Triple Net Lease: The Landlord Who Mails Invoices, and What He's Really Bought
In a triple net (NNN) lease, the tenant pays rent plus the property's three big operating loads — taxes, insurance, and maintenance. The landlord's job collapses to collecting rent and monitoring the lease; the tenant runs the building it occupies. That's why NNN properties — the freestanding pharmacy, the fast-food pad, the dollar store, the distribution hub — are marketed as 'mailbox money' and priced closer to bonds than to buildings.

This guide is for investors and sponsors evaluating NNN deals — what the lease types actually mean, how the pricing works, and the underwriting truth the brochures soften: a triple net investment is a credit instrument wearing a building, and the credit is what you're buying.
The lease spectrum: N, NN, NNN, and absolute net
| Lease type | Tenant pays | Landlord retains |
|---|---|---|
| Gross / full-service | Rent only | All operating costs (office norm) |
| Single net (N) | Rent + property taxes | Insurance, maintenance |
| Double net (NN) | Rent + taxes + insurance | Structure: roof, walls, parking |
| Triple net (NNN) | Rent + taxes + insurance + maintenance | Often still the roof & structure — read the lease |
| Absolute net | Everything, including roof, structure, even casualty rebuild | Nothing but the deed |
The labels are marketing; the lease is the contract. Plenty of properties sold as 'NNN' leave the roof and structure with the landlord — a six-figure surprise on an older building. The only question that matters is what the document says about every expense category, including capital items, management, and what happens at casualty. On true absolute-net deals (common in sale-leasebacks), the landlord's obligations genuinely round to zero.
Why tenants agree to this
Control and cost transparency: a national retailer would rather manage its own store's taxes, insurance, and repairs than pay a landlord's marked-up estimate of them. NNN structure is what corporate tenants prefer, not something landlords impose.
How NNN properties are priced
NNN pricing is cap-rate pricing at its purest, and the cap rate is mostly a credit spread. The same building commands wildly different pricing depending on who signed the lease and for how long: an investment-grade tenant on a 15-year absolute-net lease trades at aggressive (low) cap rates like the corporate bond it resembles; a franchisee entity on a 7-year lease trades wide. The drivers, in rough order of weight:
- Tenant credit — is the lease guaranteed by the investment-grade parent, or by a three-unit franchisee LLC? The gap between those is the gap between a bond and a bet.
- Lease term remaining — every year that burns off moves the asset from 'income stream' toward 'vacant box with a tenant in it.' The re-leasing cliff is the central risk event.
- Rent escalations — flat leases (common in some legacy retail NNN) lose real value every inflation year; the escalation schedule is the difference between real and nominal yield.
- Rent vs. market — above-market rent is unsecured tenant credit, not real estate value; if the tenant leaves, the market rent is what the building earns.
- Real estate quality — the corner, the traffic counts, the reuse profile if dark. This is fourth on the list while the lease is long, and first the day it isn't.
Underwriting: the credit, the lease, the dirt
- Underwrite the lease guarantor like a bond analyst: audited financials where available, rent coverage, industry direction (drugstores and casual dining have taught NNN buyers hard lessons), and exactly which entity signed — parent guaranty or subsidiary shell.
- Model the re-leasing cliff explicitly: probability-weight renewal, and price the downtime, tenant improvements, and market rent of the second tenant. A 6% cap with 4 years of term is not a 6% yield; it's a 4-year annuity plus a question mark.
- Value the dark building: single-tenant format risk is real — some boxes (former banks, purpose-built restaurants) re-lease hard. Replacement-tenant depth for this format in this trade area is the honest residual.
- Read the lease's fine print like the asset it is: co-tenancy clauses, early-termination rights, assignment provisions (can the credit tenant assign to a weaker operator?), and exactly who owns the roof.
- Check the financing fit: NNN's long flat leases pair naturally with long fixed debt, but flat rents against amortizing debt compress coverage over time — and lenders price short remaining term brutally.
The recurring failure mode in NNN investing is yield-shopping the cap rate: buying the 7.5% cap franchisee deal over the 5.5% investment-grade deal because the number is bigger, without pricing the credit gap that produced it. The market is reasonably efficient at this; an NNN cap rate that looks generous is usually telling the truth about something.
NNN in portfolios, funds, and raises
NNN's operational simplicity makes it the natural asset for passive-income strategies: 1031 exchange buyers exiting management-intensive properties, retirees converting equity into stable income, and net-lease funds aggregating dozens of leases into diversified income vehicles. For sponsors, that last structure is the capital-raising angle — and it comes with obligations the simplicity of the asset can obscure.
- A net-lease fund's pitch is bond-like income with real estate residuals — so disclose it in credit terms: tenant concentration, industry concentration, weighted-average lease term, and the rollover schedule. A fund with 40% of rent from one tenant is a credit position and the PPM should say so.
- Single-asset NNN syndications live and die on the re-leasing cliff relative to the hold period — align the exit before the term burns short, and show investors the math of selling at year 7 of a 15-year lease versus year 12.
- For 1031-motivated investors, NNN and DST structures intersect heavily (see our DST and 1031 guides) — know which vehicle your buyer pool actually needs.
Frequently asked questions
What is a triple net lease?
A lease in which the tenant pays base rent plus the property's taxes, insurance, and maintenance — the three 'nets.' The landlord's role reduces to collecting rent and enforcing the lease. Freestanding retail (pharmacies, fast food, dollar stores) and industrial properties commonly use NNN structures.
What's the difference between NNN and absolute net?
Many 'NNN' leases still leave the roof, structure, and sometimes parking with the landlord. An absolute-net lease transfers everything — including structural repairs and rebuild obligations — to the tenant. The label on the listing doesn't decide this; the lease document does, and the difference can be six figures on an older building.
Why are triple net properties priced like bonds?
Because the investment is substantially a claim on a tenant's contractual payments for a fixed term. Pricing therefore keys on tenant credit quality, remaining lease term, and escalations — an investment-grade tenant on a long lease trades at a low cap rate like a corporate bond, while a franchisee on a short lease trades wide to compensate for the credit and re-leasing risk.
What are the main risks of NNN investing?
Tenant credit (the lease is only as good as the entity that signed it), the re-leasing cliff when the term expires (downtime, re-tenanting costs, and market rent below contract rent), flat escalations losing real value to inflation, and single-tenant format risk — some purpose-built boxes are genuinely hard to re-lease. The building's value dark is the honest floor.
Is a triple net lease good for landlords or tenants?
Both, differently: landlords get predictable net income without operational burden; tenants get control of their own operating costs without landlord markups. The structure is standard for corporate retail tenants. For investors, the trade is simplicity and stability in exchange for concentrated exposure to one tenant's credit.
