What Is an Offering Memorandum in Commercial Real Estate?

By Rahul Singh, Founder & CEO, DeshTek · Published September 30, 2026 · 5 min read

Quick answer: An offering memorandum (OM) is the document a seller's broker uses to market a commercial property to prospective buyers. It combines a property description, location and market overview, and a financial summary, so a buyer can decide whether to make an offer.

What an offering memorandum is for

When a commercial property is listed for sale, interested buyers first receive a short teaser. Those who sign a confidentiality agreement then receive the offering memorandum, which is the full sales document. Its job is to make the investment case clearly enough that a qualified buyer can move to a call, a tour and an offer.

It is both a marketing piece and a reference document. Buyers, their lenders and their advisors will read it closely, so it has to be persuasive and accurate at the same time.

What goes into an OM

Formats vary by firm and asset type, but most offering memorandums include:

Why financial presentation matters

Buyers price commercial property largely on income. The financial section should show current rents, lease expirations and expenses in a way that ties out to the rent roll and operating statements. Net operating income divided by price gives the capitalization (cap) rate, so any inconsistency in the numbers undermines confidence in the whole document.

Where projections or pro forma figures appear, they should be labeled clearly and separated from actual results.

Frequently asked questions

How long is a typical offering memorandum?

There is no fixed length. It depends on the asset and the complexity of the deal, and can range from a short summary for a small property to a long document for a large or multi-tenant asset.

What is the difference between an OM and a teaser?

A teaser is a brief, often anonymous summary sent to gauge interest. The OM is the full document shared after a buyer signs a confidentiality agreement.
