Triple Net Lease Explained

A triple net lease (NNN) is a commercial lease where the tenant pays, in addition to rent, three major expense categories: property taxes, building insurance, and maintenance and repairs. This structure shifts operating costs away from the landlord to the tenant, making it a popular choice for investors seeking mostly passive income with minimal hands-on management.

The Three Nets: What the Tenant Pays

A triple net lease divides property expenses into three buckets beyond base rent:

Property taxes. The tenant pays the annual real estate tax bill to the local assessor. If taxes rise in a given year—which they often do—the tenant absorbs the increase. This protects the landlord from unexpected tax surprises but can be a shock to tenants unfamiliar with the structure. Property tax is usually the largest of the three net expenses.

Insurance. The tenant maintains general liability insurance and property insurance on the building. This includes coverage against fire, theft, and weather damage. The tenant may also carry workers’ compensation if they have employees. The landlord is typically listed as an additional insured, protecting their interest, but the tenant selects the policy and pays the premium.

Maintenance and repairs. The tenant is responsible for all routine maintenance—HVAC service, parking lot repaving, roof repairs, plumbing and electrical fixes—and structural repairs. The landlord generally does not step in except in catastrophic scenarios. This clause is intentionally broad, and disputes sometimes arise over what counts as “maintenance” (tenant responsibility) versus “capital improvement” (sometimes landlord responsibility). A well-drafted lease spells this out: the tenant pays for repairs under a certain dollar threshold, and the landlord covers structural elements like the foundation or main roof replacement.

The motivation is clear: the landlord’s job shrinks to collecting rent and ensuring the tenant doesn’t trash the property. The tenant handles day-to-day operations and long-term upkeep. This appeals to landlords who want predictable cash flow without managing contractors or dealing with surprise repair bills.

Why Investors Choose This Structure

Passive income appeal. Once the lease is signed and the rent is deposited, a landlord’s involvement is minimal. There are no calls about a leaky faucet or a complaint about the parking lot. The tenant bears that burden. For investors seeking to own property without active management, a triple net lease is the closest thing to a hands-off investment in real estate.

Predictable cash flow. Base rent is fixed (unless there are escalation clauses for inflation). The landlord knows exactly what comes in each month. Operating surprises are rare, since the tenant covers the costs.

Longer lease terms. NNN leases often run 10, 15, or 20+ years. A long, stable lease from a creditworthy tenant (think a national restaurant chain or pharmacy) feels low-risk and is easy to finance. Lenders favor these deals because the cash flow is visible years in advance.

Lower acquisition price. Because tenants are taking on more risk and cost responsibility, investors often pay less for a NNN property than for a traditional lease where the landlord handles expenses. This lower entry price can improve returns for the buyer.

Common Tenants and Property Types

Triple net leases are standard in commercial real estate. You’ll often see them in:

• Retail: A Walgreens or CVS paying rent plus all three nets.
• Restaurants: A chain restaurant (Chipotle, Subway, etc.) leasing a storefront.
• Office: Professional services (medical, dental, law) leasing space.
• Industrial: Warehouses or light manufacturing.

The tenant is usually a business with steady revenue and a track record. A small family-run business might lease on a traditional basis (landlord covers utilities and maintenance); a national brand can handle NNN terms easily.

Investor Returns and Risk

The landlord’s return comes from rent. Because the tenant covers taxes, insurance, and maintenance, the rent figure usually looks lower than it would on a standard lease where the landlord is responsible for those costs. A comparable standard lease might be $60,000 per year with the landlord covering the three nets; a NNN lease on the same property might be $50,000 per year plus the tenant paying the nets.

From a tax perspective, NNN leases have a wrinkle: the rent the tenant pays for taxes, insurance, and maintenance is often called a “rent equivalent” by the IRS, and the landlord may be able to pass through certain deductions. A tax professional should review the structure.

Risk: The main risk is tenant default. If the business fails, the tenant stops paying rent and abandons the property. The landlord then must find a new tenant, possibly in a market where the property has aged and suffered from deferred maintenance. A well-drafted NNN lease includes provisions for the landlord to inspect, ensure the tenant maintains insurance, and step in if the tenant breaches. The landlord can also set aside a reserve—collecting extra rent—to cover gaps.

Single, Double, and Net Leases

NNN is one point on a spectrum:

• Gross lease: Landlord pays all taxes, insurance, maintenance, utilities. Rent is higher. Landlord bears all operating risk.
• Net lease (single net): Tenant pays property tax; landlord pays insurance and maintenance.
• Double net (NN): Tenant pays property tax and insurance; landlord pays maintenance.
• Triple net (NNN): Tenant pays all three: property tax, insurance, and maintenance.

More nets mean lower rent but more tenant responsibility.
