What is DSCR?
The Debt Service Coverage Ratio (DSCR) is the primary risk-assessment metric used by commercial lenders. It measures a commercial property's ability to cover its debt payments using exclusively its own operating income.
Unlike residential mortgages, which evaluate the borrower's personal W-2 income and DTI, commercial loans evaluate the *property's* income. If the property cannot sustain itself, the bank assumes heavy risk.
The Formula
\[ \text{DSCR} = \frac{\text{Net Operating Income (NOI)}}{\text{Annual Debt Service}} \]
Lenders' Threshold Tiers
- **DSCR < 1.0**: The property is bleeding cash. It does not generate enough income to cover the mortgage. Banks will immediately reject these loans unless the borrower is bringing massive cash reserves.
- **DSCR = 1.0**: Break-even. Every dollar of profit goes straight to the bank. Still too risky for lenders.
- **DSCR = 1.15 - 1.20**: This is the minimum threshold for 'safe' asset classes like stabilized multi-family apartment buildings.
- **DSCR = 1.25 - 1.35**: The standard threshold for riskier assets like retail strip centers, office spaces, or mixed-use properties.
- **DSCR > 1.40**: Highly conservative. Indicates immense cash flow buffers and ensures the borrower will receive the lowest possible interest rates.
