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

Investor-owned properties comprise a significant 16.2% share of the single-family residential market in Monroe County, totaling 2,300 homes.

Individual investors form the backbone of the rental market, owning 1,550 properties (67.4%), more than double the 755 properties (32.8%) held by companies.

The ownership structure is similarly skewed towards individuals, with 1,812 individual landlords compared to just 448 company landlords, a ratio of over 4 to 1.

A striking 90.4% of the investor portfolio (2,080 properties) is owned outright in cash, indicating a market of well-capitalized investors rather than highly leveraged players.

The portfolio is almost entirely dedicated to rentals, with 2,230 of the 2,300 properties (97.0%) being rented, confirming a strong focus on generating rental income within the local market.

Landlords in Monroe County secured properties for an average of $251,172 in Q4 2025, representing a 1.9% discount compared to the $256,167 paid by traditional homeowners.

The price advantage for landlords fluctuates dramatically, shrinking to just $4,995 in Q4 from a substantial $99,120 (29.2%) discount in Q3 2025, suggesting inconsistent negotiating power or market conditions.

The average landlord acquisition price has seen substantial growth, rising from a 2020-2023 average of $165,540 to an average of $243,999 for the full year 2025.

Compared to the previous year, landlord acquisition prices in 2025 ($243,999) are 15.8% higher than in 2024 ($210,669), indicating strong market appreciation.

Throughout 2025, the landlord discount has been inconsistent, ranging from a low of 1.9% in Q4 to a high of 29.2% in Q3, making it difficult to predict their purchasing advantage from one quarter to the next.

Investor activity accounted for over a quarter of the market in Q4 2025, with landlords purchasing 17 of the 62 total SFRs sold.

The market is being shaped by new and small investors, as 21 new single-property entities entered the market, acquiring 14 properties (82.4% of all landlord purchases).

Mom-and-pop landlords (Tiers 01-04) were responsible for 15 of the 17 investor purchases, a dominating 88.2% share of acquisition activity.

There was a complete absence of institutional buying activity in Q4, with the 1000+ property tier recording zero purchases.

The only other active tier was the small-medium category (21-50 properties), where a single entity acquired 2 properties, representing 11.8% of the quarter's investor activity.

The investor landscape in Monroe County is defined by small-scale ownership, with mom-and-pop landlords (1-10 properties) holding 88.4% of the entire investor-owned SFR portfolio.

Single-property landlords are the most significant group, owning 1,477 properties, which accounts for 62.4% of all investor-owned homes.

Mid-size landlords (11-100 properties) control a combined 11.6% of the portfolio, showcasing a small but established segment of professional investors.

The narrative of large-scale institutional ownership does not apply here, as the 1000+ property tier holds only one property, making up a statistically insignificant 0.0% of the market.

The market structure is highly fragmented, with the top four 'mom-and-pop' tiers containing the vast majority of assets, indicating a low barrier to entry for new investors.

Individual investors dominate the entry-level tiers, owning 81.5% of single-property portfolios and 58.6% of two-property portfolios.

A clear shift to corporate ownership occurs as portfolio sizes increase. The crossover point is the '6-10 properties' tier, where companies own a 68.7% majority share.

Even in the '3-5 properties' tier, individuals maintain a strong 65.4% majority, showing that personal ownership remains the preferred structure for smaller-scale landlords.

The largest non-institutional tier in the data, '11-20 properties,' shows a more balanced but still company-led split, with corporations owning 72 properties (59.0%) compared to individuals' 50 (41.0%).

This data reveals a distinct lifecycle: investors enter the market as individuals and tend to incorporate as their portfolios grow beyond five properties, likely for liability and operational efficiency.

The zip codes for Sparta (54656) and Tomah (54660) are the epicenters of investor ownership by volume, containing 801 and 738 investor-owned properties, respectively.

High investor concentration is not limited to the largest towns. Warrens (54666) has the highest ownership rate at 32.3%, indicating a significant rental market presence in a smaller community.

Several other smaller communities exhibit high investor penetration, including Norwalk (54651) at 30.9% and Cashton (54615) at 24.1%.

The data highlights a key difference between raw volume and market saturation. While Sparta has the most investor properties, Warrens has the highest proportion of them, suggesting different market dynamics.

The top five zip codes by ownership rate are all above 24%, showing that investor focus is not confined to a single area but is spread across several key communities in Monroe County.

Investors are consistently in accumulation mode, demonstrated by a strong net positive acquisition of 82 properties in 2025 (86 buys vs. 4 sells).

This pattern of aggressive buying is not new; in 2024, landlords were also significant net buyers, adding a net 113 properties to their portfolios (139 buys vs. 26 sells).

The minimal selling activity, especially in 2025 with only 4 properties sold, suggests a long-term hold strategy is prevalent among landlords in the county.

Even the market's sole institutional-tier investor is in a growth phase, albeit a small one, having been a net buyer of one property in 2024.

The consistent, high-volume net purchasing across the last two years indicates strong confidence in the Monroe County rental market from its investor base.

Investors were a major force in the Q4 2025 market, participating in 25 of the 92 total transactions, a 27.2% share.

New entrants are paying competitive prices. Single-property landlords (Tier 01) paid an average of $257,186, not far from the $279,200 average for small-medium investors (Tier 21-50), suggesting they are not solely focused on deep-discount properties.

The market for investor acquisitions is sourced entirely from the traditional market, as 0% of the 25 landlord transactions involved purchasing from another landlord.

Mom-and-pop landlords dominated the transaction volume, with their tiers accounting for 23 of the 25 total investor transactions.

There were no institutional transactions in Q4, reinforcing that the quarter's activity was exclusively driven by smaller to mid-sized players expanding their portfolios from the homeowner market.
