San Juan (WA) Investor Pulse Report (2025-Q4)

Investors hold a majority stake in the San Juan County housing market, owning 4,821 of the 9,136 Single-Family Residences, which constitutes a 52.8% market share.

Individual investors are the primary drivers of this market, owning 3,914 properties (81.2%), while company-owned properties number 1,085 (22.5%). This demonstrates a market dominated by smaller-scale participants rather than large corporations.

There is a strong preference for cash ownership among landlords in the county. Cash-owned properties (3,426) are more than double the number of financed properties (1,395), indicating a well-capitalized investor base.

The investor portfolio is clearly geared towards generating rental income. An overwhelming 99.6% of investor-owned SFRs (4,802 out of 4,821) are non-owner-occupied, underscoring the rental-centric strategy of local landlords.

The market consists of 6,928 distinct landlord entities, with individual landlords (5,932) vastly outnumbering company landlords (996), reinforcing the 'mom-and-pop' character of San Juan County's investor landscape.

In Q4 2025, landlords demonstrated significant purchasing power, acquiring properties for an average of $904,755, which is 14.5% less than the $1,057,679 paid by traditional homeowners—a substantial discount of $152,924 per property.

This Q4 discount represents a stark market shift. In the three preceding quarters of 2025, landlords were paying considerable premiums over homeowners, including a 42.2% premium ($323,589) in Q3 and a 23.6% premium ($199,073) in Q1.

The acquisition price trend indicates a cooling market for investors. The Q4 average price of $904,755 is not only lower than previous quarters in 2025 but also slightly below the average price of $918,006 from the 2020-2023 boom years, defying typical appreciation trends.

The dramatic swing from paying large premiums to securing a deep discount within a single year suggests a rapid change in market dynamics, potentially giving seasoned investors an advantage over traditional buyers in the current environment.

Investor activity reached a remarkable peak in Q4 2025, with landlords acquiring 45 of the 60 total SFRs sold, capturing a 75.0% share of all market purchases.

The 'mom-and-pop' segment was the exclusive driver of this activity. Investors with portfolios of 1-10 properties (Tiers 01-04) made up 97.9% of all landlord acquisitions, totaling 46 properties.

The market saw a significant influx of new participants, with 58 new single-property landlord entities entering the market and acquiring 36 homes, which represents 76.6% of all investor-bought properties for the quarter.

In stark contrast to the hyperactivity of small investors, institutional investors (Tier 09) were entirely inactive, acquiring zero properties in Q4. This highlights a market exclusively shaped by smaller, local players.

The data reveals a clear pattern of market absorption by small-scale investors, with a single entity in the 11-20 property tier being the largest active buyer in the fourth quarter.

The investor landscape in San Juan County is unequivocally dominated by small-scale landlords. 'Mom-and-pop' investors (Tiers 01-04, 1-10 properties) own 99.6% of all investor-held SFRs, dispelling any notion of significant corporate control.

First-time or single-property landlords form the bedrock of the market, with this tier alone accounting for 4,256 properties, which is 85.1% of the entire investor portfolio.

The scale of small investor dominance is profound. The first three tiers combined (1-5 properties) represent 99.2% of all investor-owned homes, showing extreme concentration at the smallest end of the spectrum.

Institutional ownership is virtually nonexistent in this market. Investors in the 1,000+ property tier (Tier 09) own just one property, accounting for a statistically insignificant 0.0% share.

The market structure reveals a highly fragmented ownership base, with thousands of small landlords shaping the rental market rather than a few large entities.

A clear bifurcation exists between individual and company ownership based on portfolio size. Individual investors are dominant in smaller tiers, holding 80.8% of single-property portfolios and 74.4% of two-property portfolios.

The strategic crossover point occurs in the 11-20 property tier (Small-medium). At this level, company ownership surges to 90.0%, indicating that scaling beyond 10 properties is primarily a corporate endeavor in this market.

Even in the 3-5 property tier, companies have a substantial presence, owning 95 properties for a 39.1% share, suggesting that incorporation is a common strategy even for relatively small but growing landlords.

This pattern reveals that while individuals form the foundation of the market, portfolio growth and professionalization are strongly correlated with a shift to a corporate ownership structure.

Investor ownership in San Juan County is not evenly distributed but is instead highly concentrated in a few key areas. The top five zip codes by property count (98250, 98245, 98261, 98279, 98280) contain a combined 4,210 properties, representing 87.3% of the entire investor portfolio.

The zip code 98250 is the epicenter of investor activity, with 1,905 landlord-owned SFRs, though its investor ownership rate is 48.5%.

A distinction exists between high-volume and high-penetration areas. Several small zip codes (98001, 98003, 98040) report a 100.0% investor ownership rate, suggesting these are small, exclusive investor enclaves.

The 98280 zip code stands out as a hotspot for both volume and penetration, ranking in the top five for both metrics with 229 investor-owned properties and a high 72.0% ownership rate.

This geographic clustering indicates that investors are targeting specific communities, leading to hyper-localized markets where landlord activity has an outsized impact on housing availability and pricing.

Landlords in San Juan County are in a phase of aggressive accumulation, acting as strong net buyers. In Q4 2025, they purchased 73 properties while selling only 6, resulting in a buy-to-sell ratio of over 12-to-1.

This net buying behavior is a persistent trend, not a quarterly anomaly. Landlords were also significant net buyers for the full years of 2025 (260 buys vs. 19 sells) and 2024 (256 buys vs. 13 sells).

The high volume of acquisitions compared to dispositions signals strong investor confidence and a long-term hold strategy prevalent in the county.

With institutional transaction data unavailable, the market's transactional behavior is entirely reflective of the smaller 'mom-and-pop' investors who are actively expanding their portfolios.

The consistent net buying pressure from this large base of small investors is a primary factor driving the high landlord market share in the county.

Landlords were the dominant force in the Q4 2025 market, participating in 73 of the 98 total transactions, a commanding 74.5% share of all activity.

A clear pricing hierarchy emerged among tiers. New investors in the single-property tier paid the highest average price at $885,887, suggesting a willingness to pay a premium to enter the market.

In contrast, more established small landlords in the 3-5 property tier acquired homes for a lower average price of $694,823, indicating that experience may lead to more favorable purchasing strategies.

The largest transaction of the quarter was an outlier, with a single property purchased by an entity in the 11-20 tier for $1,800,000, skewing the overall average.

Investors are primarily acquiring properties from the open market, not from each other. Only 8.6% of purchases made by single-property landlords were from other landlords, showing that the majority of new inventory is coming from former homeowners.
