Working through a DSCR that won't clear on a 10-unit no matter how the numbers get stacked
A useful exercise in underwriting a small rural multifamily deal: a 10-unit building priced by the seller off a stated NOI and cap rate, with real numbers reconstructed independently from bank deposit history rather than the seller's own books. Working it from scratch with a realistic vacancy and credit loss assumption for a thin rural market, and an expense ratio that accounts for the owner paying water, sewer, trash, and heating the common areas, tends to produce an NOI meaningfully below what the seller is claiming. Against a lender's typical terms for this asset class, say 75 percent loan to value, 25 year amortization, a 5 year term, and a 1.25x DSCR requirement, the resulting debt service on a loan sized to that lower NOI often fails the coverage test entirely at the seller's asking price. The useful number to work backward from is what loan amount actually clears 1.25x at the quoted rate, and then what down payment that implies at the asking price. In a market with real underwriting risk and no recent comparable sales to lean on, that down payment often lands well above what would be palatable, sometimes 40 percent or more. Two current vacancies rented at a stated market rate the seller hasn't tested are a real lever, but pro forma rent should never substitute for in-place rent in a DSCR calculation, since the lender will not underwrite to a number nobody has actually collected. The honest next step is usually going back with an offer anchored to the buyer's own reconstructed NOI, not the seller's, since a market with no recent comparable sales gives the buyer little reason to defer to a number they can't verify.
