Union County, IL: Top 20% of Agents Drive 67.8% of $11.6M Sales Volume
In Union County, Illinois, the real estate agent landscape demonstrates significant concentration, with a small percentage of top-performing agents controlling the vast majority of sales activity. During the trailing 12 months ending July 2026, the most active agents in the county commanded a dominant share of the market's total sales volume and homes sold, signaling a competitive environment for other real estate professionals and a clear hierarchy for investors to navigate.
County Overview
The residential real estate market in Union County, Illinois, recorded a total sales volume of $11.6M over the trailing 12 months, encompassing 70 homes sold. This modest market size highlights the impact of agent concentration, where a select group of agents effectively manages a substantial portion of transactions. According to BatchData's Top Agents Report, the top 20% of agents in Union County were responsible for a significant 67.8% of the total sales volume, indicating that more than two-thirds of the county's real estate value was transacted through a relatively small segment of its agent population. This level of concentration suggests that establishing a strong foothold in the market can be challenging for new or less-established agents.
The dominance extends even further up the ranks, with the top 1% of agents alone controlling 24.2% of the sales volume. This figure underscores the strong influence a handful of elite professionals wield in Union County's real estate market. For real estate investors, understanding this concentration is crucial for identifying key players who consistently close deals and for recognizing potential challenges in sourcing off-market properties or navigating competitive bidding environments. These top-tier agents likely have extensive networks and deep local market knowledge, making them valuable contacts but also formidable competitors.
When examining the number of homes sold, the pattern of concentration remains evident. The top 20% of agents were responsible for a substantial portion of the 70 homes sold in Union County, further reinforcing their market dominance. This suggests that these agents are not only handling high-value properties but also a significant volume of transactions overall. For those involved in real estate investing, particularly those focused on acquiring multiple properties, engaging with or monitoring the activity of these top agents could be a strategic advantage. Conversely, agents aspiring to increase their market share face stiff competition from these established leaders.
Local Market Context
Union County's real estate market, with its $11.6M in total sales volume, represents a niche segment within the broader Illinois state market. The county ranks #54 out of 102 counties in Illinois for agent sales concentration and contributes a mere 0.1% to the state's total sales volume, which stood at $22.8B during the same period. Nationally, the entire U.S. real estate market recorded $734.1B in sales volume, further contextualizing Union County's relatively small scale. Despite its modest size, the high agent concentration observed in Union County is a noteworthy structural characteristic that sets it apart from larger, potentially more fragmented markets.
The robust market share held by the top 20% of agents in Union County at 67.8% indicates a local landscape where expertise and established relationships are paramount. This figure suggests that while Union County's market size is small compared to the state or national totals, its internal dynamics are highly organized around a core group of successful agents. This structural characteristic means that investors looking to enter or expand within Union County will find a relatively transparent landscape in terms of who is driving transactions. Accessing property data and leveraging insights from market reports like this one can help identify these influential agents and understand their activity.
For agents, the concentration in Union County presents both a challenge and an opportunity. Breaking into the top tiers requires significant effort and a strategic approach, potentially through specializing in certain property types or geographic sub-markets. For real estate investors, this environment means that sourcing deals might be more efficient when working with proven agents who have a strong track record and deep local connections. Conversely, for those seeking to acquire properties without agent representation, such a concentrated market might require more extensive direct outreach using tools like skip tracing or bulk data delivery to identify potential sellers directly. Understanding the local dynamics, even in smaller counties like Union, is key to developing effective real estate investing strategies.
