Common OM Mistakes

Why OM mistakes are expensive

An error in an offering memorandum does not just cost you the point it gets wrong. It costs you the reader's trust in every other number in the document.

Investors underwriting a deal are running a continuous credibility assessment. Each figure they can verify raises confidence; each one that does not hold up lowers it disproportionately. A single reconciliation error on page nineteen will send a careful analyst back to re-check the executive summary, and it becomes a negotiating point later.

The mistakes below are ordered by how often they appear in circulated memorandums and how much damage they do. Most are process failures rather than knowledge failures, which is why the last section is about the review process rather than about writing better.

Numbers that do not reconcile

The most common and most damaging error.

The typical version: the asking price changes 48 hours before launch. Someone updates the financial section and the pricing table. The executive summary still shows the old cap rate. A chart on page four still uses the prior net operating income.

Other frequent reconciliation failures:

• Rent roll total does not equal the income line in the operating statement
• Occupancy percentage disagrees with the tenancy detail
• Square footage differs between the property overview, the financial tables, and a map label
• Unit counts differ between sections
• Cap rate does not calculate from the stated price and net operating income

Why it happens. The same figure exists in five places, maintained by hand. Any late change has five opportunities to be missed, and the executive summary is missed most often because it is written first.

The fix. Reconciliation checks catch it, but they are a mitigation. The structural fix is deriving every figure from one record so the same number cannot appear in two versions. Our offering memorandum checklist covers the manual checks in the meantime.

Burying the investment thesis

Many memorandums never state, in one place, why the asset is worth the price.

The information is present, scattered across highlights, financials, and market commentary, and the reader is expected to assemble it. Most will not. They will form their own thesis, which may not be the one you would have argued.

What buried looks like: an executive summary that lists metrics without an argument, followed by seven highlights that are mostly adjectives.

What stated looks like: "In-place rents average 18 percent below the five most recent comparable leases, with 62 percent of the rent roll rolling within 30 months, offering a mark-to-market opportunity without capital investment."

The second version gives the buyer something to test. That is the point.

Stale market and demographic data

Reused sections are the main vector. A demographics page or submarket overview carried forward from a prior deal looks perfectly current until someone checks the vintage.

Signals investors notice:

• Demographic figures without a source or a date
• Employment data predating recent, well-known market changes
• Comparable sales more than 18 months old presented as current evidence
• Traffic counts from a study nobody can locate
• Submarket vacancy quoted without a period

Why it matters beyond accuracy. Stale data signals that the memorandum was assembled rather than researched. Once a buyer concludes that, they read everything else with more suspicion.

The fix. Require a source and a date on every statistic. Generate market data at production time rather than copying it forward. Anything that cannot be sourced comes out.

Unsupported pro forma assumptions

Aggressive projections are not the problem. Unstated ones are.

A pro forma showing meaningful rent growth is fine if it names the comparable leases supporting it. The same pro forma with no support invites the buyer to construct their own, which will be more conservative than yours.

Assumptions that must be stated explicitly:

• Market rent and the specific comparables supporting it
• Vacancy and credit loss factor
• Expense growth rate
• Management fee, whether or not currently paid
• Replacement reserves
• Lease-up timing and downtime between tenants
• Any capital expenditure required to achieve projected rents

That last one is frequently omitted. A pro forma that assumes renovated rents without showing the renovation cost is not a projection, and sophisticated buyers treat it as an attempt to mislead rather than an oversight.

Also: never blend actuals and pro forma in one column. Label them separately, always.

Ignoring the obvious objection

Every asset has a weakness a buyer will identify within ten minutes: short remaining lease term, tenant concentration, deferred maintenance, a soft submarket, an odd floor plate, limited parking.

Memorandums routinely say nothing about it.

This never works. The buyer finds it during diligence, and the omission reads as concealment rather than salesmanship. You also lose the chance to frame it.

Addressing it directly costs a paragraph and buys credibility: name the issue, give the relevant facts, and explain how it is mitigated or already reflected in the price. Deals close faster when the difficult conversation happens on page six instead of during a call three weeks in.

Brand drift and version chaos

Two operational failures that compound.

Brand drift. Five people producing memorandums against editable templates will produce five slightly different documents. Logo placement moves, a heading font changes, contact blocks get formatted differently. Individually trivial, collectively they make a firm look disorganized to institutional buyers who see a lot of material.

Version chaos. A shared drive with four PDFs, all dated, all slightly different. Someone sends the wrong one. This happens more often than firms admit, and it is occasionally serious: a superseded version with old pricing, or a full memorandum sent to a party who only signed for the teaser.

The fix for both is structural. Lock brand elements in the template so they cannot be edited. Maintain one current version generated from one record rather than files copied and edited. Our offering memorandum template guide covers what to lock and what to leave dynamic.

Weak or missing disclaimers

Disclaimer language gets treated as boilerplate and then quietly degrades.

Common failures:

• Confidentiality language present on the teaser but missing from the full memorandum, or the reverse
• The wrong legal entity named as seller
• Language edited per deal by someone without authority to edit it
• Forward-looking projections not labeled as projections
• Statements about entitlements, permitted use, or condition presented as fact without qualification
• Missing brokerage licensing disclosures required in your jurisdiction

The fix. Have counsel approve one standard set of language. Lock it in the template as non-editable. Review it annually rather than per deal. Editable legal text will eventually be edited, usually at 11 pm before a launch.

Building a review process that catches these

Most of these mistakes survive because review is informal. Make it structural.

Three mandatory passes:

1. Numbers. The person who built the financials verifies every figure against source documents, checking reconciliation specifically.
2. Positioning. The listing broker confirms the thesis is stated, the objection is addressed, and the buyer profile matches the story.
3. Cold read. Someone who did not work on the document reads it start to finish for sense, not for errors.

Two structural safeguards:

• Approval gates. The document cannot be exported or shared until reviewers have signed off. Enforced by workflow, not by discipline.
• One data source. Most items in the first pass exist only because the same number is entered in several places. When every section derives from one structured listing record, whole categories of error become impossible rather than merely unlikely. That is the practical case for Offering memorandum software over assembling documents by hand.

Track what you catch. If the same category of error appears three listings running, fix the upstream cause instead of relying on catching it again.

To test how many of these failure modes your current process actually prevents, try with one listing and run a late pricing change through it, or book a demo with a memorandum you have already sent. More detail on Offering memorandum software.
