What Is DSCR (Debt Service Coverage Ratio)?

The DSCR formula

DSCR is calculated as: Gross Monthly Rental Income ÷ PITIA (Principal, Interest, Taxes, Insurance, and Association dues if applicable). Lenders use either the actual lease amount for an occupied property or a market rent estimate from an appraisal (Form 1007) for a vacant or newly acquired property.

Because the ratio is built entirely from the property's numbers, a DSCR loan does not require personal income documentation, W-2s, or tax returns. This is why investors who are self-employed, own multiple properties, or write off income aggressively often find DSCR financing easier to qualify for than a conventional mortgage.

Worked examples: 1.0, 1.15, and 1.35 DSCR

Example A — DSCR of 1.0 (break-even): A property rents for $2,000/month. Its total PITIA payment is also $2,000/month. $2,000 ÷ $2,000 = 1.0. The property covers its own debt service with nothing left over for vacancy, repairs, or profit.

Example B — DSCR of 1.15 (income cushion): The same property rents for $2,300/month against a $2,000 PITIA payment. $2,300 ÷ $2,000 = 1.15. This 15% cushion provides room for vacancy or repairs; it is an illustration, not a separate Curlee qualifying tier. Curlee publishes a 1.0 minimum DSCR, with underwriting confirming the full file.

Example C — DSCR of 1.35 (strong cash flow): If rent is $2,700/month against the same $2,000 PITIA, DSCR is 1.35. Properties in this range typically qualify for the most favorable pricing and the highest leverage a lender offers, because the income cushion is substantial relative to the debt payment.

What counts inside PITIA

PITIA stands for Principal, Interest, Taxes, Insurance, and Association dues. Every one of these components affects the ratio, so two properties with identical rent and loan amount can have different DSCRs if their tax bill, insurance premium, or HOA dues differ.

• •Principal & Interest — the loan payment itself, driven by loan amount, rate, and amortization
• •Taxes — annual property tax bill divided by 12
• •Insurance — landlord/hazard insurance premium divided by 12
• •Association dues — HOA or condo fees, if applicable

How vacancy and insurance can move the ratio

DSCR is calculated on gross scheduled rent, not on rent actually collected, so the ratio itself does not automatically drop during a vacant month — but a lender's underwriting still cares about how much cushion exists to absorb one. A property at 1.0 DSCR has zero room: one late payment or vacant month puts the owner in the hole. A property at 1.35 can absorb a partial-month vacancy or a rate increase and still cash flow.

Insurance costs, especially in areas with elevated wind, hail, or flood risk, can materially change PITIA and therefore DSCR. A jump in annual premium from $1,800 to $3,600 adds $150/month to PITIA, which on a $2,300 rent and $2,000 base PITIA would drop DSCR from 1.15 to about 1.07. Investors should always get a firm insurance quote before finalizing a purchase price or offer, since insurance swings are one of the most common reasons a deal's DSCR comes in lower than initially projected.

How to improve a failing DSCR

If a property's DSCR comes in below the lender's minimum, there are several practical levers to pull rather than walking away from the deal.

• •Increase the down payment to reduce the loan amount and monthly P&I
• •Negotiate a lower purchase price so the loan amount, and thus the payment, shrinks
• •Shop insurance carriers — premiums for the same property can vary significantly
• •Verify the market rent is not underestimated; a fresh comparable rent survey sometimes shows a higher achievable rent
• •Consider an interest-only DSCR structure where available, which lowers the monthly payment used in the ratio
• •Appeal or protest the property tax assessment if it appears inflated relative to comparable properties

Why investors choose DSCR loans

DSCR loans exist because rental property performance, not the owner's W-2, is what actually pays the mortgage. Curlee Capital, as a direct private lender based in Austin, underwrites DSCR rental loans in-house against the property's cash flow, with no tax returns or employment verification required, terms including 30-year fixed, 5/1, and 7/1 ARM options. Up to 75% LTV. Your exact limit depends on credit profile and property type — single family, condo, or 2–4 units — and is confirmed by your Deal Advisor. Loans can close in an LLC or personal name, which matters for investors building a portfolio for liability and financing-scale reasons.
