portfolio sizes compared to companies.

A significant majority of the investor-owned portfolio (2,795 properties, or 93.1%) is classified as rented. This high percentage confirms that the properties are actively part of the rental supply and not held for other purposes.

Financing data reveals that many investors are not heavily leveraged. A total of 1,773 properties (59.1%) were acquired with cash, compared to 1,228 (40.9%) that are financed. This suggests a stable investor base with substantial equity in their holdings.

In Q1 2026, landlords demonstrated a remarkable ability to acquire properties below market rates, paying an average price of $212,528. This was $116,580 less than the $329,108 paid by traditional homeowners, representing a staggering 35.4% discount.

This deep discount is part of a dramatic and volatile trend over the past year. In Q1 2025, landlords were actually paying a 6.3% premium over homeowners ($343,640 vs. $323,220). The market then shifted radically, with the landlord discount growing to 14.4% in Q2 2025 and peaking at 42.7% in Q3 2025.

The trend suggests landlords are not competing for the same on-market properties as traditional buyers. Instead, they appear to be targeting distressed, off-market, or value-add opportunities that allow for significantly lower acquisition costs.

While homeowner prices remained relatively stable, fluctuating between $323,220 and $338,973 over the last year, landlord prices have been far more erratic. This volatility underscores an opportunistic buying strategy that adapts to specific deals rather than broad market pricing.

The average landlord acquisition price has trended downward significantly, falling from a pandemic-era (2020-2023) average of $235,265 to just $212,528 in the most recent quarter. This indicates a strategic shift toward acquiring lower-cost assets.

In the fourth quarter of 2025, landlords acquired 54 of the 396 total SFR properties sold in Winnebago County, capturing a 13.6% share of the market's purchase activity.

The activity was overwhelmingly driven by small-scale investors. Mom-and-pop landlords (owning 1-10 properties) were responsible for 44 of these purchases, making up 80.0% of all investor acquisitions. This highlights the local, grassroots nature of the rental market.

In stark contrast, institutional investors (1,000+ properties) had no presence in the market, recording zero purchases in Q4. This absence underscores that large-scale capital is not a significant factor in Winnebago County's acquisition landscape.

The single-property tier was the most active segment, with 32 distinct entities purchasing 25 properties. This represents 45.5% of all landlord acquisitions and signals a healthy influx of new participants entering the real estate investing market for the first time.

Mid-size landlords also contributed to the activity, with those owning 11-100 properties acquiring a combined 11 homes, or 20.0% of the investor total. However, their volume was far surpassed by the smaller mom-and-pop operators.

The investor landscape in Winnebago County is defined by the dominance of small landlords. Investors owning 1-10 properties, often called mom-and-pop landlords, control a combined 89.4% of all investor-owned SFRs.

This concentration at the small end of the market directly contrasts with the minimal presence of large-scale investors. Institutional firms (1,000+ properties) own a mere 10 properties, representing just 0.3% of the investor portfolio. This finding challenges the narrative of widespread corporate ownership in the local market.

The single-property (Tier 01) landlord is the backbone of the rental market. This group alone owns 2,011 properties, which accounts for 66.0% of the entire investor-owned housing supply. Their share dwarfs every other investor tier combined.

Mid-size investors (11-1,000 properties) collectively own approximately 10.3% of the portfolio. While they represent a step up in scale, their combined ownership stake is still significantly smaller than even the third tier of small landlords (3-5 properties), who own 10.7%.

The ownership structure reveals a highly fragmented market composed of many small, independent operators rather than a consolidated market controlled by a few large players. The data from these market reports indicates that the path to scale is not a common one in this region.

A distinct crossover point occurs in ownership structure as investors scale their portfolios. While individuals dominate the entry-level tiers, companies become the majority property owner starting in the 3-5 property tier, where they control 175 properties (53.7%).

This transition from individual to corporate ownership is rapid. In the single-property tier, individuals own 1,658 homes, an 81.4% majority. However, by the 6-10 property tier, companies own 188 properties, representing a commanding 83.2% share.

The two-property tier acts as a transitional phase, with ownership almost evenly split: individuals hold a slight majority at 53.6% (89 properties), while companies hold 46.4% (77 properties).

This pattern strongly suggests that as landlords expand beyond their first or second property, they tend to incorporate their holdings into a formal business entity like an LLC for liability protection and financial management. This marks a shift from a personal investment to a professional operation.

The trend culminates in the 11-20 property tier, where company ownership reaches 95.1%. This confirms that building a mid-sized rental portfolio in Winnebago County is almost exclusively done under a corporate structure.

Investor ownership in Winnebago County is not evenly distributed but is instead highly concentrated in a few key areas. The 54901 zip code is the epicenter of this activity, home to 995 investor-owned properties, which is 33.2% of the county's entire investor portfolio.

This concentration of volume is matched by a high penetration rate. In the 54901 zip code, 12.6% of all SFR properties are investor-owned, the highest rate in the county and nearly double the county-wide average of 6.4%.

The top three zip codes by property count, 54901 (995 properties), 54956 (895 properties), and 54902 (592 properties), collectively account for 2,482 properties. This means a staggering 82.7% of all investor activity is clustered in just these three areas.

There is a notable difference between areas with high property counts and those with high ownership rates. For instance, the 54927 zip code has the third-highest ownership rate at 9.1%, but it does not appear in the top five by sheer volume, suggesting it is a smaller market with intense investor focus.

Conversely, the 54904 zip code has the fifth-highest property count (147) but one of the lowest ownership rates at just 2.3%. This indicates a large residential area that has attracted comparatively less investor interest.

Investors in Winnebago County are in a clear accumulation phase, consistently buying more properties than they sell. In Q1 2026, they demonstrated strong bullish sentiment by purchasing 68 properties while only selling 20, resulting in a net gain of 48 properties for the rental housing stock.

This activity translates to a buy-to-sell ratio of 3.4, indicating that for every single property an investor sold, another 3.4 were acquired. This signals strong confidence in the local rental market's future performance.

The pace of acquisitions has increased recently. The Q1 2026 ratio of 3.4 is a significant acceleration from the full-year 2025 ratio of 2.1 (225 buys vs. 107 sells) and the full-year 2024 ratio of 3.4 (361 buys vs. 105 sells).

The transaction data reinforces the negligible role of institutional capital in the market. In the entire year of 2025, the 1,000+ property tier recorded only one purchase and one sale, making them a non-factor in market dynamics.

This sustained net buying behavior, driven exclusively by small and mid-sized landlords, points to a long-term strategy of portfolio growth and a positive outlook on rental demand and property appreciation in Winnebago County.

In the first quarter of 2026, landlords participated in 68 of the 551 total SFR transactions, accounting for a 12.3% share of the market's transaction volume. All 68 of these transactions were purchases, with no sales recorded in this specific dataset for the quarter.

A striking pattern emerges in the pricing strategies across different investor tiers. Newcomers in the single-property tier paid the highest average price at $221,452 per property. This suggests they may be purchasing turn-key, on-market homes that command a premium.

In contrast, more experienced landlords appear to be securing properties at much lower prices. Investors in the 6-10 property tier paid an average of just $109,400, while those in the 21-50 property tier paid even less at $99,333. This price spread of over $122,000 between the highest and lowest tiers points to different acquisition strategies, with seasoned investors likely targeting value-add or distressed assets.

Mom-and-pop investors (Tiers 01-04) dominated the activity, conducting 55 of the 68 total transactions. As seen in other metrics, institutional investors made zero transactions, reinforcing their absence from the market.

Inter-landlord sales show a moderately liquid market for smaller portfolios. Landlords in the two-property tier sourced 50.0% of their acquisitions from other investors, while single-property landlords acquired 14.7% of their homes from existing landlords.
