Key takeaways

  • DSCR compares net operating income with annual debt service.
  • A higher DSCR gives more room for income volatility before debt coverage becomes stressed.
  • Loan amount, interest rate, amortization, rent, occupancy, and expenses can all change DSCR.

What DSCR measures

DSCR compares net operating income with annual debt service. A DSCR above 1.0x means income exceeds debt service, while a ratio below 1.0x indicates a shortfall.

Why lenders care about DSCR

Lenders use DSCR to evaluate repayment capacity and downside protection. A higher DSCR generally indicates more room for income volatility before debt coverage becomes stressed.

How assumptions affect DSCR

Rent, occupancy, operating expenses, loan amount, interest rate, and amortization can all materially change DSCR.

How to apply it

Practical review checklist

  • Calculate stabilized NOI before evaluating debt capacity.
  • Review DSCR after changes to leverage, interest rate, amortization, rent, and vacancy.
  • Use DSCR together with LTV/LTC, breakeven occupancy, and return metrics.

Review risks

Common mistakes to avoid

  • Comparing DSCR across deals without checking loan structure and amortization.
  • Ignoring how occupancy, expenses, and interest rates can quickly reduce coverage.

FAQ

Common questions

What is a good DSCR?

It depends on lender standards, asset type, market, and risk profile. Many lenders look for a cushion above 1.0x rather than mere break-even coverage.

Can DSCR change over time?

Yes. DSCR can improve or weaken as income, expenses, interest rates, and debt service change.
