The rent roll is the single most scrutinized document in commercial underwriting. It's a snapshot of every unit's income, and a lender reads it to answer one question: is this income real, and will it last?
What's on it
Unit by unit: the tenant, lease start and end dates, current rent, any concessions, security deposit, and — for apartments — the unit's regulatory status. Add it up and you get gross potential rent; subtract vacancy and operating expenses and you reach net operating income, the number that sizes the loan.
What a lender is checking
Occupancy and its trend — a building 95% leased on long remaining terms underwrites very differently from one at 80% with leases rolling next quarter. Bunched lease expirations signal rollover risk, and in-place rents versus market rents tell the lender whether the income is sustainable or propped up.
Lenders reconcile the rent roll against the trailing 12 months of actual collections. If the roll says one thing and the bank deposits say another, the deposits win.
Red flags that slow a deal
Month-to-month tenants, related-party or non-arm's-length leases, large concessions that inflate face rents, and 'other income' that can't be documented. None is a dealbreaker alone, but each invites questions — and questions cost time on a rate lock.
Clean it up before you apply
Deliver a current, accurate rent roll with the trailing-12 statements that back it up, and flag anything unusual before the lender finds it. A clean file signals a serious borrower and keeps underwriting fast. See the document checklist for the full list, then get matched.
