DSCR: The Lender's "Go/No-Go" Metric

The **Debt Service Coverage Ratio (DSCR)** is the single most important number to a commercial lender. It tells them if your property generates enough "cushion" to survive a spike in vacancy or expenses while still paying its mortgage.

The Magic "1.25x" Number

Why do lenders insist on 1.25x? It's not arbitrary. A 1.25x DSCR means you have a 25% margin of safety. If your rents drop by 10% or your taxes jump by 10%, you can still write the mortgage check. If your ratio is 1.0x, you have zero room for error.

How to Improve Your DSCR

If your DSCR is coming in too low (e.g., 1.10x), you have three levers:

  1. Reduce the Loan: Putting more cash down lowers the debt service.
  2. Lower the Rate: Shop for a lower interest rate to reduce the monthly check.
  3. Increase NOI: Drive up rents or cut waste before going to market.

Expert FAQ

What happens if my DSCR drops below 1.0x?

A DSCR below 1.0x means the property's income is insufficient to cover its debt payments. This is a "cash-flow negative" situation and often constitutes a technical default, potentially triggering a cash sweep or foreclosure if not corrected.

Why do lenders require a 1.25x DSCR margin?

The "cushion" (0.25x) protects the lender against market volatility. If revenue drops by 10% or expenses spike, a 1.25x ratio ensures there is still enough net income to pay the mortgage without the borrower needing to go out-of-pocket.

How does an "Interest Only" period affect DSCR?

It artificially inflates it. Since you aren't paying principal, your total debt service is lower, resulting in a higher DSCR. Lenders will usually underwrite the loan based on the full "Amortizing DSCR" to ensure long-term viability.

Is DSCR calculated on Gross or Net income?

It is strictly calculated on Net Operating Income (NOI). You must subtract all operating expenses (taxes, insurance, maintenance, management) from your gross rents before dividing by the annual debt service.

Can I include "Other Income" like parking or laundry in DSCR?

Generally, yes. Most lenders will count any recurring, verifiable income stream produced by the property. However, they may apply a higher vacancy factor to "other income" compared to base rent.
