Industrial acquisitions in Phoenix: what buyers are underwriting in 2026
Phoenix industrial acquisitions data: $5.4B in trailing sales, 6.6% average cap rate, two named portfolio comps, and diligence math for buy-side teams.
Phoenix industrial acquisitions totaled roughly $5.4 billion in trailing 12-month sales volume as of Q4 2025, with fourth-quarter volume of $1 billion at an average of $187 per square foot, according to Matthews. The average cap rate was 6.6 percent against 12.4 percent overall vacancy, a spread that reflects lease-up risk concentrated in large-format product. Private buyers are concentrating on multi-tenant light industrial, led by BKM Capital Partners' $81.5 million purchase of a 413,000-square-foot, three-property portfolio in November 2025.
What traded, and at what pricing
Phoenix closed 2025 as one of the most active industrial sales markets in the country. Matthews' Q4 2025 Phoenix industrial report puts the buy-side picture in one view:
| Metric | Value |
|---|---|
| Trailing 12-month sales volume | $5.4B |
| Q4 2025 sales volume | $1B |
| Average price per SF (Q4) | $187 |
| Average cap rate | 6.6% |
| Overall vacancy | 12.4% |
| Under construction | 17.7M SF |
| Q4 deliveries | 5.7M SF |
| Q4 net absorption | 4.4M SF |
All figures are from Matthews' Q4 2025 Phoenix industrial report.
The pairing that defines the market is the 6.6 percent average cap rate against 12.4 percent vacancy. Capital is paying near-national pricing for a market with double-digit vacancy because the vacancy is not evenly distributed, and buyers are pricing the parts of the market where it barely exists.
The vacancy split buyers are pricing
Matthews counts approximately 87 million square feet delivered across metro Phoenix in the past three years, with nearly 90 percent of recent construction targeting buildings larger than 100,000 square feet. The result is a two-speed market: large-format vacancy runs roughly 16 percent while the overall rate sits at 12.4 percent, which means small-bay and mid-bay product is meaningfully tighter than either headline number.
Demand is not the problem. Matthews tracked 18.9 million square feet of trailing 12-month net absorption, with 4.4 million square feet in Q4 2025 alone, and asking rents of $12.99 per square foot grew 4.2 percent. The mismatch is that tenant demand skews smaller and more diverse than the big-box product the development cycle built. With 17.7 million square feet under construction, well below the recent delivery pace, Matthews expects vacancy to decline through 2026 as the pipeline thins.
For an acquisitions team, that split is the whole underwriting question. A stabilized multi-tenant park and a vacant 500,000-square-foot box can sit three miles apart and belong to different risk universes.

Two named comps from late 2025
The visible private-capital bid concentrated exactly where the vacancy math points: multi-tenant light industrial.
BKM Capital Partners paid $81.5 million for a three-property, 413,000-square-foot portfolio in November 2025, in a joint venture with Terracore Capital. The portfolio was 95 percent leased across Black Canyon Business Park (172,000 square feet, 11 buildings, Phoenix), Metro Industrial Center (120,000 square feet, 5 buildings, with suites of 1,630 to 7,650 square feet), and Twins Business Park (121,000 square feet, 2 buildings, Tempe). The price works out to roughly $197 per square foot, and the deal pushed BKM's Arizona footprint past 3.7 million square feet.
A month later, Speed Bay entered Phoenix with a $43.7 million purchase of a 228,733-square-foot, three-complex portfolio (Carleton Square, Top 10 Business Center, and Valley Commerce Center) from Top Ten Properties at $191.27 per square foot, announced December 5, 2025.
Both prints bracket the Matthews Q4 market average of $187 per square foot. That is the useful read: leased multi-tenant product trades at a modest premium to the blended market, and buyers are accepting 6-handle cap rates for rent rolls diversified across dozens of small tenants rather than one big-box lease.
The diligence load math on a portfolio deal
Phoenix's deal shape changes the operations math for a buy-side team. Placing $100 million at the Q4 2025 average of $187 per square foot means buying roughly 535,000 square feet, and in this market that usually means portfolios of multi-tenant parks rather than one or two single-tenant boxes.
Run the load on a BKM-shaped deal. Three properties multiplied by eight diligence categories (environmental, title, survey, legal, financial, physical, zoning, insurance) is 24 parallel workstreams before lease review starts. The lease review is the heavy lift: Metro Industrial Center alone runs suites of 1,630 to 7,650 square feet across 120,000 square feet, which implies somewhere between 20 and 40 leases to abstract at that one property. Across 18 buildings portfolio-wide, a 60-day DD period realistically means abstracting 60 to 100 leases, reconciling three sets of third-party reports, and tracking three title commitments toward one closing date.
Now assume the team runs two portfolio deals in diligence at once while screening new OMs, which is normal for an active Phoenix buyer. That is roughly 50 concurrent workstreams with different deadlines, owners, and document trails. Teams that manage that from an inbox and a shared drive routinely discover a missing estoppel or an unordered survey in week seven. The math says portfolio deals break in the tracking layer far more often than in the underwriting.
Running a Phoenix buy-side pipeline
The operating answer is a single system of record for the pipeline and the diligence. Every deal sits on a pipeline board with a stage and days-in-stage visible, so a deal stalled in LOI for three weeks gets asked about on Monday instead of discovered in month two. Each live deal gets a deal workspace holding the rent roll, the third-party reports, the title files, the key dates, and the lender conversations, with the DD checklist tracked item by item across all eight categories per property.
MotionCRE is built for exactly this portfolio-deal workload; see how industrial teams structure it, or the tooling breakdown in deal management software for industrial developers, which covers the same pipeline mechanics from the development side.
Screening discipline matters as much as diligence tracking. With $1 billion trading in a single quarter per Matthews, brokers are circulating product, and a written buy box (product type, suite-size profile, submarket, occupancy floor, basis ceiling) lets a team kill mismatched OMs in a 30-minute screen instead of a two-week underwriting detour.
The 2026 setup
The bull case for Phoenix industrial acquisitions rests on visible numbers: 18.9 million square feet of trailing annual absorption, a construction pipeline at 17.7 million square feet and shrinking relative to recent delivery years, rent growth of 4.2 percent, and Matthews' expectation that vacancy declines through 2026. The bear case is equally visible: Q4 deliveries of 5.7 million square feet still outran absorption of 4.4 million, and roughly 16 percent large-format vacancy takes time to clear.
Most buyers are resolving that tension the way the late-2025 comps did, by paying for diversified rent rolls in the tight segment and demanding wider pricing for big-box lease-up risk. Teams comparing Sun Belt industrial markets can see the earlier innings of the same cycle in our brief on industrial development in Houston, where the pipeline is still expanding.
Underwriting through the vacancy headline
Metro-level vacancy hides the split that matters. Big-box space built on spec carries most of the vacancy, while small and mid-bay infill product tells a tighter story, so lease-up assumptions should come from the size segment and submarket of the actual asset rather than the metro average. Water and power are the second Phoenix-specific check: both have become entitlement and expansion constraints in parts of the metro, and a tenant's growth plans can hinge on them. Buyers who segment the market this way find deals the headline number scares other bidders away from.
Whatever the thesis, the operational bar in a market trading $5.4 billion a year is the same: every deal staged, every diligence item owned, and every critical date visible to the whole team.
