How the DSCR calculation works
DSCR (Debt Service Coverage Ratio) measures whether a property's rental income covers its full mortgage payment. The formula is straightforward:
The DSCR Formula
DSCR = Monthly Rent ÷ Monthly PITIA
Where PITIA = Principal + Interest + Taxes + Insurance + HOA
The ratio tells you (and the lender) whether the property pays for itself. A DSCR of 1.0 means the property breaks even — rental income exactly equals the mortgage payment. Above 1.0, the property generates cash flow. Below 1.0, the property loses money each month.
How to read your DSCR result
- 1.25 or higher: Strong cash flow. Qualifies for best DSCR loan programs.
- 1.00 to 1.24: Acceptable for many DSCR lenders. Some programs require 1.20+ minimum.
- Below 1.00: Property doesn't fully cover the loan payment. Limited lender options, often requires larger down payment.
- Below 0.75: Typically disqualifying for standard DSCR loans.
How transaction type affects your DSCR
DSCR lenders price the three main transaction types differently because they carry different risk profiles. The same property can produce three different DSCR results depending on whether you're buying it, refinancing it without taking cash out, or refinancing with cash-out.
Purchase loans
Purchase financing typically receives the best pricing in DSCR programs. The lender is funding the original acquisition, the property has fresh comparables (the purchase price itself), and the borrower has demonstrated commitment by completing closing on a new transaction. Most programs allow up to 80% LTV on purchases.
Rate/term refinance
Rate/term refinances replace your existing loan with new financing at different terms (different rate, term length, or both) without extracting cash. These typically price about 0.125% higher than purchase loans — the rate adjustment reflects the slightly different risk profile of refinancing an existing loan. Maximum LTV is similar to purchase.
Cash-out refinance
Cash-out refinances replace your existing loan with a larger one, with the difference paid to you in cash. These price meaningfully higher (typically 0.375% above purchase rates) because lenders view extracting equity as higher risk. Maximum LTV is also lower — typically 75% versus the 80% allowed on purchase. The combination of higher rate and lower LTV cap means cash-out scenarios often produce the weakest DSCR ratios for the same property.
Current DSCR loan program parameters
Most DSCR lenders share similar program structures, with some variation. Typical parameters:
| Parameter | Typical Range |
|---|---|
| Minimum DSCR | 1.0 to 1.25 (varies by lender) |
| Maximum LTV (purchase) | 75% to 80% |
| Maximum LTV (rate/term refi) | 75% to 80% |
| Maximum LTV (cash-out refi) | 70% to 75% |
| Minimum FICO | 620 to 680 (varies) |
| Cash reserves required | 3 to 12 months PITIA |
| Rate adjustment vs purchase: rate/term refi | ~+0.125% |
| Rate adjustment vs purchase: cash-out refi | ~+0.375% |
| Property types accepted | SFR, 2-4 unit, condos, sometimes STR |
How to improve your DSCR
If your current scenario doesn't qualify, several adjustments can move your DSCR into qualifying range:
- Increase your down payment (purchase) or reduce LTV (refi). Smaller loan = lower monthly payment = higher DSCR. Moving from 20% to 30% down typically improves DSCR by 0.10 to 0.20.
- Raise rents to market rate. If your property is rented below market, adjusting to market rents (with documentation) can significantly improve DSCR. Even $200/month additional rent can move DSCR by 0.10.
- Choose a longer loan term. A 30-year amortization produces lower monthly payments than a 25-year, improving DSCR. Some lenders offer 40-year terms or interest-only periods.
- Find lower property taxes. Properties in lower-tax jurisdictions naturally have better DSCR math.
- Wait for better rates. Even a 0.5% rate reduction can meaningfully improve DSCR on the same property.
- Consider a different transaction structure. If you're refinancing, a rate/term refi typically prices better than cash-out. If you don't need the cash, taking less cash out (or none) can move your scenario from cash-out pricing to rate/term pricing.
