Net Lease

A net lease is a commercial lease in which the tenant pays base rent plus some or all of the property expenses, meaning taxes, insurance, and maintenance, rather than the landlord absorbing them. The tenant covers costs "net" of the base rent. The three standard forms, single, double, and triple net, differ by how many expense categories the tenant carries.

How Does a Net Lease Work?

A net lease works by unbundling property operating costs from base rent and passing named categories to the tenant. The tenant pays a lower base rent than a comparable gross lease, then reimburses the landlord for specified expenses. The count of "nets" defines the type: one net is taxes, two adds insurance, three adds maintenance. More nets shift more risk to the tenant.

Per Corporate Finance Institute and LoopNet, net leases are the most common structure in single-tenant commercial real estate, and terms often run 10 to 15 years or longer. The landlord favors the structure because it converts a variable expense stream into tenant-borne cost, producing a more predictable net return.

Because the tenant absorbs cost categories that would otherwise be the landlord's, base rent under a net lease is quoted lower than the all-in figure. An operator comparing two listings must add the expense pass-through to the net rent before the numbers are comparable.

Why Net Lease Matters

A net lease matters because it determines who bears the risk of rising operating costs over a long term. Under a net lease, expense inflation in taxes, insurance, and maintenance flows to the tenant, so the landlord's yield is insulated. For the tenant, an uncapped net lease turns a fixed occupancy cost into a variable one that can climb each year.

Per Corporate Finance Institute, landlords accept lower base rent under a net lease in exchange for shedding expense responsibility, which raises the effective rate of return on the investment. The tradeoff is asymmetric: a landlord with a triple net tenant carries almost no operating risk, while the tenant absorbs tax reassessments, insurance spikes, and repair bills.

The quotable point for an operator: in a net lease the base rent is only part of the cost, and the "nets" can move the true occupancy figure by several dollars per square foot each year.

Example

A retail tenant leases 3,000 square feet at $20.00 per square foot base rent on a triple net lease. Using representative pass-through figures, taxes run $3.00 per square foot, insurance $0.50, and maintenance $2.00, a combined $5.50 net charge. The tenant's total occupancy cost is base rent plus the nets.

The tenant's all-in cost is $25.50 per square foot, or $76,500 a year, not the $20.00 base rent on the listing. Per Q1 2026 market data cited by CommercialLeaseCost, net charges commonly run $7 to $19 per square foot depending on metro, so the pass-through can rival the base rent itself.

Variations and Edge Cases

A net lease is not one contract but a family of them, and the count of nets plus any caps determines the tenant's true exposure. The same building can be offered as N, NN, or NNN, and a bond lease strips out even the landlord's structural duties. The table below covers the variants an operator should confirm before signing.

The most common mistake is reading base rent as total cost. A low net rent can hide a high expense load, especially in high-tax metros. Always add the pass-through to the base rent before comparing a net lease against a gross lease.

Net Lease vs Gross Lease

A net lease is often confused with a gross lease, and both quote a base rent, but they assign operating expenses in opposite directions. Under a net lease the tenant pays base rent plus named property expenses, so the landlord's yield is shielded from cost growth. Under a gross lease the tenant pays one flat rent and the landlord absorbs the operating costs.

Per The Motley Fool, the distinction is which party carries expense risk. A net lease shifts that risk to the tenant and quotes a lower base rent to compensate, while a gross lease bundles expenses into a single higher rent. A tenant wanting cost certainty prefers a gross lease; a landlord wanting a predictable net return prefers a net lease.

Frequently Asked Questions

What is a net lease in commercial real estate?A net lease is a commercial lease in which the tenant pays base rent plus some or all property expenses, meaning taxes, insurance, and maintenance. The tenant covers costs net of the base rent, and the number of expense categories carried defines whether the lease is single, double, or triple net.

What are the three types of net leases?The three types are single net (N), where the tenant pays property taxes; double net (NN), where the tenant adds insurance; and triple net (NNN), where the tenant adds maintenance. Each step passes another operating-expense category from the landlord to the tenant.

Is base rent the tenant's total cost under a net lease?No. Under a net lease the tenant pays base rent plus the net expenses, so total occupancy cost is higher than the quoted base rent. In some metros the pass-through can rival the base rent, so the nets must be added before comparing listings.
