You've won the listing. The exclusive is signed, the fee is set, and one thing stands between you and the first buyer call: the offering memorandum.
Get it right and it does more for your credibility than anything else you send. It's the document buyers forward to their partners, their lender and their investment committee, with your name on every page. Here's what an OM is, what goes in one, and what separates a book that draws bids from one that gets skimmed.

What is an offering memorandum?
An offering memorandum (OM), also called a confidential information memorandum (CIM) or simply "the book," is the sales document a commercial real estate broker prepares to market an investment property to buyers.
It isn't a feature sheet. It's a financial prospectus for one asset, built so a buyer can underwrite the deal, line up financing and take it to committee. It does three jobs:
- Markets the asset. It tells the story of why this property is worth buying.
- Gives buyers the data. Rent roll, expenses and lease terms, everything they need to run their model.
- Sets the ground rules. The offer process, the terms of the sale and the confidentiality that comes with the information.
Who creates the OM?
The listing broker owns it. At the big shops, a senior broker frames the investment thesis and an analyst and marketing team build the book. At smaller shops, that's usually you.
The pieces come from three places:
- The seller: trailing 12-month (T-12) financials, the rent roll, leases and property information.
- The broker: the analysis, the pro forma, the narrative and the design.
- Vendors: the photographer, sometimes a designer, plus survey and environmental reports.
The key sections of a commercial real estate OM
Most OMs run 15 to 40 pages, depending on size and complexity. A strong one covers these sections.
1. Cover and executive summary
The cover sets the tone with a strong photo, the property name and address, and your branding. The executive summary is the one-page pitch: size, location, tenancy and the investment thesis.
Put price, cap rate and NOI where the buyer can see them immediately, next to the reason the deal works. Investors read a lot of books. Don't make them dig.
2. Property description and location
- Site: acreage, zoning, parking and visibility
- Building: year built, renovations, systems, roof and rentable SF
- Location: 1-, 3- and 5-mile demographics, access to highways and transit, and the employers and retailers nearby
3. Financial analysis
The heart of the book. Sophisticated buyers go straight here.
- Rent roll: every tenant, suite, SF, rent and lease date
- T-12: actual income and expenses for the trailing year
- Pro forma: the projected income and expenses, clearly labeled as projections
- Key metrics: NOI, cap rate and price per SF or per unit
Blurring actuals and projections is the fastest way to lose a buyer's trust. Label both.

4. Market analysis
Show that the building sits in a market worth owning: vacancy trends, absorption and rent comparables that support your pro forma.
5. Tenant profiles
For multi-tenant office, retail and industrial, tenant credit drives value. Summarize each major tenant's business, lease term remaining and options.
6. Maps, site plan and aerials
Visuals sell. A site plan shows the footprint, parking and access. An aerial or retail map with the logos of nearby retailers tells a buyer more about the trade area in five seconds than a page of text.

7. Confidentiality and offer terms
Every OM closes with the confidentiality language and the rules for submitting offers. This page protects the seller and tells buyers exactly how to bid.
Why the OM matters
You could just send the rent roll. You won't maximize value that way.
It creates competitive tension. A strong book released to a broad list of qualified buyers frames the asset at its best and gives several bidders a reason to sharpen their pencils.
It builds your buyer list. When buyers register or sign a confidentiality agreement to get the book, you know exactly who has it, which makes follow-up calls productive.
It sets the anchor. The asking price and the pro forma behind it frame the negotiation. A compelling book defends your number. A weak one invites buyers to chip away at it.
Common OM mistakes
- Numbers that don't match. If the cap rate on page 3 doesn't match the price and NOI on page 12, buyers question every number in the book.
- Weak photography. Dark, low-resolution phone photos read as amateur.
- No story. Is it a value-add play, a long-term hold, a development site? Say so.
- Fantasy pro formas. Project 10% annual rent growth in a 3% market and buyers will discount your entire model.
Building the OM without the InDesign marathon
For years the OM meant financials in Excel, pages in InDesign and a lot of retyping between them. Every hour spent nudging text boxes is an hour not spent prospecting.
In CREBuilder's offering memorandum builder, you type the address and the book starts building itself: building facts where data is available, 1-, 3- and 5-mile demographics, a market overview, a location map, and nearby transit, airports and highways. Enter the price and NOI and the cap rate calculates itself, then shows up on the cover, the executive summary metrics, the financial summary and the valuation page as the same number. Add the rent roll, pro forma and comps inside the OM, and watch the real pages build beside the editor.
Frequently asked questions
What does OM stand for in real estate?
Offering memorandum: the primary marketing document for a commercial investment property. It's also called a confidential information memorandum (CIM) or "the book."
What is an OM in commercial real estate?
A detailed sales document that combines a property's financials, rent roll, tenant profiles, market context and investment highlights in one package, so buyers have what they need to make an offer.
How long is an offering memorandum?
Usually 15 to 40 pages. Single-tenant net lease runs shorter; multi-tenant retail, office, multifamily and portfolios run longer because of the rent roll and tenant detail.
What is the difference between an offering memorandum and a prospectus?
An OM markets a specific property and is prepared by the listing broker. A prospectus is a formal securities document registered with the SEC to offer securities to the public. A property OM is a private real estate marketing document.
Is an offering memorandum the same as a CIM?
Yes. In commercial real estate the terms refer to the same document, and most brokerages use them interchangeably.
The book is your brand
The OM represents you, your analysis and your seller's asset. A polished, data-rich book tells a buyer they're dealing with a professional, and tells the next seller you're the broker to hire. Build your first OM free.
