Gross Lease

What Is a Gross Lease?

A gross lease, sometimes called a full-service lease, is a rental agreement where the tenant pays one fixed rental amount and the landlord is responsible for all property operating expenses. The tenant's financial obligation is simple and predictable: pay rent. Everything else — property taxes, insurance, maintenance, repairs, and often utilities — falls on the landlord. Virtually every residential rental in America operates on a gross lease basis. In commercial real estate, gross leases are most common in multi-tenant office buildings where dividing expenses among tenants would be impractical.

Gross Lease vs. NNN Lease

The fundamental difference is who bears the expense risk. In a gross lease, the landlord absorbs all operating cost increases. If property taxes jump 20% or insurance premiums spike after a hurricane, the landlord's NOI decreases while the tenant's rent stays the same. In a NNN lease, those increases are passed directly to the tenant. For this reason, gross lease rents are significantly higher than NNN rents on a per-square-foot basis — the higher rent compensates the landlord for taking on expense risk. A space that might lease for $15/SF NNN could lease for $25/SF gross, with the $10 differential covering estimated expenses plus a risk margin.

Modified Gross Leases

Many commercial leases fall somewhere between a pure gross lease and a pure NNN lease. A modified gross lease assigns specific expense categories to the tenant while the landlord retains others. Common structures include the tenant paying utilities and janitorial services while the landlord covers taxes, insurance, and structural maintenance. Another variation is the "base year stop" — the landlord pays all expenses in the first year, establishing a baseline, and the tenant pays their proportional share of any increases above that baseline in subsequent years. Modified gross leases attempt to balance simplicity for the tenant with expense protection for the landlord.

Expense Risk for the Landlord

The primary challenge of gross leases is that the landlord bears all expense risk. Property taxes can increase unpredictably due to reassessments. Insurance premiums fluctuate with claims history and market conditions. Maintenance costs escalate as buildings age. Utility costs vary with weather and energy prices. If you sign a 5-year gross lease and expenses increase 3% annually while rent escalates only 2%, your NOI erodes every year. This is why accurate expense budgeting is critical before setting gross lease rents. Underestimate expenses and your seemingly profitable property becomes a money loser.

Budgeting and Rent Setting

Setting the right gross lease rent requires detailed expense forecasting. Start with current actual expenses and project increases over the lease term. Add a margin for unexpected costs — at least 5–10% above your baseline projection. Factor in the target NOI you need to achieve your return requirements. The resulting figure is your minimum gross lease rent. Compare this against market rents for similar properties. If the market rent supports your expense projections with adequate margin, the deal works. If market rents are below your calculated minimum, the property cannot generate acceptable returns under a gross lease structure and you should consider a different property or a modified lease structure.

Gross Leases in Residential Investing

For residential rental investors, the gross lease is simply how the business works — tenants expect to pay one rental amount and have the landlord handle everything else. This means residential investors must be disciplined about expense management. Track every expense category monthly. Shop insurance annually to ensure competitive rates. Appeal property tax assessments when values are overstated. Perform preventive maintenance to avoid expensive emergency repairs. Build CapEx reserves for major replacements. And raise rents annually to at least keep pace with expense increases. The investors who thrive with gross leases are those who manage expenses as aggressively as they pursue income growth.
