An NNN lease, short for triple net lease, is a commercial lease structure where the tenant pays the base rent plus the three major property expenses: real estate taxes, building insurance, and common area or exterior maintenance. The landlord still owns the real estate, but the ongoing cost of holding it shifts substantially to the tenant, which is the entire appeal of the structure for a Kansas City owner who wants a more passive holding.
The Three Nets, Spelled Out
Each net refers to one expense category the tenant reimburses or pays directly. The first net covers property taxes, the second covers building insurance premiums, and the third covers common area maintenance, which includes parking lot upkeep, landscaping, and shared utilities for a multi-tenant property. A lease that includes all three is triple net; a lease that shifts only one or two of these back to the landlord is typically called single net or double net instead.
A double net lease, sometimes written as NN, usually leaves common area maintenance with the landlord while the tenant still reimburses taxes and insurance, which is a meaningfully different economic deal than triple net even though the two terms get used loosely and sometimes interchangeably in casual conversation.
Where NNN Sits Against Gross and Modified Gross Leases
A gross lease works the opposite direction: the tenant pays one flat rent number and the landlord covers taxes, insurance, and maintenance out of that rent. A modified gross lease sits in between, with some expenses shared. Most Kansas City office space still leases on a modified gross or full-service basis, while retail pads and single-tenant industrial buildings lean heavily toward triple net, which is part of why the structure is so associated with those two property types locally.
Multi-tenant retail centers occasionally use a hybrid where the landlord quotes a base rent plus a separate CAM, tax, and insurance reimbursement billed monthly, functioning economically like triple net even though the lease itself may not use that exact label.
Absolute Net Versus What Most Leases Actually Say
Absolute triple net pushes even roof and structural replacement onto the tenant, which is the cleanest version of the structure from a landlord's perspective but is not the default. Many Kansas City net lease documents keep roof and structure with the landlord even while the tenant pays taxes, insurance, and CAM, so the word triple net on a listing sheet does not by itself answer who pays for a new roof. That answer lives in the lease exhibit, and a buyer who skips reading it is accepting an unknown liability sight unseen.
Why the Structure Matters for an Exchange Buyer
An investor coming out of a management-heavy asset, such as a multi-tenant apartment building with turnover and maintenance calls, often targets triple net specifically because the landlord's operating role shrinks to collecting rent and monitoring the tenant's compliance rather than running the building. That lighter role is a genuine tradeoff, not a free upgrade: rent typically grows more slowly than in a property where the landlord retains more control, and the investor's return depends heavily on the tenant's ongoing ability to pay.
A qualified intermediary handling a 1031 exchange does not evaluate lease structure directly, but the timeline pressure of the 45-day identification window means a buyer benefits from understanding net lease terms before searching Kansas City listings rather than learning them mid-negotiation.
Common Questions
What three expenses does a tenant pay under a triple net lease?
Real estate taxes, building insurance premiums, and common area maintenance, in addition to base rent. These are the three nets that give the lease structure its name.
Does a triple net lease mean the landlord has zero expenses?
Not necessarily. Many triple net leases still leave roof and structural replacement with the landlord unless the lease is specifically written as absolute net. The lease exhibit determines which party carries that cost.
How is a triple net lease different from a gross lease?
Under a gross lease the tenant pays one flat rent figure and the landlord covers taxes, insurance, and maintenance from that rent. A triple net lease shifts those three expenses back to the tenant on top of a typically lower base rent.
Are Kansas City retail properties usually triple net?
Single-tenant retail pads and free-standing buildings in the metro are commonly leased triple net, while multi-tenant office space here more often uses a modified gross or full-service structure.
Why do exchange buyers often look for triple net property specifically?
The lighter ongoing management role suits an investor exiting a more operationally demanding property. It is a tradeoff rather than a pure upgrade, since rent growth and control both typically shrink along with the landlord's responsibilities.
