DSCR Explained

If you’re refinancing a commercial property, you’ll hear lenders mention DSCR — the debt service coverage ratio. It’s one of the most important metrics underwriters use to decide whether to approve your loan. Simply put, DSCR measures whether your property generates enough income to cover its debt payments. A strong DSCR (typically 1.25 or higher) signals to lenders that your property is a safe bet. A weak ratio can tank your application or force you into expensive terms. Understanding DSCR is essential for any commercial property owner looking to refinance, purchase, or improve their financing position.

DSCR Explained – The Plain-English Definition

DSCR is the ratio of your property’s annual net operating income (NOI) to its annual debt service (loan payments). In plain English: does your building make enough money to pay its mortgage — with room to spare?

Example: You own a $1 million retail property. After expenses (taxes, insurance, management, maintenance), the building generates $120,000 per year in net operating income. Your annual mortgage payments total $100,000. Your DSCR is:

DSCR = $120,000 / $100,000 = 1.20

This means your property earns 1.20 times its annual debt obligation. Lenders see this as a 20% cushion. If rental income dips or expenses spike, you can still make your payments without digging into reserves or personal funds.

How to Calculate DSCR Explained

The formula is:

DSCR = Net Operating Income (NOI) / Annual Debt Service

Step-by-step:

1. Calculate NOI: Take your property’s gross rental income, subtract operating expenses (property taxes, insurance, utilities, repairs, property management fees). Do NOT subtract mortgage payments or depreciation — those are financing and accounting items, not operating costs.

1. Calculate Annual Debt Service: Add up all your annual loan payments (principal + interest). If you’re evaluating a refinance, use the proposed new loan’s payments, not your current debt.

1. Divide: NOI ÷ Annual Debt Service = DSCR.

Worked example:

• Gross rental income: $200,000/year
• Operating expenses: $70,000/year
• NOI: $200,000 – $70,000 = $130,000
• Proposed loan payments: $110,000/year
• DSCR: $130,000 / $110,000 = 1.18

What Lenders Want to See

Most commercial lenders require a minimum DSCR of 1.20 to 1.30, though standards vary by property type and loan program:

• Multifamily (5+ units): Minimum 1.20–1.25
• Office/Retail: Minimum 1.25–1.30
• Industrial/Warehouse: Minimum 1.25
• Hotel/Hospitality: Minimum 1.30–1.40 (higher volatility)
• Special-purpose (gas station, church, etc.): Minimum 1.35–1.50

Why the cushion? Lenders build in a buffer to protect against:

• Vacancy risk
• Rent roll turnover
• Rising expenses (insurance, taxes)
• Economic downturns

A DSCR below 1.20 typically triggers:

• Loan denial
• Higher interest rates (risk premium)
• Larger down payment requirements
• Personal guarantee or additional collateral

A DSCR above 1.40 often qualifies you for better rates and terms — lenders compete for low-risk borrowers.

Improving Your DSCR Explained

If your DSCR falls short, you have options:

1. Increase NOI:

• Raise rents (where market allows)
• Reduce vacancy (better marketing, tenant retention)
• Cut operating costs (renegotiate contracts, improve efficiency)
• Add revenue streams (parking fees, laundry, storage)

1. Reduce Debt Service:

• Refinance to a longer amortization (30 years vs. 25) — lowers monthly payments
• Negotiate a lower interest rate (shop lenders via a broker)
• Pay down principal before refinancing (smaller loan = smaller payment)
• Consider interest-only financing (short-term fix, but monthly cost drops)

1. Adjust the Loan Amount:

• Make a larger down payment (borrow less)
• If refinancing, pull out less cash

Best approach: Tackle both sides. Even a 5% rent increase plus a 0.5% rate reduction can push a 1.15 DSCR above 1.25 and unlock approval.

FAQ Section

What is a good DSCR? A DSCR of 1.25 or higher is considered good for most commercial property types. Lenders view anything above 1.20 as acceptable, while 1.30+ signals strong cash flow and lower risk. Requirements vary by property type — multifamily may accept 1.20, while hotels often require 1.35–1.40 due to income volatility.

How is DSCR calculated? DSCR = Net Operating Income (NOI) ÷ Annual Debt Service. NOI is your property’s gross income minus operating expenses (excluding mortgage payments). Annual Debt Service is your total yearly loan payments (principal + interest). Use the calculator above or our dedicated DSCR calculator to run your numbers.

What if my DSCR is below 1.0? A DSCR below 1.0 means your property doesn’t generate enough income to cover its debt payments — you’re losing money every month. Most lenders won’t finance a property with DSCR under 1.0. You’ll need to either increase income, reduce expenses, pay down debt, or bring in more equity to improve the ratio before qualifying for financing.

Do all commercial loans use DSCR? Most income-producing commercial properties are underwritten based on DSCR. However, DSCR loans (also called “no-doc” or “investor cash flow” loans) are a specific loan product that qualifies borrowers solely on the property’s DSCR, without verifying personal income or tax returns. Standard commercial loans consider both DSCR and borrower financials.

How does DSCR affect my interest rate? Higher DSCR typically earns you a lower interest rate. A property with 1.40+ DSCR is less risky for the lender, so you may qualify for rates 0.25%–0.50% lower than a property at 1.20. Conversely, borderline DSCR (1.15–1.20) often triggers rate premiums or requires personal guarantees.
