DSCR stands for Debt Service Coverage Ratio — a property's monthly rental income divided by its monthly debt obligations (principal, interest, taxes, insurance, and HOA fees). A DSCR of 1.0 means income exactly covers debt. Most DSCR lenders require a minimum of 1.0 to 1.25, meaning the property must generate at least as much rent as it costs to carry.
DSCR = Monthly Gross Rent ÷ Monthly PITI (+ HOA if applicable)
Where PITI = Principal + Interest + Taxes + Insurance
Example:
This property generates 24% more income than it costs to carry — a healthy cash flow margin for most lenders.
DSCR above 1.25: Property generates strong cash flow. Most lenders have no issue at this level. May qualify for the best rates and highest LTV.
DSCR 1.0 to 1.25: Property breaks even to modestly cash flows. Most DSCR lenders will fund in this range. Rates may be slightly higher and LTV may be lower than at 1.25+.
DSCR below 1.0 (negative cash flow): The property does not cover its own debt obligations — the borrower subsidizes the payment. Many lenders will not fund below 1.0. Some lenders have programs down to 0.75 DSCR for strong borrowers with significant equity. Below 0.75 is very uncommon.
Traditional mortgage underwriting qualifies borrowers based on personal income — W-2s, tax returns, pay stubs, debt-to-income ratio. For real estate investors, this creates a series of problems:
DSCR loans flip the qualification question: instead of "can the borrower afford this payment?" the question becomes "does this property generate enough income to cover this payment?" The property qualifies, not the person.
This makes DSCR loans the primary tool for investors scaling a rental portfolio beyond the 1-2 properties where conventional financing still works cleanly.
For occupied properties: The actual current lease amount, verified by the executed lease agreement.
For vacant properties at acquisition: Most lenders use a market rent analysis from the appraiser — a rent schedule showing comparable rental rates for similar properties in the market. Some lenders use a percentage of the appraiser's rent estimate (e.g., 90%) to build in a vacancy assumption.
For short-term rentals (Airbnb/VRBO): More complex. Some lenders use historical actual income from platforms; others use a blended market rent estimate. STR programs are specialized and not all DSCR lenders offer them.
These are different ratios used in different contexts:
DSCR loans use DSCR. Conventional loans use DTI. The distinction is why DSCR loans are accessible to investors who would fail conventional DTI qualification.
Lenders typically offer better terms — lower rates, higher LTV — to properties with stronger DSCR. A property at 1.40 DSCR may get a lower rate than the same property at 1.05 DSCR, because the higher cash flow ratio means lower default risk.
