Rent, Revenue, and Property Income
Before calculating returns, learn where a property's money actually comes from.
Definition
Property income is the money generated by ownership or operation of real estate. It may include base rent, percentage rent, expense reimbursements, parking, storage, signage, service charges, hotel room revenue, and other recurring or occasional payments.
Beginner Explanation
The rent printed in a lease is not always the same as money collected. A tenant may receive free rent, pay late, reimburse some expenses, or leave before the lease ends. A building may also earn money from parking or storage. The first job is therefore to list every income source and ask whether it is contractual, collected, sustainable, and connected to extra costs.
Professional Explanation
Underwriting separates potential income from effective income. Scheduled rent assumes occupied space pays according to contract. Vacancy, credit loss, concessions, and collection problems reduce that amount. Reimbursements must be matched with the expenses they offset, while temporary or nonrecurring income may receive little weight. Analysts also study lease expiration dates because current revenue can be strong while future revenue is exposed to rollover. A clean analysis therefore reconciles the lease, rent roll, bank deposits, and operating statements instead of relying on a single document.
Why It Matters
Every major CRE metric begins with income. Overstated revenue inflates NOI, value, loan proceeds, and projected returns. Careful income review also reveals tenant concentration, dependence on one lease, and whether growth comes from genuine demand or an assumption in a spreadsheet.
Real-World Example
A property lists $300,000 of annual rent, but one vacant unit represents $30,000 and another tenant receives $10,000 of concessions. Before reimbursements, effective rent is closer to $260,000—not $300,000.
Common Mistakes
- Using asking rent as if it were collected rent.
- Counting reimbursements without the related expense.
- Treating temporary income as permanent.

租金、营业收入与物业收入
计算回报之前，先弄清物业的钱究竟从哪里来。
定义
物业收入是持有或运营不动产所产生的资金，包括基本租金、提成租金、费用报销、停车、仓储、广告位、服务费、酒店客房收入以及其他经常性或偶发性付款。
先用简单语言理解
租约中写明的租金并不一定等于实际收到的钱。租户可能享有免租期、延迟付款、报销部分费用，或在租约到期前离开。建筑也可能从停车或仓储获得收入。因此第一步是列出所有收入来源，并判断它是否有合同支持、是否实际收取、能否持续，以及是否伴随额外成本。
专业解释
承销会区分潜在收入与有效收入。合同租金假设已出租空间按约付款，而空置、信用损失、优惠和收款问题会降低实际收入。费用报销应与其抵消的支出相匹配；临时或非经常性收入通常权重较低。分析人员还会研究租约到期时间，因为当前收入可能很强，但未来收入可能面临集中续租风险。一份清晰的分析会交叉核对租约、租金表、银行入账和运营报表，而不是只依赖某一份文件。
为什么重要
几乎所有重要的商业地产指标都从收入开始。高估收入会同时抬高 NOI、估值、贷款额度和预计回报。仔细审查收入还能揭示租户集中度、对单一租约的依赖，以及增长究竟来自真实需求还是表格中的假设。
实际案例
一项物业列示年度租金 30 万美元，但一个空置单元对应 3 万美元，另一名租户享有 1 万美元优惠。在计入费用报销前，有效租金更接近 26 万美元，而不是 30 万美元。
常见错误
- 把报价租金当作已收租金。
- 只计算费用报销，却忽略相关支出。
- 把临时收入当作永久收入。
