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

In Brown County, landlords own 2,267 Single-Family Residential (SFR) properties, which constitutes a modest 2.9% of the total 79,059 SFRs in the market.

Individual investors are the primary drivers of the rental market, owning 1,724 properties or 76.0% of all investor-owned SFRs, compared to 571 properties (25.2%) held by companies.

A notable characteristic of this market is the high rate of co-ownership or partnerships, with 2,934 distinct landlord entities owning the 2,267 properties. This suggests that many investment properties are held by more than one individual or entity.

Cash is the preferred method of acquisition and holding, with 1,467 properties (64.7%) owned free and clear, while only 800 properties (35.3%) are financed. This indicates a financially stable and less leveraged investor base.

The portfolio is heavily focused on generating rental income, as demonstrated by the 2,027 properties identified as rented, representing 89.4% of all investor-owned homes in the county.

Investors in Brown County demonstrate a consistent ability to acquire properties at a significant discount compared to traditional homeowners. In Q4 2025, landlords paid an average of $282,996, which is 21.4% less than the $359,946 average paid by homeowners—a substantial monetary advantage of $76,950 per property.

This pricing advantage for investors intensified over the course of 2025. The discount widened from 11.0% ($40,882) in Q2 to a remarkable 23.5% ($90,030) in Q3, before settling at 21.4% in Q4, indicating increasingly favorable buying conditions for landlords.

Despite a year-over-year decrease from the average price of $341,143 in 2024, the Q4 2025 average price of $282,996 still represents a significant 14.1% appreciation over the pandemic-era (2020-2023) average of $248,119.

The quarterly data reveals a pattern of strategic acquisition, where landlords appear to capitalize on market opportunities to purchase well below the prevailing retail price point.

The consistent, double-digit discount across all quarters of 2025 underscores that landlords are not simply paying market price but are actively finding and negotiating deals that are unavailable or overlooked by typical homebuyers.

Landlord purchasing activity accounted for 6.0% of the total market in Q4 2025, with investors acquiring 52 of the 862 SFR properties sold in Brown County.

The market's growth is overwhelmingly fueled by small-scale investors. Mom-and-pop landlords (owning 1-10 properties) were responsible for 48 of the 52 investor purchases, a commanding 92.3% share of acquisition activity.

First-time or single-property investors were the most active segment, with 59 new entities acquiring 47 properties. This group alone made up 90.4% of all landlord purchases, signaling a robust influx of new participants into the local rental market.

In stark contrast to the active small landlord segment, institutional investors (1,000+ properties) had no purchasing activity in Brown County during Q4, highlighting their absence from this market.

The data shows a clear pattern of grassroots expansion, where the investor base grows through new, small-scale participants rather than through consolidation by large corporate entities.

The investor landscape in Brown County is definitively characterized by small-scale ownership. Mom-and-pop landlords, defined as those owning 1-10 properties, command a massive 94.3% of all investor-held SFRs.

The market's foundation is built upon single-property investors (Tier 01), who own 1,791 properties. This single tier accounts for 77.9% of all investor-owned housing, underscoring the hyper-local, decentralized nature of the rental market.

Mid-size landlords (11-1,000 properties) collectively own just 5.1% of the investor-held inventory, playing a minor role in the overall market structure.

Challenging the narrative of corporate dominance, institutional investors with portfolios of over 1,000 properties have a minimal presence, owning only 14 properties. This represents just 0.6% of the investor market, confirming their near-total absence from Brown County.

This distribution reveals a market with extremely low concentration at the top, where the vast majority of rental housing is provided by local, small-portfolio landlords rather than large corporations.

Ownership structure in Brown County shows a clear evolution as portfolios grow. Individual investors overwhelmingly dominate the entry-level tiers, owning 85.1% of single-property investments and 65.6% of portfolios with 3-5 properties.

The transition to corporate ownership occurs decisively at the 6-10 property tier. At this level, companies own 86.7% of the properties (65 units), while individuals own just 13.3% (10 units), marking it as the key crossover point for professionalization.

This pattern suggests that as local investors scale their operations beyond five properties, they are highly likely to incorporate for liability and financial management purposes.

Despite this trend, individual ownership persists even at larger scales within the county. In the 101-1,000 property tier, individuals still own 3 of the 7 properties (42.9%), demonstrating that significant portfolios can be managed without a corporate structure.

The data indicates two distinct investor paths: a large base of individuals managing small portfolios, and a smaller group of more professionalized operators who adopt a corporate structure as they scale.

Geographic analysis of investor activity within Brown County is concentrated in specific areas. The zip code 54115 emerges as a key hub, hosting 372 investor-owned SFR properties, the highest count among areas with available data.

In the 54115 area, the 372 investor-owned properties represent a 2.8% ownership rate, which is closely aligned with the overall county average of 2.9%. This suggests that while it has the highest volume, its investor penetration is typical for the region.

Data for several other prominent zip codes, including 54110, 54165, 54227, and 54230, was unavailable for this report. A complete picture of geographic concentration and high-penetration hotspots cannot be fully determined without this information.

The concentration in 54115 indicates a focal point for rental demand and investment opportunity, likely driven by local economic factors, school districts, or housing stock characteristics that are attractive to landlords.

While county-level investor presence is modest, the data points to specific sub-markets like 54115 where rental property ownership is more consolidated.

Landlords in Brown County are in a strong accumulation phase, consistently buying far more properties than they sell. In Q4 2025, they purchased 64 homes while selling only 5, resulting in an aggressive 12.8-to-1 buy/sell ratio.

This net-buyer behavior has gained momentum throughout the year. The ratio climbed from 8.2-to-1 in Q3 to 12.8-to-1 in Q4, indicating an increasing appetite for acquisitions as the year concluded.

Comparing annually, the net acquisition pace in 2025 (8.89x ratio with 329 buys vs. 37 sells) was significantly higher than in 2024 (5.24x ratio with 461 buys vs. 88 sells), signaling a strategic shift towards holding and expansion.

The data on institutional (1000+ tier) transactions was unavailable, but their absence in all other purchasing and ownership data strongly suggests they are not a factor in the county's transaction market.

This sustained and accelerating net-buying activity reveals strong confidence among local landlords in the future of the Brown County rental market, as they actively expand their portfolios rather than divest.

In Q4 2025, landlords were involved in 64 of the 1,329 total SFR transactions in Brown County, accounting for a 4.8% share of market activity.

A critical finding is the complete absence of inter-landlord trading. One hundred percent of investor purchases came from the non-landlord market, indicating investors are exclusively acquiring properties from traditional homeowners, not from each other. This points to a buy-and-hold strategy rather than speculative flipping among investors.

A stark pricing difference exists between investor tiers. New single-property investors paid the most, at an average of $293,526 per home. In contrast, more established medium-large landlords (51-100 properties) acquired assets at a much lower average price of $104,250.

This price gap suggests different acquisition strategies: new entrants are buying market-rate, move-in-ready homes, while larger operators are likely targeting distressed or value-add properties that require capital but are acquired at a deep discount.

Mom-and-pop investors (Tiers 01-04) dominated the transaction volume with 60 purchases, while institutional investors had no recorded transactions, reinforcing that the market's liquidity is driven entirely by small operators.
