Jerome (ID) Investor Pulse Report (2026-Q1)

Investors have a significant footprint in Jerome County, owning 1,315 Single-Family Residential (SFR) properties, which constitutes 30.2% of the total 4,355 SFRs in the market. This high penetration rate underscores the importance of real estate investing in the local housing ecosystem.

The ownership landscape is overwhelmingly dominated by individual investors rather than corporations. Individuals own 1,023 properties, or 77.8% of the investor portfolio, compared to 313 properties (23.8%) owned by companies. This 3-to-1 ratio highlights a market driven by local entrepreneurs and families.

When examining entity counts, the pattern of individual dominance is even more pronounced. There are 1,183 individual landlords compared to just 184 company landlords, meaning individuals make up 86.5% of all investor entities in the county.

In terms of financing, cash is the preferred method for holding properties. Investors own 862 properties with cash, nearly double the 453 properties that are financed. This suggests a well-capitalized investor base with lower leverage and risk.

The investor portfolio is almost entirely dedicated to rentals. A total of 1,293 properties, or 98.3% of the entire investor-owned stock, are rented. This extremely high rental rate indicates a market geared towards providing housing supply for tenants rather than speculative flipping.

Investors in Jerome County demonstrate a consistent ability to acquire properties at a significant discount compared to traditional homeowners. In Q1 2026, landlords paid an average of $282,194, which is $103,354, or 26.8%, less than the $385,548 paid by homeowners.

This pricing advantage for investors is not an anomaly, though its magnitude varies. The discount has been volatile over the past year, reaching a peak of 40.1% in Q3 2025 before settling at the current 26.8% rate. This fluctuation suggests investors are capitalizing on specific market opportunities as they arise.

Long-term price appreciation is evident when comparing current prices to historical data. The average acquisition price during the 2020-2023 period was $247,518, indicating a notable increase in property values over the last few years.

However, the most recent trend shows a slight market softening. The Q1 2026 average price of $282,194 is below the 2024 full-year average of $292,500, suggesting that the rapid price growth of the pandemic era may be leveling off.

The consistent ability to purchase below the homeowner market rate points to sophisticated acquisition strategies, such as finding off-market deals or targeting properties that require renovations, allowing investors to build equity immediately upon purchase.

Investor purchasing activity was a major force in the Jerome County market during Q4 2025, with landlords acquiring 18 of the 46 total SFRs sold, capturing a 39.1% market share.

The acquisition activity was dominated by mom-and-pop landlords (1-10 properties), who were responsible for 16 of the 18 investor purchases, or 88.9% of the total. In stark contrast, institutional investors (1,000+ properties) made only one purchase, accounting for just 5.6% of investor activity.

Growth in the investor community is being driven by new entrants. The single-property tier was the most active, with 16 different entities purchasing 13 properties. This influx of new, small-scale landlords is the primary engine of market expansion.

This pattern reinforces that the local investment scene is characterized by grassroots participation rather than large-scale corporate acquisitions. The market is expanding one property at a time, driven by individual investors.

The minimal presence of institutional buyers alongside the high volume of new landlords suggests a healthy, decentralized market where opportunities are accessible to smaller players.

The distribution of property ownership in Jerome County heavily favors small-scale investors. Mom-and-pop landlords, defined as those owning 1-10 properties, collectively control a staggering 92.2% of all investor-owned SFRs.

This concentration at the smaller end of the market directly counters the narrative of a corporate takeover. Institutional investors with portfolios exceeding 1,000 properties own only 4 homes in the county, representing a negligible 0.3% of the investor market.

The single-property landlord tier is the bedrock of the entire rental market. This group owns 904 properties, accounting for 67.4% of all investor-held housing. This signifies that the vast majority of landlords are community members investing in their first rental property.

Mid-size landlords (11-100 properties) also have a limited presence, controlling a combined 7.6% of the portfolio. The data clearly illustrates a highly fragmented market composed of thousands of small owners.

The ownership structure indicates that the local rental housing supply is overwhelmingly provided by small, local investors, not by large, out-of-state corporations.

A distinct pattern emerges when analyzing ownership by entity type across different portfolio sizes. Individual investors are the dominant force in smaller tiers, while companies take control as portfolios grow.

The crossover point occurs at the 11-20 property tier. In this segment, companies own 39 properties (69.6%), marking the first tier where corporate ownership surpasses individual ownership. This suggests investors tend to incorporate their holdings as their business scales.

At the entry level, individual ownership is nearly absolute. In the single-property tier, 88.5% of homes are owned by individuals. This share gradually decreases as portfolio size increases, falling to 58.5% in the 3-10 property range.

The data illustrates a typical investor lifecycle: individuals enter the market, and as their portfolio expands beyond about 10 properties, they are more likely to adopt a formal corporate structure for management and liability purposes.

Even in the company-dominated 11-20 property tier, individuals still maintain a notable presence, owning 17 properties (30.4%), highlighting that not all large portfolios are corporatized.

Geographic analysis reveals that investor activity in Jerome County is not widespread but is instead highly concentrated in a few key areas. The 83338 zip code is the epicenter, containing 1,097 investor-owned properties, which is 83.4% of the entire investor portfolio in the county.

The data highlights a crucial difference between investment volume and market saturation. While 83338 is the clear leader in the number of investor properties, its investor ownership rate is 28.5%.

In contrast, the 83325 zip code has a much smaller portfolio of 102 investor-owned homes but boasts the highest saturation rate at 56.7%. In this area, more than half of all single-family homes are owned by investors, indicating a market dominated by rental properties.

This pattern suggests different investment strategies are at play. The 83338 area represents a large, stable rental market, while the high-saturation 83325 area may represent a market with fewer homeownership opportunities and a greater reliance on rental housing.

Outside of these key zip codes, investor presence drops off sharply, pointing to a localized investment approach focused on specific community characteristics and using precise assessor data to identify opportunities.

Transactional data shows that landlords in Jerome County are in a sustained accumulation phase, consistently buying far more properties than they sell. In Q1 2026, they demonstrated strong market confidence by purchasing 24 homes while only selling 5, a buy-to-sell ratio of 4.8x.

This net buyer behavior is a multi-year trend. In 2025, landlords purchased 137 properties and sold only 19 (a 7.2x ratio). The trend was even stronger in 2024, with 119 buys versus just 9 sells (a 13.2x ratio).

While landlords remain firmly in a growth mode, the declining buy-to-sell ratio, from 13.2x in 2024 to 4.8x in the latest quarter, signals that the pace of portfolio expansion is moderating. This could be due to rising prices, tighter inventory, or a strategic shift to a more sustainable growth rate.

The consistent, high-volume net buying activity confirms that investors see long-term value in the Jerome County rental market and are actively increasing their holdings.

This ongoing acquisition trend is a primary driver of the increasing investor market share in the county, reshaping the local housing landscape one transaction at a time.

In Q1 2026, landlords played a pivotal role in market liquidity, participating in 24 of the 61 total SFR transactions, which represents a 39.3% share of all activity.

A surprising pricing pattern emerged among different investor tiers. The smallest investors, those in the single-property tier, paid one of the highest average prices at $288,468. This is significantly more than the $219,450 paid by mid-size investors in the 11-20 property tier, suggesting new entrants may be paying a premium to enter the market.

Acquisition sources reveal a clear strategic divide. All 21 purchases made by mom-and-pop investors (Tiers 1-4) were from non-landlord sellers, indicating they are acquiring properties from the traditional homeowner market.

Conversely, the single transaction by an institutional investor was a landlord-to-landlord deal. This suggests that at the highest level, activity consists of portfolio trades between established players rather than new acquisitions from the open market.

New and small investors were the most active group, with the single-property tier alone accounting for 17 of the 24 landlord transactions. This reinforces that market growth is fueled by new capital from grassroots investors.
