San Diego (CA) Investor Pulse Report (2025-Q4)

Investors own 77,639 Single-Family Residential (SFR) properties in San Diego County, representing a significant 13.6% share of the total 571,649 SFRs in the market.

Individual investors are the backbone of the rental market, owning 63,400 properties, which accounts for 81.7% of all investor-owned SFRs. In contrast, company-owned portfolios consist of 19,071 properties, or 24.6% of the total.

The market is composed of 108,406 distinct landlord entities, with individual landlords (91,782) outnumbering company landlords (16,624) by a ratio of more than 5-to-1, reinforcing the dominance of small-scale operators.

When it comes to financing, 47,098 investor-owned properties are financed, compared to 30,541 that are owned outright with cash. This indicates that leverage remains a key strategy for real estate investors in the region.

The portfolio is heavily geared towards rental use, with 76,224 properties (98.2% of the total) classified as rented. This near-total saturation underscores the primary business objective of these property owners.

In a surprising reversal of typical market dynamics, landlords in San Diego County paid more than traditional homeowners in Q4 2025. The average investor acquisition price was $1,229,397, representing a 5.4% premium, or $63,500 more per property, than the homeowner average of $1,165,897.

This trend of investors paying a premium was not an anomaly, but a consistent pattern throughout the year. The price gap was even more pronounced in Q1 2025, when landlords paid a 12.6% premium ($152,439) over homeowners.

The data reveals significant price appreciation for investor-acquired properties. The average purchase price for landlords in 2025 ($1,277,808) marks a 12.5% increase from the average of $1,135,870 during the 2020-2023 period.

This aggressive pricing from investors suggests a highly competitive market environment where they are willing to outbid traditional buyers to secure properties, challenging the common assumption that investors primarily seek discounted assets.

The quarter-over-quarter data for 2025 shows a fluctuating but persistent premium paid by landlords: 12.6% in Q1, 5.1% in Q2, 4.5% in Q3, and 5.4% in Q4, indicating sustained competitive pressure throughout the year.

Investor activity accounted for a significant portion of the San Diego housing market in Q4 2025, with landlords purchasing 1,171 of the 3,717 total SFRs sold, a market share of 31.5%.

The purchasing landscape is overwhelmingly dominated by small-scale investors. Mom-and-pop landlords (owning 1-10 properties) acquired 1,122 homes, representing 92.9% of all investor purchases during the quarter.

In stark contrast, institutional investors with portfolios of over 1,000 properties had a negligible presence, purchasing only 3 properties, which is just 0.2% of the investor total.

The market continues to attract new participants, as evidenced by the 1,421 new landlord entities that purchased their first investment property in Q4, making up the largest single group of buyers.

These single-property landlords alone bought 924 homes, accounting for 76.5% of all properties acquired by investors, highlighting that the market's growth is fueled by new, small-scale entrants rather than large corporations.

The investor-owned housing market in San Diego County is unequivocally controlled by small-scale operators. Mom-and-pop landlords, defined as those owning 1-10 properties, hold a combined 98.7% of all investor-owned SFRs.

The scale of this dominance is most apparent in the single-property tier, where landlords owning just one rental home collectively hold 67,373 properties. This single group accounts for 84.3% of the entire investor portfolio.

Conversely, institutional investors (1,000+ properties) have a nearly non-existent footprint in the region. Their total holdings amount to just 32 properties, representing a statistically insignificant 0.0% share of the market.

This distribution debunks the narrative of a market controlled by large corporations. The data clearly shows that the rental landscape is shaped by tens of thousands of individual and small-business landlords.

The mid-size tiers also represent a small fraction of the market. Investors owning 11-1,000 properties combined hold only 1.3% of the portfolio, further emphasizing the concentration of ownership at the smallest scale.

A clear delineation exists between individual and company ownership based on portfolio size. While individuals dominate smaller portfolios, a crossover point occurs in the 6-10 property tier, where companies first achieve majority ownership at 56.4%.

For landlords just starting out, individual ownership is the prevailing structure. Individuals own 80.4% of single-property portfolios and 66.5% of two-property portfolios.

As portfolios scale, the ownership structure professionalizes. Company ownership becomes increasingly dominant, rising to 83.4% in the 11-20 property tier and 85.3% in the 21-50 property tier.

At the highest end of the market, corporate structures are nearly universal. Among large landlords holding 101-1,000 properties, companies own 132 of the 133 properties, a 99.2% share.

This pattern suggests that as investors grow their holdings beyond a handful of properties, they increasingly turn to corporate entities for liability protection, financing advantages, and operational efficiency.

Investor ownership in San Diego County is highly concentrated geographically, with the zip code 92056 leading in sheer volume with 2,464 investor-owned properties. It is followed closely by 92067 (2,371 properties) and 92057 (2,361 properties).

A different picture emerges when analyzing ownership rates. The zip code 92080 has 100.0% of its SFR properties owned by investors, indicating complete market saturation. Other areas with extremely high penetration include 92067 (79.8%), 92004 (79.0%), and 91934 (77.6%).

The data highlights a key distinction between markets with high volume and those with high penetration. For example, 92056 leads by count but has a relatively modest 15.8% ownership rate, suggesting a large overall housing stock. In contrast, 92080's 100.0% rate likely applies to a much smaller number of total homes.

The zip code 92067 stands out as a significant investor hub, ranking second for both the absolute number of investor-owned homes and the percentage of homes owned by investors. This indicates a market that is both large and deeply penetrated by investor activity.

This geographic analysis reveals distinct investor strategies, with some focusing on acquiring assets in large, diverse zip codes and others targeting smaller markets where they can achieve dominant ownership concentration.

A sharp divergence in strategy defines the San Diego market: while the overall landlord population is in a phase of strong acquisition, the largest institutional players are actively selling.

In Q4 2025, landlords as a whole were decisive net buyers, with 1,806 purchases compared to only 455 sales. This 3.97-to-1 buy-to-sell ratio signals strong confidence and a continued drive to expand portfolios.

This behavior is not a recent development. The net buyer trend for the general landlord population has been robust and consistent throughout 2025 (4.1-to-1 ratio for the full year) and 2024 (4.1-to-1 ratio).

In stark contrast, institutional investors (1,000+ tier) are in a period of divestment. In Q4, they purchased only 4 properties while selling 15, making them clear net sellers. For the full year 2025, they sold 3.6 times more properties than they bought.

This indicates a significant market shift where smaller, likely local, investors are absorbing the inventory being shed by the largest, most sophisticated players, fundamentally reshaping the ownership landscape.

Landlords were a driving force in the Q4 2025 market, participating in 1,806 of the 6,463 total SFR transactions, which translates to a 27.9% market share.

Transaction activity was heavily concentrated among the smallest investors. New, single-property landlords alone accounted for 1,453 transactions, or 80.5% of all landlord activity in the quarter.

A dramatic pricing difference between investor tiers reveals divergent acquisition strategies. The average purchase price for a new single-property landlord was $1,163,970, the highest of any tier. In contrast, institutional investors paid an average of just $583,034.

This $580,936 price difference means that institutional buyers acquired properties for 49.9% less than the newest market entrants, suggesting a focus on lower-cost assets or an ability to secure significant discounts.

Institutional investors also appear to leverage market networks more effectively. 25.0% of their Q4 purchases came from other landlords, more than double the rate of single-property landlords, who sourced only 10.7% of their acquisitions from fellow investors.
