Kendall (IL) Investor Pulse Report (2026-Q1)

In Kendall County, investors hold a significant 16.5% of the Single-Family Residential (SFR) market, totaling 6,816 properties out of 41,305. This demonstrates a substantial footprint for real estate investing in the local housing ecosystem.

The ownership structure is overwhelmingly dominated by 9,095 individual landlords who own 5,994 properties, or 87.9% of the investor-owned market. In contrast, 601 companies own just 963 properties, representing 14.1% of the portfolio, which challenges the narrative of corporate dominance in this area.

A striking 98.7% of investor-owned properties (6,726 out of 6,816) are classified as rented, confirming that the primary activity of these landlords is providing rental housing to the community. This high rental penetration underscores their role in the local housing supply.

Financing is the preferred method for portfolio building, with 69.6% of investor-owned properties (4,743) carrying a mortgage. Cash purchases account for the remaining 2,073 properties, suggesting that leverage is a key strategy for growth among Kendall County investors.

The data reveals a market comprised of many small players. With 9,696 distinct landlord entities owning 6,816 properties, the average portfolio size is very small, reinforcing the 'mom-and-pop' character of the local investor landscape.

In the first quarter of 2026, landlords demonstrated a distinct pricing advantage, acquiring properties for an average of $371,710. This was $27,676, or 6.9%, below the $399,386 average paid by traditional homeowners, showcasing a capacity to find and secure better deals.

However, this landlord discount is not a consistent market feature. The trend has been highly volatile, with investors paying a 7.1% premium ($28,370) in Q3 2025 and a 5.2% premium ($18,743) in Q1 2025. This variability suggests investors adapt their pricing strategies based on changing market conditions and inventory levels.

Acquisition prices have appreciated significantly since the 2020-2023 period, when the average landlord purchase price was $351,936. The Q1 2026 average of $371,710 reflects a notable increase in property values over the past few years.

Comparing prices across years reveals steady growth. The average landlord acquisition price rose from $403,580 in 2024 to $407,324 in 2025, a modest but clear upward trend in asset values within investor portfolios.

The fluctuating gap between landlord and homeowner prices indicates a dynamic market where investors are not simply passive, low-price buyers. At times, they are willing to outbid homeowners for strategic acquisitions, as seen in multiple quarters of 2025.

Investor purchasing was exceptionally strong in Q4, with landlords acquiring 180 out of 270 total SFRs sold in Kendall County. This represents a commanding 66.7% of all market transactions, signaling a period of aggressive portfolio expansion.

The acquisition activity was almost entirely driven by small investors. Mom-and-pop landlords (Tiers 01-04) purchased 174 properties, making up 96.1% of the investor total and underscoring their role as the primary source of demand in the market.

New entrants flooded the market, with 226 new single-property landlord entities acquiring 164 homes. This tier alone constituted 90.6% of all investor purchases, highlighting a robust pipeline of new individuals beginning their investment journeys.

In stark contrast, institutional-level activity was negligible. The 1000+ property tier investors purchased just one property during the entire quarter, representing only 0.6% of investor acquisitions. This minimal presence dispels any notion of large-scale corporate buying in this market.

Mid-size landlords (11-1000 properties) also showed limited buying activity, collectively purchasing only 7 properties. The data clearly shows that Q4's high investor market share was a result of broad activity from small-scale players, not concentrated buying from large firms.

The investor market in Kendall County is fundamentally a small-scale operation. Landlords with portfolios of 1-10 properties (Tiers 01-04) collectively own 6,563 SFRs, which amounts to a staggering 94.4% of the entire investor-owned housing supply.

Dispelling common narratives of institutional dominance, investors in the 1,000+ property tier own a mere 234 homes. This represents just 3.4% of the investor-owned market, a fractional share compared to the vast holdings of smaller landlords.

The single-property landlord (Tier 01) is the most significant segment, with 5,875 properties representing 84.5% of all investor holdings. This highlights that the typical investor journey in this market begins and often stays at a very small scale.

The distribution of ownership is heavily skewed towards the smallest tiers. After the single-property tier, ownership drops sharply to 3.9% for two-property landlords and 4.9% for those owning 3-5 properties, reinforcing the fragmented nature of the market.

The combined share of all mid-to-large investors (11 to 1000+ properties) is only 5.6%. This structure suggests a highly decentralized rental market, resilient against the actions of any single large entity and primarily shaped by local, individual decision-makers.

Individual investors form the backbone of the Kendall County rental market, especially in smaller portfolio tiers. They own 93.1% of all single-property investor homes (5,575 properties) and 73.5% of two-property portfolios (200 properties).

A distinct crossover point occurs as investors scale their operations. While individuals maintain a majority in the 6-10 property tier (56.8%), companies become the dominant entity type in the 21-50 property tier, owning 14 out of 17 properties (82.4%).

This pattern suggests a natural business progression where investors incorporate as their portfolios grow larger and more complex. The near-even split in the 11-20 property tier (54.4% individual vs. 45.6% company) appears to be the transition zone for this structural shift.

Even at smaller scales, company ownership is present, accounting for 28.2% of properties in the 3-5 home tier. This indicates that some investors choose to incorporate early in their journey for liability or financial reasons.

The data clearly shows two different investor profiles: the typical individual who owns 1-5 properties and the more professionalized operator who uses a company structure to manage portfolios exceeding 10-20 properties. Understanding this distinction is key to analyzing market behavior.

Geographically, investor activity in Kendall County is heavily concentrated in two zip codes: 60560 (Yorkville) with 1,802 investor-owned properties and 60543 (Oswego) with 1,742. Together, these two areas account for over half of all investor-owned SFRs in the county.

The highest counts do not necessarily correlate with the highest market penetration. While 60560 has the most investor properties, its ownership rate is 19.1%. In contrast, the much smaller 60536 (Lisbon) boasts a 60.0% investor ownership rate, making it the most saturated market by percentage.

Several smaller zip codes exhibit extremely high concentrations of rental properties. Following Lisbon, 60511 (Bristol) has a 50.0% rate, 60554 (Sandwich) has a 44.4% rate, and 60537 (Millbrook) has a 43.5% rate. This pattern points to targeted investment strategies in specific micro-markets.

The top five zip codes by sheer volume of investor properties are 60560 (Yorkville), 60543 (Oswego), 60538 (Montgomery), 60545 (Plano), and 60431 (Joliet). These areas represent the core of large-scale rental portfolio development in the county.

The divergence between leadership in count versus percentage reveals different investor approaches. Some investors may target larger, more liquid markets like Yorkville and Oswego for scale, while others focus on smaller communities to achieve higher market control and saturation.

Landlords in Kendall County are in a phase of strong portfolio growth, acting as decisive net buyers. In Q1 2026, they acquired 250 properties while selling only 26, resulting in a net gain of 224 properties and a buy-to-sell ratio of 9.6 to 1.

This net buying behavior is a consistent, multi-year trend. In 2025, investors bought 1,855 SFRs and sold 197 (a 9.4x ratio), and in 2024, they bought 2,169 and sold 215 (a 10.1x ratio). This sustained accumulation signals strong confidence in the local market.

Institutional investors (1000+ tier) are moving in the opposite direction. They were net sellers in Q1 2026, with 1 purchase and 2 sales. This follows their trend from 2025, where they purchased only 1 property but sold 5, indicating a strategy of divestment or portfolio rebalancing in this specific county.

The divergence is stark: while the broad market of smaller, local investors is actively expanding its footprint, the largest national players are reducing their exposure in Kendall County. This highlights a fundamental difference in strategy and market outlook between the two groups.

The high volume of acquisitions compared to dispositions suggests that the majority of investors are focused on long-term holds rather than short-term flips. The consistent net accumulation of properties points to a market driven by buy-and-hold strategies aimed at generating rental income.

In Q1, landlords were the dominant force in the Kendall County real estate market, participating in 250 of the 382 total SFR transactions. This 65.4% share of activity underscores their critical role in providing market liquidity and setting price floors.

A clear pricing disparity exists between investor tiers. The single institutional purchase in Q1 was at $490,000, which is 28.1% higher than the $382,646 average paid by the 226 new, single-property landlords. This suggests larger players may target higher-value assets or pay a premium for specific properties.

Mom-and-pop investors (Tiers 01-04) accounted for the overwhelming majority of transactions, with 240 purchases. This compares to just one purchase by an institutional investor, confirming that market activity is driven from the bottom up.

Inter-landlord trading activity is relatively low, particularly among new investors. Only 7.1% of properties bought by single-property landlords came from other investors. This indicates that the vast majority of acquisitions are new additions to the overall rental stock, rather than properties churning between existing investors.

The smallest investors are not necessarily getting the best price. The single transaction in the 6-10 property tier was for just $88,000, while medium-sized investors also purchased properties below the Tier 01 average, showing a wide range of pricing strategies across different sub-markets and property types.
