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. A DSCR loan asks a different question: does this property's rent cover this property's mortgage payment? Each deal is judged on that coverage, your credit score, the cash you hold after closing, and whether you buy in your own name or through an LLC.

Each property qualifies on its own rent.

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.

Property & investment strategy field guide

Choose the property. Then choose the debt.

Every rental model has a different income story, operating burden, and leverage ceiling. Select a property lens to see the case for it, the friction against it, and the evidence an underwriter will ask for.

01/ 10 lenses

Reserves are months of PITIA liquidity. An em dash means that lens is assessed per file — the numbers are set on the deal, not that leverage is unavailable. Figures are program parameters shown for comparison across property types, not an offer of credit. Greenstreet is a mortgage broker; terms, pricing, and eligibility are set by the lender on each file.

Lens 01 · Rental DSCR Scenario

Single Family Rental (SFR)

1-Unit Detached Homes, Townhomes & PUDs

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.

Built for
Buy-and-Hold Investors seeking long-term debt lock with zero W-2/Tax Return friction.
Debt path
30-Year Fixed or 5/6 ARM
Income evidence
LOWER of Signed Lease or Form 1007 Appraisal Market Rent

Why this loan fits

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.

Tax and depreciation note

Reclassify 20–25% of building basis into 5/7/15-year bonus depreciation under OBBBA rules, creating massive year-1 passive loss offsets.

Decision checkpoint

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

The investment case

  • 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

The operating friction

  • 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
What the underwriter will ask for
Set by the lender on each file.
  1. 01

    No personal tax returns, W-2s, or DTI calculation required

  2. 02

    Qualify at 0.75x–1.00x DSCR with LTV adjustments (up to 80% LTV at 1.25x+)

  3. 03

    Borrower can vest in an LLC, S-Corp, C-Corp, or Individual name

  4. 04

    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

Take the next step

Price it against the actual deal.

Run coverage, payment, and lender-program logic against the actual deal—not the headline rent.

The DSCR Investor Underwriting Standard

Everything a DSCR Investor Needs to Know

No W-2s, no personal tax returns, and zero DTI calculations. Underwrite deals strictly on property rental coverage, credit score, reserves, and LLC vesting.

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 8% vacancy, 8% property management, maintenance reserves, and property tax reassessments).

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 × 92% - Mgmt - Maintenance) ÷ 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.
