DSCR Explained
The Debt Service Coverage Ratio tells you — and your lender — whether a property generates enough income to safely cover its mortgage. Here is how to calculate it and what to target.
The formula
Where:
- Annual NOI
- Gross rent × (1 − vacancy rate) − management − maintenance − CapEx − taxes − insurance
- Annual Debt Service
- 12 × monthly mortgage payment (principal and interest)
Example:
- Annual NOI = $24,000
- Annual Debt Service = $18,000
- Step 1: DSCR = 24,000 ÷ 18,000
- Step 2: DSCR = 1.33
A DSCR of 1.33 means the property generates 33% more income than needed to cover its debt payments — 13 percentage points above the typical lender minimum.
DSCR examples
DSCR 1.40
Safe
40% income buffer above debt service
DSCR 1.20
Lender minimum
Most lenders require ≥ 1.20
DSCR 1.00
Break-even
Income exactly covers debt
DSCR 0.85
Negative
Property cannot cover its mortgage
Why lenders care about DSCR
Lenders use DSCR to assess risk. A property with a DSCR of 1.25 can absorb a 20% reduction in income (due to vacancy or rent decline) and still cover the mortgage. A property at 1.0 has zero margin for error.
For DSCR loan programs specifically, the property's DSCR determines approval — not the borrower's personal income or debt-to-income ratio. This makes DSCR loans popular with investors who have many properties or self-employment income.
What affects DSCR
- Rent level — Higher rent increases NOI and DSCR.
- Vacancy rate — Higher vacancy reduces effective income and DSCR.
- Operating expenses — Lower expenses increase NOI and DSCR.
- Interest rate — Higher rates increase debt service and reduce DSCR.
- Down payment — Larger down payment reduces the loan balance, lowering monthly debt service and increasing DSCR.
- Loan term — A 30-year term has lower monthly payments than a 15-year term, resulting in higher DSCR.
How to improve DSCR
If a deal's DSCR is too low:
- Negotiate a lower purchase price (reduces loan amount and monthly payment).
- Increase down payment to reduce the financed amount.
- Look for a lender with a lower rate — each 0.5% reduction in rate meaningfully improves DSCR.
- Verify that rent estimates are conservative — market rent increases directly raise NOI and DSCR.
- Reduce operating expense assumptions if they are too conservative for the specific property.
Frequently asked questions
- What is DSCR?
- DSCR (Debt Service Coverage Ratio) measures how many times a property's net operating income covers its annual mortgage payments. A DSCR of 1.25 means the property generates 25% more income than needed to pay the mortgage.
- What DSCR do lenders require?
- Most conventional lenders require a minimum DSCR of 1.20–1.25 for investment property loans. DSCR loan programs (which qualify based on property income rather than personal income) often require 1.20 or higher. Some portfolio lenders accept 1.10 or even 1.0 for strong borrowers.
- What does a DSCR below 1.0 mean?
- A DSCR below 1.0 means the property does not generate enough income to cover the mortgage. You would need to contribute cash from other income sources to make mortgage payments. Lenders typically will not approve a loan on a property with DSCR below 1.0.
- How do I improve DSCR?
- Increase NOI (raise rents, reduce vacancy, lower operating expenses) or reduce debt service (larger down payment, lower interest rate, longer loan term). A larger down payment is the most direct lever — it lowers your monthly mortgage payment without changing the property's income.
- Is DSCR the same as DSCR loan?
- No — DSCR is a metric (a ratio). A "DSCR loan" is a type of loan program where lenders qualify the loan based on the property's DSCR rather than the borrower's personal income. These loans are popular with real estate investors who have complex income or many properties.
