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

Investors hold a significant 11.9% share of the single-family residential market in Will County, IL, with a total portfolio of 25,257 properties.

The investor landscape is dominated by private individuals rather than corporations. Individual landlords own 19,757 properties, accounting for 78.2% of the investor-owned housing stock, while companies own the remaining 5,939 properties (23.5%).

This individual dominance is even more pronounced when looking at the number of entities, where 26,917 individual landlords far outnumber the 3,169 company landlords, a ratio of nearly 8.5 to 1.

The portfolio is heavily geared towards generating rental income, with 24,740 properties (97.9%) classified as rented or non-owner-occupied, confirming the business focus of these holdings.

Leverage is a key strategy for investors in the area, as 56.7% of the portfolio (14,319 properties) is financed, while 43.3% (10,938 properties) is owned free and clear.

On average, company landlords manage larger portfolios, holding approximately 1.9 properties per entity, compared to the roughly 0.7 properties per individual entity, which reflects co-ownership and a focus on smaller holdings among individuals.

In Q4 2025, investors demonstrated a distinct pricing advantage, acquiring properties for an average of $385,887, which is 3.6% less than the $400,314 paid by traditional homeowners—a savings of $14,427 per home.

This investor discount has been inconsistent, suggesting opportunistic buying rather than a permanent structural advantage. The Q4 discount marks a reversal from Q3 2025, when landlords paid a 2.2% premium ($9,014 more than homeowners), and from Q1 2025's 1.3% premium.

The market has seen substantial price appreciation since the pandemic era. The average Q4 2025 landlord purchase price of $385,887 represents a 66.3% increase over the average price of $231,999 recorded between 2020 and 2023.

While landlords secured a discount in the most recent quarter, the narrow 0.4% discount in Q2 2025 highlights the fluctuating nature of their purchasing power relative to the broader market.

The overall price trend for landlords in 2025 shows a slight cooling from Q2 highs, with the average acquisition price dropping from $420,486 in Q2 to $385,887 in Q4.

Landlord activity surged in Q4 2025, with investors acquiring 1,134 of the 1,708 total SFRs sold, capturing a dominant 66.4% share of the market.

The market was overwhelmingly fueled by small investors. Mom-and-pop landlords (those with 1-10 properties) were responsible for 1,112 of these purchases, making up 97.4% of all landlord acquisition activity.

A massive wave of new entrants joined the market, as 1,560 new single-property landlords acquired 1,021 homes, accounting for 89.4% of all properties bought by investors this quarter.

Institutional investors with portfolios over 1,000 properties had a negligible presence, purchasing only 3 properties, or 0.3% of the landlord total, highlighting their lack of activity in the Will County market.

The data reveals a highly fragmented acquisition landscape, where the overwhelming majority of buying is conducted not by large corporations, but by individuals and small businesses entering or expanding their presence in the rental market.

The investor-owned housing market in Will County is overwhelmingly controlled by small-scale operators. Landlords with 1-10 properties (Tiers 01-04) own a combined 89.9% of the entire investor SFR portfolio.

Single-property landlords form the bedrock of the market, alone accounting for 19,198 properties, or 74.1% of all investor holdings. This demonstrates that the typical landlord is not a large corporation but an individual with a single rental home.

Despite common narratives, the influence of institutional investors is minimal. The largest players (Tier 09, 1,000+ properties) own just 1,070 homes, representing only 4.1% of the total investor-owned supply.

Mid-size investors (11-1,000 properties) represent a small fraction of the market, collectively owning just 6.0% of properties, highlighting a significant gap between small mom-and-pop landlords and large institutions.

A clear pricing disparity exists across tiers. Q4 transaction data shows single-property buyers paid an average of $396,503, while institutional investors paid $270,667—securing a 31.7% discount, likely due to scale and ability to purchase off-market or distressed assets.

A distinct crossover point exists where ownership strategy shifts from individual to corporate structure. While individuals dominate smaller portfolios, companies become the majority owners (70.7%) in the 11-20 property tier.

The smallest portfolios are almost exclusively held by individuals. They own 88.6% of all single-property landlord portfolios and 73.6% of two-property portfolios, underscoring the grassroots nature of the market's entry point.

The 6-10 property tier acts as a transition zone. Here, ownership is nearly evenly split, with individuals holding a slight majority at 50.9% compared to companies at 49.1%, marking the pivot toward professionalization.

Beyond 20 properties, corporate ownership is nearly absolute. In the 21-50 property tier, companies own 95.1% of the homes, indicating that scaling a rental portfolio is strongly correlated with incorporation for liability and operational purposes.

This pattern reveals a clear lifecycle for real estate investors in Will County: starting as individuals and incorporating as their portfolios expand to a more professional scale.

Geographic analysis reveals heavy concentration of investor ownership by volume in specific areas, with the top five zip codes by count holding 8,299 properties, which is 32.8% of all investor-owned SFRs in Will County.

The 60435 zip code is the epicenter of investor holdings by sheer volume, containing 2,299 investor-owned properties, significantly more than any other area.

The metric for market penetration tells a different story. The highest density of investors is found in the 60543 zip code, where an astonishing 46.2% of all single-family residences are investor-owned.

A critical hotspot for both volume and density is the 60436 zip code. It ranks fourth for total investor properties (1,391) while also having the second-highest ownership rate at 27.0%, making it a core target for real estate investment.

This divergence between volume and penetration leaders suggests varied investor strategies. Some zip codes attract a high number of investors in a large housing market, while others represent smaller markets with extremely high saturation levels.

The transaction data reveals a fundamental split in market direction between small and large investors. Landlords as a whole are aggressively accumulating properties, while the largest institutional players are actively divesting their holdings in Will County.

In Q4 2025, the broader landlord market demonstrated a strong appetite for growth, purchasing 1,702 homes while selling only 221—a net gain of 1,481 properties and a buy-to-sell ratio of 7.7x.

This net-buyer trend has been consistent and robust throughout the year, with landlords recording a net gain of 7,040 properties in 2025, nearly mirroring the 7,553 net properties acquired in 2024.

Conversely, institutional investors (1,000+ portfolio) are in a sustained retreat. In Q4, they bought only 3 properties but sold 14, resulting in a net loss of 11 properties. This continues a multi-year trend of selling off assets.

The institutional divestment has accelerated. In 2025, they sold a net 67 properties, a significant increase from the net 50 properties they sold in 2024, signaling a strategic withdrawal from the region.

Investors were the primary driver of market activity in Q4 2025, taking part in 1,702 of the 2,625 total transactions, which translates to a commanding 64.8% share of all SFR sales and purchases.

The overwhelming majority of this activity came from the smallest players. Single-property landlords alone accounted for 1,562 transactions, while institutional investors were involved in only 3.

A stark pricing divide separates large and small investors. In Q4, single-property landlords paid an average of $396,503, a price point likely competitive with traditional homeowners. In contrast, institutional investors acquired properties for just $270,667 on average, a 31.7% discount.

Sourcing strategies also differ by investor size. The largest institutional investors relied on the existing landlord network for deals, acquiring 33.3% of their properties from other landlords.

New, smaller investors primarily bought from the open market, with only 10.6% of their purchases coming from other landlords. This suggests they are competing directly with homeowners rather than participating in a specialized investor-to-investor marketplace.
