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. Three more are marked leased with no deposit on file. A missing deposit is not proof of nonpayment, so those three are counted in neither the paying count nor the vacant count. They stay flagged as unresolved, as missing evidence, until the rent history confirms which side they belong on. That leaves 98 of 120 sites verified paying: 82 percent. Nothing about the park changed. Only the label did.

Reported vs paying occupancy, worked example (CrosstownOS Rent Roll Truth Check):

One further line in the post's example, sites leased with no deposit behind them, stays flagged as missing evidence rather than counted either way.

The four ways reported occupancy and paying occupancy diverge:

• Employee units: occupied, and nobody pays.
• Comps: occupied by arrangement, not by rent.
• Carried nonpayers: occupied, rent stopped, tenancy did not.
• Leased with no deposit: paper says occupied, the bank has never seen the money.

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. In our judgment, the rent roll is a document buyers often trust readily and verify late, and occupancy is where that misplaced trust can cost 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 six 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 82 percent paying occupancy is verified: it ties to deposits and collections that someone reviewed. Once the months behind a count like that are verified, the RV Revenue Reality Check starts there and finds what the revenue stabilizes at. The fifteen-site gap between the 113 reported sites and the 98 verified paying sites breaks into twelve explained sites, the employee units, comps, and carried nonpayers, and three unresolved sites that stay missing evidence until each one is explained, unit by unit. Any underwriting built on 94 percent is carrying an underwriting assumption, whether the model admits it or not.

One limit on the deposit method itself: deposits corroborate payment, they do not prove it. A deposit record can include amounts that are not lot rent, such as tax or utility pass-throughs, advance payments for a future month, or money the owner put into the account. That is why deposits are the starting point of the rebuild, checked against collections, the rent roll, and the leases, not the whole rebuild by themselves.

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 twelve points of phantom revenue. That phantom revenue flows straight into the valuation, the debt sizing, and the return projections.

Worked dollar line (part of the same illustrative scenario): at an illustrative lot rent of $450 per site per month, the fifteen-site gap between reported and verified paying occupancy is 15 times $450, which equals $6,750 per month, and $6,750 times 12 equals $81,000 per year of revenue the reported number implies and the deposits do not support. Capitalized at an illustrative 6 percent cap rate, $81,000 divided by 0.06 equals $1,350,000 of indicated value resting on sites that are not verified paying. 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.

Rebuilt from deposits, occupancy stops being the seller's adjective and becomes the buyer's number, and the price follows the number.

Sources and Limits

• Internal grounding: the rebuild order and the evidence labels in this piece come from the CrosstownOS ParkProof Standard. The method also draws on the Acquisition Signal research program and on operator-community research, with contributors anonymized.
• Physical versus paying occupancy: Primior's Commercial Real Estate Rent Roll Analysis makes the same distinction this piece is built on: physical and economic occupancy are different, a tenant can occupy a space while paying no rent, and both conditions should be recorded without netting them into one percentage. It also directs buyers to reconcile the roll to leases, collections, bank deposits, and operating statements.
• Mobile Home University: its due diligence doctrine, in The Truth About Mobile Home Park Due Diligence, is to make sure occupancy is as promised and to verify seller-supplied numbers from scratch rather than trust them.
• Limits: the 120-site park, its lot rent, and its cap rate are a labeled illustrative scenario with invented numbers, not a report on a real property. The three unresolved sites in the scenario are counted in neither the paying count nor the vacant count, because a missing deposit is neither verified payment nor proof of nonpayment. Deposits corroborate occupancy. They do not prove it, for the reasons stated in the rebuild section above.
