CRE Debt Yield & Tripartite Loan Sizing Underwriter
Institutional commercial mortgage sizing engine. Simultaneously calculates maximum borrowing capacity across the three mandatory credit committee covenants: Debt Yield (NOI / Loan), Debt Service Coverage Ratio (DSCR), and Loan-to-Value (LTV) to pinpoint the governing bottleneck and required equity check.

CRE Debt Yield & Tripartite Loan Sizing Underwriter
This institutional underwriting engine calculates commercial real estate loan capacity by simultaneously evaluating the three primary credit committee covenants: Debt Yield (NOI / Loan), Debt Service Coverage Ratio (DSCR), and Loan-to-Value (LTV). Pinpoints the exact binding constraint bottleneck and computes required borrower equity injections.
Target Audience Application
Determine the true maximum debt capacity of multifamily, industrial, retail, or office assets before submitting loan applications to commercial banks, CMBS conduits, or life insurance lenders.
Stress-test debt service coverage, minimum debt yields, and exit refinancing feasibility across elevated floating-rate and permanent fixed-rate financing environments.
Package loan requests with institutional tripartite sizing summaries, identifying whether debt yield or DSCR is the restrictive sizing governor.
Evaluate commercial real estate debt risk, equity-gap exposure, and capital stack structures across private real estate funds and direct syndications.
Master the practical credit mechanics of commercial underwriting, understanding why debt yield provides a pure cash-on-cash metric independent of interest rates and cap rates.
Tripartite Commercial Loan Sizing Equations
Max LoanDY = Net Operating Income (NOI) / Minimum Required Debt Yield2. Maximum Loan by Debt Service Coverage Ratio (DSCR):
Max LoanDSCR = Net Operating Income (NOI) / (Target DSCR × Annual Loan Constant)3. Maximum Loan by Loan-to-Value (LTV):
Max LoanLTV = Appraised Property Value × Maximum Permissible LTV4. Binding Credit Committee Sizing Decision:
Approved Loan Amount = min(Max LoanDY, Max LoanDSCR, Max LoanLTV)
Institutional Lending Standards & Underwriting Hurdles
- Debt Yield Sizing Floor: CMBS conduits typically mandate 10.0% to 11.5% debt yields; regional banks require 9.5% to 10.5%; conservative life companies accept 8.5% to 9.5% for prime core assets.
- DSCR Underwriting Floor: Standard commercial bank floor is 1.25x to 1.35x based on amortizing debt service.
- Maximum LTV Ceilings: Conventional commercial loans rarely exceed 65% to 75% LTV in restrictive monetary policy regimes.
- The Binding Constraint Bottleneck: The lowest loan amount of the three tests governs. The difference between purchase price and approved debt constitutes the mandatory borrower equity check.
