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

Investors hold a significant 32.3% share of the single-family residential market in Blaine County, with a total portfolio of 3,205 properties out of 9,912 total SFRs.

Individual investors form the backbone of the market, owning 2,457 properties (76.7% of the investor portfolio), while company-owned entities hold 1,126 properties (35.1%).

There are 3,470 individual landlords compared to 1,053 company landlords, a ratio of more than 3 to 1, reinforcing the dominance of small-scale ownership in the county.

Cash is the preferred method of ownership, with cash-owned properties (2,257) outnumbering financed ones (948) by nearly 2.4 to 1, suggesting a well-capitalized investor base.

The portfolio is heavily geared towards rentals, with 3,142 of 3,205 investor properties (98.0%) being non-owner-occupied, highlighting the area's role as a key rental market.

In a striking deviation from typical market behavior, landlords in Blaine County paid a substantial 30.4% premium for properties in Q4 2025, with an average price of $1,389,338 compared to the traditional homeowner price of $1,065,694.

This translates to an average overpayment of $323,644 per property, indicating intense competition for desirable homes, likely for high-yield vacation rentals.

The trend of investors paying more than homeowners was persistent throughout the year, with premiums of 14.2% in Q3, 19.4% in Q2, and a staggering 45.5% in Q1 2025.

This sustained premium suggests that investors are valuing properties based on potential income or long-term appreciation in a high-demand resort area, rather than seeking discounted acquisition costs.

The data shows a significant price appreciation from the 2020-2023 period, where the average landlord acquisition price was $935,079, to the Q4 2025 average of $1,389,338.

Investor activity was a powerful force in the Blaine County market during Q4 2025, with landlords acquiring 37 of the 96 available single-family properties, a market share of 38.5%.

The market's growth is fueled by new, small-scale investors, evidenced by the 42 new single-property entities that entered the market this quarter, purchasing 28 homes.

Mom-and-pop landlords (owning 1-10 properties) completely dominated acquisition activity, making up 39 of the 40 total investor-attributable purchases, or 97.5% of the volume.

Single-property landlords were the most active group, single-handedly responsible for 28 purchases, which represents 70.0% of all investor buying activity.

Institutional investors were entirely absent from the market, making no purchases in Q4 and highlighting that the area's investor landscape is exclusively controlled by smaller operators.

The investor market in Blaine County is characterized by an overwhelming concentration of small-scale ownership, with mom-and-pop landlords (1-10 properties) controlling 99.2% of all investor-held SFRs.

First-time or single-holding investors are the most significant segment, with the '1 property' tier alone accounting for 2,653 properties, or 78.7% of the total investor portfolio.

The next two tiers, '2 properties' and '3-5 properties', add another 653 properties, making up a combined 19.4% of investor ownership.

As portfolio size increases, the number of properties drops off dramatically, with only 21 properties (0.6%) held by landlords in the 11-20 property tier.

Institutional capital is non-existent in this market, as investors with portfolios of 1,000 or more properties have a 0.0% share, underscoring the hyper-local, small-investor nature of the region.

Individual investors are the primary force in the entry-level tiers, owning 2,100 properties (71.6%) in the single-property tier and 228 properties (64.4%) in the two-property tier.

A distinct crossover point occurs in portfolios of 6-10 properties, where company ownership jumps to a dominant 76.9% share, indicating a strategic shift to corporate structures as portfolios scale.

This trend accelerates in larger tiers, with companies owning 20 of the 21 properties (95.2%) in the 11-20 property range.

For portfolios between 3 and 5 properties, ownership remains majority individual at 65.7%, suggesting that incorporation typically happens after an investor surpasses five properties.

This data clearly illustrates the investor lifecycle in Blaine County: individuals initiate investment activity, but scaling and professionalization are achieved through company structures.

Investor ownership in Blaine County is highly concentrated geographically, with the top three zip codes—83340 (Ketchum), 83333 (Hailey), and 83353 (Sun Valley)—accounting for 2,830 of the 3,205 investor-owned properties (88.3%).

The zip code 83340 holds the largest number of investor properties at 1,150, which constitutes an investor ownership rate of 49.7% for that area.

Some areas exhibit hyper-saturation of investor ownership, far exceeding the county average. Zip code 83352 leads with a 73.3% investor ownership rate, followed by 83353 (55.7%) and 83340 (49.7%).

The data reveals a strong correlation between areas with a high count of investor properties and those with a high percentage rate, indicating that investors are targeting the same core, high-demand areas.

This geographic clustering points to a market heavily influenced by vacation rental demand and second-home ownership in and around the Sun Valley resort area.

Investors in Blaine County are in a strong accumulation phase, demonstrated by a buy-to-sell ratio of 6.3x in Q4 2025, with 57 properties purchased versus only 9 sold.

This aggressive net buying behavior has been sustained throughout the year, with a total of 281 properties bought and just 35 sold in 2025, resulting in a net gain of 246 properties for investors.

The transaction velocity shows a strong and consistent appetite for acquisitions, with 2025's purchase volume (281) already exceeding the full-year total for 2024 (219).

The market shows no signs of institutional activity, as the 1,000+ property tier recorded zero buy or sell transactions in any tracked timeframe.

The high volume of net acquisitions signals strong investor confidence in the future value and income potential of Blaine County real estate.

Landlords played a crucial role in market liquidity during Q4, participating in 57 of the 160 total transactions, for a 35.6% market share.

Activity was almost exclusively driven by mom-and-pop investors (Tiers 01-04), who were responsible for 56 of the 57 landlord transactions.

New or single-property landlords were the most active, conducting 42 transactions and paying a high average purchase price of $1,060,200, which aligns with the finding that investors are paying a market premium.

Inter-landlord trading is minimal among new investors, with only 4 of the 42 single-property tier transactions (9.5%) sourced from other landlords, suggesting they are primarily buying from traditional homeowners.

There were zero transactions from institutional investors, confirming their complete lack of participation in the buying or selling activity within Blaine County.
