County-Wide Gross Yield: A Starting Point, Not a Conclusion

At $343,106 median price and $1,483/month median rent, Pima County produces a gross yield of 5.19% on an aggregate basis. That number is arithmetically correct and functionally incomplete. It blends a downtown historic property at $512,000 with a Rita Ranch single-family at or below the county median, a duplex near the University of Arizona with a suburban Oro Valley home, and every asset class in between. The spread between those sub-markets is where the real underwriting happens.

The county-wide figure does, however, confirm one thing: Pima County is a cash-flow market, not a speculative equity market. With home prices down 2.1% year-over-year and Zillow forecasting only +0.6% through September 2026, the capital-gains thesis is weak. Investors buying here today are buying for current yield, which means the 5.19% gross yield is a floor to improve upon through submarket selection and asset configuration, not a number to accept at face value.

Neighborhood and Segment Breakdown

Downtown Tucson and West University: Premium Neighborhoods, Compressed Gross Yields

Armory Park, listed on the National Register of Historic Places, posts a median sale price of about $512,000. At the county median rent of $1,483/month, a gross yield on that acquisition sits around 3.47%. Even if rents in the West University and downtown corridor run 15–20% above the county median (consistent with walkability and proximity to the University of Arizona driving demand from students and young professionals), you are working with gross yields in the 4.0–4.2% range before any expense load.

These neighborhoods are appropriate for renovation-driven value-add strategies where forced appreciation closes the yield gap, not for stabilized income plays at current acquisition prices. Investors entering at $512,000 must underwrite displacement risk and community opposition in gentrifying corridors alongside the higher basis.

Oro Valley: Stable Family Demand, Post-Peak Price Trajectory

Oro Valley outperformed the broader county with 5.8% appreciation in 2024, then gave back 0.8% year-to-date through 2025. That trajectory mirrors the county-wide story: prices ran ahead of fundamentals during the pandemic cycle and are now normalizing. At prices above the county median (Oro Valley's 2024 outperformance implies a higher price point), gross yields here run below the 5.19% county average, likely in the 4.5–4.8% range depending on specific acquisition price.

The durable rental case here rests on school quality (Vail School District in Rita Ranch; top-rated district), which translates into stable family-renter demand and lower turnover risk. Lower turnover improves net yield even when gross yield looks modest, because vacancy and re-leasing costs are a real drag on NOI.

Rita Ranch and Southeast Tucson: Workforce Single-Family, Closest to the Aggregate

Rita Ranch sits within the Vail School District and features newer residential development, placing it closest to the county median price point. This is the submarket where the 5.19% gross yield is most representative. Family renters in newer-construction suburbs have fewer alternatives to single-family rentals than tenants in urban core or student corridors, providing steady demand. New residential land sales surged 22% year-to-date through April 2025, signaling continued builder activity in suburban Tucson. That is a competition risk for existing operators when new product delivers.

Small Multifamily and Value-Add: Duplex and Triplex Creation

The most direct route to above-market gross yields in Pima County is the zoning change the county adopted in September 2024. Duplexes and triplexes are now permitted as-of-right in all rural and residential zones (excluding the TH zone), and Arizona HB 2928, signed May 23, 2025, mandates ADU permissibility on all residentially zoned single-family parcels. At least one attached and one detached ADU must be permitted per single-family lot, with a third unit available on parcels of one acre or more if income-restricted.

The arithmetic is straightforward: if a single-family acquisition at $343,106 grosses 5.19%, adding a detached ADU that rents at even $900/month lifts the gross yield to about 8.3% on the same acquisition basis. That assumes no ADU construction cost, which is unrealistic, but a $100,000 ADU build on a $343,106 acquisition at combined rents of $2,383/month (original unit plus ADU) produces a gross yield of about 6.5% on total invested capital. That is well above the 5.19% baseline and the primary path to equity-and-income upside in this market right now.

Property Tax Impact on Net Cap Rates

Pima County's effective property tax rate averages 0.85% of market value, generating a median annual tax bill of about $2,206 on the $343,106 median-priced property. At a 5.19% gross yield, that property generates $17,796/year in gross rent. The $2,206 tax bill represents about 12.4% of gross rent, or roughly 124 basis points of gross yield lost to property tax alone, before insurance, maintenance, vacancy, and management.

Compared to a national median effective rate of 1.02%, Pima County investors save about $581/year in property tax on a median-priced asset. That translates to about 20 basis points of additional net yield retained versus a national-average-tax market. On a $512,000 Armory Park acquisition, the 0.85% rate produces a tax bill of about $4,352/year, consuming about 242 basis points of a gross yield that (generously) starts around 4.1%.

Arizona's 5% annual cap on Limited Property Value (LPV) increases removes one underwriting uncertainty: even in a scenario where county values recover sharply, tax escalation on a held asset cannot exceed 5% per year. That predictability is worth pricing into a long-term hold model.

Cap Rate Compression vs. Decompression

Home prices declined 2.1% year-over-year through mid-2026. Apartment supply from Tucson's 2021–2022 construction peak has slowed, and reporting from the Tucson Arizona Daily Star indicates rent increases are expected beginning in 2026 as the supply pipeline tightens against growing demand. Average weekly wages grew 3.5% year-over-year in Q3 2025 to $1,195/week, which supports renter ability to absorb moderate rent increases.

When rents rise and prices are flat-to-declining, cap rates decompress. That is the direction Pima County is moving. Investors who acquire at current prices stand to benefit from improving net yields over a 12–36 month hold horizon, not from price appreciation. The risk to this scenario is the 48% month-over-month rise in active listings seen in April 2025 continuing long enough to create pricing pressure that offsets rent growth.

Flood Insurance Adjustment to Net Yield

FEMA finalized updated Flood Insurance Rate Maps for Pima County covering the Santa Cruz River, Sabino Creek, Cienega Creek, Bear Creek, and the Oro Valley/La Cholla Wash corridors in April 2026. Properties reclassified into Special Flood Hazard Areas require flood insurance on federally backed mortgages, adding an operating cost line that directly reduces NOI.

The partial offset: Pima County's Regional Flood Control District holds a Class-2 Community Rating System rating as of April 1, 2024, qualifying property owners in unincorporated Pima County for up to a 40% discount on NFIP premiums. An NFIP policy that would otherwise run $2,000–$2,500/year costs $1,200–$1,500 after the Class-2 discount, reducing the net yield drag. Investors acquiring in riverine corridors should verify whether a specific parcel sits in unincorporated Pima County (CRS discount applies) versus city limits, and should pull the updated FIRM panel before closing.

Neighborhood Comparison

Cap Rate Outlook

Three converging factors point to net yield improvement over the next two to four years. First, the supply pipeline is thinning: fewer apartments under construction as of early 2026 against a population of over 1 million creates upward pressure on rents. Second, the Stone Avenue BRT corridor (federal grant anticipated Fall 2027, construction through 2030) will price transit proximity into acquisitions made now at pre-infrastructure values. Properties within walkable distance of the Stone Avenue alignment currently trade at no premium; that changes as the $137.1 million project moves through construction. Third, the ADU and duplex/triplex zoning reforms give existing owners a legal, ministerial path to add income units without discretionary approvals.

The base case is modest price appreciation of 2–4% through 2026 per Houzeo projections, improving rent growth as supply tightens, and stable tax burdens held in check by the LPV cap. That combination produces net cap rate expansion for patient buyers who acquire now in a balanced-to-buyer-leaning market where active listings rose 48% in a single month and sellers are negotiating.
