How to read a T12 real estate operating statement

Verify that the report contains twelve distinct, consecutive months and note whether it is prepared on a cash or accrual basis. Check that account subtotals and the annual column foot. A T12 assembled from multiple exports may contain a duplicated month, a partial month, or a year-to-date column mislabeled as a trailing period.

Retain the seller's original chart of accounts. Build a separate mapping layer rather than renaming source rows in place. This lets you standardize inconsistent labels—such as turnover, make-ready, and unit prep—without losing the audit trail.

An annual total can hide the exact event that matters. Review monthly values for step-changes and clusters: a utility spike, a tax refund, a large insurance payment, a property-tax reassessment, or several months of depressed collections. Compare each unusual period with the surrounding months and request support before annualizing it away.

Revenue should be cross-checked against the rent roll at a consistent date. The files will rarely match perfectly because one is a point-in-time lease schedule and the other is a period statement. The difference should still be explainable through vacancy, concessions, bad debt, timing, and non-rent income.

Normalization is appropriate when the historical figure does not represent continued ownership, but each adjustment needs a reason. Remove a genuine one-time legal expense; do not erase recurring legal cost because it makes the cap rate look better. Replace current insurance or taxes only when a quote, reassessment method, or other defensible basis supports the change.

Present reported NOI and underwritten NOI side by side, with a bridge between them. This makes the acquisition thesis falsifiable: reviewers can see whether value is coming from current operations, expense corrections, rent growth, or a future business plan.
