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

In Mason County, IL, investors hold a significant 999 Single-Family Residential (SFR) properties, which constitutes 18.0% of the total 5,561 SFRs in the market.

The ownership structure is overwhelmingly dominated by individual investors, who own 906 properties (90.7%), compared to just 112 properties (11.2%) held by companies. This highlights a market driven by local, small-scale operators rather than large corporations.

A striking financial pattern emerges from the holdings data: 837 properties (83.8%) are owned outright with cash, while only 162 are financed. This indicates that investors in this market possess high liquidity and may be less sensitive to interest rate fluctuations.

The portfolio is heavily geared towards generating rental income, with 954 of the 999 properties (95.5%) actively rented. This demonstrates a clear strategy focused on buy-and-hold for cash flow.

The entity count further underscores the market's granular nature. There are 1,075 distinct landlords, with 980 being individuals and only 95 being companies, a ratio of more than 10 to 1.

Investors in Mason County secured properties at a massive discount in Q4 2025, paying an average of $68,500. This was 46.8% less than the $128,851 average paid by traditional homeowners, representing a price advantage of $60,351 per property.

This significant price gap is not an anomaly but a persistent market feature. Throughout 2025, the investor discount remained substantial, ranging from 42.0% in Q2 to a high of 50.9% in Q1, indicating a consistent ability to acquire lower-cost inventory.

The price gap widened slightly from Q2 to Q4. In Q2, the dollar difference was $48,816, which grew to $70,774 in Q3 before settling at $60,351 in Q4, showing the dynamic nature of this purchasing advantage.

Comparing prices over time, landlord acquisition costs have fluctuated, with the 2025 yearly average at $66,481, slightly up from the 2024 average of $65,523 and the 2020-2023 average of $61,938.

The data suggests investors in this market specialize in acquiring properties at a much lower price point than the general market, likely targeting distressed, as-is, or undervalued assets that traditional buyers may overlook.

Investor activity accounted for 23.3% of the Mason County market in Q4 2025, with landlords purchasing 14 of the 60 total SFRs sold.

The entirety of this purchasing activity came from mom-and-pop landlords (1-10 properties), who acquired all 14 properties. This demonstrates that small, local investors were the sole drivers of landlord acquisitions in the quarter.

Institutional investors (1,000+ properties) made no purchases in Q4, underscoring their lack of presence and influence in this local market's current transaction landscape.

New entrants are a key feature of the market, with the single-property tier accounting for 13 of the 14 properties purchased (92.9%). This indicates a healthy influx of first-time or small-scale investors.

The acquisitions were highly concentrated at the smallest scale, with 19 distinct entities purchasing 13 properties in the single-property tier, suggesting some properties may have been acquired through co-ownership arrangements.

The investor landscape in Mason County is unequivocally dominated by small-scale operators. Mom-and-pop landlords, defined as those owning 1-10 properties (Tiers 01-04), control 98.2% of all investor-owned SFRs.

The backbone of this market is the single-property landlord. This tier alone accounts for 742 properties, representing 71.4% of the entire investor portfolio, making first-time and small landlords the most critical segment.

Mid-size landlords (11-100 properties) have a very limited footprint, collectively owning only 10 properties, or 1.0% of the investor-owned housing stock.

Despite national narratives, institutional investors (1,000+ properties) have a negligible presence here, owning just 9 properties. This amounts to a mere 0.9% market share, confirming that 'Wall Street' is not a significant factor in Mason County's rental market.

This distribution reveals a highly fragmented market structure, where ownership is spread across many small landlords rather than concentrated in the hands of a few large players.

Individual investors maintain majority ownership across every single investor tier in Mason County, a clear sign that corporate ownership has not penetrated the market at any scale.

In the largest and most active tier (single-property), individuals own 677 properties (90.5%), while companies own just 71 (9.5%). This pattern of individual dominance continues up the scale.

Unlike larger urban markets, there is no 'crossover point' where companies become the majority owners. For instance, in the 6-10 property tier, individuals still hold a commanding 77.3% share.

Even in the small 21-50 property tier, individual owners hold 2 of the 3 properties (66.7%), reinforcing the trend that as portfolios grow, they tend to remain under personal ownership rather than corporate structures.

This data firmly establishes the Mason County investor market as one built and scaled by individual entrepreneurs, not corporate entities, regardless of portfolio size.

Geographic analysis reveals distinct patterns of investor concentration within Mason County. The zip code 62644 (Havana) is the epicenter of investor ownership by sheer volume, hosting 407 investor-owned properties.

However, the highest market penetration is found elsewhere. The 62617 (Easton) zip code has the greatest investor saturation, with a 28.9% ownership rate, meaning nearly three in every ten homes are owned by investors.

This highlights a key distinction between volume and density. While 62644 has the most units, smaller zip codes like 62617 and 61567 (26.1% rate) show a proportionally larger investor footprint.

The top five zip codes by investor property count are 62644 (407), 62664 (133), 61546 (113), 62617 (99), and 61567 (45), showing a steep drop-off after the top region.

The data for zip code 61534 shows no recorded investor properties, indicating it is either an area with no investor presence or a potential data gap.

Transaction data reveals a clear trend of portfolio expansion among Mason County landlords, who have consistently been strong net buyers. In 2025, they acquired 60 properties while selling only 15, a buy-to-sell ratio of 4-to-1.

This acquisitive behavior has been steady throughout the year, with landlords ending every quarter as net buyers. Q4 2025 saw 20 purchases versus 9 sales, resulting in a net gain of 11 properties.

In a striking contrast, the small institutional tier (1,000+ properties) has been divesting. In 2024, this tier was a net seller, acquiring 2 properties but selling 3, indicating a retreat from the market while smaller investors expand.

The data for 2025 builds on a pattern of accumulation from the previous year. In 2024, landlords were also significant net buyers, purchasing 57 properties and selling only 11, for a net gain of 46 properties.

This divergence in strategy—aggressive buying from the broader landlord community versus selling from the institutional tier—highlights two very different outlooks on the Mason County market.

In Q4 2025, landlords played a role in 23.3% of the 86 total SFR transactions in Mason County, with 20 landlord-involved purchases.

The market's activity was driven exclusively by its smallest players. Mom-and-pop landlords (Tiers 01-04) accounted for all 20 transactions, with 19 of those coming from the single-property tier alone.

A clear pricing strategy emerges by tier. The single-property investors, who dominated transaction volume, paid an average of just $65,176 per property. This is nearly half the price of the one transaction recorded by a slightly larger investor (3-5 property tier) at $125,000.

There is a notable level of inter-landlord trading among new entrants. Of the 19 properties bought by single-property investors, 5 were purchased from other landlords, a rate of 26.3%. This suggests a liquid market for rental properties among small investors.

Institutional investors were completely absent from Q4 transactions, recording zero purchases and reinforcing their passive, and even divestive, role in the market.
