DSCR Loan Calculator For Real Estate Investors
DSCR Loan Calculator

How To Use This Calculator
Enter four things:
- Monthly rental income — the actual or projected rent the property generates
- Loan amount — what you plan to borrow (not the purchase price)
- Interest rate — use current DSCR rates or the rate you’ve been quoted
- Monthly expenses — property taxes, insurance, and HOA if applicable
The calculator divides your monthly rent by your total monthly debt service (PITIA) to produce your DSCR ratio. The result tells you whether your property qualifies — and at what tier.
What Is DSCR and How Is It Calculated?
DSCR stands for Debt Service Coverage Ratio. It’s the single number lenders use to determine whether a rental property’s income is sufficient to cover its debt obligations.
The DSCR formula used by most mortgage lenders is:
DSCR = Monthly Rental Income ÷ Monthly Debt Service (PITIA)
Where PITIA = Principal + Interest + Taxes + Insurance + HOA (if applicable).
Example:
- Monthly rent: $2,800
- Monthly P&I: $2,100
- Monthly taxes: $350
- Monthly insurance: $150
- HOA: $0
- Total PITIA: $2,600
- DSCR: $2,800 ÷ $2,600 = 1.08
A DSCR of 1.08 means the property generates 8% more income than it costs to carry. It qualifies at standard DSCR terms.
What Your DSCR Score Means
| DSCR | Status | What It Means |
|---|---|---|
| 1.25 or higher | Strong | Best rates. Qualifies at most DSCR lenders. |
| 1.00–1.24 | Qualifies | Property covers debt service. Standard DSCR programs available. |
| 0.75–0.99 | Qualifies at Defy | Most lenders decline this. Defy lends down to 0.75. |
| Below 0.75 | Does Not Qualify | Consider a larger down payment or higher-income property. |
Most DSCR lenders require a minimum ratio of 1.00. Defy Mortgage lends down to 0.75 — which means investors in high-appreciation markets, short-term rental operators, and value-add buyers can qualify on deals that other lenders reject outright.
Typical DSCR Loan Requirements
| Requirement | Typical Range |
|---|---|
| Minimum DSCR | 0.75 – 1.00 |
| Credit score | 640+ |
| Max LTV | Up to 85% |
| Loan term | 30-year fixed |
| Property types | SFR, condo, 2–4 unit |
Defy Mortgage offers DSCR loans down to 0.75 DSCR, up to 85% LTV, and accepts credit scores starting at 640.
Tips to Improve Your DSCR Before You Apply
If your DSCR came in lower than you’d like, here are the most effective levers:
Increase your down payment. A larger down payment reduces your loan amount, which reduces your monthly P&I, which improves your DSCR. Going from 80% to 75% LTV can meaningfully change the ratio.
Choose interest-only. An interest-only structure reduces your monthly payment, which improves your DSCR. Defy offers interest-only options on DSCR loans at approximately 0.25% over the standard amortizing rate. For cash-flow-focused investors, the math often works in their favor.
Verify market rents. If the property is vacant or below market, use a rental market analysis to show the lender what the property should rent for. Most DSCR lenders will underwrite to market rent, not just in-place rent.
Consider the property type. SFR properties qualify at the best terms. If you’re looking at a 2–4 unit, condotel, or short-term rental, the underwriting parameters shift slightly.
Investors who want to see how DSCR affects loan pricing can also review current DSCR loan rates.

DSCR Loan Calculator FAQs
What is a good DSCR ratio for an investment property?
A DSCR of 1.25 or higher is considered strong and qualifies for the best rates at most lenders. A ratio of 1.00–1.24 qualifies at standard terms. Defy Mortgage also offers programs for properties with a DSCR as low as 0.75, which covers many deals that other lenders decline.
Does DSCR use gross rent or net rent?
DSCR calculations use gross monthly rent — the total rent the property generates before any expenses. Monthly debt service (PITIA) is calculated separately and includes principal, interest, taxes, insurance, and HOA. Operating expenses like maintenance, vacancy, and property management are not included in the standard DSCR calculation.
Can I use projected rent for a DSCR loan?
Yes. Most DSCR lenders, including Defy Mortgage, will underwrite to market rent on vacant or recently acquired properties. An appraisal or rental market analysis is typically used to document the projected rent.
What’s the minimum DSCR Defy Mortgage accepts?
Defy Mortgage accepts DSCR loans down to 0.75. Loans below 1.0 carry a rate premium relative to loans at 1.0 or better. Adequate reserves are required for sub-1.0 DSCR approvals.
How does DSCR differ from DTI?
DTI (Debt-to-Income) is used on conventional loans and measures your personal income against your total debt obligations. DSCR ignores your personal income entirely — it only looks at the property’s rental income versus the property’s debt service. This is why DSCR loans don’t require tax returns, W-2s, or employment verification.
Can I use a DSCR loan for a short-term rental (Airbnb/VRBO)?
Yes. Defy Mortgage finances short-term rental properties under DSCR programs. Rental income can be documented using historical Airbnb data, a rental market analysis, or an AirDNA report for new acquisitions.
How quickly can I get a DSCR rate quote from Defy Mortgage?
Most investors receive a rate indication within 5 minutes of connecting with a Defy mortgage consultant. Official rate locks happen once the loan is in process. Most DSCR loans close in 14–21 days.
