DSCR — the debt service coverage ratio — is a property's net operating income divided by its annual debt service. It's the lender's first test of whether a property's cash flow covers its loan payments: a DSCR of 1.25x means the property earns 25% more each year than it owes the lender.
Why DSCR Matters in CRE
Lenders approve and size loans around minimum DSCRs because the ratio measures cushion. At 1.25x, net operating income can fall roughly 20% before the property stops covering its payments; at 1.05x, one soft quarter can do it. Multifamily lenders typically require around 1.20–1.25x, while office, retail, and hospitality usually carry higher minimums because their income is less stable.
Below 1.0x, the property no longer pays for its own debt — the owner feeds the loan out of pocket, and the deal drifts toward default or a workout. A close cousin, debt yield, is NOI divided by the loan amount: the same cushion idea, but immune to rate and amortization assumptions.
A Worked Example
A stabilized multifamily deal comes in with these numbers:
- Net operating income (T-12): $1,149,700
- Annual debt service: $890,000
- DSCR: $1,149,700 ÷ $890,000 = 1.29x
- Lender minimum: 1.25x — the deal clears with room
Now move rates. If the loan reprices so annual debt service climbs to $985,000, DSCR falls to 1.17x — below the 1.25x minimum, even though the property's performance never changed. In practice the lender shrinks the loan instead: at 1.25x coverage, this NOI supports about $920,000 of annual debt service, and proceeds get sized down until the payment fits under that ceiling. That's why most teams test DSCR across rate scenarios rather than at a single quote.
How Lenders Build the Inputs
Both inputs are less obvious than they look. NOI is usually the trailing twelve months with lender adjustments — a vacancy floor, a management fee even on self-managed assets, replacement reserves. Debt service often isn't your actual payment either: many lenders underwrite an amortizing payment on interest-only loans, or test the rate with a cushion added. The same deal can clear one lender's test and miss another's.
How Teams Handle DSCR Today
Mostly in each deal's spreadsheet, one rate scenario at a time — and the table gets rebuilt whenever the quote changes. With Playgrounds, you describe the model once and get an underwriting app that holds DSCR live against your loan terms, recalculating across rate scenarios as new statements and quotes come in.
Frequently Asked Questions
What is a good DSCR?
It depends on the asset and the lender. Multifamily lenders typically want at least 1.20–1.25x, while office, retail, and hospitality often require 1.30x or higher because their income is less predictable. More cushion means more room for NOI to slip before the loan is at risk.
What happens if DSCR falls below 1.0x?
The property no longer generates enough income to cover its debt payments, so the owner covers the shortfall out of pocket. Sustained coverage below 1.0x typically leads to default, a workout, or a forced sale — the outcomes minimum DSCR requirements are designed to prevent.
Do lenders use my actual loan payment to calculate DSCR?
Not always. Many underwrite an amortizing payment even on an interest-only loan, apply a stressed interest rate, or adjust NOI with vacancy floors and reserves. Ask each lender how they build the ratio — the same deal can produce different DSCRs at different shops.
What's the difference between DSCR and debt yield?
DSCR compares NOI to the annual loan payment, so it moves with interest rates and amortization. Debt yield is NOI divided by the loan amount, ignoring loan terms entirely. Lenders track both because low rates can flatter DSCR while debt yield stays put.
