Introduction
A modern distribution warehouse is close to a commodity. Two 500,000-square-foot big-box facilities a few miles apart in the same Sun Belt submarket, both with 36-foot clear heights, the same dock-door ratios, and the same year of construction, are nearly interchangeable as physical assets. What is not interchangeable is the lease that sits on top of the slab. When the box itself is generic, value migrates to the contract, and the most important line in that contract is the name of the tenant signing it. This is why an Amazon-leased warehouse can be worth tens of millions of dollars more than a physically identical building leased to an unrated logistics operator.
Industrial real estate is dominated by the NNN triple-net lease structure, in which the tenant absorbs property taxes, building insurance, and maintenance on top of base rent. NNN is the standard for big-box distribution, manufacturing, and most institutional industrial product; smaller variations (modified gross, single and double net) appear in specific sub-segments, but the triple-net convention drives the vast majority of institutional industrial lease economics. The result is predictable landlord net cash flow, because operating-cost variability flows through to the tenant rather than the landlord, and that predictability is what supports the tight cap rates industrial commands relative to other property sectors. Terms run from 5 to 7 years for last-mile logistics and small-tenant deals out to 10 to 15-plus years for big-box distribution with major investment-grade tenants such as Amazon, Walmart, Target, Home Depot, and Costco. This article is specifically about how that structure works in industrial and logistics product; the broader treatment of gross, net, NNN, and ground leases across all property types lives separately.
The NNN Industrial Lease Standard
The NNN convention in industrial means the tenant pays base rent plus three categories of operating expenses: property taxes (typically billed monthly based on the assessed value and applicable mill rates), building insurance (including property and liability coverage that the tenant procures and pays directly), and maintenance (covering structural maintenance, roof, HVAC, parking lot, and common-area items). Additional CAM (Common Area Maintenance) charges may apply for multi-tenant properties to cover shared facility costs like exterior lighting, landscaping, and security.
The economic result for the landlord: base rent dollars flow nearly fully to NOI without operating expense leakage. A 100,000 sqft industrial property leased at $8/sqft NNN produces approximately $800,000 of base rent and ~$750,000 of NOI (after accounting for non-recoverable landlord expenses like management fees and capital reserves); the same property leased at $11/sqft gross would produce similar net economics after the landlord absorbs the operating cost burden. The NNN structure removes operating-cost-pass-through complexity and produces cleaner forward cash flow projections.
| Lease Structure | Tenant Pays | Landlord Pays | Typical Industrial Use |
|---|---|---|---|
| NNN (Triple Net) | Base rent + property tax + insurance + maintenance | Structural items, capital improvements | Standard for big-box and most institutional industrial |
| NN (Double Net) | Base rent + property tax + insurance | Maintenance + capital | Less common, some industrial flex |
| N (Single Net) | Base rent + property tax | Insurance + maintenance + capital | Rare in institutional industrial |
| Modified Gross | Base rent + some operating costs | Base operating costs + capital | Some flex industrial and small-bay |
| Full Gross | Base rent only | All operating costs | Rare in industrial |
- Triple Net (NNN) Lease (Industrial)
The standard industrial lease structure in which the tenant absorbs property taxes, building insurance, and maintenance on top of base rent, leaving the landlord with primarily structural and capital responsibilities. The structure produces predictable forward landlord cash flow because operating cost variability flows through to the tenant, and supports the tight cap rates that institutional industrial commands. NNN dominates institutional industrial leasing; gross-lease structures are largely confined to small-bay flex and certain specialty product types. NNN lease terms in industrial range from 3-5 years for smaller tenants to 10-15+ years for major investment-grade big-box tenants.
Lease Term Variation by Sub-Segment
Lease terms vary meaningfully by sub-segment and tenant profile:
- Big-box distribution (150K+ sqft) with investment-grade tenant: typical lease term 10-15+ years, with multiple renewal options at predetermined or fair-market rents. The long duration reflects both the tenant's operational integration with the specific facility (build-out customization, supply chain configuration) and the landlord's preference for stable long-duration income at the tight cap rates these deals command.
- Big-box distribution with smaller or sub-IG tenant: typical 7-10 year initial term, often with shorter renewal options.
- Mid-bay and last-mile (50K-150K sqft): typical 5-7 year initial terms, reflecting the tenant universe's broader credit mix and shorter operational planning horizons.
- Small-bay and flex industrial (under 50K sqft): typical 3-5 year initial terms with frequent renewal cycles.
- Manufacturing and specialty industrial: variable lease terms tied to specific tenant operations; can range from short-duration to 20+ year deals with significant landlord capex contributions.
The lease term variation directly influences forward NOI predictability and cap rate selection. Long-duration leases with strong-credit tenants approach bond-like cash flows and command the tightest cap rates; shorter-duration leases with mixed-credit tenants carry more rollover risk and trade at wider cap rates.
Rent Escalations Are a Primary Value Lever
Inside the term, the single most important economic clause after the starting rent is the annual escalation, the fixed percentage by which rent steps up each year. Industrial escalations historically sat around 2 to 3 percent, but the demand surge and high inflation of the early 2020s pushed new leases higher, and 3 to 4 percent fixed annual bumps are now common, with some markets striking deals at 4 percent or above. A minority of leases tie escalations to CPI or to a periodic fair-market-rent reset rather than a fixed step.
The escalation rate is easy to treat as a footnote and expensive to ignore, because it compounds. On a 10-year lease, a 3 percent annual bump leaves the tenant paying roughly 30 percent more in the final year than the first; a 4 percent bump pushes that to roughly 42 percent. That gap, on two otherwise identical buildings, changes the going-in yield a buyer will accept, the terminal value at exit, and how much debt the asset can carry. Underwriting that models flat rent through the term, or that copies a 3 percent assumption onto a lease that actually escalates at 2.5 percent, mis-prices the asset before the credit question is even reached.
How Clear Height and Spec Turn the Box Into a Commodity
The reason value concentrates in the lease rather than the building is that modern industrial product is increasingly standardized. Functional clear height, the unobstructed vertical distance from floor to the lowest overhead obstruction, is the spec that matters most, because pallet racking and automated storage systems exploit vertical cube. Bulk distribution settled on 28 to 32-foot clear heights through the 2000s and 2010s; the current benchmark for new Class A development is 32 to 36 feet, and large e-commerce and automated facilities increasingly reach 40 feet or more to support multi-level mezzanines and shuttle systems.
Around that clear-height spine cluster the rest of the standardized features: dock-door ratios scaled to throughput, deep truck courts and trailer-parking ratios, large column spacing, and heavy floor-load capacity. When a developer can deliver any of these to the same modern standard, the buildings converge, and tenants choose on location, rent, and availability rather than on the architecture. That convergence is exactly what makes the tenant covenant the differentiator. A building that any competent merchant builder can replicate carries little scarcity value on its own; a 12-year lease to an investment-grade tenant on that building is far harder to reproduce.
Tenant Credit and Cap Rate Implications
Tenant credit is one of the largest single drivers of industrial property valuation, because it flows straight into the cap rate the market will accept. The stronger the credit, the more certain the income, and the lower the cap rate, which is why two physically identical buildings can carry very different values. The standard cap rate distinction:
- Investment-grade tenant (BBB-/Baa3 or better S&P/Moody's rating): commands cap rates 50-150 basis points tighter than sub-investment-grade tenants for comparable property. Examples: Amazon (AA), Walmart (AA), Target (A), Costco (A+), Home Depot (A), FedEx (BBB), UPS (A-).
- Sub-investment-grade tenant: trades at wider cap rates reflecting the elevated credit risk; specific tenant credit quality drives the magnitude of the spread.
- No-rated or private tenant: requires individual credit analysis; cap rate impact depends on the specific tenant's financial profile, lease structure protections, and replacement-tenant prospects.
That premium only holds if the credit is real, which is why the rating on the cover is the start of the analysis rather than the end of it.
Sale-Leaseback Activity
One structure deserves its own treatment because of how directly it ties the lease back to corporate credit: the sale-leaseback. A corporate user (an operator, manufacturer, or retailer) sells the facility it owns and occupies to an institutional real estate buyer, then signs a long-duration NNN lease on the same building. The seller converts owned real estate into cash for general corporate purposes, debt reduction, working capital, acquisitions, or returns to shareholders, while keeping operational use of the space it just sold.
Sale-leaseback activity accelerated through the high-rate years of the early-to-mid 2020s, as expensive debt and tighter credit pushed many companies to tap their real estate for liquidity rather than borrow. The pricing has its own logic: corporate sellers typically accept 6.5 to 7.5 percent cap rates on their sale-leasebacks, wider than what an institutional buyer would pay for an arm's-length-leased building, which reflects the seller's own cost of capital and willingness to capitalize the rent obligation they are creating. The institutional buyer acquires at that wider cap rate, takes a long fresh NNN lease from a known corporate credit, and earns the spread to its longer-duration financing. The mechanic is one of the larger structural sources of industrial transaction volume in any given year, and a real capital-raising option corporate users weigh against traditional debt.
- Industrial Sale-Leaseback Transaction
A transaction in which a corporate owner-occupier sells its industrial facility to an institutional real estate buyer and simultaneously signs a long-duration NNN lease for the same building, keeping operational use while converting owned real estate into cash. The structure is most active when interest rates and corporate borrowing costs are high and companies prioritize balance-sheet liquidity over real estate ownership. Corporate sellers typically accept cap rates of roughly 6.5 to 7.5 percent, above tight institutional levels, and the buyer captures the spread between that cap rate and its longer-duration financing.
A seasoned industrial investor applies the resulting hierarchy without thinking about it. The building is the commodity. The lease and the credit behind it are the asset. Underwrite from the contract and the covenant inward, and the bricks become the last thing you check rather than the first.
