Definition
The Debt Service Coverage Ratio (DSCR) measures how many times a property's net operating income (NOI) covers its annual mortgage payments (principal + interest). A DSCR of 1.0 means the property breaks even — income exactly covers debt. Above 1.0 means positive coverage; below 1.0 means the property cannot cover its own mortgage from rental income alone.
The DSCR (Debt Service Coverage Ratio) Formula
Variables explained:
NOI is annual net operating income (rent minus operating expenses, before mortgage). Annual Debt Service is 12 × your monthly mortgage payment (principal + interest only — not taxes/insurance if those are already in NOI).
DSCR (Debt Service Coverage Ratio) Example with Real Numbers
Your rental property has a NOI of $18,000/year. Your mortgage payment is $1,200/month ($14,400/year). DSCR = $18,000 / $14,400 = 1.25. This means the property generates 25% more income than needed to cover the mortgage — a healthy cushion that most lenders require.
Why DSCR (Debt Service Coverage Ratio) Matters for Investors
DSCR is the primary metric lenders use to approve investment property loans. Most require a minimum DSCR of 1.20–1.25. If your DSCR falls below 1.0, you have negative leverage — you're supplementing rental income with personal funds every month to make the mortgage payment. Tracking DSCR helps you spot properties where the math just doesn't work at a given price.

Frequently Asked Questions
What DSCR do lenders require?
Most conventional and DSCR-specific loan programs require a minimum of 1.20–1.25. Some lenders allow as low as 1.0 for strong borrowers with large reserves, but this offers zero cushion.
What is DSCR loan?
A DSCR loan qualifies borrowers based on property income rather than personal income. Lenders verify the rental income covers the mortgage by a required ratio (typically 1.20+), making them popular with self-employed investors and those with complex tax returns.
How do I improve my DSCR?
Increase rent, reduce operating expenses, make a larger down payment to lower the monthly mortgage, or choose a longer loan term to reduce monthly debt service.
Is a higher DSCR always better?
From a risk standpoint, yes — a higher DSCR means more income cushion. But an extremely high DSCR might mean you're leaving leverage on the table or could deploy capital in a higher-returning investment.
