What is a Triple Net Lease (NNN)?

An Essential Property Management Term

Triple net leases, also known as NNN leases, represent a leasing arrangement where the tenant assumes the majority of the operating expenses of the property, including real estate taxes, building insurance, and maintenance, in addition to their rent and utility costs. These leases are prevalent in the commercial real estate sector and offer distinct advantages and challenges to both landlords and tenants.

Triple Net Lease Example

In practice, triple net lease investments often consist of a portfolio of high-grade commercial properties, such as office buildings, malls, industrial parks, or free-standing buildings like pharmacies or banks. These properties are typically fully leased by a single tenant, ensuring a stable, in-place cash flow. The lease terms usually span 10 to 15 years, featuring contractual rent escalations to account for inflation and market changes.

NNN Pros & Cons



  • Predictable Income: With the tenant covering most expenses, landlords can enjoy a more predictable income stream.
  • Lower Operating Costs: Since tenants handle property-related expenses, landlords have lower operating costs.


  • Less Control Over Property Maintenance: Landlords may have less control over how the property is maintained, potentially affecting long-term value.



  • Operational Control: Tenants have greater control over the property’s operational aspects, allowing them to manage costs more effectively.
  • Customization: Tenants can customize the space to fit their business needs without extensive landlord oversight.


  • Higher Operating Costs: Tenants bear the responsibility for most property expenses, which can be higher than in other lease types.

The Triple Net Lease in Practice

Typically, triple net lease investments consist of portfolios with high-grade commercial properties, such as office buildings and malls, providing investors with stable income. These leases often require tenants to be financially stable, offering security to both parties involved.

Other Net Leases

  • Single net (N): This lease type transfers minimal risk to the tenant, who pays property taxes alongside rent and utilities.
  • Double net (NN): More common than single net, the tenant pays property taxes and insurance premiums, but maintenance costs fall to the landlord.

Triple net leases offer a unique set of advantages and considerations for both landlords and tenants, making them a significant component of the commercial real estate market.

Triple Net Leases vs. Single Net Leases and Double Net Leases

When navigating the commercial real estate market, understanding the distinctions between the various types of net leases—triple net (NNN), single net (N), and double net (NN)—is crucial for both landlords and tenants. Each lease type delineates a different allocation of property expenses between the landlord and tenant, impacting operational control, financial responsibilities, and investment returns.

Triple Net Leases (NNN)

Triple net leases place the majority of property expense responsibilities on the tenant. In addition to rent and utilities, the tenant is responsible for real estate taxes, building insurance, and maintenance costs. This type of lease offers landlords a predictable income stream with minimal operational costs and gives tenants more control over the property, including maintenance and operational aspects. However, it also imposes higher financial obligations on the tenant.

Advantages for Landlords:

  • Predictable income with fewer operational hassles.
  • Reduced responsibility for property expenses.

Advantages for Tenants:

  • Greater control over property operations and maintenance.
  • Potential for customization and control over operating costs.

Single Net Leases (N)

In a single net lease, the tenant is responsible for paying the property taxes in addition to the base rent and utilities. The landlord retains responsibility for building insurance and maintenance costs. This lease type shifts a minimal amount of financial and operational responsibility to the tenant compared to triple net leases.

Differences from Triple Net Leases:

  • Lower financial obligation for the tenant concerning property expenses.
  • Landlord maintains greater responsibility for insurance and maintenance costs.


Double Net Leases (NN)

Double net leases require the tenant to pay for property taxes and insurance premiums, along with the rent and utilities. Maintenance responsibilities, especially for significant structural or operational systems, typically remain with the landlord. This lease type offers a middle ground between single and triple net leases, distributing financial and operational responsibilities more evenly between the landlord and tenant.

Differences from Triple Net Leases:

  • The tenant has a reduced financial burden since maintenance costs are generally not their responsibility.
  • Offers a balance of control and responsibility between the landlord and tenant.

Comparison Overview

Choosing between a triple net, double net, or single net lease involves weighing the balance of financial and operational responsibilities each party is willing to assume. Triple net leases offer landlords a hands-off investment with stable returns, while tenants gain operational control at the cost of higher expenses. Single and double net leases offer varying degrees of responsibility sharing, making them suitable for different investment strategies and operational preferences in the commercial real estate market.
