T12 (Trailing Twelve Months)
A T12, or trailing twelve months statement, is a property's income and expense report covering the most recent twelve months, usually broken out month by month. It shows what the property actually earned and spent over a full year, which makes it the reality check for every forward-looking number in underwriting.
Why a T12 matters
A single month can make a property look better or worse than it is. Twelve months captures a full cycle of seasonal expenses, lease turnover and one-time items, so the T12 gives a truer picture of how the property performs.
Underwriters use the T12 in two ways. They reconcile it against the rent roll, so that the rent tenants are contracted to pay matches what was actually collected. They also compare it against the pro forma, so that any projected improvement is backed by a clear reason.
Month-by-month detail matters. It shows trends that an annual total hides, such as rising vacancy, climbing insurance costs or a jump in concessions late in the year.
T12 vs. Pro Forma
A T12 records what a property did over the past year. A pro forma projects what it could do under a set of assumptions. Lenders generally size loans on actual performance, while investors may pay for pro forma upside, so the gap between the two is where many underwriting debates happen.
Where it matters by property type
T12 review is central to multifamily and affordable housing underwriting, where expenses and collections change from month to month.

Frequently asked questions
What does a T12 include?
A T12 lists each month's income, such as rent, fees and other income, and each month's operating expenses, such as taxes, insurance, utilities, repairs, payroll and management. It typically ends with net operating income for each month and a twelve-month total. Some T12s also show capital spending below the net operating income line.
What is the difference between a T12 and a T3?
A T12 covers the trailing twelve months, while a T3 covers the trailing three months. Underwriters often annualize T3 income to show where the property is heading right now, and use the T12 for expenses, which vary by season. Comparing the two shows whether performance is improving or slipping.
Who provides the T12?
The property owner or property manager prepares the T12, usually from the property's accounting system. Sellers provide it during a sale, and borrowers provide it with a loan application and in regular reports to their lender. Lenders often ask borrowers to certify the statement or support it with bank records.
