DSCR Qualification Mechanics: How We Tier Your File

The Core DSCR Formula

Debt Service Coverage Ratio is the foundation of how we underwrite income-producing real estate. The calculation is straightforward:

DSCR = Net Annual Rental Income ÷ Total Annual Debt Service

The numerator is gross rents minus operating expenses and vacancy reserves. The denominator is the total annual cost to service the loan: principal + interest + taxes + insurance + HOA fees (PITIA), if applicable. A DSCR of 1.25 means the property generates 25 cents of income for every dollar of debt obligation.

How We Count Rent

Rental income is the starting point. For long-term rentals, we typically use market rent or current lease terms, whichever is lower. We apply a conservative vacancy factor—usually 5 to 10 percent depending on market and property type—before we run the ratio. Some portfolios carry seasoned rent rolls; others are projections. The underwriter will verify the income method with tax returns, rent rolls, or lease copies.

Operating expenses are deducted. These include property management, maintenance, utilities (if landlord-paid), insurance, and local taxes. Owner-occupied expenses or personal use deductions do not apply here; we are looking at the cash the property actually generates for debt service.

Understanding PITIA

PITIA stands for principal, interest, taxes, and insurance. Annual debt service on a 30-year fixed loan includes both P&I (calculated using your loan amount, rate, and term) and the property-level T&I.

• Principal & Interest: Fixed monthly payment amortized over 360 months.
• Taxes: Annual property tax obligation divided by 12 for monthly reserve.
• Insurance: Annual hazard insurance premium divided by 12 for monthly reserve.
• HOA fees: If applicable, added to annual debt service (treated as a fixed obligation).

Total annual debt service = (monthly P&I × 12) + annual taxes + annual insurance + (annual HOA × 12, if any).

The Three Long-Term Rental Tiers

Once we calculate DSCR, your file lands in one of three tiers for our 30-year long-term rental program. Each tier has different credit, leverage, and rate requirements.

Tier 1: DSCR ≥ 1.25

This is the strongest credit tier. DSCR of 1.25 or higher means the property throws off 25 percent more income than it owes. You will need a minimum FICO of 740 and can borrow up to 65 percent LTV. Pricing starts from 5.75% with zero points. This tier is ideal for stabilized, cash-flowing properties with minimal seasoning risk and low loan-to-value positions.

Tier 2: DSCR ≥ 1.10

Middle tier. DSCR between 1.10 and 1.25. Requires FICO 720 minimum and allows up to 75 percent LTV. Pricing begins at 6.125%. This covers good performers with solid cash flow and moderate leverage. Most stabilized rental portfolios cluster in this tier.

Tier 3: DSCR ≥ 1.00

Weak cash-flow tier. DSCR between 1.00 and 1.10. The property covers its debt but has minimal margin. FICO floor is 680, and LTV can go to 80 percent. Pricing starts at 6.875%. This tier is for turnarounds, repositioning plays, or properties in transition where income is expected to improve post-lease-up.

Examples

Example 1: Tier 1 Candidate

Property generates $50,000 gross annual rent. Operating expenses are $12,000. Vacancy reserve at 5 percent: $2,500. Net rental income: $35,500. Loan amount $400,000 at 5.75% over 30 years: P&I is $2,336 per month ($28,032 annually). Property taxes: $3,600 per year. Insurance: $1,200 per year. Annual debt service: $28,032 + $3,600 + $1,200 = $32,832. DSCR = $35,500 ÷ $32,832 = 1.08. This file is Tier 2 (DSCR ≥ 1.10 not met, but 1.08 > 1.00, so it qualifies under Tier 3 rules if credit and LTV align).

Wait—recalculate. If gross rent is $50,000 and we want a DSCR above 1.25, we need net income of at least $41,040. That might require lower expenses or a lower loan amount. A 1.25 tier requires disciplined underwriting of both the income stream and the debt load.

Example 2: Tier 3 Candidate

New lease-up. Gross rent $30,000 (partially occupied). Expenses $8,000. Vacancy reserve $2,400. Net: $19,600. Loan $250,000 at 6.875% over 30 years: P&I $1,652 monthly ($19,824 annually). Taxes $2,400. Insurance $800. Debt service: $23,024. DSCR = $19,600 ÷ $23,024 = 0.85. This does not qualify—DSCR is below 1.00. The loan amount or rent assumption must improve before this file qualifies under any DSCR tier.

Other Programs: STR, Portfolio, and Commercial

Short-term rentals follow a different underwriting model; DSCR minimums are not published here because STR income is more volatile and requires seasoned cash-flow documentation. Bridge, fix & flip, and construction programs do not rely on current DSCR; they are structured on exit strategy and property as collateral.

Commercial DSCR, bank statement, and full documentation programs also have distinct tier structures that are not covered in this note.

Takeaway

Your tier placement determines your rate, how much you can borrow, and what credit profile you need. Start with accurate rent and expense numbers. Run the DSCR math early. If you land below 1.00, the deal may not work under DSCR programs—consider a bridge loan or restructure the property stack. We can issue a term sheet within 24 hours with no credit pull, so get the numbers in front of us and let's see where your deal fits.
