If you’re applying for a rental property loan—especially a DSCR loan—there’s one number that can make or break your approval:
DSCR, or Debt Service Coverage Ratio.
Unlike conventional loans that focus on your personal income, DSCR loans are underwritten based on your property’s income performance. That means lenders want to see one thing: cash flow coverage.
In this guide, we’ll break down what DSCR is, how to calculate it, what lenders expect, and how you can improve your ratio to increase your chances of approval.
What Is DSCR?
DSCR stands for Debt Service Coverage Ratio. It measures whether a rental property generates enough income to cover its loan payments.
🧮 DSCR Formula:
DSCR = Net Operating Income (NOI) ÷ Annual Debt Service
- NOI = Gross rental income – operating expenses
- Annual Debt Service = Total yearly loan payments (principal + interest)
