DSCR Loan Calculator

What Is DSCR and Why Does It Matter?

The Debt Service Coverage Ratio measures how much rental income a property generates relative to its total monthly debt obligations. A DSCR of 1.0 means income exactly covers expenses. A DSCR above 1.25 is considered strong by most lenders and opens up better rates and terms.

DSCR Loan Qualification — No Personal Income Needed

Unlike conventional investment loans, DSCR loans don’t verify your personal income, tax returns, or employment. The property qualifies based on its own cash flow. This makes DSCR loans ideal for self-employed investors, those with multiple properties, and anyone who prefers to keep business and personal finances separate.

Typical DSCR Loan Requirements

• Minimum DSCR: typically 1.0 (some lenders allow below 1.0 for strong borrowers)
• Minimum down payment: 20–25%
• Minimum credit score: typically 660+
• Property types: single family, 2–4 unit, condos, short-term rentals
• Loan amounts: typically $100K–$3M+

Ways to Improve Your DSCR Before You Apply

Because DSCR is calculated by dividing rental income by your total monthly property expenses, there are really only two ways to move the ratio: increase the income side or decrease the expense side. On the income side, reviewing comparable rents for similar properties in the area can confirm whether your estimated rent is realistic, and in some cases a lender will use an appraiser’s rent survey rather than your own estimate, which can work in your favor if the market rent is higher than you assumed.

On the expense side, a larger down payment reduces your loan amount and therefore your monthly principal and interest payment, which directly improves DSCR. Shopping for a lower interest rate has a similar effect, since even a modest rate reduction lowers the monthly payment that rental income needs to cover.

Property taxes and insurance also factor into the PITIA figure used in this calculation, so it is worth getting an accurate quote for insurance on investment properties, which is often priced differently than a primary residence policy, rather than relying on a rough estimate.

If a property’s DSCR comes in below what a lender requires, some borrowers choose to buy down the rate with points at closing to lower the monthly payment enough to qualify, while others adjust their offer price or down payment amount. Running a few different purchase price and down payment scenarios through this calculator before making an offer can help you understand what it would take to reach a stronger DSCR tier, such as 1.25, which often unlocks better pricing than a DSCR closer to 1.0.
