Key Takeaways
- In a triple-net lease, the tenant covers taxes, insurance, and maintenance. But that only works if the tenant is creditworthy
- NNN returns are typically lower than value-add multifamily, but you barely have to touch the property. It's a yield play, not a growth play
- Tenant credit quality is the whole deal: a corporate guarantee from a national chain is a completely different risk profile than a local franchise operator
- These properties trade on cap rate and remaining lease term. The physical building is often secondary to the income stream
In commercial real estate, the lease structure defines the economics of the deal as much as the location or the purchase price. And no lease structure generates more questions from investors than the triple net — commonly abbreviated NNN. It is simultaneously one of the simplest concepts in real estate and one of the most misunderstood. People hear "triple net" and assume it means hands-off, passive, worry-free. The reality is more nuanced — and more interesting — than the shorthand suggests.
The Three Nets Explained
A triple net lease shifts three categories of operating expense from the landlord to the tenant. The "three nets" are:
Property taxes. The tenant pays the real estate taxes assessed on the property either directly to the taxing authority or as a reimbursement to the landlord. In a market where property taxes represent $2 to $3 per square foot of building area, this is a meaningful expense.
Insurance. The tenant carries and pays for the building insurance policy — or reimburses the landlord for the cost. In hurricane-prone markets like South Florida, where insurance can cost $1,500 to $2,800 per unit on multifamily and proportionally heavy on commercial space, this transfer is significant.
Maintenance and repairs. The tenant is responsible for maintaining the property — from the roof to the parking lot to the HVAC system. In a true NNN lease, the landlord's obligation is essentially limited to owning the building and collecting rent. Everything else is the tenant's problem.
The result is a "net" rent stream to the landlord — what they collect is what they keep, with no operating expenses to offset against it. This predictability is the fundamental appeal of NNN investing.
Who Uses Triple Net Leases
NNN leases are overwhelmingly concentrated in single-tenant commercial properties: freestanding retail buildings (Dollar General, Walgreens, Starbucks), quick-service restaurants (McDonald's, Chick-fil-A), auto service facilities (Jiffy Lube, O'Reilly Auto Parts), and certain industrial and medical office buildings. The common thread is a creditworthy tenant occupying the entire building under a long-term lease — typically 10 to 25 years with renewal options.
In multifamily, true NNN leases are uncommon. Apartment leases are typically gross leases where the landlord bears operating expenses and builds those costs into the rent. This is one of the key structural differences between multifamily and commercial net lease investing — and it affects everything from risk profile to management intensity.
A triple net lease doesn't eliminate risk. It concentrates it. Instead of managing a building's operating expenses, you're managing one thing: the creditworthiness and staying power of a single tenant. If they pay, you're fine. If they don't — or if they leave — you own an empty building with a very specific use case.
The Investment Case for NNN
The pitch for NNN investing is straightforward and genuinely compelling for the right investor. You buy a building with a creditworthy tenant on a long-term lease. The tenant pays all the operating costs. You collect net rent — typically with contractual escalations of 1 to 2 percent annually — and hold for a defined period. The management burden is minimal. The income is predictable. You're essentially buying a bond secured by real estate.
For investors who have spent years managing value-add deals — handling renovations, dealing with tenant issues, fighting insurance companies — the appeal of NNN is visceral. The promise of collecting checks without fielding midnight maintenance calls is genuinely attractive, especially as portfolio owners age or seek to diversify away from management-intensive assets.
The numbers reflect this demand. Investment-grade NNN properties with 15+ years of remaining lease term trade at cap rates of 4.5 to 6 percent — compressed pricing that reflects the perceived safety of the cash flow. A Walgreens with 20 years remaining on a corporate lease in a good location might trade at a 5.25 cap. The buyer is paying a premium for certainty.
The Risks Nobody Talks About
The NNN pitch papers over several risks that deserve serious consideration.
Tenant credit risk. Your entire income depends on one tenant. If that tenant files for bankruptcy — as Rite Aid, Bed Bath & Beyond, Tuesday Morning, and countless other retailers have done — your "passive" investment suddenly requires active problem-solving. You own a vacant, purpose-built retail building that may cost six figures to re-tenant.
Re-tenanting risk. When a NNN tenant vacates — whether through bankruptcy, lease expiration, or early termination — the building often requires significant modification for a new tenant. A former Walgreens doesn't easily convert to anything else. The layout, the drive-through configuration, the pharmacy infrastructure — it's all specific. Finding a replacement tenant can take 12 to 24 months and cost $200,000 to $500,000 in tenant improvements.
Residual value risk. At the end of a 20-year lease, you own a 20-year-old single-purpose building. The roof may need replacement. The parking lot needs resurfacing. The HVAC system is at end of life. All of these costs — which the tenant was responsible for during the lease — now fall to you if you need to re-lease or sell the property.
The safest-looking investments often carry the most concentrated risk. A portfolio of twenty apartment units with twenty separate tenants is inherently more diversified than a single building with one tenant — even if that tenant is a Fortune 500 company. Diversification isn't about asset size. It's about how many independent sources of income stand between you and a zero.
NNN vs. Multifamily: Different Tools for Different Goals
This is where the distinction matters most. Value-add multifamily operators create returns through construction, renovation, and active management. NNN investing is the opposite. It's passive by design. It rewards capital allocation, not operational execution.
That doesn't make it wrong — it makes it different. An investor who wants predictable cash flow without management obligations should seriously consider NNN. An investor who wants higher total returns and is willing to invest the time and operational effort should consider multifamily. Most institutional investors hold both — NNN for stability and multifamily for growth.
The key insight is that NNN returns are capped. Your upside is the lease escalation — 1 to 2 percent a year. In multifamily, a well-executed renovation can increase NOI by 30 to 50 percent in 18 months. The return profiles are fundamentally different, and the investor's choice should reflect their goals, risk tolerance, and operational capacity.
How to Evaluate a NNN Opportunity
NNN has a place in a portfolio, but investors should be clear-eyed about what it is and what it isn't. An operator's competitive advantage — buying buildings that need work, fixing them, and increasing their income — doesn't translate to NNN. That asset class rewards patient capital and credit analysis.
Anyone considering NNN exposure should evaluate it on the real risks: research the tenant's financial health independently, understand what happens at lease expiration, and know the re-tenanting cost assumptions. The prettiest investment in commercial real estate can also be the most fragile if the single tenant goes away.
