San Juan (WA) Investor Pulse Report (2026-Q1)

In San Juan County, investors own 4,780 single-family residential properties, a significant 51.9% of the total 9,206 SFRs. This high penetration rate, visible in detailed property datasets, indicates a market heavily influenced by real estate investing activity.

The ownership structure is overwhelmingly composed of individual investors, who control 3,888 properties, or 81.3% of the investor-owned portfolio. Company-owned properties account for the remaining 1,056 properties (22.1%), highlighting the market's reliance on small-scale, non-corporate landlords.

By entity count, the disparity is even clearer, with 5,867 individual landlords compared to just 973 company landlords. This 6-to-1 ratio of individual to company entities reinforces the mom-and-pop character of the local rental market.

A strong preference for all-cash ownership is evident, with 3,394 properties held without financing. This is nearly 2.5 times the number of financed properties (1,386), suggesting a well-capitalized investor base that is less sensitive to interest rate fluctuations.

The portfolio is almost entirely focused on rentals, as 4,756 of the 4,780 properties (99.5%) are classified as non-owner-occupied. This near-total focus on rental income generation underscores the business-oriented nature of SFR ownership in the county.

The price relationship between landlords and traditional homeowners in San Juan County is highly volatile and defies simple trends. In Q1 2026, landlords acquired properties at an average price of $1,178,088, which was $114,848 (8.9%) less than the average homeowner price of $1,292,936.

However, this discount is a recent development and reverses a pattern of landlords paying significant premiums. Just two quarters earlier in Q3 2025, investors paid an average of $1,081,979, representing a 19.9% premium over the homeowner price of $902,132.

This quarter-over-quarter swing is not an isolated event. In Q1 2025, landlords also paid more than homeowners, with a 7.1% premium ($1,011,122 vs. $944,111). This pattern suggests that in this specific market, investors may be competing for high-value properties or operating with different strategic goals than typical homeowners.

The data does not show consistent purchasing volume across recent timeframes, with zero properties recorded for landlords in periods like 2024 and 2025. This makes it impossible to analyze price appreciation trends or acquisition momentum from the available information.

The lack of a consistent discount for investors is a key characteristic of the San Juan County market, indicating a competitive landscape where landlords do not always hold a pricing advantage.

Investor activity was a primary driver in the San Juan County housing market in Q4 2025, with landlords acquiring 21 of the 41 total SFRs sold. This represents a commanding 51.2% market share for the quarter, reinforcing the significant role investors play in the local real estate ecosystem.

The quarter's buying was exclusively fueled by mom-and-pop investors. Landlords in Tiers 01-04 accounted for all recorded investor activity, acquiring 22 properties in total. There was zero purchasing from mid-size or institutional tiers.

New entrants dominated the market. Single-property landlords (Tier 01) were the most active group, purchasing 17 properties, which represents 77.3% of all investor acquisitions for the period. This activity was spread across 21 new entities, signaling a fresh wave of small-scale investment.

Smaller, existing landlords also grew their portfolios. Investors in the two-property tier added 4 homes (18.2% of purchases), and those in the 3-5 property tier acquired 1 home (4.5%).

The complete absence of institutional buying alongside the surge in new, small landlords highlights a market characterized by grassroots growth rather than large-scale corporate consolidation.

The investor landscape in San Juan County is defined by the overwhelming dominance of small-scale operators. Mom-and-pop landlords, defined as those owning 1-10 properties (Tiers 01-04), control a staggering 99.7% of all investor-owned single-family homes.

This concentration at the small end of the market is even more pronounced when looking at the smallest tier. Single-property landlords (Tier 01) alone own 4,223 properties, which constitutes 85.3% of the entire investor-owned housing stock in the county.

As portfolio sizes increase, the number of properties drops off precipitously. Two-property landlords (Tier 02) hold 460 properties (9.3%), and those with 3-5 properties (Tier 03) own 231 properties (4.7%). All other tiers combined own less than 1% of the total.

The narrative of large corporations buying up housing does not apply here. Institutional investors (Tier 09, 1,000+ properties) have a negligible presence, owning just a single property. This equates to a market share of effectively 0.0%.

This ownership structure reveals a market built and maintained by thousands of individual and small family investors, not by large, consolidated corporate entities.

While individual investors dominate the overall ownership landscape in San Juan County, a clear crossover point exists where companies become the majority owners as portfolios grow. This transition occurs in the 11-20 property tier.

Among landlords owning 11-20 properties, companies control a decisive 87.5% share, owning 7 of the 8 properties in that tier. This marks a significant shift from smaller portfolio sizes, which are heavily skewed towards individual ownership.

In the largest tier of single-property landlords, individuals own 3,518 homes, representing 81.0% of that segment, while companies own 826 homes (19.0%). This pattern of individual dominance continues through the 2-property tier (74.2% individual) and the 3-5 property tier (63.6% individual).

The data suggests a strategic shift where investors managing larger, more complex portfolios are more likely to adopt a formal corporate structure. This is the first tier where the operational and legal benefits of incorporation appear to outweigh the simplicity of personal ownership.

Even in the 6-10 property tier, individuals still hold a majority at 61.9%, making the sharp reversal in the 11-20 property tier a key structural feature of the local investor market.

Investor ownership in San Juan County is not evenly distributed, showing intense geographic concentration in a handful of key areas. The top two zip codes, 98250 (Friday Harbor) and 98245 (Eastsound), together account for 2,943 investor-owned properties, representing 61.6% of the county's total investor portfolio.

The 98250 zip code is the epicenter of investment, with 1,889 properties owned by investors, giving it an ownership rate of 47.8%. The 98245 zip code follows with 1,054 properties and an even higher penetration rate of 53.9%.

While some smaller zip codes (98001, 98003, 98040) technically have a 100% investor ownership rate, this is likely due to a very small number of total properties. A more meaningful metric is seen in areas with both high rates and substantial property counts.

Zip code 98280 (Waldron) stands out in this regard, with one of the highest investor ownership rates at 71.5% across a significant portfolio of 226 properties. This indicates a market where rental or investment properties are the dominant form of housing.

This deep concentration suggests that investors are targeting specific communities, possibly driven by factors like vacation rental demand, local employment, or specific housing stock characteristics.

Landlords in San Juan County demonstrated a strong pattern of portfolio accumulation throughout 2024 and 2025, consistently acting as net buyers. In 2025, investors acquired 261 properties while only selling 20, a buy-to-sell ratio of over 13-to-1, signaling a clear strategy of expansion.

This trend of aggressive acquisition was consistent across recent quarters. In the third quarter of 2025, the activity was particularly pronounced, with 99 properties purchased versus only 4 sold. In the second quarter, 53 properties were bought against 5 sold.

The pattern holds true when looking at the full year 2024 as well, where landlords purchased 242 properties and sold a mere 10. This long-term, consistent net buying behavior points to strong confidence in the local rental market.

The data does not contain transaction information for institutional investors (1000+ tier), so their net position cannot be determined. However, given their minimal presence in the county (only one property owned), their transaction activity is presumed to be negligible.

The overwhelming net buyer status of the dominant mom-and-pop investor base is a defining feature of market dynamics, indicating that the investor-owned share of housing is actively growing.

Investors were a major force in the San Juan County market during the most recent quarter, participating in 29 of the 59 total SFR transactions. This 49.2% share underscores their significant and ongoing role in local market liquidity and sales volume.

All 29 of these transactions were driven by mom-and-pop landlords (Tiers 01-04), with no activity from institutional investors. New, single-property investors were the most active, accounting for 21 of the transactions.

A striking finding from the quarter's activity is the complete absence of inter-landlord trading. Zero percent of the properties purchased by investors were acquired from other landlords, indicating that the supply for investor acquisitions is coming entirely from the owner-occupied market.

Purchase prices varied significantly between the most active tiers. Two-property landlords paid the highest average price at $1,649,571 per property. This is 75% more than the $940,050 average paid by new single-property landlords, suggesting that more experienced small investors may be targeting higher-value assets.

This lack of a secondary market between investors and the premium prices paid by slightly larger landlords points to a competitive environment where investors are bidding against homeowners for desirable properties.
