Storage inventory and receipts
Self-storage research should show which spaces are occupied, how much area they represent and what rent was actually received. A high unit count can coexist with vacant large units or heavy move-in concessions. Use AI to organize unit types, contract charges and receipts while preserving the definitions that make occupancy and rental comparisons meaningful.

What changes the decision
Public Storage’s 2025 filing distinguishes square-foot occupancy from rental-income measures based on occupied and available area. Treat those definitions as an example of why a metric needs a denominator, not as a benchmark for another facility. Keep unit count, area and income measures separate, with the reporting period and the operator’s definition attached.
Source 1Posted rates, new-customer offers, existing-customer contract charges and actual receipts can differ. Record each category independently before comparing unit types or dates. AI can organize a supplied rate history, but it should not apply today’s advertised price to every occupied unit or present an introductory offer as a stabilized recurring charge.
Move-ins, move-outs, transfers and spaces taken offline affect both inventory and collections. Keep the event history rather than overwriting the prior status. A tenant moving between two units can otherwise appear as both new demand and unexplained vacancy. Tie promotions and adjustments to the corresponding occupancy period so changes remain reviewable.
Keep these separate
| Evidence or situation | What it tells you | What to establish next |
|---|---|---|
| Unit occupancy | Counts occupied units against a defined inventory | Review the size mix and offline units rather than assuming equal economic weight. |
| Area occupancy | Weights space by measured or recorded area | Reconcile unit dimensions and the operator’s available-area definition. |
| Achieved rental receipts | Reflects payments for a stated period | Separate promotions, arrears, fees and non-rent items before comparison. |
A worked review
| Measure | Fictional monthly file | Review decision |
|---|---|---|
| Inventory | Five 100-square-foot units and five 200-square-foot units: 10 units and 1,500 rentable square feet. | Keep unit count and area separate.Source 1 |
| Physical occupancy | All five small units and three large units are occupied: 8 / 10 = 80% by units; 1,100 / 1,500 = 73.3% by area. | Large-unit vacancy explains the difference.Source 1 |
| Rent collection | Assume full-inventory scheduled monthly rent of $1,500 and collections of $990. Collections / full-inventory rent = 66%. | This example defines its own collection ratio. Do not compare it with another operator’s economic occupancy without checking the definition.Source 1 |
| Promotions and cohorts | The occupied units have $1,100 scheduled rent; a $110 introductory concession leaves $990, assuming all remaining charges are collected. | Record move-in date and concession expiry before forecasting a later month.Source 1 |
| NOI scope | List facility operating costs, central allocations, insurance commissions and merchandise separately. | Use the stated NOI definition; rental collections alone are not NOI.Source 1 |
A practical review sequence
Use the sequence below to turn the initial description into specific document requests. Preserve contradictory records instead of choosing the more favorable version.
Request unit IDs, dimensions, climate or access attributes and rentable status. Reconcile the inventory to the operating system and available plans. Keep unusual spaces and offline units visible. Do not convert a nominal unit description into measured area without noting the basis and any discrepancy.
Obtain contract charges, dated advertised offers and a record of concessions or rate changes. Group comparisons by unit type and customer start period. This prevents a new-customer promotion from being used as evidence about the entire rent roll or an existing-customer increase from being mistaken for new lease demand.
Review a transfer, move-out and concession from event record to ledger. Ask for an anonymized reconciliation of rental charges, adjustments and receipts. Keep ancillary revenue separately classified. AI can flag inconsistencies, but a reviewer should determine whether the entry is a timing difference, a classification issue or missing evidence.
Request explanations for offline inventory, mismatched dimensions, unusual promotions and collection gaps. Give the manager and accountant the same dated worksheet. The tool produces a document-based review list, not a rent optimizer or forecast of future increases. Any later pricing model needs its own assumptions and testing.
Questions that arise during review
They answer different questions. Unit occupancy describes count, area occupancy describes space and economic measures describe revenue or collections under a stated definition. Keep all relevant definitions visible rather than selecting the most favorable percentage.
Advertisements provide limited, dated context and may contain conditions or promotions. They do not establish achieved rents or the subject facility’s response to a change. This kit organizes evidence and requests; it does not recommend or automatically apply prices.
Preserve separate categories first, including the agreement and accounting basis for each. A later analyst can create a clearly defined combined view. Combining items prematurely can make a rental comparison appear stronger without showing which receipts actually changed.
Different unit sizes, prices, concessions and collections change the denominator. In the fictional example, 80% of units are occupied but only 73.3% of area is occupied; the defined collection ratio is 66%. Rebuild each measure from the unit and rent ledgers.
