Property Underwriting Tool · 47 States and DC

Enter an address and your numbers. Get a projected after-repair value range, DSCR (debt-service coverage ratio — whether rent covers the loan payment) run two ways — for the lender and for your actual cash flow — plus a certainty score bounded by both, and year-1 bonus depreciation under 2025's federal tax law (OBBBA).

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.
