Triple Net Lease (NNN)

What Is a Triple Net Lease?

A triple net lease (NNN) is a commercial lease agreement where the tenant assumes responsibility for all three major categories of property operating expenses: property taxes (the first "N"), building insurance (the second "N"), and common area maintenance including structural repairs (the third "N"). The landlord receives base rent with virtually no operating expenses to manage or pay. This structure makes NNN properties among the most passive forms of real estate investment — some owners joke that their only responsibility is depositing the rent check and filing their taxes.

Why NNN Leases Appeal to Passive Investors

For investors seeking truly hands-off income, NNN leases are the gold standard. The tenant handles everything from property taxes to roof repairs to snow removal. There are no midnight maintenance calls, no property management fees to pay, and no expense variability eating into your returns. Your income is predictable and fixed (or escalating on a known schedule) for the duration of the lease, which typically runs 10–25 years. This predictability makes NNN properties particularly popular with retirees, 1031 exchange buyers looking to simplify, and high-net-worth individuals who want real estate returns without real estate headaches.

Credit Tenant NNN Investments

The most sought-after NNN investments are leased to "credit tenants" — publicly traded companies or large franchisees with strong financial backing. Think McDonald's, Walgreens, Dollar General, Starbucks, or CVS. The value of a credit tenant NNN property is driven primarily by the strength of the tenant's credit and the remaining lease term. A Walgreens with 20 years remaining on a corporate-guaranteed NNN lease trades at a premium (lower cap rate, higher price) because the income stream is considered nearly as safe as a bond. Typical cap rates for credit tenant NNN properties range from 5% to 7%, depending on the tenant, location, and remaining lease term.

Cap Rates and Pricing

NNN property pricing is driven by three factors: tenant credit quality, remaining lease term, and location. A brand-new Chick-fil-A with a 20-year corporate-guaranteed lease in a growing suburb might trade at a 4.5% cap rate. A regional restaurant chain with 5 years remaining in a secondary market might trade at an 8% cap rate. Every year of remaining lease term that burns off slightly increases the cap rate (decreasing value) because the certainty of future income diminishes. Investors must balance the desire for strong credit tenants against the lower yields those tenants command. Higher cap rates mean more income but more risk.

Lease Term and Re-Leasing Risk

The biggest risk in NNN investing is what happens when the lease expires. If McDonald's vacates your property after 20 years, you are left with a building specifically designed for a fast-food restaurant in a location that McDonald's has decided is no longer profitable. Re-leasing can be challenging and expensive — you may need to renovate the space, accept a lower-credit tenant, or offer significant concessions. Smart NNN investors pay close attention to lease renewal options, remaining term, and the adaptability of the building for alternative tenants. Properties with 5 years or less remaining on the lease carry significantly more risk and should be priced accordingly.

NNN Lease Considerations

Before investing in a NNN property, read the actual lease document carefully. Verify exactly which expenses are the tenant's responsibility — some leases labeled as "NNN" are actually modified net leases where the landlord retains responsibility for roof and structural repairs. Check for rental escalations — a flat-rate NNN lease with no increases loses purchasing power to inflation over a 20-year term. Understand the tenant's right to sublease or assign the lease. Evaluate the location's long-term viability — demographics can shift dramatically over a 20-year lease term. And always get a Phase I environmental assessment, especially for gas stations, dry cleaners, or auto service tenants who may leave contamination liabilities behind.
