What is DSCR?
The debt service coverage ratio (DSCR) measures whether a rental property's income covers its loan payments. A DSCR of 1.0 means the income exactly covers the payment. Above 1.0, there's money left over. Below 1.0, you're paying the difference out of pocket each month.
DSCR matters most if you're financing with a DSCR loan. These investor mortgages qualify you based on the property's rent instead of your personal income, so the ratio is what decides whether you're approved and at what rate.
How to calculate DSCR
There are two common versions, and this calculator shows both.
1. The lender method: rent ÷ PITIA
PITIA is principal, interest, property taxes, insurance and HOA or association dues. Most residential DSCR lenders use this version. It's simple and uses gross rent, with no deduction for vacancy, repairs or management.
2. The NOI method: NOI ÷ debt service
Net operating income (NOI) is rent minus vacancy and all operating costs: taxes, insurance, HOA, maintenance, utilities and management. Commercial lenders and experienced investors use this version. It's stricter, and it tells you more about whether the property really pays for itself.
What DSCR do lenders require?
| DSCR | What it usually means |
|---|---|
| 1.25+ | Strong. Typically qualifies for the best DSCR loan rates and terms. |
| 1.0 – 1.24 | Meets the minimum at most DSCR lenders, often with a somewhat higher rate. |
| 0.75 – 0.99 | Some specialty programs allow it, usually with a bigger down payment, more reserves and a higher rate. |
| Below 0.75 | Hard to finance with a DSCR loan. The rent falls well short of the payment. |
Requirements vary by lender and also depend on your credit score, down payment and cash reserves, so treat these as typical ranges, not guarantees.
Worked example
A duplex bought for $350,000 with 25% down, at 7.25% over 30 years:
- Loan of $262,500 → principal and interest of about $1,791/month
- Taxes $400/month + insurance $150/month → PITIA of about $2,341/month
- Rent of $3,000/month
Lender DSCR: $3,000 ÷ $2,341 = 1.28. That clears the 1.25 mark for better loan terms.
NOI DSCR: after 5% vacancy and $4,200/year of other costs, NOI is $23,400 against about $21,490 of yearly loan payments: 1.09. The property covers its debt, but with only about $160 a month left over once real-world costs are included.
That gap is common, and it's the reason to check both numbers. A deal can qualify for financing and still leave you with very little cash flow.
How to improve your DSCR
- Put more down. A smaller loan lowers the monthly payment.
- Negotiate the price. Same effect as a bigger down payment, without the extra cash.
- Raise rents to market, or add income like laundry, parking or storage.
- Shop the rate. Even a half-point lower rate meaningfully improves the ratio.
- Lower insurance or appeal the tax assessment, since both count in PITIA.
Frequently asked questions
What is a good DSCR for a rental property?
Most DSCR lenders want at least 1.0, meaning the rent fully covers the payment including taxes, insurance and HOA. A DSCR of 1.25 or higher usually gets the best rates and terms.
Does a DSCR loan look at my personal income?
Generally no. DSCR loans qualify you on the property's rental income, which is why they're popular with self-employed investors and people who own several rentals. Lenders still check your credit score, down payment and cash reserves.
Which rent do lenders use?
Usually the lower of the current lease amount or the market rent estimated by the appraiser. For a vacant property, it's typically the appraiser's market rent figure.
Can I get a DSCR loan with a ratio below 1.0?
Some specialty lenders go as low as about 0.75, but expect a larger down payment, more reserves and a higher rate. Below 1.0 the rent doesn't fully cover the payment, so you'd be covering the shortfall each month.
Check the whole deal, not just one ratio
DSCR tells you whether you can finance a property. It doesn't tell you whether it's a good investment. ElmCheck's free deal analyzer runs the full picture for 1–7 unit rentals: cash flow, cash-on-cash return, cap rate, IRR, tax effects and a buy, maybe or pass verdict.
