In a gross lease the tenant pays one rent number and the landlord pays the property's operating expenses out of it. In a net lease the tenant pays a lower base rent plus some or all of the property costs on top: taxes, insurance, and maintenance. Neither structure is inherently cheaper. The gross rent already contains the landlord's estimate of those costs plus a cushion for being wrong. What changes between the two is who carries the risk when expenses move.

What a gross lease is
A gross lease, sometimes called a full service lease, bundles occupancy into a single rent payment. The landlord pays property taxes, building insurance, common area maintenance, and usually utilities and janitorial from that rent. The tenant writes one check and does not see an operating expense statement.
Landlords price gross leases defensively. Because they absorb any increase in taxes, insurance, or maintenance over the term, the quoted rent carries a margin for that exposure, plus escalations that bump the number every year whether or not costs actually rose. A tenant paying gross rent is buying certainty, and certainty has a price.
Pure gross leases are rarer than the term suggests. Most office leases marketed as gross are in fact modified gross: the landlord covers operating expenses up to a base year, and the tenant pays its share of increases above it. That base year mechanic, and where it goes wrong, is covered in our guide to the modified gross lease.
What a net lease is
In a net lease the tenant pays a base rent that is "net" of property costs, then reimburses the landlord for those costs separately. There are three standard versions, and the difference is simply how many cost categories move to the tenant.
| Type | Tenant pays, on top of base rent |
|---|---|
| Single net (N) | Property taxes |
| Double net (NN) | Property taxes and building insurance |
| Triple net (NNN) | Taxes, insurance, and common area maintenance |
| Absolute net | Everything, including roof, structure, and capital repairs |
Triple net is the common one, especially in retail and single-tenant industrial. The tenant pays base rent plus its pro-rata share of the property's operating costs, billed monthly as an estimate and trued up after year end. The full mechanics, including where the "net" stops, are in our triple net lease guide.
Absolute net goes one step further and hands the tenant structural and capital obligations too. It shows up in sale-leasebacks and credit-tenant deals, where the tenant is effectively an owner without title, and it is the structure investors mean when they call a property "truly passive."
How to compare a gross quote against a net quote
Brokers quote gross and net rents in the same units, dollars per square foot per year, which makes them look comparable when they are not. To compare honestly, build the gross equivalent of the net deal:
- Start with the NNN base rent per square foot.
- Add the current estimated operating expenses per square foot, often called the NNN load or CAM estimate.
- Add anything the net lease pushes to the tenant that the gross lease covers: utilities, janitorial, interior HVAC service.
- Compare that total to the gross rent for the same year.
A quick example. Suite A is quoted at $32 per square foot gross. Suite B is quoted at $22 per square foot NNN with an estimated $9 load. Suite B looks $10 cheaper on the headline and is roughly $1 cheaper once loaded, before you account for the fact that the $9 is an estimate the tenant will be trued up against, and the $32 is not.
That gap is the whole decision. Ask for the last three years of actual operating expenses on the net deal, not just this year's estimate. If taxes were recently reassessed after a sale, or the property is about to repave a parking field, the load you were quoted is not the load you will pay.
Which lease type favors the landlord, and which favors the tenant?
Net leases favor the landlord on risk. Costs pass through, so net operating income is insulated from inflation in taxes, insurance premiums, and maintenance. That predictability is why net-leased assets trade at tighter cap rates than gross-leased ones with similar credit.
Gross leases favor the tenant on budgeting. One number, no reconciliation, no year-end surprise. Small businesses and tenants without a real estate function usually prefer it, and pay a premium for the privilege.
Neither is automatically better. What matters is whether the risk you take is priced fairly. A tenant that accepts a net lease should negotiate protections: a cap on controllable expenses, an exclusions list that keeps capital items out, a gross-up provision, and an audit right with a workable window. A tenant that accepts a gross lease should look hard at the annual escalator, because a 3 percent bump on an all-in rent compounds faster than expenses usually do.
Where the money actually leaks: the pass-through clause
Most disputes on net leases are not about the base rent, which is unambiguous. They are about what the landlord is allowed to pass through. Roof replacement billed as maintenance instead of capital. Management fees charged at a percentage of gross receipts rather than a fixed amount. Occupancy grossed up incorrectly in a half-empty building. A cap that the lease says is cumulative and the statement treats as annual.
Landlords running these numbers need the same discipline in reverse: property-level costs have to be captured, coded, and allocated correctly before they can be billed, which is why operators increasingly push vendor bills through automated accounts payable rather than reconciling paper invoices at year end. Whichever side you sit on, the reconciliation only holds up if the expense detail is clean and the lease language is in front of you.
Our CAM reconciliation guide walks through how to test a statement line by line, and lease audit covers the recovery process when the numbers do not hold up.
Reading the structure out of the lease
You cannot tell a gross lease from a net lease by its title page. Documents labeled "Standard Office Lease" run the full spectrum, and the actual structure lives in the operating expense, tax, and insurance articles, then gets modified by an amendment three years later that nobody re-read.
The terms that settle the question:
- The base rent and whether it is stated as net
- The operating expense article: base year, pro-rata share, cap, gross-up, exclusions
- The tax and insurance articles, and whether either is separately reimbursed
- Who holds repair and replacement obligations for roof, structure, and HVAC
- Utilities and services: separately metered, or included
Leaseabstracts pulls exactly these fields out of each lease and its amendments into a structured abstract, with every value linked back to the clause it came from, so a portfolio of mixed gross and net leases can be compared on the same terms.

Gross lease vs net lease FAQ
What is the difference between a gross lease and a net lease?
In a gross lease the tenant pays a single rent and the landlord covers property taxes, insurance, and maintenance out of it. In a net lease the tenant pays a lower base rent plus some or all of those costs directly. The practical difference is who absorbs the risk when operating expenses rise during the term.
Is a gross lease more expensive than a net lease?
The quoted gross rent is higher, but not necessarily the total cost. Load the net lease with its estimated operating expenses and the two often land close together. The gross rent includes a premium for the landlord carrying expense risk; the net rent shifts that risk, and any overrun, to the tenant.
What is the difference between a gross lease and a triple net lease?
A gross lease bundles taxes, insurance, and common area maintenance into one rent paid by the tenant to the landlord. A triple net lease separates all three and bills them to the tenant on top of base rent, reconciled annually against actual costs. Gross gives budget certainty; triple net gives a lower headline rent with variable add-ons.
Which lease type is better for a tenant?
A gross lease suits tenants who value predictable occupancy cost and have no real estate staff to police reconciliations. A net lease can be cheaper for tenants with the sophistication to negotiate caps, exclusions, and audit rights, and to check the annual statement. Compare the loaded net cost against the gross rent before deciding.
What does NNN mean in a lease quote?
NNN means triple net: the quoted rent is base rent only, and the tenant additionally pays its pro-rata share of property taxes, building insurance, and common area maintenance. Ask for the current NNN load per square foot and the last three years of actual expenses, since the estimate is what gets billed and the actual is what gets trued up.
What is the difference between a gross lease and a modified gross lease?
A full gross lease leaves every operating cost with the landlord for the whole term. A modified gross lease sets a base year: the landlord absorbs expenses up to that level, and the tenant pays its share of increases above it. Modified gross is far more common in office leasing than a true full gross structure.
