Net operating income
Income after operating expenses, before debt service. Lenders test how comfortably it covers the payment, which sets both the maximum loan and the pricing.
Once a building has five or more units, or its use turns commercial, it stops being underwritten like a house. The property’s income becomes the centre of the file, and the rules change accordingly.
Residential lending is largely about the borrower. Commercial lending is largely about the asset: what it earns, what it costs to run, and what is left to service debt. Lenders look at net operating income and how comfortably it covers the payment, alongside the quality and stability of the tenancy.
Terms look different too. Commercial loans frequently carry shorter terms than the amortization schedule, meaning a balloon payment or a required refinance at maturity. Knowing that date, and planning for it, is part of the deal rather than a surprise at the end.
For income property, the operating statement and rent roll do more work than anything else in the file. Accurate, current, well-organised figures will move a commercial loan faster than almost anything else you can control.
Commercial files turn on the property, the income, and the sponsor — in that order.

Occupancy, lease terms, and tenant quality. A building with staggered, stable leases underwrites very differently from one with everything expiring at once.
Your experience owning and operating similar property, plus liquidity and net worth. It matters, but it rarely overrides weak property numbers.
The line is unit count and use. One to four residential units is residential lending, even as an investment — which usually means better terms, longer fixed periods, and simpler paperwork, and often points to a DSCR loan. Five units and up, or a genuinely commercial use, moves you into commercial underwriting. If you are choosing between a fourplex and a six-unit, that decision affects your financing more than most buyers expect, and it is worth modelling both before you commit.
