Cassia (ID) Investor Pulse Report (2025-Q4)

In Cassia County, investors hold 987 Single-Family Residential (SFR) properties, representing 14.7% of the total 6,714 SFRs in the market.

Individual investors are the backbone of the local rental market, owning 734 properties, which accounts for 74.4% of the entire investor portfolio. In contrast, company-owned properties number 279, making up the remaining 28.3%.

A significant strategic pattern is the preference for cash acquisitions, with 741 properties (75.1% of the portfolio) held free of financing. This suggests a well-capitalized investor base less susceptible to interest rate fluctuations compared to the 246 financed properties.

The market structure consists of 1,072 distinct landlord entities, with individual landlords (882) outnumbering company landlords (190) by a ratio of more than 4.6 to 1, reinforcing the small-scale nature of property investment in the area.

The primary purpose of these holdings is clear, as 924 of the 987 properties (93.6%) are rented, confirming that the vast majority of the investor-owned portfolio serves as housing for tenants.

In a striking demonstration of purchasing power, landlords in Q4 2025 acquired properties for an average price of $259,966, a staggering 22.0% discount compared to the $333,274 paid by traditional homeowners. This equates to an average savings of $73,308 per property.

This significant Q4 discount represents a sharp trend reversal from the first half of the year. In Q2 2025, landlords actually paid a 1.8% premium ($6,532 more than homeowners), and in Q1, they paid a 1.5% premium ($5,529 more), indicating a dramatic shift in market dynamics that increasingly favored investors as the year concluded.

The average acquisition price for landlords has fluctuated significantly throughout 2025, from a high of $383,158 in Q1 to the low of $259,966 in Q4, highlighting market volatility and the ability of investors to capitalize on favorable conditions.

Compared to the pandemic-era boom (2020-2023), when the average landlord acquisition price was $244,786, the Q4 2025 price of $259,966 shows modest appreciation, but a notable cooling from the year's earlier peaks.

The widening price gap, from a $10,337 discount in Q3 to a $73,308 discount in Q4, signals that investors either possess a growing negotiation advantage or are targeting different types of properties than traditional homebuyers.

Investor activity accounted for 15.5% of the total market in Q4 2025, with landlords acquiring 13 of the 84 SFR properties sold in Cassia County.

The quarter was defined by the activity of small-scale investors, as mom-and-pop landlords (owning 1-10 properties) were responsible for 84.6% of all landlord purchases, totaling 11 properties.

New entrants are a key driver of the market, with 10 new single-property landlord entities acquiring 7 homes. This group alone represented 53.8% of all investor purchases, highlighting a continuous influx of first-time investors.

The mid-size and large investor tiers were minimally active, with one entity in the 11-20 property tier and one in the 101-1,000 property tier each purchasing a single property.

Institutional investors (1,000+ properties) were completely inactive on the buy-side in Q4, acquiring 0.0% of the properties and reinforcing the market's heavy reliance on smaller, local landlords.

The ownership structure of investor properties in Cassia County is overwhelmingly dominated by small landlords. Mom-and-pop investors, defined as those owning 1-10 properties (Tiers 01-04), collectively own 93.2% of all investor-held SFRs.

Single-property landlords (Tier 01) form the largest single segment, holding 602 properties, which represents 57.5% of the entire investor-owned housing stock. This highlights the deeply fragmented and small-scale nature of the rental market.

In stark contrast, institutional investors with portfolios exceeding 1,000 properties (Tier 09) have a minimal presence, owning just a single property, which amounts to only 0.1% of the investor market. This finding directly counters the narrative of large corporations controlling the local housing market.

Mid-size landlords (11-1000 properties) also hold a relatively small share, collectively owning 70 properties, or just 6.7% of the investor portfolio.

The distribution clearly shows that the rental housing supply in Cassia County is primarily provided by local, small-scale investors rather than large, corporate entities.

A clear ownership pattern emerges across portfolio sizes: individual investors control the smaller tiers, while companies dominate the larger ones. Individuals own a commanding 82.2% of single-property portfolios and maintain a majority through the 6-10 property tier (61.0%).

The crossover point where corporate ownership becomes dominant occurs in the 11-20 property tier (Small-medium). In this segment, companies own 20 properties (71.4%) compared to just 8 owned by individuals (28.6%).

This trend accelerates dramatically in the next tier up (21-50 properties), where companies own 36 of the 37 properties, a staggering 97.3% share. This indicates that scaling beyond 10 properties is almost exclusively done under a corporate structure.

Even in the two-property tier, company ownership is significant at 43.2%, suggesting that many investors formalize their holdings into a company structure early in their investment journey.

This data reveals a distinct strategic shift: portfolios of 10 or fewer properties are largely personal investments, while portfolios of 11 or more are typically operated as formal businesses.

Investor ownership in Cassia County is geographically concentrated, with the 83318 zip code (Burley) hosting the largest number of investor-owned properties at 752. This area serves as the primary hub for rental properties in the county.

While Burley (83318) leads in raw count, the highest market penetration is found elsewhere. The 83312 zip code (Albion) has the highest investor ownership rate at 22.4%, meaning more than one in five SFRs there is investor-owned.

Other areas with high investor concentration include the 83350 (Rupert) and 83342 (Malta) zip codes, with ownership rates of 19.1% and 16.2% respectively. These smaller communities have a significant portion of their housing stock serving as rentals.

This highlights a key distinction between volume and saturation. The largest urban center (Burley) has the most units, but smaller, surrounding communities have a higher percentage of their homes owned by investors.

The top five zip codes by property count—83318, 83323, 83346, and 83342—collectively house the vast majority of the county's investor-owned SFRs, indicating that investor focus is not evenly distributed.

Investors in Cassia County remain in a strong accumulation phase, consistently buying more properties than they sell. In Q4 2025, they were net buyers with 16 purchases versus only 5 sales, resulting in a net gain of 11 properties to their portfolios.

The buy-to-sell ratio in Q4 stood at 3.2, demonstrating robust confidence in the local market. This behavior was sustained throughout the year, with the full-year 2025 data showing 66 buys and 21 sells for a 3.14 ratio.

While still aggressive, the pace of acquisition has cooled compared to the previous year. In 2024, landlords were exceptionally active, buying 81 properties while selling only 13, for a much higher buy-to-sell ratio of 6.23.

Transaction volume shows seasonality, with Q3 2025 being the most active period for purchases (22 buys) and Q2 seeing the most sales (7 sells).

There is no transaction data available for institutional (1000+) investors, indicating their activity is either nonexistent or too low to register, leaving the market dynamics entirely driven by smaller landlords.

In Q4 2025, landlords were involved in 16 of the 130 total SFR transactions, capturing a 12.3% share of all market activity.

Transaction volume was heavily concentrated among the smallest investors. Mom-and-pop landlords (Tiers 01-04) conducted 14 of the 16 investor transactions, with single-property buyers alone accounting for 10 of them.

A surprising pricing pattern emerged this quarter, as the single large investor (101-1000 tier) paid the highest average price at $341,516 for its one purchase. In contrast, new single-property investors paid a much lower average of $273,093.

Inter-landlord trading was minimal among new entrants. Of the 10 properties purchased by single-property landlords, only 1 (10.0%) was acquired from another landlord, suggesting new investors are primarily buying from traditional homeowners.

Institutional investors (1000+ tier) recorded zero transactions, further confirming that Q4 market dynamics were shaped entirely by the actions of small to mid-sized local investors.
