How to read a T-12 the way an underwriter does
The T-12 is the first document you open and the easiest to misread. A field guide to the lines that move a deal — and the ones sellers lean on.
NOI reconciliation: closing the gap between reported and reconstructed
Reported NOI and the NOI you can rebuild from source documents rarely match. Reconciling the two — line by line — is where underwriting conviction actually comes from.
Every offering memorandum states a net operating income. Every T-12 states one too. And the NOI you can reconstruct from the rent roll and the operating statement is a third number. Underwriting conviction does not come from picking one of the three — it comes from reconciling them and understanding precisely why they differ.
Why the numbers diverge
The gap between reported and reconstructed NOI is not usually fraud. It is the accumulation of ordinary framing choices: a management fee assumption, a market-rent line applied to vacant units, taxes held at the seller's basis, capital items reclassified below the NOI line. Each is individually defensible and collectively material. Reconciliation is the discipline of naming each contributor to the gap.
A gap you can explain is an asset
A reconciled $140K difference you can attribute to three specific lines is far more useful than a single NOI you cannot defend. The explanation is the underwriting.
A reconciliation that holds up
- Rebuild effective gross income from the rent roll — actual leases, concessions, and economic vacancy.
- Normalize each expense line to what a new owner will pay, flagging taxes, insurance, and management.
- Compute a reconstructed NOI and place it beside the reported figure.
- Attribute every dollar of the difference to a named line — no residual 'other'.
- Keep anything that does not reconcile visible as an open item, not buried.
Cap rate at ask, honestly
Once you have a reconstructed NOI you can defend, the cap rate at the asking price becomes an honest number rather than a marketing one. Dividing your reconstructed NOI by the ask — not the seller's NOI by the ask — is often the single most clarifying calculation in the entire review, and it frequently reframes whether the deal is worth pursuing at all.
This is the core of how InvestAssist reads a deal: reported and reconstructed side by side, every difference attributed, and nothing that fails to reconcile quietly dropped. For the document-level mechanics that feed this, start with reading the T-12 and analyzing the rent roll.
