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

In Bonneville County, investors hold a total of 4,194 Single-Family Residential (SFR) properties, which constitutes 11.8% of the total 35,612 SFRs in the market. This demonstrates a significant, yet not overwhelming, investor presence in the local housing landscape.

Individual investors are the primary drivers of the rental market, owning 3,115 properties, or 74.3% of the total investor portfolio. Companies own the remaining 1,161 properties (27.7%), indicating that the market is defined by smaller-scale real estate investing rather than large corporate ownership.

The investor portfolio is overwhelmingly focused on generating rental income, with 4,029 properties (96.1%) currently rented. This high rental concentration underscores the role these properties play in supplying housing for the local community.

When analyzing financing, cash is the preferred method for acquisitions. Investors own 2,663 properties outright, compared to 1,531 that carry a mortgage. This 1.7-to-1 cash-to-financed ratio suggests that many investors have significant capital and are less reliant on leverage.

The market structure consists of 4,684 distinct landlord entities, with individual landlords (3,950) outnumbering company landlords (734) by more than five to one. This further reinforces the 'mom-and-pop' character of Bonneville County's investor landscape.

In Q1 2026, investors in Bonneville County demonstrated a distinct pricing advantage, acquiring properties for an average of $354,241 while traditional homeowners paid $413,572. This represents a substantial 14.3% discount, saving investors an average of $59,331 on each purchase.

This price gap, while still significant, has tightened considerably over the past year. In Q1 2025, landlords secured an even larger 25.0% discount ($103,570). The narrowing gap indicates that the market is becoming more competitive, reducing the pricing power investors previously held.

The trend of a shrinking discount continued throughout 2025, moving from 25.0% in Q1 to 16.6% in Q2 and just 8.6% in Q3. The rebound to a 14.3% discount in the latest quarter suggests a potential stabilization of this dynamic.

Examining longer-term price appreciation, the average investor acquisition price in 2024 was $400,325. This highlights the volatility in quarterly pricing, as the Q1 2026 average of $354,241 is lower than the annual average from two years prior.

This consistent ability to purchase below the homeowner average suggests investors are targeting different types of properties or are more effective at negotiation, perhaps using tools like an automated valuation (AVM) to identify undervalued assets.

In Q4 2025, investors purchased 46 of the 394 SFR properties sold in Bonneville County, capturing 11.7% of the total market activity. This level of activity highlights a steady and continued interest from investors in expanding their local portfolios.

The purchasing activity was almost entirely driven by small-scale investors. Mom-and-pop landlords (owning 1-10 properties) accounted for 43 of the 46 investor purchases, representing a dominant 89.6% share of acquisition volume.

In stark contrast, institutional investors (1,000+ properties) made no purchases in Bonneville County during the quarter. This zero-activity level underscores their minimal impact on the local market, which is defined by smaller players.

New market entrants were a significant force, with 29 new landlords making their first rental property purchase. These single-property owners acquired 24 homes, accounting for 50.0% of all properties bought by investors in Q4.

The data reveals a clear pattern: the lifeblood of investor activity in Bonneville County is not large corporations, but new and existing small landlords building their portfolios one or two properties at a time, often using a property search platform to find opportunities.

The ownership structure of investor properties in Bonneville County is heavily concentrated at the small-scale level. Mom-and-pop landlords, defined as those owning 1-10 properties, control a massive 94.4% of all investor-owned SFRs.

Single-property landlords (Tier 01) form the bedrock of the rental market, owning 2,751 properties. This represents 62.4% of the entire investor portfolio, highlighting the critical role of first-time and small-scale investors in providing rental housing.

Conversely, institutional investors (Tier 09) have a negligible footprint in the county. Their portfolio of just 4 properties amounts to only 0.1% of the investor market, challenging any narrative of a corporate takeover of local housing.

The mid-size landlord category (11-1,000 properties) collectively owns the remaining 5.5% of the portfolio. This segment, while larger than the institutional tier, still plays a minor role compared to the thousands of small landlords.

This distribution, detailed in our property ownership by owner type report, confirms that market power is highly decentralized and lies firmly in the hands of local and small-scale operators.

A clear trend emerges when analyzing ownership by entity type across portfolio sizes: individuals dominate smaller tiers, while companies control larger ones. Individual landlords own 83.6% of single-property portfolios and 71.2% of two-property portfolios.

The market reaches a critical inflection point in the 6-10 property tier. At this level, company ownership surpasses individual ownership for the first time, with companies holding 153 properties (53.9%) compared to individuals' 131 properties (46.1%).

This pattern accelerates in larger tiers. In the 21-50 property bracket, companies control 62.7% of the properties. This suggests that as investors scale their operations, they are more likely to incorporate for liability and financial reasons.

At the highest end of the local market (101-1,000 properties), company ownership is almost total. Companies own 23 of the 25 properties in this tier, a commanding 92.0% share.

This crossover from individual to company control as portfolios grow indicates a professionalization trend. What starts as a personal investment often transitions into a formal business structure to manage a larger number of assets.

Geographic analysis of Bonneville County reveals significant concentration of investor ownership in specific zip codes. The 83428 zip code stands out with an investor ownership rate of 51.9%, meaning more than half of all SFRs there are investor-owned.

There is a clear distinction between areas with the highest count versus the highest percentage of investor properties. The 83401 zip code has the most investor-owned homes at 1,279, but its ownership rate is a more modest 10.4%.

In contrast, areas with the highest penetration rates, like 83428 (51.9%), 83285 (40.0%), and 83449 (37.6%), represent markets where investors have a much deeper presence relative to the total housing stock.

The top five regions by investor-owned property count are 83401 (1,279), 83402 (1,032), 83404 (737), 83406 (654), and 83428 (243). These five zip codes collectively account for a large portion of the county's rental housing.

This data, often visualized in market reports, shows that investor strategy is not uniform across the county. Some areas are targeted for scale, while others are targeted for market saturation.

Transaction data reveals that landlords in Bonneville County are in an accumulation phase. In Q1 2026, they purchased 54 properties while selling only 24, resulting in a net gain of 30 properties and a strong 2.25-to-1 buy-to-sell ratio.

This net-buyer behavior is a long-term trend. In the full year of 2025, investors bought 222 properties and sold 93 (a 2.4x ratio). The pattern was even stronger in 2024, with 334 buys versus 96 sells (a 3.5x ratio), indicating sustained portfolio growth over several years.

Even the small contingent of institutional investors (1,000+ properties) are expanding their local footprint. In 2025, this group acquired 8 properties and sold only 1, signaling a strategy of targeted growth rather than divestment.

This consistent net buying activity across all investor types demonstrates strong confidence in the Bonneville County rental market. Investors are actively choosing to increase their holdings rather than exit their positions.

Analyzing historical buying and selling provides insight into market liquidity and sentiment, often supplemented with deeper mortgage transaction data to understand financing trends behind these moves.

In Q1 2026, landlords participated in 54 of the 567 total SFR transactions in Bonneville County, giving them a 9.5% share of market activity. This shows a continued, albeit minority, role in the flow of property sales.

Transaction volume was dominated by mom-and-pop investors (Tiers 01-04), who were responsible for 49 of the 54 landlord transactions. Single-property landlords were the most active group, making up 29 of these transactions.

A clear pricing difference emerged by tier. New single-property investors paid the highest average price at $379,177. In contrast, small landlords in the 3-5 property tier acquired homes for a much lower average of $81,127, suggesting they are targeting different segments of the market or finding better deals.

Sourcing strategies also vary by size. Large landlords (101-1000 tier) engaged in landlord-to-landlord deals, with 100% of their purchases coming from other investors. Meanwhile, new single-property landlords sourced only 10.3% of their purchases from other investors, primarily buying from homeowners.

Institutional investors (1000+ tier) recorded zero transactions in the quarter, reinforcing their passive role in the day-to-day market churn in Bonneville County.
