What Is a Triple Net (NNN) Lease?
A triple net lease — universally abbreviated NNN — is the most passive lease structure available in commercial real estate. In a NNN lease, the tenant pays not only base rent but also the three primary property expense categories — property taxes, building insurance, and maintenance/repairs. The "three nets" are the tenant's responsibility.
The result for the landlord: a relatively clean, predictable rent check with minimal expense exposure and management burden. No surprise tax bills. No arguing about who fixes the roof. The tenant handles it.
This is why NNN properties are the dominant investment vehicle for:
- Passive investors who want real estate exposure without active management
- 1031 exchange buyers who need to close within a 180-day window with minimum friction
- Out-of-state investors who can't manage a property locally
- Institutional buyers seeking predictable, credit-backed income streams
- High-net-worth individuals building a portfolio alongside other business interests
Lease Structure Comparison
Not all commercial leases are the same. Understanding where NNN sits on the spectrum of landlord vs. tenant responsibility is essential to underwriting any commercial deal correctly:
| Lease Type |
Landlord Pays |
Tenant Pays |
Landlord Risk |
| Gross / Full-Service |
All operating expenses |
Rent only |
High — all expense variability falls on landlord |
| Modified Gross |
Some expenses (base year) |
Rent + expense increases above base year |
Medium — partially hedged against expense growth |
| Net (N) |
Most expenses |
Rent + 1 net (usually taxes) |
Medium-high |
| Double Net (NN) |
Structural / roof / major systems |
Rent + taxes + insurance |
Medium-low — landlord still holds capital risk |
| Triple Net (NNN) |
Little to nothing (structural debated) |
Rent + taxes + insurance + maintenance |
Low — minimal ongoing obligation |
| Absolute NNN |
Nothing — including condemnation/casualty |
Everything, including roof and structure |
Very low — closest to a passive bond |
⚠ Read the actual lease. In the market, "NNN" is used loosely. Some listings describe a lease as "NNN" when the landlord retains structural and roof responsibilities — that's technically NN, not NNN. Always read the lease document, not the marketing description, to understand exactly who pays what.
Why 1031 Exchange Buyers Love NNN
NNN properties have become the dominant replacement vehicle for 1031 exchange investors, and for good reasons. When you're operating under a 45-day identification deadline and a 180-day closing window, predictability and speed are everything.

For 1031 buyers specifically, NNN delivers:
- Fast due diligence — no complex lease-up risk, no tenant negotiations, straightforward financials to verify. Can often close in 30–45 days with a motivated seller.
- Zero management presence required — an exchanger in Connecticut buying a NNN deal in Pennsylvania or New Jersey doesn't need to visit the property after closing. Tenant handles everything.
- Predictable cash flow during the exchange period — no surprise expense bills, no emergency maintenance calls at midnight. Income is what the lease says it is.
- Clear underwriting — NOI for a NNN property is essentially rent minus any minimal landlord obligations. Easy to model, easy to verify.

Credit Tenant Hierarchy
In NNN investing, tenant credit quality is everything. A NNN lease is only as good as the tenant's ability and willingness to pay rent and honor their obligations over a 10–20 year term. Here's how tenants are tiered:
Tier 1 — Investment Grade
National credit tenants with S&P investment-grade ratings (BBB- or higher)
Dollar General · Walgreens · CVS · McDonald's · Burger King · AutoZone · O'Reilly · Advance Auto · 7-Eleven · Starbucks (corporate) · National banks
Cap rate range: 5.5–7.0% (CT) · 5.0–6.5% (NJ) · Tightest competition, most liquid, lowest risk
Tier 2 — Regional Credit
Strong regional chains with multiple locations and operating history
Regional grocery chains · regional pharmacy/healthcare · strong regional restaurant chains · fitness chains with proven multi-unit track records
Cap rate range: 7.0–8.5% (CT) · 6.5–8.0% (NJ) · Best risk/reward zone for active investors
Tier 3 — Local / Single Location
Independent operators with one or few locations; personal guarantee only
Local restaurants · single-location retail · independent service businesses
Cap rate range: 8.0–10%+ · Higher yield compensates for higher credit risk; careful due diligence on operator financials required
⚠ Red flag tenants NDI scores down: Payday lenders, vape shops, check-cashing operations, and month-to-month tenants. These businesses have high failure rates, attract regulatory risk, and represent weak covenant strength regardless of what the lease says. A 10% cap rate on a payday lender NNN is not the same as a 10% cap rate on a regional grocery — the risk profiles are fundamentally different.
NNN Cap Rates in the Northeast
Cap rates for NNN properties vary not just by tenant credit quality, but also by geography, remaining lease term, and property condition. Here are current Northeast benchmarks:
| Tenant Type |
CT Range |
NJ Range |
Notes |
| Investment-grade national (Dollar General, Walgreens, CVS) |
5.5–7.0% |
5.0–6.5% |
Tightest cap rates; most competition; most liquid |
| Regional credit tenants |
7.0–8.5% |
6.5–8.0% |
Best risk/reward zone; NDI's target range |
| Local single-tenant NNN |

| Quick-service restaurant (QSR) absolute NNN |
5.5–7.0% |
5.0–6.5% |
Corporate vs. franchisee matters significantly; check obligor |
Key insight: The sweet spot NDI targets is the regional credit tenant segment at 7.0–8.5% in Connecticut — strong enough credit to close cleanly within a 1031 window, high enough yield to make financial sense. Investment-grade nationals trade at prices that leave little margin for error.
What Makes a Strong NNN Deal
Beyond the lease structure itself, here's NDI's checklist for a strong NNN acquisition:
- Long WALT (Weighted Average Lease Term) — 7+ years remaining is the target. At 3 years remaining, you have a rollover risk problem dressed up as a NNN property. Check renewal options — are they at market rent or below-market rent? Below-market rent at renewal is actually a negative (tenant won't renew; or you're locked into low rent).
- Investment-grade or strong regional credit tenant — Know who is actually obligated on the lease. A franchise location of a national brand has the franchisee as the obligor, not the corporate parent — very different risk profiles.
- Below-market rent with mark-to-market upside — If current rent is below prevailing market rates, the next renewal or new lease has embedded upside. This is value-add within a NNN structure — rare but valuable.
- Assumable financing at a below-market rate — If the seller has a 3.5% loan from 2021 that's assumable at 75% LTV, you're buying the debt along with the real estate. In today's rate environment, that's a significant additional value.
- Price in the $500K–$10M range — Maximum liquidity for 1031 exchange buyers. Deals in this range have the deepest buyer pool and easiest execution.
- Clean title, no environmental issues — Phase I environmental should show no recognized environmental conditions (RECs). Title should be clean with no mechanics' liens, easement conflicts, or litigation history.
- Rent escalations in the lease — Annual bumps of 1–2% per year (or periodic increases) protect against inflation. Flat rent over a 15-year term means your real yield declines every year inflation exists.
How NDI Scores NNN Deals
NNN lease structure is a positive signal across multiple dimensions of the NDI deal scoring rubric:
- 1031 Suitability (10% weight) — NNN deals score highest on 1031 suitability: passive income, fast closing potential, minimal management obligation. This dimension is directly boosted by NNN structure.
- Cap rate vs. submarket average (30% weight) — The most heavily weighted factor. NNN deals at above-average cap rates for their tenant/market combination score well here.
- Property condition & value-add potential (15% weight) — Below-market rent (mark-to-market upside), short WALT creating a repositioning opportunity, or assumable below-market debt all add to this score.
The trifecta NDI looks for: long WALT + credit tenant + NNN structure + above-market cap rate. When all four align, the deal earns a 7–9/10 score and gets flagged prominently in the daily alert.

Common NNN Investing Mistakes
1. Buying Short WALT and Calling It NNN
A NNN lease with 18 months remaining is not a NNN investment — it's a vacant building risk disguised with a few months of income. When the tenant leaves, you have a vacant building to re-lease or re-purpose. That's a value-add play, not a passive income play. Target 7+ years remaining WALT on any deal marketed as NNN.
2. Trusting the Label Over the Lease
The phrase "NNN" in a listing description is marketing language. It may describe a double net lease, a modified gross lease, or a NNN lease with significant landlord carve-outs for structural items. The only way to know what you're actually buying is to read the lease. Specifically: who is responsible for the roof? HVAC? Parking lot resurfacing? Structural repairs? Get it in writing.
3. Ignoring the Franchisee vs. Corporate Distinction
A McDonald's franchise location with 10 years remaining has a franchisee as the legal obligor on the lease — not McDonald's corporate. Franchisee credit quality varies dramatically. Some franchisees are sophisticated multi-unit operators with strong balance sheets; others are thinly capitalized single-unit operators. Always know who signs the lease.
4. Paying Investment-Grade Pricing for Weak Credit
A 6.0% cap rate is appropriate for a Walgreens with 12 years remaining. It is not appropriate for a local vape shop with a personal guarantee. Cap rates should be commensurate with credit risk — don't accept compressed cap rate pricing just because the listing says "NNN."
5. Ignoring Co-Tenancy Clauses in Strip Centers
Some NNN leases in multi-tenant centers include co-tenancy clauses: if an anchor tenant leaves, your tenant has the right to reduce rent or terminate. This is particularly common in power centers with major anchor tenants. A co-tenancy clause that isn't discovered until closing can completely change the risk profile of what looked like a stable NNN deal.
6. Not Modeling Flat Rent Against Inflation
A 10-year NNN lease with flat rent that was signed in 2016 has already lost ~30% of its real purchasing power to inflation. If a 2026 deal has flat rent for the next 10 years, you're buying a declining real yield stream. Always check rent escalation provisions — annual bumps of 1.5–2% per year are the minimum you should accept on a long-term NNN lease.

Frequently Asked Questions
What is a triple net (NNN) lease?
In a triple net lease, the tenant pays base rent plus three nets: property taxes, building insurance, and maintenance/repairs. The landlord collects net rent with minimal expense exposure and management burden. NNN is the preferred lease structure for passive investors and 1031 exchange buyers because it delivers predictable, hands-off income with minimal ongoing obligations.
What does NNN mean in real estate?
NNN stands for triple net — the three expense categories (nets) the tenant is responsible for: (1) property taxes, (2) building insurance, and (3) maintenance and repairs. The three N's represent each of the three nets passed through to the tenant. The landlord receives a "net net net" rent check with essentially no deductions for these operating costs.
What's the difference between NN and NNN?
In a double net (NN) lease, the tenant pays rent plus taxes and insurance, but the landlord remains responsible for structural repairs, roof, and major systems. In NNN, the tenant handles all three nets including maintenance. In an absolute NNN, the tenant takes on even structural obligations. Each level further reduces the landlord's responsibility and risk exposure.
What cap rates do NNN properties trade at in the Northeast?
NNN cap rates vary by tenant credit quality. In Connecticut: investment-grade nationals 5.5–7.0%, regional credit tenants 7.0–8.5%, local NNN 8.0–10%+. New Jersey runs about 50 basis points tighter. Medical/dental NNN trades at 6.5–8.0%. QSR absolute NNN at 5.5–7.0% depending on whether the obligor is corporate or franchisee.
Why are NNN properties popular for 1031 exchanges?
NNN properties are preferred for 1031 exchanges: (1) passive income structure — tenant pays all operating costs; (2) long WALTs mean predictable cash flow; (3) credit tenants reduce default risk; (4) clean, fast due diligence fits the 180-day closing window; (5) out-of-state buyers can own without local management. They're the path of least resistance for exchangers on a deadline.
What is WALT and why does it matter?
WALT (Weighted Average Lease Term) is the average remaining lease duration, weighted by each tenant's proportional rent. High WALT means predictable income; low WALT creates rollover risk. For NNN investments, target 7+ years remaining WALT. A "NNN" deal with 18 months remaining isn't a passive investment — it's a vacant building risk with a few months of income attached.
What credit tenants are considered investment-grade for NNN?
Investment-grade NNN tenants include Dollar General, Dollar Tree/Family Dollar, Walgreens, CVS, McDonald's, Burger King, Wendy's, AutoZone, O'Reilly, Advance Auto, 7-Eleven, Starbucks corporate, and major national banks. These carry S&P investment-grade ratings (BBB- or higher) and trade at the tightest cap rates. Note: franchise locations have the franchisee as the lease obligor, not the corporate parent.
What is an absolute NNN lease?
An absolute NNN (or "bondable NNN") lease is the most landlord-favorable structure: the tenant is responsible for everything including structural repairs, roof replacement, and even condemnation/casualty events. The landlord does literally nothing. Absolute NNN is most common with strong credit tenants on long-term leases (15–25 years). Fast food chains and convenience stores frequently use absolute NNN structures.
How do I find NNN properties in the Northeast?
NNN properties are listed on LoopNet, CoStar, and Crexi, and through net-lease specialist brokers. NDI tracks and scores NNN deals across CT, MA, NJ, NY, and PA daily — with cap rate vs. submarket analysis, WALT assessment, tenant credit quality ratings, and 1031 suitability scores. Free subscribers receive daily deal alerts with NNN deals flagged and scored.
What should I look for in NNN due diligence?
Key NNN due diligence: (1) Read the actual lease — verify who pays what; (2) Check WALT and renewal options/pricing; (3) Verify the legal obligor (corporate vs. franchisee); (4) Review rent escalation clauses; (5) Phase I environmental; (6) Structural inspection for deferred capital items; (7) Review any co-tenancy clauses in multi-tenant centers; (8) Confirm title is clean with no liens or easement issues.
What are common NNN investing mistakes?
Top mistakes: (1) Buying short WALT and treating it as passive — it's not; (2) Trusting the "NNN" label without reading the lease; (3) Not distinguishing franchisee from corporate obligor; (4) Paying investment-grade pricing for weak credit; (5) Missing co-tenancy clauses in strip centers; (6) Ignoring rent escalation — flat rent means declining real yield over time.
How does NDI score and flag NNN deals?
NNN structure is a green flag in NDI scoring, boosting 1031 suitability (10% weight) and the overall assessment. For NNN deals, NDI evaluates tenant credit quality, WALT remaining, rent escalation schedule, cap rate vs. submarket average, and 1031 suitability. The combination of long WALT + credit tenant + NNN + above-market cap rate is the trifecta that earns the highest deal scores.
