Pima County presents a two-sided underwriting case: a published $1,483 median asking rent and 5.19% gross yield meet weakening price signals, while migration and wage evidence offers some demand support. Caution is warranted for an investor relying on resale liquidity, flood exposure, or thin post-cost cash flow; investigation should focus on whether the rent signal holds for the specific asset. Zillow county data are labeled 2026-06; FHFA’s repeat-transaction index is labeled 2025. Zillow’s median home value fell 2.1% year over year, while FHFA rose 1.11% annually. These different vintages and methods should not be averaged.
The gross yield is before operating costs and taxes. HUD’s two-bedroom FMR is $1,402, a payment standard, not an estimate of market asking rent. Property tax is 0.71%, and median annual tax is $2,272. The modeled climate-loss ratio is 0.24% of building value annually; inland flood is the dominant hazard, but the record supplies neither insurance pricing nor parcel-level loss. No expense stack, unit mix, condition, financing, or insurance quote is published, preventing a net-yield, DSCR, or cash-on-cash conclusion.
Demand evidence is supportive but not decisive. Tax-return flows show positive net migration and a $5,661 average-AGI advantage for incoming households. QCEW shows annual covered employment up 0.06% and covered-worker wages up 3.69%; Education and health services is the largest disclosed private supersector, not the whole economy. Realtor.com MLS evidence shows median listing price down 1.66% and 22.02% of listings price-reduced. Those are asking-market and seller-concession measures, not closed-sale prices or proof of buyer demand. Investor purchases represented 6.04% of total purchases, a participation measure rather than a demand forecast.
Risk limits are material. Inland-flood exposure requires parcel-level flood-zone, drainage, claims, and insurance review; the modeled ratio is not a quote. Achieved rent, vacancy, operating costs, and financing could make the gross yield insufficient. The FHFA result does not resolve Zillow’s softness, and closed-sale comparables are absent. Verify those items before relying on a rent-led case; this county record supports investigation, not a net-return conclusion.
