Industrial Investing Fundamentals — Bulk, Last-Mile, and Light Industrial

Industrial real estate has been the best-performing CRE asset class of the last decade. Driven by e-commerce, supply chain restructuring, and manufacturing renaissance, industrial demand has outpaced supply in most US markets. Cap rates have compressed, rents have surged, and institutional capital has poured into the asset class. For active investors, industrial offers a combination of strong fundamentals, manageable operating complexity, and multiple sub-strategies.

This lesson covers industrial investing fundamentals — building specifications, tenant types, lease structures, and the major sub-categories.

Why industrial works

Before diving into the mechanics, understand why industrial has been such a strong performer.

E-commerce and supply chain drivers

Industrial demand has structural tailwinds:

• E-commerce penetration continues to grow
• Each $1B of e-commerce sales requires ~1.25M SF of warehouse (3x more than traditional retail)
• Supply chain resilience drives larger inventory positions
• Onshoring and nearshoring drive new manufacturing capacity
• Last-mile delivery drives demand for warehouses near population centers

Operational simplicity

Compared to office (constant lease rollover, tenant build-outs) or multifamily (turnover, maintenance), industrial is operationally simple:

• Long leases (5-15 years typical)
• Few tenants (often single-tenant)
• Minimal landlord build-out for many tenants
• Limited common area maintenance
• NNN structures common

A 200,000 SF industrial building with one tenant on a 10-year NNN lease is one of the simplest commercial properties to manage.

Strong tenant credit

Industrial tenants are often strong credits:

• Public companies (Amazon, FedEx, UPS, Walmart, Home Depot)
• 3PLs (XPO, Ryder, Penske)
• Major manufacturers
• Established distributors

Even smaller tenants are typically established businesses with stable operations.

Limited supply growth (until recently)

Industrial supply growth was slow for decades, lagging demand. The recent development boom has caught up with demand in many markets, but the cumulative undersupply has supported strong rent growth.

Industrial building specifications

Industrial buildings vary dramatically in specifications. Understanding what tenants want is critical.

Clear height

Definition: The vertical distance from the floor to the lowest obstruction (usually the bottom of joists or the underside of the roof structure).

Why it matters: Modern racking systems require tall clear heights. Higher clear heights mean more cubic storage per square foot.

| Clear height | Use case | |---|---| | 14-18 feet | Light industrial, older buildings, small tenants | | 22-26 feet | Modern light industrial, smaller distribution | | 28-32 feet | Modern bulk distribution | | 36-40 feet | Modern Class A bulk distribution, e-commerce | | 40+ feet | Cube storage, automated distribution |

Class A bulk distribution today is built at 36-40 foot clear height. Older 24-foot buildings are functionally obsolete for large distributors.

Loading

Dock-high doors: Doors at truck-bed height for loading trailers. Critical for distribution.

• Door count matters: more docks = faster loading
• Door spacing: standard is one dock per 10,000 SF; e-commerce wants one per 5,000 SF
• Trailer parking: yards for trailer staging

Grade-level doors: Doors at ground level for forklifts and smaller trucks. Common in light industrial and flex.

Drive-in doors: Large doors that allow vehicles to drive directly into the building. Common for service businesses.

Truck court depth

The space behind the building for trucks to maneuver:

• 130 feet is standard
• 180-200+ feet for modern distribution (allows 53-foot trailers to maneuver easily)
• Wider courts improve loading efficiency

Floor specifications

• Floor flatness for racking systems
• Floor load capacity (typical 6"-8" reinforced concrete)
• Slab thickness for heavy machinery
• Seal coating for cleanliness

Power

• Heavy power for manufacturing and food processing
• Standard power for distribution
• Three-phase power is common for industrial
• Backup generator capability for critical operations

Sprinklers

• ESFR (Early Suppression, Fast Response) sprinklers required for tall storage
• Standard wet system for lower buildings
• Pre-action systems for sensitive contents

Climate control

• Most industrial buildings: Unheated/uncooled or basic heating
• Distribution buildings: Often climate-controlled office areas
• Cold storage: Specialized refrigeration
• Pharmaceutical: Temperature and humidity control

Industrial tenant types

Different tenants have different needs.

3PL providers

Examples: XPO, Ryder, Penske, CH Robinson, DSV, Kuehne+Nagel

What they need: Modern bulk distribution, dock-heavy loading, large truck courts, flexible lease terms, room for expansion.

Lease structure: Typically 5-10 years, NNN, long-term operators.

E-commerce

Examples: Amazon, Walmart, Target, Home Depot, Wayfair, Chewy

What they need: Modern bulk distribution, last-mile facilities near population centers, automated/automation-ready buildings, high clear heights, abundant power for sortation systems.

Lease structure: 10-15 year primary, often with options. Strong credit.

Traditional retailers

Examples: Walmart, Target, Costco, Home Depot, Lowe's, regional chains

What they need: Bulk distribution for store replenishment, often near major highways and rail, large truck courts.

Lease structure: 10-25 year primary leases.

Manufacturers

Examples: Tesla, Intel, Toyota, regional manufacturers

What they need: Heavy power, specialized utilities, sometimes specialized buildings, often heavy floor loads.

Lease structure: Often own their facilities; when leased, very long terms.

Food and beverage distribution

Examples: Sysco, US Foods, PepsiCo, local distributors

What they need: Cold storage for some operations, dock-heavy loading, often 24/7 operations.

Lease structure: Long-term, often build-to-suit.

Auto industry

Examples: Auto parts distribution, dealer support, automotive logistics

What they need: Specialized buildings, often outdoor parking for vehicles, near major highways.

Construction and building materials

Examples: Lumber distributors, plumbing supply, electrical supply, HVAC distributors

What they need: Combination of warehouse and showroom, grade-level loading, sometimes outdoor storage.

Lease structure: Stable, long-term tenants.

Light manufacturing and assembly

Examples: Cabinet shops, metalworking, food processing, cosmetics

What they need: Variable building requirements, often need office space for management.

Service businesses

Examples: HVAC contractors, plumbers, electricians, landscapers

What they need: Smaller flex space with grade-level loading, often outdoor storage, easy access for service vehicles.

Major industrial sub-categories

Bulk distribution

Definition: Large warehouses (200,000+ SF, often 500,000-1,000,000+ SF) for distribution operations.

Characteristics:

• 32-40 foot clear height
• High dock count
• Large truck court (180+ feet)
• ESFR sprinklers
• Dedicated to distribution

Tenants: 3PLs, e-commerce giants, large retailers, manufacturers

Cap rates: 5.0-6.0% Class A; 5.5-7.0% Class B

Pros:

• Long leases
• Strong credit tenants
• Operationally simple
• Strong demand fundamentals

Cons:

• Capital-intensive
• Single-tenant concentration risk
• Functional obsolescence risk for older buildings

Last-mile logistics

Definition: Smaller (50,000-150,000 SF) warehouses near population centers for final-mile delivery.

Characteristics:

• 24-32 foot clear height
• Dock loading
• Locations near population (often more expensive land)
• Sometimes urban infill

Tenants: Amazon, FedEx, UPS, regional delivery services

Cap rates: 5.0-6.0%

Why it matters: Same-day and next-day delivery requires warehouses close to customers. The race for last-mile space is one of the strongest industrial trends.

Light industrial

Definition: Smaller warehouses (20,000-150,000 SF) serving local distributors, manufacturers, and contractors.

Characteristics:

• 16-28 foot clear height
• Mix of dock and grade-level doors
• Often multi-tenant
• More office finish than bulk distribution

Tenants: Local distributors, light manufacturers, contractors, service businesses

Cap rates: 5.5-7.5%

Pros:

• Lower entry cost than bulk
• Multi-tenant diversification
• Resilient demand
• Less obsolescence risk

Cons:

• More tenant management
• Smaller deal size
• More leasing activity

Light industrial is often the best entry point for active investors.

Flex / R&D space

Definition: Hybrid office-industrial buildings with significant office finish (typically 30-50% office, 50-70% warehouse).

Characteristics:

• 14-22 foot clear height
• Grade-level doors typical
• Significant office build-out
• 1-2 story typical

Tenants: Small tech companies, R&D operations, service businesses, light manufacturers, distributors

Cap rates: 6.5-8.0%

Notable: Often the most accessible industrial entry point. Multi-tenant flex centers in growing markets are popular.

IOS (Industrial Outdoor Storage)

Covered in detail in Lesson 6. Brief overview:

• Definition: Properties with paved or gravel yards for outdoor storage
• Tenants: Trucking, construction, equipment rental, container storage
• Cap rates: 6.0-8.0%
• Hot niche with limited supply

Manufacturing

Definition: Buildings designed for manufacturing operations.

Characteristics:

• Heavy power
• Specialized HVAC
• Heavy floor loads
• Specialized equipment infrastructure

Tenants: Manufacturers (often single-tenant)

Cap rates: 6.5-8.0% depending on tenant and specialization

Risk: Specialized buildings may be hard to re-tenant if the manufacturer leaves.

Cold storage

Definition: Refrigerated and frozen warehouses for food, pharmaceutical, agricultural products.

Characteristics:

• Insulation
• Refrigeration systems
• Specialized loading
• Higher build cost

Tenants: Food and beverage, pharmaceutical, agricultural

Cap rates: 6.0-7.5%

Notable: High barriers to entry. Limited supply growth.

Industrial lease structures

Industrial leases are typically NNN or modified NNN.

Triple net (NNN)

Most common industrial lease structure:

• Tenant pays base rent
• Tenant pays property taxes (or pro-rata share for multi-tenant)
• Tenant pays insurance (or pro-rata share)
• Tenant pays maintenance and repairs (or CAM for multi-tenant)
• Landlord pays roof and structure (sometimes)

The result: landlord receives net rent with minimal operating responsibility.

Modified gross / industrial gross

Some industrial leases are modified gross:

• Tenant pays base rent including some expenses
• Landlord recovers expense increases above a base year

Less common in modern industrial.

Lease term

• Bulk distribution: 7-15 year primary terms typical
• Light industrial multi-tenant: 3-7 year terms
• Single-tenant industrial: 5-15 years
• Build-to-suit: 10-25 year primary

Rent escalations

• Annual fixed increases (2-3% common)
• CPI-based (less common, unpredictable)
• Stepped increases every 5 years
• Combination structures

Tenant improvements

• Bulk distribution: Minimal landlord TI
• Light industrial: Moderate landlord TI for office build-out
• Flex space: Significant landlord TI for office finish
• Build-to-suit: Tenant or landlord builds to spec

Underwriting industrial

For an industrial acquisition:

Building analysis

• Specifications — clear height, loading, power, sprinklers
• Age and condition — when were systems last replaced?
• Functional obsolescence — does the building meet modern standards?
• Capacity for expansion — extra land for future expansion?
• Truck access — ingress/egress, queuing space

Tenant analysis

• Credit — public, private, credit reports
• Industry health
• Lease term remaining
• Renewal probability — has the tenant invested in TI? Are they growing?
• Operations at this location — is this a critical facility for them?

Market analysis

• Submarket vacancy — current and trend
• New supply pipeline — what's being built
• Net absorption
• Rent growth
• Distance to highways, ports, rail
• Access to labor force

Financial underwriting

Year 1:

• In-place rent (verified by lease)
• NNN reimbursements (per lease)
• Vacancy assumption (low for stabilized industrial, 2-5%)
• Operating expenses (mostly reimbursed)
• NOI

Years 2-5:

• Rent escalations per lease
• Renewal assumptions
• Capex schedule
• Refresh capex for re-leasing

Year 5 sale:

• Exit cap rate (similar to going-in for stable markets)
• Sale costs
• Loan payoff

Cap rate by sub-type

| Type | Typical cap rate | |---|---| | Class A bulk distribution, prime market | 4.5-5.5% | | Class A bulk distribution, secondary market | 5.0-6.0% | | Class B distribution | 5.5-6.5% | | Last-mile logistics | 5.0-6.0% | | Light industrial multi-tenant | 6.0-7.5% | | Manufacturing single tenant | 6.5-8.0% | | Flex / R&D | 6.5-8.0% | | IOS | 6.0-8.0% | | Cold storage | 6.0-7.5% |

Worked example: Central Florida light industrial

You're considering a 75,000 SF multi-tenant light industrial building in Lakeland, FL.

Property facts

• Size: 75,000 SF, 6 tenants
• Built: 2005
• Clear height: 22 feet
• Loading: 2 dock doors per tenant + grade-level doors
• Tenants: Cabinet maker (15K SF), HVAC contractor (12K SF), plumbing supply (15K SF), small distributor (10K SF), auto parts (10K SF), one vacant unit (13K SF)
• In-place rent: $9.50/SF NNN average
• Market rent: $12/SF NNN
• Occupancy: 83% (one vacant unit)
• Asking price: $7.5M
• Going-in cap rate: 6.8%
• Year 1 NOI (current): $510K

Underwriting plan

• Lease vacant 13,000 SF at $12/SF: +$156K
• Push rents at 3 lease rollovers in 18 months: +$45K
• Maintain quality and tenant relationships
• Year 3 NOI: $711K

Year 5 exit

• 6.5% exit cap → $10.9M sale price
• Sale costs and loan payoff
• Equity multiple ~1.8x
• IRR ~16-18%

Why it works

• Below-market rents at acquisition
• Vacant space ready to lease at market
• Stable Lakeland market with strong industrial demand
• Operationally simple (multi-tenant but limited turnover expected)
• Path to exit at compressed cap rate

This is a representative active-investor light industrial deal. Multi-tenant flex and light industrial are excellent entry points.

Common industrial mistakes

1. Buying buildings with functional obsolescence (low clear height, inadequate power, poor loading)
2. Single-tenant concentration without strong credit
3. Ignoring market vacancy and supply pipeline
4. Underestimating capex for older buildings
5. Overpaying based on aggressive rent growth assumptions
6. Missing trade area dynamics (port traffic, highway access)
7. Buying specialized buildings without re-tenancy plan
8. Ignoring labor market for tenant operations

What to take away

• Industrial has been the best-performing CRE asset class of the last decade
• Sub-categories: bulk distribution, last-mile, light industrial, flex, IOS, manufacturing, cold storage
• Building specifications matter — clear height, loading, power, sprinklers determine functional value
• Lease structures are typically NNN with long primary terms
• Tenant credit ranges from investment-grade to small business; underwrite each
• Cap rates: 4.5-5.5% Class A bulk; 6-7% light industrial; 6-8% specialty types
• Light industrial multi-tenant is often the best entry point for active investors
• Florida industrial has strong fundamentals driven by population, ports, and tourism
• Underwrite carefully: tenant credit, building functional quality, market dynamics
• Avoid functional obsolescence and weak markets
