Discounted Cash Flow (DCF)
DCF values a sequence of future cash flows by translating them into today's dollars.
Definition
Discounted cash flow analysis projects future property cash flows and sale proceeds, then discounts each amount to present value using a required rate of return. It explicitly recognizes that a dollar received later is worth less than a dollar received today.
Beginner Explanation
Would you rather receive $100 today or several years from now? Most people prefer today because the money can be used and because the future is uncertain. DCF applies that idea to rent, expenses, renovations, and eventual sale. Each future dollar is reduced according to how far away it is and what return the investor requires.
Professional Explanation
A property DCF commonly models lease-level revenue, vacancy, expenses, capital expenditures, tenant improvements, leasing commissions, debt when relevant, and terminal sale value. Terminal value is often estimated by capitalizing a future NOI with an exit cap rate and subtracting selling costs. The discount rate reflects required return and risk. DCF is powerful because it handles changing cash flows, but the detail can create false precision. Rent growth, downtime, exit cap, discount rate, and sale timing often drive the result more than spreadsheet complexity.
Why It Matters
DCF is useful for value-add assets, lease rollover, development, renovations, or any investment whose cash flows cannot be represented by one stable year. It also forces timing assumptions into view. However, a model is a structured scenario, not a prediction. Investors should run sensitivities and downside cases instead of relying on one output.
Real-World Example
An asset produces low cash flow during two renovation years, stronger income after lease-up, and sale proceeds in year five. Direct capitalization of year-one NOI may understate the plan, while DCF can represent the cost, delay, stabilization, and exit separately.
Common Mistakes
- Treating model output as a certain forecast.
- Using aggressive growth with an aggressive exit value.
- Ignoring selling costs and capital expenditures.

- Broker
- Five- or ten-year projection
- Interview
- DCF discounts projected cash flows and terminal value, so I test its major assumptions.

Practical Exercise
List five annual cash flows for a renovation case. Identify which year includes the largest capital need and which assumptions determine terminal value.

折现现金流（DCF）
DCF 把一系列未来现金流折算为今天的价值。
定义
折现现金流分析预测物业未来现金流与出售收入，再使用必要回报率把每一笔金额折算为现值。它明确承认未来收到的一美元低于今天收到的一美元。
先用简单语言理解
你更愿意今天收到 100 美元，还是几年后收到？多数人选择今天，因为资金可以立即使用，未来也存在不确定性。DCF 把这个逻辑用于租金、费用、翻修和最终出售。每一笔未来资金都会根据距离今天的时间和投资人要求的回报进行折减。
专业解释
物业 DCF 通常模拟租约层面的收入、空置、费用、资本性支出、租户装修、租赁佣金、相关债务和终值出售收入。终值常用退出资本化率资本化未来 NOI，并扣除出售成本。折现率反映必要回报与风险。DCF 能处理变化的现金流，但大量细节也可能制造虚假精确感。租金增长、空置期、退出资本化率、折现率和出售时间通常比表格复杂程度更能决定结果。
为什么重要
DCF 适用于增值型资产、租约到期、开发、翻修，或任何无法用单一稳定年度代表现金流的投资。它还会迫使分析者明确时间假设。但模型是结构化情景，不是预测。投资人应进行敏感性与下行情景分析，而不是依赖一个结果。
实际案例
一项资产在前两年翻修期间现金流较低，出租完成后收入增强，并在第五年出售。直接资本化第一年 NOI 可能低估计划，而 DCF 可以分别反映成本、延迟、稳定化和退出。
常见错误
- 把模型结果当作确定预测。
- 同时使用激进增长和激进退出价值。
- 忽略出售成本和资本性支出。
相关概念
- Present value
- Discount rate
- Terminal value
- Exit cap rate

- 五年或十年预测
- Interview
- DCF 折现预计现金流和终值，因此我会检验其中最重要的假设。
常用缩写
- DCF — Discounted Cash Flow
- PV — Present Value
- TV — Terminal Value
