5–25 Unit Commercial Multifamily DSCR Underwriting
Bottom Line Up Front (BLUF): Unlike 1–4 unit residential DSCR (which divides gross rent by PITIA), 5+ unit commercial multifamily DSCR is underwritten on Net Operating Income (NOI): Gross Potential Rent minus a 5%–10% vacancy factor and operating expenses divided by annual debt service.
Underwriting Formula / Rule
Commercial DSCR = Annual Net Operating Income (NOI) ÷ Annual Debt Service (P&I).
Wholesale Shelf Benchmark
1.20x–1.25x NOI DSCR up to 75% LTV across commercial wholesale shelves.
