T12 (Trailing Twelve Month Operating Statement)
A T12, or trailing twelve month operating statement, reports a property's or business's actual income and expenses month by month for the most recent twelve months. Underwriters use it, together with the rent roll, as the primary evidence of current performance and as the starting point for underwritten net operating income.
Example
A T12 for an apartment property shows rental income of $1,380,000, other income of $60,000 and operating expenses of $620,000, for trailing NOI of $820,000. The underwriter finds that property taxes of $90,000 will rise to $140,000 after reassessment on sale and that no management fee is charged. Deducting a 3% management fee on $1,440,000 of income ($43,200) and the $50,000 tax increase reduces underwritten NOI to $726,800.
How it is used in underwriting
A T12 is more reliable than a calendar year statement for a property that is changing, because it reflects the latest leasing, rents and expenses. Underwriters read it monthly, not just in total, looking for trends such as rising concessions, falling occupancy or unusual expense spikes. They reconcile income to the rent roll and, where possible, to bank deposits, then normalize expenses: adding a market management fee, adjusting taxes and insurance to post-closing levels, removing one-time repairs and adding a replacement reserve. The result is underwritten NOI used for valuation, DSCR and debt yield.
Common red flags include income that is higher than the rent roll supports, expenses that are suspiciously low or missing entire categories, capital items buried in repairs or vice versa, and annualized figures presented as a T12. Some sellers provide a T3 or T6 annualized to show recent improvement; lenders typically weight the full T12 more heavily unless leasing has clearly stabilized. For operating businesses, the equivalent is trailing twelve month (TTM) financials, often built from monthly profit and loss statements and used to calculate TTM EBITDA for valuation and covenant testing.

Frequently asked questions
What is the difference between a T12 and a pro forma?
A T12 reports actual historical income and expenses for the last twelve months. A pro forma projects future income and expenses based on assumptions such as rent increases, lower vacancy or expense savings. Lenders size loans primarily on T12 results, while equity investors use pro formas to estimate upside.
Why do lenders want a T12 and a rent roll?
The T12 shows what the property actually earned and spent, and the rent roll shows the current leases that will produce future income. Together they let underwriters confirm income is real, identify trends, and build a sustainable NOI for sizing the loan and testing debt service coverage.
What is a T3 annualized?
A T3 annualized takes the last three months of income, multiplies it by four, and presents it as an annual figure. It can better reflect recent rent increases or lease-up, but it can also overstate performance if those months were unusually strong. Underwriters usually compare it with the full T12 before relying on it.
