The DSCR Investor Operating System

Scale your rental portfolio without DTI limits.

A conventional lender caps how many rentals you can own using your DTI — debt-to-income, the share of your paycheck already committed to debt payments.

Adjust any property's monthly rent and payment below. The 1.00x line is break-even — rent exactly equals the payment. A new door arrives with its own rent and its own ratio, and changes nothing about the ones already there.

Model Portfolio Strategy
What a DSCR lender looks at

What each deal is judged on.

Each deal is judged on its coverage, your credit score, the cash you hold after closing, and whether you buy in your own name or through an LLC.

  • The rent against the payment

    Qualifying rent divided by the full monthly payment (PITIA). 1.00x is break-even; 1.25x is strong coverage, where best-tier pricing starts.

    How DSCR is calculated
  • You, not your paycheck

    Your paycheck stays out of it. The credit, reserve and vesting rules are set program by program.

    Credit, reserves and vesting
  • The property

    Every rental model has a different income story, operating burden, and leverage ceiling.

Why this lane fits

Single Family Residential is the bedrock of DSCR lending. Qualification is 100% property-based using appraised market rent (FNMA Form 1007) or active lease agreement.

A 30-Year Fixed DSCR loan locks low debt service for three decades with no refinancing risk. Switch to a 5/6 ARM if initial rate buydown is needed to clear 1.25x DSCR.

Buy-and-Hold Investors seeking long-term debt lock with zero W-2/Tax Return friction.

Tax edge, trade-offs and the decision checkpoint

What it gives you, what it costs, what to check first

Reclassify 20–25% of building basis into 5/7/15-year bonus depreciation under the 2025 tax law rules, creating massive year-1 passive loss offsets. Using them against wages and other ordinary income generally takes real estate professional status plus material participation in the rental, or material participation in a short-term rental; otherwise the passive-loss limits apply.

Advantages. Deep tenant demand and familiar lease structures in most markets Straightforward comparable sales can support valuation and resale Simpler operations than multi-tenant or mixed-use properties

Trade-offs. One vacancy can remove the property's entire rental income A major repair is supported by only one rent stream Scaling a scattered portfolio can increase travel and vendor complexity

Before you commit. Stress one full vacancy, a major system replacement, and realistic property-management costs before relying on the headline cash flow.

Terms assessed on every file

The five rows a lender reads for this property type
  • Best loan structure: 30-Year Fixed or 5/6 ARM
  • Qualifying income: LOWER of Signed Lease or Form 1007 Appraisal Market Rent
  • No personal tax returns, W-2s, or DTI calculation required
  • Qualify at 0.75x–1.00x DSCR with LTV adjustments (up to 80% LTV at 1.25x+)
  • Borrower can vest in an LLC, S-Corp, C-Corp, or Individual name
  • Prepayment-penalty rules encoded for 47 states and DC, each with its statutory citation — including the common 5/4/3/2/1 and 3/2/1 step-downs, where the fee shrinks every year you hold the loan

DSCR Underwriting & Dual-Track Science

How Coverage Ratio Dictates Your Rate & Max LTV

Greenstreet models every deal on Dual-Track DSCR Science. Track 1 measures Lender Approval Qualification (Gross Rent ÷ PITIA). Track 2 measures Real Investor Net Cash Flow (factoring 7% vacancy, 8% property management, 8% maintenance and 5% capital-expenditure reserves, and property tax reassessments).

Two ways to measure coverage

Track 1 qualifies the loan; Track 2 is your real cash flow
Track 1: Lender Qualification DSCR
Qualifying Rent ÷ PITIA
Lower of Signed Lease or Form 1007 Appraisal. Determines loan approval, max LTV, and pricing tier.
Track 2: Investor Net Survival DSCR
Rent × 72% ÷ PITIA
Catches the deal that qualifies on paper and still loses money every month — Track 1 passes, Track 2 comes back negative, and the calculator says so before you sign. Shown for a single-family rental, average condition, normal market — the engine's own default; other property types, ages and markets carry a different haircut.

Illustrative tiers, and what Min FICO means

Illustrative pricing tiers, not a live rate sheet — actual pricing runs through Greenstreet's engine and each program's own matrix. Scope: tiers from 640; programs start at 620.

Min FICO is the lowest published eligibility floor for that DSCR tier; credit score also changes the rate — see the rate bands.
