Net Operating Income (NOI)

NOI: What the Market Actually Requires

Every underwriting metric that matters, cap rate, DSCR, debt yield, starts with NOI, and lenders never take the borrower's number. Underwritten NOI is rebuilt line by line: a vacancy and collection loss floor (commonly 5%) even when the rent roll is full, a management fee of 3% to 5% even for self-managed properties, replacement reserves (roughly $250 per unit per year on multifamily, and a per-square-foot allowance on commercial), real estate taxes reassessed to the new purchase price in reassessment states, and haircuts to income that is short-term, above-market, or non-recurring. The gap between borrower NOI and underwritten NOI is routinely 5% to 10%, and that gap is pure loan proceeds.

The arithmetic explains the intensity. At a 10% debt yield floor, each additional dollar of underwritten NOI supports ten dollars of loan, and a 1.25x DSCR test gives a single dollar similar leverage. On a $900,000 NOI property, defending $50,000 of contested income is worth roughly $500,000 of proceeds. Capital sources apply the rebuild differently: agency lenders run standardized adjustment grids, CMBS underwriters mark income to signed leases or market rents, whichever is worse, banks lean on the trailing twelve months, and bridge lenders will credit a stabilized pro-forma NOI but size the initial advance to in-place income.

Borrowers lose proceeds through avoidable mistakes: classifying recurring maintenance as capital expense to inflate NOI (underwriters reclassify it and then distrust the rest of the statement), submitting pro-forma rents without executed leases, forgetting the tax reassessment, and delivering a messy T12 that invites conservative assumptions. The preparation that pays: a clean trailing twelve months, a current certified rent roll, documented other income, and a defensible expense story before the file ever reaches a credit desk.

Why It Matters for Your Loan

NOI is the single number with the most dollars attached to it in a financing. It sets value through the cap rate, coverage through DSCR, and proceeds through debt yield, so every defended dollar of income compounds three ways. The difference between a prepared operating statement and a sloppy one is frequently hundreds of thousands of dollars in loan proceeds on the same building. Commercial Lending Solutions pre-underwrites NOI to each target lender's own adjustment conventions before submission, so the number that reaches committee is the one the deal was sized on.
