Gross, Net, and Triple-Net Leases
A lease is not only a rent number; it is an agreement about who pays which costs.
Definition
Lease structure describes how property operating expenses are divided between landlord and tenant. In a gross lease, the landlord generally pays most operating costs from the rent received. In a net lease, the tenant reimburses one or more costs. A triple-net lease usually assigns property taxes, insurance, and maintenance responsibilities to the tenant, subject to the actual contract.
Beginner Explanation
Imagine two apartments with the same monthly payment. In one, utilities and services are included; in the other, the occupant pays everything separately. The stated price is identical, but the owner's remaining income is not. Commercial leases work the same way on a larger scale. A lower rent with strong reimbursements may produce more stable NOI than a higher gross rent that leaves every rising expense with the landlord.
Professional Explanation
Labels are only starting points. Modified gross, single-net, double-net, and triple-net leases can allocate costs differently, and definitions vary across documents and markets. Analysts read the expense clauses, base-year provisions, caps, exclusions, administrative fees, audit rights, and responsibility for structural or capital work. They distinguish recoverable expenses from nonrecoverable expenses and test whether reimbursements are being billed and collected. Even a nominal NNN lease may leave the owner responsible for roof, structure, parking areas, or replacement reserves.
Why It Matters
Expense responsibility determines how revenue becomes NOI and who bears inflation risk. If taxes or insurance rise, a reimbursing tenant may absorb much of the increase; under a gross lease, the landlord may absorb it. Lease structure also changes management demands, credit exposure, and valuation comparisons. Cap rates from net-leased properties should not be applied casually to properties with materially different landlord obligations.
Real-World Example
Two stores each pay $200,000 in base rent. Store A reimburses $60,000 of taxes and insurance; Store B pays gross rent while the landlord bears those costs. Their base rent matches, but their contribution to NOI differs by approximately $60,000 before other adjustments.
Common Mistakes
- Assuming every NNN lease transfers every cost.
- Comparing base rents without expense responsibility.
- Counting recoveries without confirming billing and collection.

Practical Exercise
Compare two $100,000 leases: one gross with $35,000 landlord expenses, one net with $25,000 reimbursements and $5,000 unrecovered costs. Calculate each NOI contribution.

全包租约、净租约与三净租约
租约不只是租金数字，更是关于谁承担哪些费用的安排。
定义
租约结构说明物业运营费用如何在业主与租户之间分配。全包租约通常由业主从所收租金中支付多数运营成本；净租约由租户报销一项或多项费用；三净租约通常把地产税、保险和维护责任分配给租户，但最终仍应以具体合同为准。
先用简单语言理解
假设两套空间月租相同，一套包含水电和服务，另一套由使用者另外承担全部费用。表面价格相同，业主最终留下的收入却不同。商业租约也是同样逻辑。租金较低但费用报销充分的租约，可能比租金较高却由业主承担所有上涨费用的全包租约产生更稳定的 NOI。
专业解释
各种名称只能作为起点。修正全包、单净、双净和三净租约可能采用不同费用分配方式，不同文件和市场的定义也可能不同。分析人员会阅读费用条款、基准年度、上限、排除项目、管理费、审计权，以及结构或资本工程责任，并区分可回收费用与不可回收费用，核实报销是否真正开单并收取。即使名义上的 NNN 租约，也可能由业主负责屋顶、主体结构、停车区域或更换储备。
为什么重要
费用责任决定收入如何转化为 NOI，也决定谁承担通胀风险。地产税或保险上涨时，有报销义务的租户可能承担大部分增量；在全包租约下，则可能由业主承担。租约结构还会改变管理要求、信用风险和估值可比性。净租物业的资本化率不能随意用于业主义务明显不同的物业。
实际案例
两家商铺的基本租金均为 20 万美元。A 商铺另外报销 6 万美元地产税和保险；B 商铺支付全包租金，由业主承担这些费用。两者基本租金相同，但在其他调整前，对 NOI 的贡献相差约 6 万美元。
常见错误
- 认为所有 NNN 租约都转移了全部费用。
- 比较基本租金时忽略费用责任。
- 未确认开单和收款便计算费用回收。

- 全包租金与 NNN 租金
- Interview
- 我会阅读合同中的费用分配，而不会只依赖全包或净租标签。
常用缩写
- NNN — Triple Net
- NN — Double Net
- MG — Modified Gross
练习
比较两份 10 万美元租约：一份全包且业主承担 3.5 万费用；另一份净租，租户报销 2.5 万但仍有 5,000 美元未回收费用。计算各自对 NOI 的贡献。
