This page explains the specific DSCR ratio requirements lenders look for, how to calculate your ratio, and what happens if your ratio is too low.
What DSCR Ratio Do You Need To Qualify?
Most DSCR lenders require a minimum DSCR ratio of 1.25 for approval with the best terms. Some may accept a ratio as low as 1.00 when you meet additional conditions like a higher down payment or stronger credit.

Key Terms for DSCR Ratio Requirements
This section defines essential terminology used throughout this article to help you understand DSCR loan requirements and qualification criteria.
DSCR (Debt Service Coverage Ratio)
DSCR Definition A financial metric that measures a property's ability to cover its mortgage payment with rental income. Calculated as Net Operating Income ÷ Monthly Mortgage Payment. A DSCR of 1.25 means the property generates 25% more income than needed to cover the mortgage payment.
Net Operating Income (NOI)
NOI Definition Total rental income minus all operating expenses (taxes, insurance, maintenance, HOA fees, etc.) before mortgage payments. This is the income available to cover the mortgage payment and is used in DSCR calculations.
Portfolio DSCR
Portfolio DSCR Definition The overall DSCR ratio calculated across all properties in an investor's portfolio, used to assess portfolio-wide financial health. Lenders may require higher portfolio DSCR ratios for investors with multiple properties.
Individual Property DSCR
Individual Property DSCR Definition The DSCR ratio calculated for a single property, used to evaluate that specific property's income-generating ability. Each property in a portfolio must meet minimum DSCR requirements independently.
DSCR Loan Success Story
How Lenders Calculate DSCR Ratio (One Property)
Lenders use a simple formula to determine if your property generates enough income to qualify for a DSCR (Debt Service Coverage Ratio) loan:
→ DSCR = Net Operating Income ÷ Monthly Mortgage Payment
In plain English: the DSCR math formula shows whether a property makes enough money to pay the mortgage and have room to spare. A higher DSCR reassures lenders that the investment property is less risky and more likely to stay current on payments, even if property expenses or vacancies fluctuate.
The key is showing lenders that your property generates at least 25% more income than required to cover the mortgage payment.
How Lenders Calculate Portfolio DSCR (Multiple Properties)
Lenders use two different calculation methods when you own multiple rental properties:
→ Individual Property DSCR = Property's Net Operating Income ÷ Property's Monthly Mortgage Payment
→ Portfolio-Wide DSCR = Total Net Operating Income from All Properties ÷ Total Monthly Mortgage Payments
In plain English: lenders evaluate each property individually, and your entire portfolio as a whole. Each property must meet minimum DSCR requirements, while your overall portfolio must demonstrate sufficient income to cover all mortgage payments with a safety margin.
The key is demonstrating that each property can support its own mortgage payment, while your entire portfolio generates sufficient income to cover all obligations with a safety margin.

What If Your DSCR Ratio Is Too Low For A Mortgage?
If your DSCR ratio is lower than what your lender requires, you're not alone. Many investors face this exact situation. The good news is that a low DSCR ratio doesn't mean you can't get financing — it just means you need to look at different options or adjust your approach.
DSCR Between 1.00 and 1.24
If your DSCR ratio falls between 1.00 and 1.24, some lenders may still consider your application. You may still qualify for a DSCR loan if you can:
- Make a larger down payment
- Maintain additional months of reserves
- Have a credit score above 700
- Show prior landlord experience
DSCR Below 1.00
If your DSCR ratio is below 1.00, most lenders will not approve your loan application because the property's income fails to cover its mortgage payment. It's unlikely you'll qualify for a DSCR loan unless you can:
- Improve your rental income
- Increase your down payment
- Choose a different property or loan structure
- Work with a specialized DSCR lender
Understanding why your ratio is low can help you figure out the best path forward. Common challenges include:
- Rental income estimates that don't match current market rates
- Operating expenses that are higher than expected
- Property prices that have outpaced rental growth in the area
- Down payment amounts that don't align with lender requirements
- Market changes that affect what properties can realistically rent for
These are normal challenges in real estate investing. The key is finding the right approach for your specific situation.

Next Step: Find Another Lender
If a lender turned you down for a DSCR loan, it may mean the lender's rules are the problem — not you. Many banks add extra requirements or don't offer every program, even when the property makes sense. DSCR loans are designed for situations like this, focusing on the property's income potential rather than your personal finances.
Different lenders have different requirements and programs available, so being denied by one lender doesn't necessarily mean you won't qualify elsewhere. Some lenders specialize in specific property types or investor profiles, while others have more flexible guidelines.
Before giving up, consider these practical steps:
- Check if your property's rental income is realistic for the area
- Verify your operating expenses are accurate and complete
- Look at properties in different price ranges that might have better DSCR ratios
- Consider if you can increase your down payment to improve the ratio
- Research lenders who specialize in your specific situation
The key is understanding that DSCR loans work differently than traditional mortgages. They're based on the property's ability to generate income, not your personal financial situation. This makes them accessible to investors who might not qualify for conventional loans.
