How to use this calculator
- Enter the monthly rent. Lenders typically use the lower of the lease and the appraiser’s market rent.
- Enter yearly property taxes and insurance, and monthly HOA dues if any.
- Enter the loan amount, rate and term. Tick interest-only if the offer has an interest-only period — many DSCR lenders calculate the ratio on the interest-only payment in that case.
- Choose the lender’s minimum DSCR to see your maximum loan and the rent needed to qualify.
- Optionally add vacancy and operating expenses for the investor-style NOI ratio.
What is DSCR?
The debt service coverage ratio measures how comfortably a property’s income covers its loan payment. For residential DSCR loans, it’s simple:
DSCR = gross monthly rent ÷ PITIA
PITIA = principal + interest + property taxes/12 + insurance/12 + HOA dues
A DSCR of 1.0 is break-even; below 1.0 the rent doesn’t cover the payment. Commercial and multifamily lenders instead use net operating income (NOI) ÷ annual debt service, which subtracts vacancy and operating expenses first and therefore produces a lower number for the same property.
Typical DSCR loan requirements
| Factor | Typical range |
|---|---|
| Minimum DSCR | 1.0–1.25 (some programs below 1.0) |
| Down payment | 20%–25% (lower LTV for sub-1.0 DSCR) |
| Credit score | About 620–680 minimum; best pricing at 720+ |
| Cash reserves | Commonly 3–12 months of PITIA |
| Rates | Usually higher than conventional investor loans |
| Prepayment penalty | Common, e.g. 5-4-3-2-1 step-down or 3 years |
| Borrower | Individual or LLC; no personal income verification |
Terms vary widely between lenders — treat these as benchmarks and compare offers.
Worked example
A single-family rental earns $2,800 a month. Taxes are $4,200 a year, insurance $1,800, no HOA. The investor wants a $280,000 30-year loan at 7.25%.
- Principal and interest: $1,910.09; taxes and insurance add $500 → PITIA $2,410.09.
- DSCR = $2,800 ÷ $2,410.09 = 1.16 — qualifies at a 1.0 minimum but not at 1.25.
- To reach 1.25, the loan could be at most about $255,000 (a larger down payment), or rent would need to be about $3,013.
- On an NOI basis (5% vacancy, $3,000 of other expenses), the ratio is about 1.00 — the property roughly breaks even after all costs.
How to improve your DSCR
- Put more down. A smaller loan lowers principal and interest directly.
- Buy down the rate with discount points, or compare more lenders.
- Choose an interest-only period if the lender calculates DSCR on the interest-only payment.
- Support a higher rent with comparable rentals, renovations or furnishing (for mid-term rentals).
- Shop insurance and appeal the tax assessment — both flow straight into PITIA.
- Choose a longer amortization (such as a 40-year option) if offered.
DSCR loan pros and cons
| Pros | Cons |
|---|---|
| No tax returns, W-2s or personal DTI | Higher rates and fees than conventional loans |
| Can close in an LLC | Larger down payments |
| No cap on the number of financed properties at many lenders | Prepayment penalties are common |
| Fast closings for experienced investors | Only for investment properties, not your home |
Frequently asked questions
How do lenders calculate DSCR for a rental property?
Most residential DSCR lenders divide the property’s gross monthly rent by its monthly PITIA — principal, interest, property taxes, insurance and any HOA dues. A ratio of 1.0 means the rent exactly covers the payment; 1.25 means rent is 25% higher than the payment.
What is a good DSCR?
1.25 or higher is considered strong and typically earns the best rates and highest loan-to-value. Many lenders accept 1.0 to 1.24, sometimes with a slightly higher rate. Some “no-ratio” or sub-1.0 programs exist for strong borrowers, usually with a larger down payment.
What rent do lenders use?
Usually the lower of the signed lease and the appraiser’s market-rent estimate (for 1–4 unit homes, the rent schedule attached to the appraisal). For short-term rentals, some lenders accept 12 months of booking history or an AirDNA-style projection with a haircut.
Is a DSCR loan the same as a commercial loan?
No. DSCR loans for 1–4 unit rentals are residential non-QM mortgages. Commercial lenders use a different DSCR — net operating income (after vacancy and operating expenses) ÷ annual debt service. The calculator shows both.
Do DSCR loans require tax returns or pay stubs?
Generally no — that’s their main appeal. Qualification is based on the property’s income, your credit score, down payment and cash reserves. That makes them popular with self-employed investors and people with many properties.
