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

In Columbia County, investors hold a significant 2,117 Single-Family Residential properties, accounting for 11.3% of the total 18,682 SFRs in the market.

The ownership structure is overwhelmingly dominated by individual investors, who own 1,720 properties, or 81.2% of the entire investor portfolio, compared to 416 properties (19.7%) owned by companies.

This individual dominance extends to the entity level, with 2,317 individual landlords far outnumbering the 399 company landlords, reinforcing the 'mom-and-pop' character of the local rental market.

A highly unusual characteristic of this market is the complete absence of financing; all 2,117 investor-owned properties are held in cash, suggesting low leverage and high equity among local investors.

The portfolio is clearly geared towards generating rental income, as evidenced by the 2,067 properties classified as rented, which represents 97.6% of all investor-owned homes.

In Q4 2025, landlords demonstrated sharp purchasing acumen, acquiring properties for an average of $325,600, which is 11.5% less than the $367,863 paid by traditional homeowners—a net discount of $42,263 per property.

This Q4 discount represents a significant market shift, completely reversing the trend seen in the first three quarters of 2025 where landlords consistently paid premiums. The volatility peaked in Q2, when landlords paid an average of $680,746, a $296,506 (77.2%) premium over homeowners.

The data reveals substantial price appreciation over time. The average landlord acquisition price has surged 68.2% from the 2020-2023 average of $290,297 to the 2025 average of $488,149.

The sharp quarterly fluctuations in landlord pricing, from a 77.2% premium to an 11.5% discount within months, suggest that a small number of non-standard or high-value transactions can heavily influence the quarterly averages in a smaller market like Columbia County.

Despite the lack of purchases in most recent quarters, the price data indicates that when landlords do buy, their pricing strategy relative to the homeowner market is highly variable and opportunistic.

Investor activity accounted for 15.6% of the housing market in Q4, with landlords purchasing 5 of the 32 total SFRs sold in Columbia County.

The entirety of this purchasing activity was driven by small investors, as mom-and-pop landlords (Tiers 01-04) made 100% of the investor acquisitions. Institutional investors with over 1,000 properties had no presence in the market.

New entrants are the lifeblood of the local investor market. Six new landlord entities purchased 4 single properties, representing 80.0% of all investor buying activity for the quarter.

The data shows a clear concentration at the smallest end of the investor spectrum, with no purchases made by any investor holding more than five properties.

This Q4 activity reinforces the market's structure as one built on a foundation of new and small-scale landlords rather than portfolio growth from larger, established players.

The investor landscape in Columbia County is overwhelmingly dominated by small-scale operators. Mom-and-pop landlords (owning 1-10 properties) control 99.9% of the 2,117 investor-owned SFRs.

Ownership is heavily concentrated in the smallest tier, with single-property landlords alone holding 1,790 properties, which constitutes a remarkable 83.2% of the entire investor-owned housing stock.

The next three tiers combined—those owning 2 to 10 properties—make up just 16.7% of the portfolio, further highlighting the market's reliance on first-time and very small investors.

There is a complete absence of large-scale and institutional investment, with zero properties held by landlords in the 1,000+ property tier. This signifies a highly fragmented market insulated from large corporate influence.

The data shows a market structure that is broad at the base but lacks any significant scale, with almost no investors growing their portfolios beyond 10 properties in the county.

Across all portfolio sizes in Columbia County, individual investors maintain majority control. Their ownership share remains robust from the single-property tier (81.5%) all the way to the 6-10 property tier (91.5%).

Unlike in more consolidated markets, there is no tier where company ownership surpasses individual ownership. This absence of a 'crossover point' indicates that even as portfolios grow modestly, they tend to remain under individual control.

Company ownership reaches its peak in the 3-5 property tier, where corporations hold 47 properties, or 28.8% of the homes in that segment.

Interestingly, the corporate share declines in the next tier up, falling to just 8.5% in the 6-10 property category. This suggests that the few companies operating in the market do not typically scale beyond a small handful of properties.

This pattern reinforces that the path to portfolio growth in Columbia County is predominantly an individual endeavor, not a corporate one.

A significant concentration of investor properties exists within just three zip codes. Together, 53901 (Portage), 53555 (Lodi), and 53955 (Poynette) are home to 1,189 investor-owned SFRs, representing 56.2% of the county's total investor portfolio.

The largest market by sheer volume is 53901, which contains 484 investor-owned homes, corresponding to a 12.0% ownership rate.

A key finding is the divergence between high-volume and high-penetration areas. The zip code 53571 stands out with a 100.0% investor ownership rate, indicating it is a small, fully investor-controlled area, though it does not top the list for property count.

Similarly, 53561 shows a very high concentration with a 35.8% investor ownership rate, well above the county average of 11.3%, signaling a prime target for rental investment.

This geographic analysis reveals distinct investor strategies: targeting larger population centers like Portage for volume, while also identifying smaller communities where they can achieve a much higher market share.

Landlords acted as strong net buyers throughout 2024, signaling confidence in the Columbia County real estate market. They purchased 70 properties while selling only 19, resulting in a buy-to-sell ratio of 3.68 to 1.

This aggressive acquisition strategy led to a net expansion of investor portfolios in the county by 51 SFR properties over the course of the year.

The high volume of buying compared to selling suggests that investors were focused on accumulation and long-term holds rather than short-term flipping or divestment during 2024.

No specific data is available for institutional (1,000+ unit) investors, but their overall absence from ownership statistics in the county implies their transaction volume was likely zero.

The transaction behavior from 2024 paints a picture of a growing, acquisitive investor base composed almost entirely of small-scale operators looking to expand their local holdings.

In the final quarter of 2025, landlords participated in 7 of the 47 total SFR transactions, capturing a 14.9% share of all market activity.

This activity was exclusively driven by mom-and-pop investors, who accounted for 100% of landlord-related transactions. Institutional investors logged zero transactions, reflecting their lack of presence in the county.

A notable finding is that investors sourced all new properties from the general market, with 0% of their purchases coming from other landlords. This indicates a focus on acquiring homes from traditional homeowners rather than trading within the investor community.

Pricing strategies appeared to differ by experience level. Investors in the 3-5 property tier paid an average of $403,200, a significant $90,533 more than the $312,667 average paid by new single-property landlords.

First-time or single-property investors were the most active group, responsible for 6 of the 7 (85.7%) landlord transactions, underscoring their role as the primary engine of investor market activity.
