Physical vs Economic Occupancy

Real Assets & Fractional Structures

Definition

Physical occupancy is the share of a property's units, square feet or acres that are occupied at a point in time or on average over a period. Economic occupancy is the share of gross potential rent the property actually earns: rent collected (or billed and collectible) divided by what it would earn fully occupied at full scheduled rent. The two diverge whenever occupied space does not pay full rent: free-rent concessions, tenants in arrears or eviction, below-market leases, employee or model units, and units occupied but not yet billed. A property can report 95% physical occupancy and 90% economic occupancy in the same year. Economic occupancy is the one that drives income, which is why it is the better test of a property's performance and the figure owners tend not to publish.

Why it matters

Occupancy is the most quoted operating statistic in property marketing because it is easy to measure and usually high. It answers whether space is filled, not whether it pays. In a soft market, owners keep buildings full with concessions; in a stressed one, tenants stay but stop paying; and a single-family rental can be occupied by a tenant in a months-long eviction. Each keeps physical occupancy high while income falls. For investors reading a fractional or fund property report, the useful question is how much of potential rent was actually earned, and that requires the rent figures, not the occupancy figure.

Common misconceptions

  • •Occupied is not paying. Concessions, arrears and evictions all sit inside physical occupancy.
  • •A point-in-time occupancy figure is not the year's average. Quarter-end snapshots can hide turnover.
  • •High occupancy can be bought. Concessions fill units at the cost of rent.
  • •Farmland's near-full occupancy does not guarantee income. Variable rent and collection still matter.
  • •Unreported occupancy is not neutral. If a platform discloses rent but not leasing, ask why.

Technical details

Formulas

Physical occupancy = occupied units (or square feet, or acres) / total units, at a date or averaged over a period.

Economic occupancy = (gross potential rent minus vacancy loss minus concessions minus collection loss) / gross potential rent.

Some operators also subtract loss to lease (below-market in-place rents) to measure against market potential.

Worked example: same building, two measures

20 units, $1,500 scheduled rent, gross potential rent $360,000 a year.

Average physical occupancy 94% (vacancy loss $21,600).

Concessions $6,000; collection loss $5,400.

Economic occupancy = $327,000 / $360,000 = 90.8%.

The 3.2-point gap is $11,400 of rent the occupancy figure does not show.

How investors apply the term

Investors usually apply this term by tying the definition back to the controlling documents and then asking which cash flows, rights, restrictions, or valuation assumptions it changes. A useful review looks at the term alongside fees, leverage, liquidity, reporting frequency, and manager discretion rather than treating it as a standalone concept.

The practical diligence test is simple: identify who benefits if the assumption is wrong, who has control when conditions change, and what evidence the investor receives after closing. Terms that cannot be reconciled to documents, cash movements, and monitoring data should be treated as marketing shorthand until proven otherwise.

Frequently asked questions

Can a fully occupied property still have weak rental income?
Yes. Every unit can be occupied while some tenants pay discounted rent under concessions, some are behind on payments or being evicted, and some leases are below market. Physical occupancy would be 100% while economic occupancy, the rent actually earned against full potential rent, could be far lower.
How is economic occupancy calculated?
Divide the rent actually earned in a period (gross potential rent minus vacancy loss, concessions and collection losses) by gross potential rent. For a 20-unit building with $360,000 of potential rent, $21,600 of vacancy loss, $6,000 of concessions and $5,400 of bad debt, economic occupancy is $327,000 / $360,000 = 90.8%, while average physical occupancy was 94%.
Which figure do platforms report?
Usually physical occupancy, if any. AltStreet's RealtyMogul review records 92% occupancy on its joint-venture equity and 74% on one office portfolio; Amber Farmland reported no vacancies at March 31, 2026; Ark7's series Form 1-Ks give rent and expenses but not leasing status. Economic occupancy usually has to be reconstructed from rent and collection figures.
What does occupancy mean for farmland?
Physical occupancy is usually near 100%: Farmland Partners says it believes quality farmland has a near-zero vacancy rate. Economic occupancy then depends on whether rent is collected, which advance rent payments protect, and on variable rent, which falls in bad crop years.
