DSCR (Debt Service Coverage Ratio) = Net Operating Income divided by Annual Debt Service. It measures how well a property's income covers its mortgage payments. A DSCR above 1.25 is typically required for investment property loans.

What DSCR do lenders require?

Most residential investment property lenders require a minimum DSCR of 1.20 to 1.25. Commercial lenders often require 1.25 to 1.35. A DSCR below 1.0 means the property doesn't generate enough income to cover its mortgage payments.

What is NOI in real estate?

Net Operating Income (NOI) = Gross Rental Income × (1 - Vacancy Rate) - All Operating Expenses. Operating expenses include property taxes, insurance, management fees, maintenance, CapEx reserves, and utilities. NOI excludes mortgage payments.

Enter Loan Details

Provide your current loan balance, interest rate, and remaining term. The calculator computes annual debt service (P&I payments).

Check Your DSCR

A DSCR above 1.25 means lenders can comfortably qualify you. Use the Stress Test tab to see how your DSCR holds up under adverse scenarios.

Key Terms

DSCR

Debt Service Coverage Ratio. NOI divided by annual debt service. Measures how many times the property's income covers its mortgage payments.

NOI

Net Operating Income. Effective gross income minus all operating expenses. Does NOT include mortgage payments or income taxes.

Debt Service

Total annual principal and interest payments on the property loan. Does not include escrow (taxes/insurance paid separately).

EGI

Effective Gross Income. Gross Scheduled Income × (1 − Vacancy Rate). The income you actually collect after accounting for vacancies.

Cap Rate

Capitalization Rate = NOI / Property Value. Measures the unlevered return on investment, independent of financing.

Break-Even Occupancy

The minimum occupancy rate required so that income covers all expenses plus debt service. Below this rate, the property generates negative cash flow.

CapEx Reserve

Capital Expenditure reserve — savings set aside for major future repairs (roof, HVAC, appliances). Typically 5–10% of EGI.

50% Rule

A quick underwriting heuristic: total operating expenses (excluding debt service) typically equal about 50% of gross rents.

Understanding DSCR for Investment Properties

The Debt Service Coverage Ratio (DSCR) is the single most important metric when underwriting an investment property for financing. Lenders use DSCR to determine whether the property can support the proposed debt load — not whether the borrower can. This is what makes DSCR loans fundamentally different from conventional mortgages, which focus primarily on the borrower's personal income.

How Lenders Use DSCR

Most residential investment property lenders require a minimum DSCR of 1.20 to 1.25. This means the property's Net Operating Income must be 20–25% greater than its annual mortgage payments. A DSCR of exactly 1.0 means the property breaks even — all rental income goes to the mortgage with nothing left over. A DSCR below 1.0 means the property generates negative cash flow relative to debt service, and most lenders will not approve the loan.

Calculating NOI Accurately

The most common mistake in DSCR analysis is understating operating expenses. Investors often include only property taxes and insurance, forgetting that a realistic NOI calculation must include property management fees (8–12% of EGI), maintenance and repairs (5–10%), capital expenditure reserves (5–10%), and vacancy losses (typically 5–8% for stabilized properties). Including all these expenses is what distinguishes institutional-quality underwriting from back-of-the-envelope estimates.

The 50% Rule as a Sanity Check

A useful rule of thumb: total operating expenses (excluding debt service) typically run about 50% of gross rents for single-family and small multifamily properties. This is called the "50% rule." If your expenses are coming in well below 50%, double-check that you've included all line items — especially CapEx reserves, which inexperienced investors often omit.

DSCR Loans vs Conventional Investment Property Loans

Traditional investment property financing requires the borrower to qualify based on personal income, typically showing 1–2 years of tax returns. DSCR loans qualify based entirely on the property's income — making them ideal for self-employed borrowers, investors with many properties who have "used up" their conventional debt-to-income ratios, or investors who need to close quickly without income documentation. DSCR loan rates are typically 0.5–1.0% higher than conventional rates.

Frequently Asked Questions

What DSCR do most lenders require?

Most residential investment property lenders require a minimum DSCR of 1.20 to 1.25. Commercial lenders, especially for apartment buildings, often require 1.25 to 1.35. Some aggressive lenders may approve at 1.15, but rates will be higher.

What does a DSCR of 1.25 mean?

A DSCR of 1.25 means the property generates 25% more income than required to make its mortgage payments. For every dollar owed in debt service, the property earns $1.25 in NOI.

Can a property have a DSCR below 1.0?

Yes, though most lenders won't finance such properties. A DSCR below 1.0 means the property's income doesn't cover its debt service — the investor must cover the shortfall from personal income. This is "negative cash flow" investing, sometimes acceptable if appreciation potential is high.

How is NOI different from cash flow?

NOI = EGI − Operating Expenses (before debt service). Cash Flow = NOI − Debt Service (and sometimes other expenses). NOI is a property-level metric used for valuation and DSCR. Cash flow is the investor's actual profit after paying the mortgage.

Should I include CapEx in my DSCR calculation?

Yes. While some lenders calculate NOI without CapEx reserves (to get a more favorable DSCR), savvy investors always include CapEx to accurately represent the true cost of ownership. A property that looks great on paper but needs $30k in repairs in year 3 is not as profitable as it appeared.

What is the maximum LTV for a DSCR loan?

Most DSCR lenders cap LTV at 75–80% for single-family rental properties. Some allow 80% with mortgage insurance or higher rates. LTV is also limited by appraised value, so if the appraised value comes in lower than the purchase price, your loan amount may be reduced.

How do I improve my DSCR?

You can improve DSCR by: increasing rental income (upgrade the property, adjust to market rents), reducing operating expenses, making a larger down payment (reducing loan amount and debt service), or extending the loan term to reduce monthly payments. Reducing the interest rate via points or shopping lenders also helps.

Does DSCR include property taxes and insurance?

Yes — property taxes and insurance are operating expenses that reduce NOI in the DSCR calculation. However, the "debt service" in DSCR refers only to principal and interest (P&I), not PITI (Principal, Interest, Taxes, Insurance). Some lenders calculate DSCR using PITIA (adding Association fees), so clarify with your lender.

What is a DSCR loan?

A DSCR loan is a type of investment property financing that qualifies based on the property's rental income rather than the borrower's personal income. Ideal for self-employed investors, those with many properties, or anyone who wants to keep their personal and investment finances separate. No tax returns required.

What is break-even occupancy?

Break-even occupancy is the minimum occupancy rate at which total revenue equals total expenses (including debt service). Below this occupancy, the property loses money. Calculated as: (Operating Expenses + Annual Debt Service) ÷ Gross Scheduled Income.

How does interest rate affect DSCR?

Higher interest rates directly reduce DSCR by increasing debt service. For example, on a $300k loan over 30 years, a 1% rate increase raises monthly payments by roughly $170, reducing annual NOI available for DSCR by $2,040. This is why rising interest rates can quickly push properties below the 1.25 DSCR threshold.

What is the 50% rule for rental properties?

The 50% rule states that approximately 50% of gross rental income will go toward operating expenses (excluding mortgage payments). It's a rough approximation for quick underwriting — actual expenses vary based on property age, location, and management style. A newer, well-maintained property might have 40% expenses; an older building with deferred maintenance might hit 60%.

Can DSCR be calculated for short-term rentals (Airbnb)?

Yes, though lenders typically use an estimated "market rent" from a market analysis (like AirDNA data) rather than actual STR income, which is volatile. Some DSCR lenders now specialize in STR properties and will use trailing 12-month average income.

How do DSCR loans differ from hard money loans?

DSCR loans are long-term financing (15–30 year terms) based on property income. Hard money loans are short-term (6–24 months), asset-based bridge financing used for acquisitions and rehabs, typically at much higher rates (10–15%). After a rehab, investors often refinance hard money into a DSCR loan once the property is stabilized and generating rents.

What's the difference between DSCR and cap rate?

Cap rate = NOI / Property Value — it's a leverage-free return metric used for property valuation. DSCR = NOI / Debt Service — it's a financing metric measuring how well income covers loan payments. A property can have a great cap rate but poor DSCR if it's heavily leveraged with high-rate debt.
