What Is a Triple Net Lease? A Hawaii Commercial Real Estate Guide

By Benavente Group

Walk into almost any conversation about commercial real estate investing, and one phrase comes up constantly. NNN. Or triple net. Or sometimes just "the tenant pays everything."

The phrase shows up in listings, financing conversations, and broker pitches, but it's also one of the most commonly misunderstood concepts in commercial leasing. And in Hawaii specifically, the way NNN structures interact with leasehold land and local cost pressures makes understanding them even more important.

So let's get the clear answer: what is a triple net lease, how does it differ from other lease types, and what does it mean for owners and investors evaluating Hawaii commercial property?

The Plain English Definition

A triple net lease (often abbreviated NNN) is a commercial lease structure where the tenant pays base rent plus the three "nets": property taxes, property insurance, and operating expenses, including maintenance.

That's the whole concept. The landlord receives a relatively clean rent stream, and the tenant takes on most of the property's operating costs.

In a typical NNN scenario, the tenant is responsible for property tax bills, property insurance premiums, common area maintenance, repairs, landscaping, utilities, and management costs. The landlord may still be responsible for structural elements like the roof and foundation, depending on how the lease is written, but most other costs flow through to the tenant.

When asking what is a triple net lease, the simplest way to think about it is: minimum landlord involvement, maximum tenant responsibility, predictable returns.

How NNN Differs from Other Lease Structures

Commercial leases exist on a spectrum from gross (landlord pays everything) to absolute net (tenant pays everything). NNN sits near the tenant-pays end, with a few common variations.

A gross lease has the tenant paying a single monthly rent and the landlord paying all operating costs. Common in office buildings.

A modified gross lease falls in the middle, where some expenses are split between landlord and tenant. Common in multi-tenant office and mixed-use properties.

A single net (N) lease has the tenant paying property taxes plus rent.

A double net (NN) lease has the tenant paying property taxes and insurance plus rent.

A triple net (NNN) lease has the tenant paying taxes, insurance, and maintenance plus rent.

An absolute net lease (sometimes called bondable) goes further, putting even structural and capital repairs on the tenant.

The differences sound subtle but they matter enormously for valuation and risk allocation.

Why Investors Prefer NNN

For income-focused investors, the NNN structure has several compelling advantages.

Predictable income. Because the tenant absorbs expense increases, the landlord's net income is largely insulated from rising insurance premiums, tax assessments, or maintenance costs.

Lower management burden. Single-tenant NNN properties often require minimal day-to-day involvement. Some owners refer to it as a near-passive investment.

Long lease terms. NNN tenants typically sign 10 to 20+ year leases with built-in rent escalations, which provides extended income visibility.

Cleaner NOI. Because the property's expenses are largely passed through, the net operating income tends to be stable and easier to underwrite.

This is why understanding what is a triple net lease matters so much for valuation. Properties under solid NNN structures tend to trade at lower cap rates (higher prices) than comparable properties under gross leases, even when the underlying real estate is identical.

Why Tenants Accept NNN

If the tenant pays everything, why agree to it? Several reasons.

Lower base rent. NNN base rents are typically lower than gross-equivalent rents, which gives tenants more control over their occupancy costs.

Control over operations. Tenants directly responsible for maintenance can choose their own vendors, set their own service levels, and avoid being charged inflated landlord-managed costs.

Customization flexibility. Long-term NNN tenants often have more latitude to modify the space, install signage, and make build-outs.

Predictability. A tenant absorbing operating costs can plan around them, while a tenant under a gross lease with annual escalators may face unpredictable rent jumps.

For credit tenants signing long-term leases, NNN often makes sense for both sides.

The Risks NNN Doesn't Eliminate

Investors sometimes describe NNN properties as "mailbox money." That's overstated.

Vacancy risk. If the tenant leaves, defaults, or fails, the landlord suddenly owns all those operating costs with no income to offset them. Single-tenant NNN properties are concentrated risks.

Tenant credit risk. The lease is only as strong as the tenant. A long-term NNN with a weak credit tenant is meaningfully less valuable than the same lease with an investment-grade tenant.

Reversion risk. When the lease ends, the property may need significant capital to re-tenant, especially if the original tenant heavily customized the space.

Hidden cost pass-throughs. Some NNN leases have caps or carve-outs that limit what can be passed through, leaving the landlord exposed to certain cost categories.

NNN in Hawaii

Hawaii's commercial real estate market features NNN leases prominently, especially for single-tenant retail, fast food, banks, drugstores, and similar uses. But Hawaii adds wrinkles that mainland NNN investors often miss.

Leasehold land complications. When the underlying property is itself on a ground lease, the tenant's NNN obligations may include reimbursing the landowner-lessee for ground rent payments. This adds a layer of cost the tenant needs to understand and the landlord needs to disclose.

Insurance pressures. Hawaii's insurance market, particularly for hurricane and flood coverage, has tightened significantly. Tenants under NNN leases bear these increases directly, and rapid jumps can create disputes or push tenants toward renegotiation.

Property tax volatility. As assessments adjust, NNN tenants absorb tax increases. Owners and tenants both have an interest in active management of property tax appeals when assessments outpace market value.

Limited comparable transaction data. Hawaii's thin transaction market means NNN cap rate benchmarks may need supplementation with broader Pacific or mainland data, adjusted for local conditions.

For Hawaii commercial owners, fully understanding what is a triple net lease means understanding both the structure itself and how Hawaii-specific factors flow through it.

What This Means for Property Valuation

NNN lease structure directly drives commercial real estate appraisal outcomes. A property with strong long-term NNN leases to creditworthy tenants commands premium pricing because the income is stable, predictable, and largely insulated from expense volatility.

The valuation isn't just about the headline rent. It's about lease term remaining, tenant credit, rent escalation structure, expense pass-through completeness, and the reversion risk at lease end. A skilled appraiser examines all of these factors when applying the income capitalization approach to a NNN-leased property.

The Bottom Line

So, what is a triple net lease? It's the commercial lease structure where the tenant pays base rent plus property taxes, insurance, and operating expenses, leaving the landlord with a relatively clean income stream and lower management burden.

For Hawaii commercial property owners and investors, NNN structures offer real benefits but also carry real risks, especially when layered with leasehold land, rising insurance costs, and tenant credit considerations. The structure itself doesn't guarantee good returns. The tenant, the lease terms, and the underlying real estate all still matter.
