A triple net lease, often shortened to NNN, is a commercial lease structure where the tenant — not the landlord — pays property taxes, building insurance, and maintenance costs, on top of base rent. For landlords, it is one of the closest things commercial real estate offers to a truly passive income stream. For tenants, it trades a lower headline rent for direct exposure to costs that can rise unpredictably.
What changed in 2026
- NNN cap rates have moved with the broader interest rate environment, since these deals are often financed and compared against bond-like fixed income alternatives. Check current rates in your target market before assuming a number.
- Tenant credit quality is under more scrutiny than in the low-rate years, since a triple net lease is only as reliable as the tenant's ability to keep paying and maintaining the property.
- More investors are accessing NNN deals through funds and syndications, not just direct single-tenant purchases, lowering the entry capital required.
The three nets, explained
- Property taxes — the tenant reimburses or pays directly.
- Building insurance — the tenant covers premiums for the property.
- Maintenance — the tenant handles most repairs and upkeep, sometimes excluding structural or roof issues depending on the lease.
Compare that to a gross lease, where the landlord pays all operating costs out of the rent collected, and the difference in landlord workload is significant.

Why landlords like it
The appeal is predictability: rent income arrives without the landlord absorbing surprise cost spikes from a new tax assessment, an insurance rate hike, or an unexpected repair. That predictability is why triple net deals often trade at lower cap rates than comparable properties with a gross lease — investors are willing to accept a lower yield in exchange for less operational risk and effort.
Why it is not fully hands-off
"Triple net" describes cost responsibility, not zero landlord involvement. Landlords still typically handle:
- Structural repairs to the roof or foundation, depending on how the lease defines maintenance responsibilities.
- Lease enforcement, including ensuring the tenant is actually maintaining insurance coverage and paying taxes on time.
- Re-tenanting risk if a single-tenant NNN property loses its tenant, since the entire income stream can disappear at once, unlike a multifamily property with many tenants.
Who NNN leases suit
Tenants tend to be national or regional retail, restaurant, or service chains with strong enough credit to commit to long lease terms — often ten to twenty-five years. For investors, this makes triple net properties resemble a bond with real estate upside: predictable income backed by a tenant's creditworthiness, plus the property itself as collateral. This differs meaningfully from the volatility of shorter residential leases discussed in commercial vs residential real estate.
This is general information, not financial, legal, or tax advice. Lease terms vary significantly by property and tenant — review the actual lease document and consult a professional before investing.
FAQ
Is a triple net lease better for landlords or tenants?
Neither universally — landlords get predictability and lower effort; tenants get more control over the space and sometimes lower base rent.
Can a triple net lease still fail?
Yes, if the tenant defaults, goes bankrupt, or vacates. The landlord is then exposed to the property's full costs and the challenge of re-tenanting.
Are triple net properties good for beginners?
They can be, given their relative simplicity, but tenant credit analysis and lease review still require real diligence before buying.
How long do triple net leases typically run?
Often ten to twenty-five years for national tenants, though terms vary by property type and negotiating leverage.
