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

In Grundy County, the investor footprint is modest, with landlords owning 149 single-family residential properties, which constitutes just 1.0% of the 14,986 total SFRs in the market.

The market is characterized by small-scale ownership, as individual investors own 132 of these properties, making up 88.6% of the investor-owned housing stock. In contrast, company-owned properties number only 19, or 12.8% of the total.

This individual dominance is also reflected in the landlord entity count, where 174 of the 189 total landlords (92.1%) are individuals, reinforcing the 'mom-and-pop' nature of the local rental market.

A significant majority of the investor portfolio, 127 properties (85.2%), are non-owner-occupied, indicating a strong focus on rental income generation.

Investors in the area appear to rely heavily on leverage, with 100 properties (67.1%) being financed, while 49 properties (32.9%) were acquired with cash.

In a striking reversal of typical market dynamics, landlords in Grundy County paid more than traditional homeowners in Q4 2025, with an average acquisition price of $346,000 compared to the homeowner average of $340,105. This resulted in a $5,895 premium, or 1.7% above the homeowner price.

This Q4 premium represents a significant departure from the trend observed earlier in the year. In Q3, landlords secured a 16.4% discount ($56,867), and in Q2, they achieved an even larger 22.6% discount ($80,914), highlighting a potential tightening of the market for investors toward year-end.

The price appreciation in the market is substantial when comparing recent activity to the pandemic era. The Q4 2025 average landlord price of $346,000 is 50.2% higher than the average of $230,315 recorded between 2020 and 2023.

Annually, landlord purchase prices have remained relatively stable, with a slight decrease from a $276,202 average in 2024 to a $275,438 average for 2025 overall, despite the quarterly fluctuations.

Investor purchasing activity in Grundy County was limited in the fourth quarter, with landlords acquiring 5 of the 128 total SFR properties sold, capturing a 3.9% market share.

The market's new investor activity is fueled exclusively by small operators. Mom-and-pop landlords (Tiers 01-04) were responsible for 60.0% of all landlord purchases, acquiring 3 properties.

Two new landlords entered the market in Q4, each purchasing their first investment property. These single-property investors alone accounted for 40.0% of all landlord acquisitions during the period.

Mid-size and larger landlords showed minimal activity, with one property purchased by an investor in the 21-50 property tier and one by an investor in the 101-1000 property tier.

Institutional investors with portfolios of over 1,000 properties were entirely absent from the purchasing market in Q4, making zero acquisitions and ceding all activity to smaller players.

The investor landscape in Grundy County is overwhelmingly dominated by small-scale landlords. Mom-and-pop investors (owning 1-10 properties) control 94.0% of all investor-owned single-family homes, cementing their status as the foundation of the local rental market.

Single-property landlords (Tier 01) represent the largest single segment by a wide margin, owning 120 properties. This accounts for 79.5% of all investor-held SFRs, indicating that the market is heavily composed of first-time or small-scale investors.

Conversely, the presence of institutional investors (Tier 09, 1000+ properties) is negligible. This group owns just 2 properties in the county, making up only 1.3% of the investor portfolio and challenging any narrative of large-scale corporate ownership.

Mid-size investors (11-1000 properties) hold the remaining portion of the market, with Tiers 05 through 08 combined owning a total of 7 properties, or 4.6% of the investor-owned stock.

The data reveals a clear market structure where ownership is highly fragmented and concentrated at the smallest end of the investor spectrum, with very little influence from large portfolio holders.

Individual investors form the bedrock of the Grundy County rental market, particularly at the entry level. They own 118 of the 120 single-property portfolios, a commanding 97.5% share that highlights their role in driving grassroots real estate investment.

This pattern of individual dominance continues as portfolios grow slightly larger. Individuals own 100% of two-property portfolios and still represent a 77.8% majority in the 3-5 property tier, owning 14 of the 17 properties in that category.

Companies have a very limited presence in smaller portfolios. They own just 3 single-property portfolios (2.5%) and 4 portfolios in the 3-5 property range (22.2%).

The available data does not show a crossover point where companies become the majority owners. In all reported tiers, individual landlords hold the dominant share of properties, reinforcing the market's 'mom-and-pop' character.

This ownership structure suggests that the path to becoming a landlord in Grundy County is primarily pursued by private individuals rather than corporate entities, especially for those starting or managing small portfolios.

Investor property ownership in Grundy County is geographically concentrated, with the top three zip codes by count holding a significant portion of the portfolio. The zip code 60450 leads with 55 investor-owned properties, followed by 60447 (26 properties) and 60416 (25 properties).

A key finding is the divergence between areas with high property counts and those with high investor penetration rates. For instance, 60450, the leader in sheer volume, has a modest investor ownership rate of just 0.9%.

The areas with the highest saturation of investor ownership are different. The zip code 60420 has the highest rate at 3.8%, followed by 60474 (2.4%) and 60444 (2.3%). This indicates that investors have a stronger proportional presence in smaller, distinct pockets of the county.

This distinction reveals different market dynamics at play. Some zip codes attract a higher number of investors overall, while others represent niche markets where investors control a larger percentage of a smaller housing stock.

After a period of accumulation, landlords in Grundy County shifted to a neutral market position in the latter half of 2025. In Q4, they sold exactly as many properties as they bought (5), showing a significant slowdown in portfolio growth compared to earlier in the year.

This recent balance contrasts with the activity for the full year of 2025, where landlords were net buyers, acquiring 36 properties while selling 26 for a net gain of 10 properties. The trend was even stronger in 2024, with 75 buys versus 30 sells, resulting in a net gain of 45 properties.

The transaction data for institutional investors (1000+ tier) reveals a clear divestment strategy. In 2024, this group was a net seller, acquiring only 1 property while selling 5, for a net loss of 4 properties from their portfolio.

The cooling of acquisition activity among the broader landlord base, combined with active selling from institutional players, suggests a market that is maturing or stabilizing after a period of aggressive expansion.

In Q4 2025, landlord transactions represented a small fraction of overall market activity. With 5 transactions out of a total of 188, landlords accounted for 2.7% of the transaction volume in Grundy County.

A distinct pricing pattern emerged among tiers, where the smallest investors paid the highest prices. Single-property landlords (Tier 01) paid an average of $435,000 for their 2 acquisitions.

This is significantly higher than prices paid by larger, more experienced investors. For example, an investor in the 6-10 property tier paid $302,000, and one in the 101-1000 property tier paid just $212,000, revealing a potential experience-based discount.

There was no inter-landlord trading activity during the quarter. One hundred percent of the 5 properties purchased by investors were acquired from traditional homeowners or other non-investor entities, suggesting landlords are expanding their portfolios from the general housing supply rather than trading existing rental stock.

The purchasing activity was dominated by mom-and-pop investors, who were responsible for 3 of the 5 transactions, while institutional investors made no transactions in Q4.
