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

Investor presence in Jerome County is substantial, with landlords owning 1,309 single-family residential properties, accounting for a significant 30.1% of the county's total SFR market of 4,354 homes.

The market is overwhelmingly dominated by individual investors, who own 1,020 properties, or 77.9% of the investor-held portfolio, compared to 308 properties (23.5%) owned by companies.

This individual dominance is also reflected in the entity count, where 1,179 individual landlords operate in the county, compared to just 180 company landlords, a ratio of more than 6 to 1.

Cash is the preferred method of acquisition for investors in Jerome County, with 859 properties owned outright versus 450 that are financed. This suggests a market with high liquidity and well-capitalized investors.

The portfolio is heavily focused on rental activity, with 1,288 properties identified as rented, representing 98.4% of all investor-owned SFRs and signaling a strong rental-driven strategy among local landlords.

Investors in Jerome County demonstrate a significant pricing advantage, acquiring properties in Q4 2025 for an average of $250,412, which is 30.6% less than the $360,984 paid by traditional homeowners.

This massive $110,572 discount per property in Q4 marks a sharp increase in investor purchasing power throughout the year, with the discount widening considerably from 18.2% ($62,505) in Q1.

The trend shows a volatile but strengthening investor advantage; the discount swelled from 22.4% in Q2 to an enormous 40.1% in Q3 before settling at 30.6% in Q4, indicating landlords are capitalizing on market conditions more effectively than homeowners.

The average landlord acquisition price across 2025 was $252,703, consistently staying well below the prices paid by the general public and showcasing a durable competitive edge in the market.

The consistent, substantial discount across all quarters of 2025 suggests that landlords in Jerome County are either targeting distressed properties or possess superior negotiation and deal-sourcing capabilities compared to the general public.

Investor activity surged in Q4 2025, with landlords acquiring 42 single-family homes, which represents a commanding 50.6% share of the 83 total SFR properties sold in Jerome County.

The backbone of this purchasing activity was mom-and-pop landlords (1-10 properties), who collectively bought 26 homes, accounting for 61.9% of all investor acquisitions during the quarter.

The market saw a significant influx of new investors, as 22 new entities purchased their very first rental property (Tier 01), making up 38.1% of all properties bought by landlords in Q4.

In stark contrast, institutional investors (1,000+ properties) had a minimal impact, purchasing just 2 properties, or 4.8% of the landlord total, reinforcing the local, small-investor character of the market.

Mid-size investors also showed notable activity, with those in the 11-20 property tier purchasing 8 homes (19.0%), indicating strategic portfolio growth beyond the entry level.

The investor landscape in Jerome County is unequivocally dominated by small-scale operators, with mom-and-pop landlords (owning 1-10 properties) controlling a massive 92.4% of all investor-owned SFRs.

Single-property landlords (Tier 01) form the bedrock of the market, owning 900 homes, which alone constitutes 67.5% of the entire investor portfolio and highlights the grassroots nature of local real estate investment.

Conversely, the presence of large institutional investors (Tier 09, 1,000+ properties) is virtually non-existent, with this tier owning just 2 properties, for a minuscule 0.1% market share.

The data reveals a steep drop-off in ownership as portfolio sizes increase; after the 1-10 property group, mid-size landlords (11-1000 properties) collectively own only 7.5% of the remaining investor-held homes.

This ownership structure indicates a highly fragmented market with a low barrier to entry, where individual financial capacity, rather than corporate strategy, is the primary driver of the rental housing supply.

While individual investors dominate the overall market, a clear crossover point occurs as portfolios grow: companies become the majority owners in the 11-20 property tier, holding 38 properties (69.1%) compared to individuals' 17 properties (30.9%).

In the smaller tiers, individual ownership is supreme. For single-property landlords, individuals represent 88.7% of all properties. This majority holds through the 2-property (68.1%), 3-5 property (60.2%), and 6-10 property (57.7%) tiers.

This pattern suggests that while individuals are the primary force for market entry and small portfolios, scaling beyond 10 properties often involves the formation of a company, likely for liability protection and financing advantages.

The 1-property tier shows a stark contrast in scale, with 813 properties owned by individuals versus just 104 owned by companies, reinforcing that the typical new landlord is an individual, not a corporation.

The transition to company-dominated ownership at the 11-property mark is a key structural feature of the Jerome County market, defining the boundary between smaller-scale personal investment and more formalized, larger-scale operations.

The vast majority of investor activity in Jerome County is concentrated in a single area, with zip code 83338 containing 1,088 investor-owned properties, representing 83.1% of the county's entire investor portfolio.

A key distinction exists between property volume and market penetration. While 83338 leads in raw numbers, the small zip code of 83325 has the highest density of investors, with 58.3% of its homes being investor-owned.

The investor ownership rate in 83338 is 28.3%, substantially lower than in 83325 (58.3%) and 83335 (35.6%), indicating that while investors flock to 83338, their market share is less dominant there compared to smaller, more saturated areas.

The top three zip codes for investor presence are 83338 (1,088 properties), 83335 (114 properties), and 83325 (105 properties), which together account for nearly all investor-owned SFRs in the county.

This high geographic concentration suggests that investors are targeting specific neighborhoods or communities within Jerome County, likely driven by factors like rental demand, property values, and local economic conditions.

Landlords in Jerome County are in a strong accumulation phase, demonstrating a clear net-buyer position with 55 purchases versus only 9 sales in Q4 2025, a buy-to-sell ratio of 6.1 to 1.

This aggressive acquisition strategy was sustained throughout the entire year. Across 2025, landlords purchased 133 properties while selling only 21, resulting in a net gain of 112 properties and a yearly ratio of 6.3 buys for every sale.

The data shows a consistent pattern of portfolio expansion, with landlords remaining net buyers in every quarter of 2025, including Q3 (19 buys, 2 sells) and Q2 (21 buys, 7 sells).

Transaction volume accelerated significantly toward the end of the year, with the 55 purchases in Q4 being nearly triple the volume of Q3 (19) and Q2 (21), signaling increasing investor confidence.

While comprehensive data for institutional investors (1000+ tier) was not available for comparison, the overall market trend is unambiguously one of growth and long-term holding driven by the broader landlord community.

Landlords played a pivotal role in the Q4 2025 market, participating in 55 of the 121 total SFR transactions, which translates to a significant 45.5% market share.

A clear divide in acquisition strategy appears by tier: institutional investors (1,000+ tier) heavily recycled existing rental stock, acquiring 66.7% of their properties from other landlords.

In contrast, new single-property landlords overwhelmingly bought from the open market, with only 9.1% of their 22 purchases coming from other investors, indicating they are primarily competing with traditional homeowners.

Entry-level investors paid a premium to enter the market. The single-property tier recorded the highest average purchase price at $265,786, notably higher than larger tiers like the 101-1000 group, which paid an average of $161,009.

Mom-and-pop landlords (Tiers 01-04) were the most active group, responsible for 35 transactions, far outpacing the 3 transactions conducted by institutional investors and reaffirming their dominance in market activity.
