Pima (AZ) Investor Pulse Report (2025-Q4)

Investors have a significant footprint in Pima County, owning 54,752 single-family residential properties, which constitutes 19.5% of the total market of 280,288 SFRs.

The ownership landscape is overwhelmingly composed of individual investors, who own 44,282 properties. This represents an 80.9% share of the investor market, dwarfing the 12,991 properties (23.7% share) held by companies.

By entity count, the market skews even more heavily toward individuals. There are 61,383 individual landlords compared to just 7,429 company landlords, an 8-to-1 ratio that highlights the fragmented, small-scale nature of property investment in the region.

The portfolio's purpose is clear, with 98.0% of all investor-owned properties (53,670) classified as rented. This near-universal application as rental housing underscores the role these properties play in the local housing supply.

Investors in Pima County employ a balanced mix of financing strategies. The portfolio is nearly evenly divided between financed properties (28,116) and those owned outright with cash (26,636), indicating diverse capitalization approaches among landlords.

Landlords in Pima County consistently acquire properties at a lower cost than traditional homebuyers. In Q4 2025, the average landlord purchase price was $458,798, a 3.3% discount compared to the homeowner average of $474,396, which translates to a $15,598 savings per home.

The size of this discount fluctuated significantly throughout 2025, starting at a negligible 0.0% in Q1 ($186), expanding to a substantial 4.9% in Q3 ($22,982), and then settling at 3.3% in the final quarter. This volatility suggests changing market conditions or deal-sourcing opportunities.

Despite recent fluctuations, property values have seen strong long-term growth. The Q4 2025 average acquisition price of $458,798 for landlords is a 12.2% increase over the $408,862 average from the 2020-2023 pandemic era.

However, a year-over-year comparison indicates a potential market cooling. The Q4 2025 landlord price is notably lower than the $482,521 average seen in Q4 2024, signaling a moderation in price growth for investment properties.

Within 2025, landlord prices dipped in Q3 to $444,819 before a modest recovery in Q4. This movement suggests investors may be capitalizing on periodic price softness in the market.

Landlords represented a major force in the Pima County real estate market in Q4 2025, acquiring 1,000 of the 2,937 total SFR properties sold, which amounts to a 34.0% market share of all purchases.

The overwhelming majority of this purchasing activity came from small-scale investors. Mom-and-pop landlords (Tiers 01-04) were responsible for 89.1% of all properties bought by investors during the quarter.

A massive wave of new investors entered the market, with 1,166 new single-property landlord entities making purchases. This group alone acquired 770 properties, accounting for 74.5% of all investor acquisitions and signaling strong grassroots interest in real estate investment.

Institutional buyers (1,000+ properties) had a minimal impact on the purchasing landscape, acquiring just 9 properties. This represents only 0.9% of the total landlord purchase volume, challenging the narrative of large corporations dominating acquisitions.

Mid-size investors (11-1,000 properties) filled the space between the two extremes, collectively purchasing 113 properties and accounting for 10.9% of landlord buying activity in Q4.

The investor landscape in Pima County is definitively controlled by small-scale operators. Landlords owning 1-10 properties, commonly known as 'mom-and-pops', hold a combined 91.1% of all investor-owned SFRs.

The single-property landlord tier forms the bedrock of the market, owning 42,338 properties. This single group accounts for 74.8% of the entire investor portfolio, highlighting extreme fragmentation and a low barrier to entry.

Contrary to common narratives, institutional investors (1,000+ properties) have a very limited footprint. They own just 1,603 properties, which equates to a mere 2.8% of the total investor-owned housing stock in the county.

The seven tiers of landlords owning between 1 and 100 properties collectively control 94.1% of the investor market, showing that ownership concentration only begins at a very large scale.

This distribution reveals a market built on a broad base of individual and small-business participation rather than one dominated by a few large corporate entities, with 74.8% of the portfolio held by the smallest possible investor type.

A distinct crossover point in ownership structure occurs as portfolios scale. While individuals dominate smaller tiers, companies become the majority owners (52.2%) starting in the 6-10 property tier, indicating a common threshold for incorporation.

The entry-level tiers are fundamentally driven by individuals. They own 87.1% of single-property portfolios (38,510 properties) and 76.8% of two-property portfolios (3,093 properties).

Company ownership becomes nearly absolute at larger scales. In the 21-50 property tier, companies own 93.6% of assets, a figure that remains above 90% for all subsequent tiers with available data.

This pattern shows a clear professionalization trajectory: investors begin as individuals and transition to corporate entities to manage the legal and financial complexities of larger portfolios.

Even within the 101-1,000 property tier, a small contingent of 185 properties (10.5%) remains under individual ownership, suggesting that while uncommon, it is possible to manage larger portfolios without incorporating.

Investor ownership in Pima County is not evenly distributed but is instead concentrated in specific geographic pockets. The top five zip codes by property count (85719, 85614, 85711, 85745, and 85710) collectively hold 11,322 investor-owned SFRs.

The zip code 85719 stands out as the area with the single highest volume of investor properties, containing 2,515 landlord-owned homes.

A key finding is the distinction between high-volume and high-saturation areas. While 85719 leads in count, its investor ownership rate is 32.8%. In contrast, zip code 85601 has the highest concentration, with 74.5% of its homes owned by investors.

Several other zip codes show extremely high investor penetration rates, including 85619 (68.0%) and 85654 (65.4%). These areas represent markets that are fundamentally defined by rental housing.

This geographical divergence suggests investors are pursuing different strategies. Some target larger, more populous zip codes for scale, while others focus on smaller communities where they can achieve significant market share and pricing power.

The overall investor market in Pima County is in a period of aggressive expansion, with landlords acting as strong net buyers. In Q4 2025, they purchased 1,487 properties while selling only 309, a buy-to-sell ratio of 4.8 to 1.

This net buying trend has been consistent, with landlords purchasing 6,225 properties and selling 1,307 for the full year 2025, following an even more active 2024 where they bought 8,947 properties.

A starkly different pattern emerges for institutional investors (1,000+ properties), who are actively divesting. In Q4, they were net sellers, selling 29 properties and buying only 10. This trend holds for the full year 2025, with 73 sales versus only 67 acquisitions.

The institutional behavior in 2025 marks a strategic reversal from 2024, when they were slight net buyers (68 buys vs. 60 sells). This shift from accumulation to divestment signals a change in their outlook on the Pima County market.

The divergence is critical: while smaller, local investors continue to accumulate properties at a rapid pace, the largest, most sophisticated players are reducing their exposure, creating a clear split in market sentiment and strategy.

Investors were a primary driver of market activity in Q4, participating in 1,487 of the 4,752 total SFR transactions. This gives landlords a significant 31.3% share of all transaction activity in Pima County.

A dramatic pricing disparity exists between the smallest and largest investors. Single-property landlords paid the most, at an average of $459,706, while institutional investors paid the least, at $299,953. This represents a 34.8% discount for the largest players.

The transaction volume was dominated by mom-and-pop landlords (Tiers 01-04), who were responsible for 1,365 transactions (91.8% of the landlord total). Institutional investors, by contrast, conducted only 10 transactions.

Acquisition strategies also differ by tier. Institutional investors sourced 30.0% of their new properties from other landlords, suggesting a focus on acquiring existing, cash-flowing rental assets. This was the highest rate of any tier.

Conversely, new single-property landlords sourced only 8.8% of their purchases from other landlords, indicating they primarily compete with traditional homebuyers for properties on the open market.
