Debt-Service Coverage Ratio

Debt-Service Coverage Ratio (DSCR) measures your ability to cover debt payments with operating income. Formula: DSCR = Net Operating Income ÷ Total Debt Service. For rental properties, it represents net rental income divided by annual loan payments. A ratio of 1.0 indicates income exactly covers payments; 1.25 or higher is considered healthy. Most lenders require 1.20–1.25 minimum for real estate loans.

  • DSCR = Net Operating Income ÷ Total Debt Service
  • For rentals: DSCR = Net Rental Income ÷ Annual Debt Payments
  • Most lenders require a minimum of 1.20–1.25
  • DSCR of 1.50+ earns the best rates
  • Higher DSCR can lower your interest rate by 1–2%

DSCR Formula

DSCR = Net Operating Income ÷ Total Debt Service

For rental properties: DSCR = Net Rental Income ÷ Annual Debt Payments

DSCR Calculation Example

Annual Gross Rent: $3,000/month × 12 = $36,000
Annual Expenses: $9,480 (property taxes, insurance, maintenance, vacancy)
Net Rental Income: $26,520
Annual Debt Payments: $20,000
DSCR = 1.33 — Loan approved

What DSCR Means

  • 1.50+: Excellent cash flow with best available rates.
  • 1.25–1.50: Good cash flow; meets most lender requirements with competitive rates.
  • 1.20–1.25: Minimum threshold; may require higher down payment.
  • Below 1.20: Not qualified; loan typically denied.

How Lenders Use DSCR

  • Approval decisions based on 1.20–1.25 minimum threshold.
  • Higher ratios receive better interest rates (potential 1–2% reduction).
  • Impacts Loan-to-Value ratios and total loan amounts.

How to Improve Your DSCR

  1. Increase rental income through higher rents or additional income streams.
  2. Reduce operating expenses.
  3. Increase down payment to lower the loan amount.
  4. Negotiate better loan terms with your lender.

Frequently asked questions

What's a good DSCR ratio?
A ratio of 1.50+ is excellent; 1.20–1.25 meets minimum lender requirements.
How is DSCR different from debt-to-income ratio?
DSCR measures property income vs property debt payments. Debt-to-income (DTI) measures personal income vs personal debt payments.
Can I get a loan with DSCR below 1.0?
Very unlikely, as this indicates rental income doesn't cover loan payments.
Do I need existing rental income?
Lenders can use market rent estimates for new purchases.
