Debt Service Coverage Ratio (DSCR)
DSCR asks whether property income provides enough room to pay the scheduled debt.
Definition
Debt Service Coverage Ratio equals underwritten NOI divided by annual debt service. If NOI is $500,000 and annual principal and interest payments total $400,000, DSCR is 1.25x. The property produces $1.25 of NOI for every $1.00 of scheduled debt service.
Beginner Explanation
Imagine your monthly income is $1,250 and a required payment is $1,000. You can make the payment and have $250 of cushion. A 1.00x ratio means income only equals the payment, leaving no operating buffer. Below 1.00x means the measured income is insufficient and another cash source would be needed.
Professional Explanation
The apparent simplicity of DSCR hides two underwriting judgments: which NOI is accepted and how debt service is calculated. A lender may reduce income, normalize expenses, include vacancy, or use a stressed interest rate and amortizing payment. Different lenders can therefore calculate different ratios for the same property. Required minimums vary by asset, loan program, sponsor, and risk. DSCR may size the loan more tightly than LTV, particularly when debt costs are high or property yields are low.
Why It Matters
DSCR measures repayment cushion, not investment quality by itself. A high ratio may indicate strong income relative to debt, but it can also reflect very low leverage. A lower ratio may expose the loan to modest income declines. Investors use DSCR to understand downside tolerance, while lenders use it to protect payment capacity and determine proceeds.
Real-World Example
A property has $480,000 of lender-underwritten NOI. At $360,000 annual debt service, DSCR is 1.33x. If NOI falls 10% to $432,000, DSCR falls to 1.20x. The loan payment did not change, but the protection above it became materially thinner.
Common Mistakes
- Using seller NOI without lender adjustments.
- Confusing interest expense with total debt service.
- Treating a minimum DSCR as proof that a deal is safe.

Practical Exercise

债务偿付覆盖率（DSCR）
DSCR 衡量物业收入是否为计划债务本息提供足够缓冲。
定义
债务偿付覆盖率等于承销 NOI 除以年度债务本息。如果 NOI 为 50 万美元，年度本金与利息合计 40 万美元，DSCR 就是 1.25 倍，即每 1 美元计划债务本息由 1.25 美元 NOI 支持。
先用简单语言理解
假设月收入为 1,250 美元，必须支付的款项为 1,000 美元。你能够付款，并保留 250 美元缓冲。1.00 倍表示收入刚好等于付款，没有运营余量；低于 1.00 倍则表示所衡量的收入不足，需要其他现金来源补足。
专业解释
DSCR 表面简单，却包含两个重要承销判断：认可哪一种 NOI，以及如何计算债务本息。贷款机构可能调低收入、标准化费用、计入空置，或使用压力利率和摊销付款。同一物业在不同贷款机构手中可能得到不同比率。最低要求会随资产、贷款项目、借款人和风险变化。尤其当债务成本较高或物业收益率较低时，DSCR 对贷款额度的限制可能比 LTV 更严格。
为什么重要
DSCR 衡量还款缓冲，但不能单独证明投资质量。较高比率可能表示收入相对于债务很强，也可能只是因为杠杆很低；较低比率则可能使贷款对轻微收入下降更加敏感。投资人用 DSCR 理解下行情景承受能力，贷款机构则用它保护还款能力并确定贷款额度。
实际案例
一项物业经贷款机构承销的 NOI 为 48 万美元，年度债务本息为 36 万美元，DSCR 为 1.33 倍。如果 NOI 下降 10% 至 43.2 万美元，DSCR 会降至 1.20 倍。贷款付款没有变化，但其上方的保护缓冲明显变薄。
常见错误
- 未经贷款机构调整便使用卖方 NOI。
- 把利息费用与全部债务本息混为一谈。
- 把达到最低 DSCR 当作交易安全的证明。

练习
以 62.5 万美元 NOI 和 50 万美元债务本息计算 DSCR；再把 NOI 降低 15%，说明贷款机构的保护发生了什么变化。
