What Is DSCR?
The debt service coverage ratio (DSCR) measures a property's ability to cover its mortgage payments from its operating income. It is calculated by dividing the property's net operating income (NOI) by its total annual debt service (mortgage principal plus interest payments). A DSCR of 1.25x means the property generates 25% more income than needed to make its loan payments. DSCR is the primary metric lenders use to determine whether a multifamily loan will be approved.
The formula is: DSCR = Net Operating Income / Annual Debt Service
How to Calculate DSCR
| Component | Example |
|---|---|
| Net Operating Income (NOI) | $350,000 |
| Annual Debt Service (P+I) | $275,000 |
| DSCR | 1.27x |
A DSCR of 1.27x means for every $1.00 of mortgage payment, the property generates $1.27 in net income. The $0.27 surplus provides a cushion against vacancy spikes, unexpected repairs, or income disruptions.
What DSCR Do Lenders Require?
| Loan Type | Typical Minimum DSCR |
|---|---|
| Freddie Mac Multifamily | 1.20x -- 1.25x |
| Fannie Mae DUS | 1.25x |
| CMBS Loans | 1.25x -- 1.30x |
| Bank/Portfolio Loans | 1.20x -- 1.35x |
| Bridge Loans | 1.00x -- 1.15x |
| HUD/FHA 223(f) | 1.176x (85% LTV) |
These minimums can vary based on market conditions, property quality, sponsor experience, and the overall risk profile of the deal. In tighter lending environments, required DSCRs trend higher.
Why DSCR Matters for Investors
DSCR determines the maximum loan amount you can obtain. If a property has $350,000 in NOI and the lender requires 1.25x DSCR, the maximum annual debt service is $280,000 ($350,000 / 1.25). At a 6% interest rate with 30-year amortization, this supports a maximum loan of approximately $4.67 million.
A higher NOI means a higher supportable loan, which means less equity required from investors. This is why increasing NOI through rent growth and expense reduction directly translates to increased leverage capacity.
How to Improve DSCR on a Deal
Increase revenue by raising rents to market, reducing vacancy, implementing RUBS utility billing, or adding income sources like pet rent and parking fees. Reduce expenses by negotiating property tax appeals, shopping insurance competitively, or implementing energy efficiency upgrades. On the financing side, longer amortization periods (30 years vs. 25 years) and lower interest rates both reduce annual debt service and improve DSCR.
