Industrial Asset Taxonomy

Asset Type Overview

---

1. Big Box / Bulk Distribution

The institutional core of the modern industrial sector. Purpose-built for regional and national supply chain operations.

Defining characteristics:

• 500K–1M+ SF on a single footprint
• 36'–40'+ clear height (Class A 2026 standard is 40'+)
• 100–300+ dock doors; 120'+ truck court depth
• Single or limited tenancy
• Sites of 30–80+ acres; 35–45% lot coverage

Tenant universe: Amazon, Walmart, Target, Home Depot, major 3PLs (Prologis tenants, DHL, XPO), CPG distributors, auto parts

Underwriting note: Lease structures are NNN or absolute NNN. Rent growth in 2021–2024 was driven by e-commerce absorption. In 2026, bulk distribution vacancy has risen in Sunbelt markets (DFW, Phoenix, Las Vegas) due to oversupply; underwriting must model 18–24 month lease-up for speculative product.

2. Last-Mile / Urban Infill

Small-bay, high-density logistics facilities serving same-day and next-day delivery into dense urban populations. Scarcity of infill land is the primary value driver.

Defining characteristics:

• 50K–250K SF; often multi-story in land-constrained markets
• 24'–32' clear height
• High dock count relative to building size (1 per 3,000–5,000 SF)
• Located inside or adjacent to urban core, often on repurposed retail or industrial land

Tenant universe: Amazon last-mile hubs, UPS/FedEx, grocery delivery, meal kit operators, dark kitchens, local e-commerce brands

Underwriting note: Urban infill industrial commands a 25–75 bps cap rate premium over comparable suburban bulk product in constrained markets. Lease rates are 20–40% higher per SF than comparable bulk. Multi-story last-mile (proven in NYC, Seattle, and Tokyo) is still nascent in Texas markets.

---

3. Multi-Tenant / Shallow Bay

The "small business" end of industrial. Serves local and regional tenants who need modest warehouse/flex space without the capital commitment of a full-building lease.

Defining characteristics:

• Individual units 5,000–50,000 SF
• 18'–28' clear height (below Class A standards)
• Mix of dock-high and grade-level doors
• High tenant count; shorter lease terms (2–5 years)

Underwriting note: Multi-tenant industrial offers higher initial yields than single-tenant net-lease but requires active management. Retention assumptions of 65–75% are the institutional standard. Rollover exposure in any single year above 40% of total NRA is a lease-up risk flag.

---

4. Flex / R&D

A hybrid property type that splits square footage between climate-controlled office, lab, or showroom and functional warehouse. Historically underwritten as "business park" product.

Defining characteristics:

• Office finish ratio 15–40% of total SF
• Clear heights 14'–24'; below bulk distribution requirements
• Grade-level doors with occasional dock-high
• Campus or park settings common

Tenant universe: Tech companies, defense contractors, electronics manufacturers, life sciences tenants in early growth stage, medical device companies

Underwriting note: Flex vacancy is elevated nationally in 2026 due to the remote work overhang reducing demand for the office component. Re-purposing the office finish back to pure warehouse is a value-add thesis on well-located flex product with adequate clear height.

---

5. Cold Storage / Temperature-Controlled

Purpose-built or converted facilities designed to maintain specific temperature ranges for food, pharmaceutical, and specialty goods storage.

Defining characteristics:

• Insulated panels, refrigeration systems, and controlled atmosphere zones
• Temperatures range from +55°F (produce) to −20°F (frozen food)
• Higher construction cost: $150–$250/SF vs. $75–$120/SF for ambient warehouse
• High power demand (250–600 kW per 10,000 SF)
• 40'+ clear height for high-bay automated racking

Underwriting note: Cold storage assets trade at 50–100 bps tighter cap rates than comparable ambient industrial in most markets due to scarcity. Tenant replacement risk is higher because cold storage fit-out is proprietary and conversion back to ambient is expensive. Remaining useful life of refrigeration equipment is a key PCA item.

---

6. Industrial Outdoor Storage (IOS)

Land-intensive logistics use: storage of trailers, containers, construction materials, equipment, vehicles, and similar assets on improved or semi-improved land.

Defining characteristics:

• Primarily land value — minimal or no permanent structure
• Paved, fenced, and lit; may include a small office/maintenance building
• High barriers to entry in infill markets (zoning, environmental, community opposition)
• Lease structures are typically NNN month-to-month or annual; rarely long-term

Revenue benchmarks (2026):

• DFW and Houston: $5,500–$6,000/acre/month
• Phoenix, Southern California: $6,000–$9,000/acre/month
• Land-only acquisitions underwritten at 6–7% going-in yields on current rents

Underwriting note: IOS has emerged as a standalone institutional asset class since 2021. The combination of land scarcity, low management intensity, and essential-use tenancy has attracted core and core-plus capital. The Terminal Logistics / Center Capital profile supports the platform-formation read, but its sponsored-content market statistics should remain attributed until primary datasets are preserved. Key risk is zoning vulnerability — entitlements may not survive a rezoning challenge in suburban municipalities. See Source: Terminal Logistics IOS Platform 2026.

7. Data Center

Specialized facilities providing physical infrastructure (power, cooling, connectivity) for computing equipment. Distinct from conventional industrial in virtually every underwriting dimension.

Defining characteristics:

• Critical metrics: power capacity (MW), power density (kW per rack), PUE (Power Usage Effectiveness), redundancy tier (I–IV)
• Shell and core value is minimal; tenant-installed equipment is the value
• Lease structures: triple-net, often 10–20 year terms, power-based rent structures ($X per kW/month)
• Enormous power demand: hyperscale facilities consume 100–500+ MW

Underwriting note: Data center underwriting requires specialized expertise in power procurement, cooling systems, and connectivity infrastructure. Cap rates for data centers trail all other industrial sub-types at 4.0–5.5% for stabilized product. AI-driven demand has created severe capacity shortages in primary markets (NOVA, Dallas/Fort Worth, Chicago, Phoenix) in 2025–2026.

---

8. Life Sciences / Lab

Wet lab, cleanroom, pharmaceutical manufacturing, and GMP (Good Manufacturing Practices) facilities. High fit-out cost, specialized tenant requirements.

Defining characteristics:

• Enhanced HVAC for fume extraction and air changes
• Slab load requirements for heavy equipment
• Specialty electrical (single-phase 120V and three-phase power to lab benches)
• Often co-located in campus environments adjacent to research universities or medical centers

Underwriting note: Life sciences real estate outperformed all other property types in 2021–2022. Correction in 2023–2024 was sharp — venture funding contraction reduced lab demand; vacancy rose in secondary clusters. In 2026, Boston, San Diego, and the San Francisco Bay Area remain undersupplied; Austin, RTP, and Houston Medical Center are growth-stage clusters with elevated near-term risk.

---

9. 3PL / Contract Logistics

Third-party logistics operators (3PLs) lease bulk distribution facilities on behalf of their end-user clients. The underwriting dynamic differs from direct-tenant leases because the 3PL is the credit but the real demand driver is the 3PL's underlying client relationship.

Key 3PL tenants: DHL Supply Chain, Ryder, XPO Logistics, Kuehne+Nagel, GXO Logistics, DSC Logistics

Underwriting note: 3PL leases often have shorter terms (3–5 years) than comparable direct-user leases because 3PL contracts with end-users are similarly short. Rollover risk is higher; retention assumptions of 60–70% are more appropriate than the 75–80% benchmark for direct users. The 3PL credit profile matters — some 3PLs are investment-grade; others are not.

Valuation and Cap Rate Hierarchy (2026)

From most to least compressed cap rates in Texas institutional markets:

1. Data Center (4.0–5.0%)
2. Cold Storage (5.0–5.75%)
3. IOS (5.5–6.5%)
4. Last-Mile Urban Infill (5.25–6.0%)
5. Big Box Bulk — Single-Tenant NNN (5.5–6.5%)
6. Multi-Tenant Shallow Bay (5.75–6.75%)
7. Flex/R&D (6.5–8.0%)
8. Life Sciences (variable — 5.0–7.5% depending on market and lease structure)

---

Subtype Cap-Rate Drivers

The hierarchy above should not be used as a shortcut. Each industrial subtype has a different numerator driver and denominator risk. Use Industrial Valuation and Probability-Weighted Underwriting to reconcile market extraction, build-up, Gordon, BOI, and DCF-implied cap-rate evidence.

Cap-rate assessment begins with the subtype comp set. Adjustments for tenant credit, WALT, location, physical specs, environmental risk, and exit buyer pool are then layered explicitly rather than hidden inside a generic "industrial" cap rate.

Critical Minerals Manufacturing: Vulcan Elements Rare-Earth Magnet Plant, Benson NC (April 2026)

The April 10, 2026 article reports Vulcan Elements' $8M purchase of 56 acres at Crosspoint Logistics Center in Benson, NC, for a planned $918M rare-earth magnet facility, up to 1,000 jobs, and operations targeted for 2027. The source note qualifies the article's $1.4B defense-contract description: the company's original announcement describes a financing partnership with pending diligence, not a procurement commitment. See Source: Rare-Earth Magnet Maker to Construct $918M Raleigh-Area Plant.

This is a case for defense-adjacent critical minerals manufacturing, with specialized process, power, and commissioning requirements. A financing partnership does not give the occupant government-tenant credit or guarantee long-duration demand. CRET hypothesis: Completed capacity could anchor a supplier cluster; test executed offtake, production milestones, counterparty credit, local supplier leases, security requirements, and re-tenanting costs before assigning rent or exit-cap credit.
