HUD MAP Guide chapter 7: project income, rent rolls, vacancy, and collection lossEconomic occupancy describes revenue performance rather than whether a unit is physically occupied. A common property-level version divides rent realized for a period by the rent that could have been scheduled for the same available units and period. Because operators use different numerators and denominators, a useful report states whether it uses billed rent, collected rent, effective gross income, concessions, credit loss, and units unavailable for renovation.
Build the denominator from the same units and dates as the numerator. Then show vacancy, concessions, and unpaid occupied-unit charges separately instead of compressing every reduction into one unexplained percentage. Physical occupancy can remain high while economic occupancy falls because an occupied household has an open balance or because signed concessions reduce collections. The reverse can occur temporarily when prior-period payments enter the current cash total.
Consider four units with supportable scheduled rent of $6,000 for June. One unit is vacant for half the month, creating $750 of vacancy loss; an occupied tenant receives a documented $100 concession; and another $150 remains unpaid at the reporting cutoff. On a simple realized-rent basis, $5,000 divided by $6,000 produces 83.3% economic occupancy. The calculation becomes useful only when the report also exposes the three different causes of the $1,000 gap.
Red flags include changing the denominator when a unit performs poorly, counting collections from old balances as current-period rent without disclosure, or comparing cash-basis and accrual-style percentages as though they were identical. Lock the reporting policy, retain the source rent roll and ledger, and compare the component losses over time. Economic occupancy is a diagnostic summary, not evidence that one tenant or one leasing decision caused the result.
Formula and worked example
Economic occupancy equals a defined collectible or collected rent numerator divided by gross potential rent for the same period. Cash, recognized revenue, and charges net of concessions answer different questions.
Example: ten units have $15,000 potential rent. One is vacant, one has a $300 concession, and $600 is unpaid. Current rent collected of $12,600 is 84%; physical occupancy is 90%, isolating collection or concession effects.
Sensitivity and edge cases
Bridge changes into vacancy, concessions, delinquency, bad debt, and timing. Old-balance collections can raise the metric without improving the current period.
Choose the numerator before interpreting the percentage
“Economic occupancy” is not useful until the report names its numerator and denominator. A charge-based version can use current-period rent charges net of approved concessions divided by defined GPR. A revenue-based version can use recognized rental revenue. A collection-based version can use current-period rent collected, but must state how it treats old-balance receipts, pending payments, returns, subsidies, and cutoff timing. These versions answer different questions and should not be charted as one uninterrupted series.
Use the component bridge to find an operational owner
For a twelve-unit cohort with $24,000 of GPR, assume $2,000 of vacancy, $500 of approved concessions, and $1,000 of current-period rent still unpaid. Current-period collected rent is $20,500 and collection-based economic occupancy is about 85.4%. If eleven of twelve units are physically occupied, physical occupancy is about 91.7%. The 6.3 percentage-point gap is not one cause: the bridge shows concession and collection effects in addition to vacancy.
Assign each component to the relevant workflow: leasing owns vacant days and approved offers; receivables staff own open balance investigation; finance owns cutoff and formula consistency; asset management owns assumption and portfolio comparisons. Do not use the aggregate percentage to select a tenant for collection, judge leasing staff, or declare a property’s value without the underlying population and evidence.
Close criteria for a comparable metric
Lock the cohort and cutoff, reproduce GPR from the rent roll, reconcile concessions to approvals, tie collected amounts to the tenant and processor records, and isolate returned or pending payments. Compare like property types and policies; disclose unit outages, acquisitions, dispositions, subsidies, partial months, and rate-basis changes. If a policy changes, recast history or break the series visibly.
The metric can support trend detection, loss decomposition, and questions about leasing or collections. It does not prove cash availability, NOI, debt coverage, tenant collectibility, or legal authority for a collection action. Fannie Mae and HUD income bridges reinforce the need to separate vacancy, concessions, and collection effects, while the operator remains responsible for defining the metric used in its report.
