Worked Example: West Valley Logistics Warehouse Scenario (110,000 RSF)
Evaluating an illustrative 110,000 RSF distribution warehouse in the Glendale / Loop 303 corridor on an NNN lease:
- Purchase Price: $15,400,000 ($140.00 / RSF)
- Contractual Base Rent: $8.75 / RSF NNN = $962,500 / year
- Vacancy Allowance & Structural Roof/HVAC Reserves: -$38,500 / year
- Stabilized Net Operating Income (NOI): $924,000 → Unleveraged Cap Rate = $924,000 ÷ $15,400,000 = 6.00%
Underwriting Takeaway: At an illustrative 6.00% Unleveraged Cap Rate, underwriters still verify tenant creditworthiness, electrical load specifications, and replacement reserves for rooftop package cooling units exposed to extreme summer heat.
Phoenix Underwriting Risks & Due Diligence Considerations
- Water allocation rules and electrical utility capacity require site-specific verification for industrial developments.
- Extreme summer temperatures shorten rooftop HVAC lifespans and increase common-area electricity expenses.

Phoenix Commercial Real Estate FAQs
Are the Phoenix cap rate ranges on this page live market quotes?
No. All cap rate ranges and worked examples on this page are illustrative underwriting assumptions for educational financial modeling. Always verify local comparable sales in Maricopa County.
What special CapEx reserves should be modeled for Phoenix commercial properties?
Because summer temperatures regularly exceed 110°F, rooftop HVAC units and Elastomeric roof coatings experience accelerated wear, requiring conservative annual capital replacement reserves.
How does Arizona property tax assessment work for commercial real estate?
Arizona uses a dual-value system (Full Cash Value and Limited Property Value, with statutory assessment ratios by property class). Always verify Maricopa County Assessor classifications during due diligence.
