Hamilton (IL) Investor Pulse Report (2025-Q4)

In Hamilton County, IL, investors hold a portfolio of 333 Single-Family Residential (SFR) properties, making up 17.6% of the total SFR market of 1,897 homes.

The ownership structure is heavily skewed towards individuals, with 350 individual landlords controlling 281 properties (84.4% of the investor-owned market). This contrasts sharply with the 47 company landlords who own the remaining 56 properties (16.8%).

This individual dominance highlights a market driven by small-scale, local investment rather than large corporate entities.

Financial strategies among these investors strongly favor outright ownership, with 287 properties held in cash compared to only 46 that are financed. This suggests a low-leverage, risk-averse approach is prevalent in the county.

The portfolio is clearly geared towards rental income, as 324 of the 333 properties are non-owner-occupied, a rental penetration rate of 97.3%.

Investors in Hamilton County demonstrated a powerful purchasing advantage in Q4 2025, acquiring properties for an average of $50,000. This was a staggering 47.8% less than the $95,833 paid by traditional homeowners, representing a raw discount of $45,833 per property.

This pricing gap has not been consistent throughout the year, showcasing investors' ability to capitalize on changing market conditions. The Q4 discount of 47.8% is significantly larger than the 18.8% discount seen in Q3 and the 12.3% discount in Q2.

The long-term price trend reveals significant market appreciation. The average investor purchase price for 2025 stood at $84,914, a dramatic increase from the average of $38,900 during the 2020-2023 period.

While no properties were officially recorded as purchased in Q4 under the 'Landlord Acquisitions by Timeframe' data, the 'Landlord vs Homeowner Comparison' data confirms pricing for the quarter, indicating active participation at these discounted levels.

This pricing behavior suggests landlords in the area are adept at identifying undervalued assets or negotiating favorable terms, a key strategic advantage over typical homebuyers.

Investor activity accounted for a significant portion of the market in Q4 2025, with landlords acquiring 5 of the 20 total SFR properties sold, a market share of 25.0%.

The entirety of this purchasing activity came from small-scale investors. Mom-and-pop landlords (Tiers 01-04) made up 100.0% of all landlord acquisitions, demonstrating that the market's growth is driven from the ground up.

In contrast, institutional investors (Tier 09) were completely inactive, making zero purchases in the quarter.

The market continues to attract new participants, with 2 new single-property landlords entering in Q4, who collectively purchased 1 property.

The most active buyers were in the small landlord (3-5 properties) tier, with a single entity acquiring 3 properties, representing 60.0% of all investor purchases for the quarter.

The investor landscape in Hamilton County is unequivocally dominated by small-scale mom-and-pop landlords (1-10 properties), who collectively own 98.8% of all investor-held SFRs.

This concentration is most pronounced at the smallest end of the spectrum. Single-property landlords (Tier 01) are the backbone of the market, owning 274 properties, which constitutes a remarkable 80.4% of the entire investor portfolio.

The presence of large-scale investors is negligible. Institutional firms (Tier 09, 1000+ properties) own just a single property, accounting for only 0.3% of the market and underscoring their lack of focus on the county.

Mid-size landlords (11-1000 properties) also have a minimal footprint, with only the 101-1000 property tier being represented by 3 properties (0.9% share).

This distribution reveals a highly fragmented market, characterized by a large number of very small investors rather than a consolidation of ownership under a few large players.

In Hamilton County, individual investors maintain majority control across every active small-ownership tier, preventing any crossover where companies become dominant.

In the foundational single-property tier, individuals hold a commanding 88.4% share (245 properties), compared to just 11.6% for companies (32 properties).

Even as portfolios grow, individuals retain their lead. In the two-property tier, individuals own 23 properties (67.6%), while companies hold 11 (32.4%).

Companies achieve their peak market penetration in the two-property tier at 32.4%, but this share diminishes in the next tier up (3-5 properties), where their ownership drops to 25.9%.

This pattern shows that the path to portfolio growth in this county is primarily paved by individual efforts, with corporate structures playing a secondary, supporting role rather than a leading one.

Investor ownership in Hamilton County is highly concentrated geographically, with the 62859 zip code serving as the clear hub, containing 236 landlord-owned SFRs.

Following at a distance are 62828 with 53 properties and 62817 with 30 properties. Together, these top three zip codes account for 319 properties, or 95.8% of the entire investor portfolio in the county.

An analysis of ownership rates reveals a different leader. The 62817 zip code has the highest investor penetration, where 25.2% of all SFRs are investor-owned, indicating a strong rental market focus in that specific area.

Other areas with high investor saturation include 62860 (25.0%) and 62895 (20.0%), even though their total property counts are lower.

This distinction between high-volume and high-percentage areas highlights different pockets of investor strategy within the same county market.

A notable shift in investor behavior occurred in Q4 2025, as landlords became net sellers for the first time in the year, selling 7 properties while purchasing only 6.

This recent cooling of acquisition appetite is a stark reversal from the prior quarter. In Q3 2025, investors were aggressive net buyers, acquiring 14 properties and selling only 3, a net gain of 11 properties.

Despite the end-of-year slowdown, the overall trend for 2025 shows landlords expanding their portfolios. Cumulatively, they have purchased 30 properties while only selling 12, making them significant net buyers for the year.

This pattern is consistent with the previous year, as 2024 also saw strong net buying activity with 18 purchases against just 3 sales.

Institutional investors (1000+ tier) recorded no transactions throughout these periods, reinforcing that all market dynamics are driven by smaller, independent landlords.

In Q4 2025, landlords were a key component of market liquidity, participating in 6 of the 28 total SFR transactions, a share of 21.4%.

All of this activity was driven by mom-and-pop investors, as institutional-grade landlords made no transactions. The activity was spread across the smallest tiers, with 2 transactions by single-property investors, 1 by two-property investors, and 3 by small landlords (3-5 properties).

A significant pattern of inter-landlord trading emerged. Both the two-property and small landlord (3-5) tiers sourced 100% of their acquisitions from other landlords, suggesting a mature market where existing rental properties are changing hands between investors.

Purchase prices varied by tier, with small landlords (3-5 properties) paying the highest average price at $70,000.

In contrast, single-property landlords entering the market or expanding their first holding paid an average of $35,000 and did not source their purchases from existing landlords.
