Triple Net Leases - Demystified
Triple Net Leases, Demystified.
How investors collect rent while someone else fixes the roof: the mechanics, the math, and the market as it actually stands in 2026.
There is a kind of real estate investment that promises monthly checks without trash pickup, repairs, or weekend phone calls about a leaky faucet. It's called a triple net lease, or NNN, and it's the closest thing in real estate to owning a bond: long-term contracts, creditworthy tenants, predictable income, and a roof you'll never personally have to climb on.
It is also where many otherwise sophisticated investors discover what "concentrated tenant risk" actually means. The mechanics are simple. The math is forgiving. The trap is in the credit analysis, the lease language, and a sense of false security that the phrase "corporate guarantee" tends to inspire.
What "Triple Net" Actually Means.
Commercial leases are categorized by how much of the operating expense burden the tenant assumes.
- Gross Lease
- Landlord pays taxes, insurance, and maintenance. Tenant pays one rent number.
- Single Net (N)
- Tenant pays property taxes. Landlord handles insurance and maintenance.
- Double Net (NN)
- Tenant pays property taxes and insurance. Landlord still handles maintenance.
- Triple Net (NNN)
- Tenant pays property taxes, insurance, and most maintenance. Landlord typically retains responsibility for the roof and structural elements. Standard issue for most retail single-tenant deals.
- Absolute NNN
- Tenant pays everything, including roof and structure. The landlord is, for practical purposes, just collecting rent.
- Bondable Lease
- Absolute NNN with no termination rights. The closest thing to a corporate bond that real estate offers, and priced accordingly.
How Returns Actually Work.
Two numbers tell most of the story.
Cap rate is net operating income divided by purchase price. A $1 million property generating $65,000 in NOI trades at a 6.5% cap rate. Lower cap rates reflect lower perceived risk: longer leases, stronger credit, prime locations. Higher cap rates compensate for risk: shorter terms, weaker credit, or secondary markets.
Spread is the gap between your cap rate and your borrowing rate. Buy at a 7% cap, borrow at 5.5%, and you have positive leverage. When borrowing costs exceed your cap rate, the math stops working.
The mental model is closer to bond investing than to traditional landlording. Tenant credit is your bond rating. Lease term is your maturity. Rent escalations are your inflation hedge. Cap rate compression and expansion are the equivalent of price moves on a bond when yields shift.
What Works. What Doesn't.
A balanced look at why investors keep coming back, and what tends to surprise them when they do.
- Truly passive income.Most NNN owners spend close to zero hours a month managing the property. The tenant runs the operation. You run the deposit slips.
- Long, predictable cash flow.Lease terms commonly run 10 to 25 years, often with built-in rent escalations every few years and corporate guarantees from the tenant's parent entity.
- Access to investment-grade tenants.Many NNN deals involve publicly traded companies with rated debt: McDonald's, FedEx, Dollar General, large drugstore chains, major QSR franchisees.
- Tax treatment is unusually friendly.1031 exchange eligibility, accelerated depreciation, and (under the OBBBA signed July 4, 2025) the permanent restoration of 100% bonus depreciation on qualifying components.
- Inflation hedges built in.Most leases include scheduled rent bumps, sometimes CPI-linked. Your income generally moves with prices over a long horizon.
- Bond-like income with real estate upside.Coupon-like cash flow, an appreciating underlying asset, and a stepped-up basis at death.
- Single-tenant means binary.The building is 0% leased or 100% leased. There is no middle ground when something goes wrong.
- Tenant credit risk is concentrated risk.When a corporate guarantor stumbles (Red Lobster's Chapter 11 in May 2024), your entire income stream stumbles with it.
- "Investment grade" today isn't always tomorrow.Walgreens was the gold-standard NNN tenant for decades. Then came 1,200 announced closures and a Sycamore take-private.
- Renewal leverage favors the tenant.At lease end, your tenant either renews on their terms or walks. Specialized buildings (former drugstores, former banks) can be notoriously hard to re-tenant.
- Interest-rate sensitive.NNN cap rates trade as a spread over Treasury yields. When rates rise, cap rates expand and your existing property's value falls, even if rent never changes.
- Illiquid.You can sell the building. You cannot sell it in a week. Pricing depends heavily on remaining lease term and prevailing rate conditions at the moment you list.
The Current State, Briefly.
As of Q1 2026, after two years of repricing.
Cap rates stabilized in late 2025 after roughly three years of steady increases. The Federal Reserve cut rates three times in late 2025, ending the year at a target range of 3.50% to 3.75%, and then held steady at both its January and March 2026 meetings. Bid-ask spreads have narrowed, transaction activity is recovering, and 100% bonus depreciation has been permanently restored.
Cap rates remain bifurcated by tenant credit and brand strength. Investment-grade and high-demand operators continue to trade at meaningful premiums to weaker credits and shorter remaining terms.
The broader cycle: cap rates bottomed near 5.60% at year-end 2022, peaked around 6.97% in mid-2025, and have since drifted back slightly. That 137-basis-point swing translated, on stable rent, to a meaningful decline in property values for owners who bought near the top.
Five Risks Investors Underestimate.
The math is forgiving. The execution is where deals quietly go wrong.
-
Single tenant means binary.
A multi-tenant building with one bad tenant is 80% occupied. A single-tenant NNN with one bad tenant is 0% occupied. The same loss looks dramatically different on a P&L, and the financing assumes you keep paying the mortgage either way.
-
Corporate guarantees age. Sometimes badly.
The credit profile that justified your cap rate at acquisition is not necessarily the profile you'll have in year ten. Walgreens, Red Lobster, and Bed Bath & Beyond were all once considered safe. Re-underwrite tenant credit annually, not just at purchase.
-
Re-tenanting cost is rarely modeled honestly.
At lease end you may face 6 to 12 months of vacancy, tenant improvement allowances of $20 to $100 per square foot, broker commissions, and possibly a rent reset. None of that lives in the going-in cap rate.
-
Cap rate moves are exit-value moves.
Your cash flow doesn't change when interest rates rise. Your sale price does. The 137-basis-point cap rate expansion between late 2022 and mid-2025 translated, on stable rent, to roughly a 20% decline in valuation for properties trading near the average.
-
The credit lookup is doing more work than you think.
S&P's BBB- and BBB are both "investment grade." One downgrade puts the tenant in junk territory, with a secondary market that wants to discount aggressively. Watch trajectory, not just current grade.
Is NNN Right for You?
Five questions to answer honestly before you write the check.
The Bottom Line.
Triple net leases are an elegant instrument: long contracts, creditworthy tenants, near-zero operational drag, and unusually friendly tax treatment. For investors with patience, capital, and real underwriting discipline, they can be a foundational portfolio holding.
For investors who confuse "corporate guarantee" with "safe" and treat the cap rate as the whole analysis, they can be expensive lessons.
The market in 2026 is more rational than it has been in years. Cap rates have stabilized, bid-ask spreads have narrowed, the Federal Reserve is currently on hold at 3.50% to 3.75% with at most one cut anticipated for 2026, and 100% bonus depreciation has been permanently restored as a tailwind for serious investors. That is a constructive backdrop, not a green light.
The right way to enter this market is with clear-eyed credit analysis, a long time horizon, and the humility to remember that a long lease is only as good as the company standing behind it. We're here when you're ready to think it through.
