Net vs Gross Leases — Who Carries the Building

Every commercial lease answers one question — who carries the building’s costs — and the net/gross spectrum is just the range of answers. Gross: the landlord, priced into fatter rent. Net: the tenant, in escalating degrees (single, double, triple). Everything else is detail.

The risk transfer underneath

Gross structures leave expense volatility with the owner: a tax reassessment, an insurance repricing, a utility spike land on the landlord’s P&L between lease renewals. Net structures transfer that volatility to tenants — which is why net rent is lower per foot but worth more per dollar to income buyers: it’s pre-insulated. The 2022-26 insurance market made this vivid; gross-lease owners in coastal states absorbed premium doublings that NNN owners merely watched pass through.

Pricing logic across the spectrum

Appraisers and buyers normalize everything to net-equivalent income: a gross building’s value starts from rent minus the owner-paid expense load and reserves for its volatility. Two identical buildings — one gross at $30, one NNN at $22 with $8 of pass-throughs — should price near each other, and any spread reflects who bears expense risk plus management burden. When the market misprices this (it does), the arbitrage belongs to whoever converted the structures honestly with something like our lease-cost calculator.

Which fits whom

Gross and full-service suit operators who manage buildings for a living and tenants who want one predictable number. Net suits passive capital and expense-controlling tenants — the entire single-tenant market runs on it for both reasons at once. The mismatch cases fund everyone else’s returns: passive buyers holding gross buildings they can’t operate, and operators paying net-lease prices for jobs they didn’t need to outsource.
