Reported Occupancy Is Not Paying Occupancy

The scenario below is illustrative. A buyer is evaluating a 120-site park in the Southeast. The offering memorandum reports 94 percent occupancy, and the rent roll backs it up: 113 occupied sites. Ninety days into diligence, the buyer has rebuilt the number from bank deposits. Eight of those sites are employee units and comps. Four have not paid in over ninety days. That leaves 101 of 120 sites paying: 84 percent. Three more are marked leased with no deposit on file. A missing deposit is not proof of nonpayment, so they stay in the paying count, flagged as missing evidence until the rent history confirms it. Nothing about the park changed. Only the label did.

The working rule is simple: rebuild occupancy from deposits before the package's percentage carries any weight. Work backward from the money before reading another page.

These are not unusual stories. Ask around the industry and you will hear the same ones with different park names attached. The rent roll is a document buyers tend to trust most and verify least, and occupancy is where that misplaced trust costs the most.

Occupancy counts heads. Revenue counts dollars.

Reported occupancy answers one question: how many sites have someone on them. Paying occupancy answers the question the investment case actually asks: how many sites produce revenue. The two numbers diverge in predictable ways.

Employee units and manager sites. Comped sites given to friends, family, or long-term guests in exchange for work or goodwill. Tenants carried as occupied who have not paid in months, sometimes quarters. Sites marked leased where no deposit was ever collected. Each one is normal in park operations. Each one is invisible in a single occupancy percentage.

None of this is fraud. Most of it is just operations, recorded loosely, summarized generously. The problem is not that the 94 percent is a lie. The problem is that it was never the number the buyer needed.

Rebuild it from deposits

Verification starts at the end of the money trail and works backward. Bank deposits first, then the collections report, then the rent roll, then the leases. Every step backward is a chance for the numbers to disagree, and every disagreement is a question with a dollar figure attached.

Run the 120-site park through the four labels. The 94 percent occupancy is broker-reported: it appears in the memorandum and on the rent roll, and it has not been independently verified. The 84 percent paying occupancy is verified: it ties to deposits and collections that someone reviewed. The twelve-site gap is missing evidence until each site is explained, unit by unit. Any underwriting built on 94 percent is carrying an underwriting assumption, whether the model admits it or not.

Editor's note (2026-10-05): this note was written when the public language used four evidence states. The ParkProof Standard now uses six: Verified, Broker-reported, Missing evidence, Underwriting assumption, Calculated, and Unresolved.

This is the discipline from the first field note, applied to a single line item. Label every number. Verify what matters.

What the gap costs

A revenue model built on 94 percent occupancy prices ten points of phantom revenue. That phantom revenue flows straight into the valuation, the debt sizing, and the return projections. When the gap surfaces during diligence, it is leverage: a retrade grounded in labeled evidence is not adversarial, it is arithmetic. When the gap surfaces after closing, it is just a smaller return, discovered monthly, in the collections report.

The walk-away signal works the same way here as everywhere else. One non-paying tenant is operations. A pattern of carried balances, comped sites, and verbal arrangements, visible across the rent roll once it is rebuilt, is information about how the park was actually run. Labeled evidence makes the pattern visible before the earnest money is at risk.

The document buyers trust most

The rent roll earned its reputation. It looks authoritative: rows, columns, tenant names, balances. But a rent roll is a claim about the property, assembled by the seller, and it deserves the same treatment as every other claim in the package. Verify it, or label it honestly.

Start with deposits. End with the truth. Everything in between is just labeling.
