The debt service coverage ratio (DSCR) decides whether you qualify for a DSCR loan, how much you can borrow and what rate you pay. This guide explains what counts as a good DSCR, how lenders tier their pricing, and seven practical ways to raise your ratio, with the math for each.

How lenders calculate DSCR
For residential rental loans, most lenders use:
DSCR = monthly rent ÷ monthly PITIA
PITIA is the full monthly payment: principal, interest, property taxes, insurance and any association (HOA) dues.
Two details can change the answer:
- Which rent counts. Lenders often use the lower of your lease and the appraiser’s market-rent estimate (Fannie Mae’s Form 1007 for single-family homes). For a vacant property you’re buying, the market-rent estimate is usually all there is. Short-term rentals are often judged on a 12-month booking history or a third-party income estimate, sometimes with a discount.
- Which payment counts. If you choose an interest-only period, some lenders calculate DSCR on the interest-only payment and others on the full payment. Ask.
Commercial lenders often define DSCR differently, dividing net operating income by the annual debt payments. Check which definition a lender uses.
What is a good DSCR?
| DSCR | What it means | How lenders typically treat it |
|---|---|---|
| 1.25 or higher | Rent is at least 25% above the payment | Best pricing and the highest loan-to-value limits |
| 1.10–1.24 | A comfortable cushion | Standard pricing at many lenders |
| 1.00–1.09 | Rent just covers the payment | Accepted by many lenders, often at a higher rate or lower loan-to-value |
| 0.75–0.99 | Rent falls short of the payment | Only “no-ratio” or sub-1.0 programs, with lower loan-to-value, higher rates and more reserves |
| Below 0.75 | A large shortfall | Hard to finance with a DSCR loan |
Tiers vary by lender, so ask where each lender’s price breaks are. Moving from 1.19 to 1.20, or from 1.24 to 1.25, can change your rate.
A good target is 1.25 or higher. DSCR ignores vacancy, repairs, management and big replacements, so a property with a DSCR of exactly 1.00 usually loses money once those costs arrive. See rental property expenses investors underestimate.
A worked example
An investor wants to buy a rental that the appraiser says will rent for $2,400 a month:
- Loan: $260,000 at 7.5% over 30 years, so principal and interest are $1,818 a month
- Property taxes: $300 a month
- Insurance: $125 a month
- No HOA dues
PITIA is $2,243, so DSCR = $2,400 ÷ $2,243 = 1.07. That qualifies with many lenders but misses the better tiers. To reach 1.25, PITIA would have to fall to $1,920. At the same rate, that means a loan of about $213,800.
7 ways to raise your DSCR
Here’s how some of these changes affect the example:
| Change | New PITIA | New DSCR |
|---|---|---|
| Starting point | $2,243 | 1.07 |
| Borrow $30,000 less (bigger down payment) | $2,033 | 1.18 |
| Interest-only payment (if the lender uses it) | $2,050 | 1.17 |
| Buy the rate down to 6.75% with points | $2,111 | 1.14 |
| 40-year amortization | $2,136 | 1.12 |
| Support a rent of $2,600 | $2,243 | 1.16 |
- Make a larger down payment. It’s the most powerful lever, and a lower loan-to-value can also improve your rate.
- Choose an interest-only period, if the lender calculates DSCR on that payment. Remember that the payment rises when the interest-only period ends.
- Buy down the rate. Points cost cash up front. Divide their cost by the monthly saving to see how many months it takes to break even.
- Ask for a longer amortization. Some lenders offer 40-year terms, which lower the payment but increase total interest.
- Support a higher rent. A signed lease, strong comparable rentals, or improvements that justify a higher market rent can all help. At most lenders, the appraiser’s estimate still has the final word.
- Cut insurance and tax costs. Shop landlord insurance, consider a higher deductible, and appeal an inaccurate property tax assessment.
- Favor properties with lower fixed costs. HOA dues count in PITIA, so a property with high dues drags DSCR down.
Options 1 and 3 need cash, while options 2 and 4 increase the long-run cost. The right mix depends on your reserves and how long you plan to keep the property. Test combinations in our DSCR loan calculator.
DSCR is a floor, not a forecast
Lenders use DSCR because it’s simple. For your own decision, run the full numbers: vacancy, maintenance, capital expenses, management, cash flow and return. Our rental property calculator does all of this. If you plan to renovate and refinance, the BRRRR calculator shows how a refinance at the new value affects your DSCR and the cash you leave in the deal.
