What is an offering memorandum (OM)?

What an OM contains

OM formats vary by broker and asset class, but the table of contents is remarkably consistent. So is the right level of trust for each section.

Two sections carry most of the underwriting weight. The rent roll and T-12 are the property's actual record, and the gap between them and the pro forma is where the broker's argument lives. A pro forma that jumps NOI 20 percent in year one is asserting that the current owner left that much on the table, which is sometimes true and always worth pricing skeptically.

Who prepares the OM, and why it reads the way it does

The listing broker prepares the OM, with the seller supplying the raw material: rent roll, operating statements, capital history, and property information. On institutional listings, a brokerage marketing team produces a designed document that can run past 50 pages; on smaller deals it may be 10 pages of template. Distribution is gated, with the full OM released after a prospective buyer signs a confidentiality agreement, and the document typically lives in the listing's deal room alongside the early diligence set.

Authorship explains the document. The broker is paid by the seller to achieve the best price, so an OM is advocacy built on real data: the strongest defensible version of the property's story. That is not a defect, and experienced buyers do not resent it. They just read it the way it was written, and every OM's own disclaimer says the same thing, that the information is not guaranteed and buyers must verify it independently.

One nearby distinction matters. A sale OM is marketing. A private placement memorandum (PPM), used to raise equity from investors under securities law, is a legal disclosure document with liability attached. Sponsors sometimes call a PPM an "offering memorandum," so confirm which instrument you are holding before you rely on either.

How to read an OM: trust, verify, ignore

A useful discipline is to sort every OM claim into three buckets before underwriting starts.

Trust, then confirm in DD: physical facts (unit count, square footage, year built) and legal facts (parcel, zoning designation). These are checkable and brokers rarely shade them, because getting caught is expensive.

Verify now, in screening: everything financial. Recompute the in-place cap rate from the T-12 rather than accepting the summary page. Check the rent roll's as-of date. And check every "market" number against a published source, because market claims are where selective framing is easiest.

A live example of why: for the same market and quarter, Q1 2026 Dallas-Fort Worth multifamily, Northmarq reported average cap rates around 5.25 percent with a median price of $175,300 per unit, while Matthews reported a 5.8 percent average cap rate, $183K per unit, and 12.2 percent vacancy. Neither is wrong; they draw from different transaction sets and methodologies. An OM quoting "market cap rate of 5.25 percent" for a DFW deal has simply chosen the survey that flatters the price by half a point. If you do not ask which survey, the OM has chosen for you.

Ignore: the adjectives. "Irreplaceable location," "significant upside," and "pride of ownership" have never changed an underwriting outcome.

OM vs BOV vs appraisal

Three documents put a value story on the same property, and they differ in author, purpose, and accountability.

The broker opinion of value often comes first in a deal's life: an owner asks brokers what the asset could fetch, the winning broker's BOV becomes the pricing basis, and the OM is built to defend it. The appraisal arrives last, ordered by the buyer's lender, and is the one document whose author is professionally accountable for the number. When the appraisal and the OM disagree, the loan sizes to the appraisal.

How acquisitions teams process OMs

The market context sets the volume. 176,445 U.S. commercial properties traded in 2025 for $560.2 billion, per Altus Group, and momentum carried into 2026 with Q1 volume of $117 billion, up 19 percent year over year, per CBRE. Behind each marketed trade sits an OM that went to dozens of buyers, so an acquisitions team with decent broker coverage sees 10 to 20 OMs a month, and most deserve a fast no.

Run the arithmetic on 15 OMs a month. A 30 to 45 minute first-pass read is 8 to 11 hours a month of reading alone, before any deal advances. The teams that handle the volume well share two habits. First, a written buy box that turns most first passes into 10-minute screening decisions: asset class, market, size, and a quick cap rate check against the box. Second, a log, because an OM passed on in March gets re-traded in September, and knowing what you thought the first time is worth real money.

Building an OM intake habit

Teams that see hundreds of OMs a year treat intake as a process rather than an event. The habit worth copying: every OM that passes the first look gets logged as a deal record the day it arrives, with the asking terms, the broker, and the screening verdict captured while the context is fresh. The OM file itself gets stored with the deal, not in someone's downloads folder, so that when the property trades and comes back to market in three years, the team's prior read is one search away. The half hour a week this costs pays for itself the first time a broker calls about a deal the team already screened.

That second habit is where deal management software earns its place. In MotionCRE, each incoming OM becomes a deal in the screening stage of the pipeline with the OM attached to the deal record, so the pass is recorded with a reason instead of evaporating. The AI Associate can chat over the deal's files, which for a 60-page OM means asking for the T-12 NOI, the rent roll date, or the pro forma's expense assumptions instead of hunting for them page by page. The OM is the industry's inbox; the teams that treat it as a queue to be worked, rather than a pile to be remembered, screen more deals with the same people.
