Stabilized occupancy is the long-run average occupancy rate that a property is expected to sustain under normal market conditions after lease-up is complete. It represents an equilibrium assumption, not a peak occupancy achieved in a single favorable quarter and not a trough occupancy produced by a major tenant vacancy, but the level that a reasonably well-managed building in a functioning market can maintain over time.
Appraisers and underwriters use stabilized occupancy rather than current actual occupancy when valuing properties that are in the process of lease-up, have recently experienced a significant tenant departure, or are operating in a temporarily disrupted market.
Stabilized occupancy differs from physical occupancy in a way that matters for cash flow modeling. Physical occupancy is the percentage of rentable area currently leased; economic occupancy is the percentage of potential rent actually being collected (a tenant in occupancy but not paying rent, as during a free rent period, is physically occupied but economically vacant).
Stabilized occupancy is forward-looking: it represents the expected long-run equilibrium, not the current moment, and it drives the market vacancy allowance applied in the pro forma: if the market is 10% vacant and the subject property's stabilized occupancy is expected to be 92%, the model applies an 8% vacancy deduction to gross potential rent to arrive at effective gross income.
The gap between current occupancy and stabilized occupancy is the lease-up discount in CRE valuation. An appraiser valuing a newly completed office building at 40% occupancy uses the stabilized occupancy (say, 90%) as the income basis for the going-in cap rate valuation, then deducts a lease-up discount (the present value of the cash flows foregone during the expected lease-up period) to arrive at the as-is value.
This discount can be substantial: if lease-up is expected to take 36 months, the as-is value will be significantly below the stabilized value, and the difference represents the lease-up risk that a buyer acquires when purchasing the property in its current condition.
Market-level stabilized occupancy rates vary by asset class, submarket, and cycle position. Multifamily assets in supply-constrained urban markets may carry stabilized occupancy assumptions of 95-97%; suburban office markets with persistent oversupply may use 80-85%.
Appraisers derive stabilized occupancy from comparable property surveys, market reports from major brokerage houses, and long-term vacancy trend data; the assumption must be supportable by observable market evidence rather than derived from the subject property's historical peak performance alone. A stabilized occupancy assumption that exceeds what comparable properties sustain in the same submarket is a red flag in any underwriting review.
During lease-up a newly built or repositioned property runs below its long-run occupancy while it signs tenants. Stabilized occupancy is the level it is expected to reach and hold once that lease-up is complete, so underwriters value the asset on the stabilized figure and then subtract a lease-up discount to reach as-is value.
That discount is the present value of the rent and expense recovery foregone while the building fills. The longer the projected absorption period, the wider the gap between as-is and stabilized value, and the larger the lease-up risk a buyer assumes when acquiring the property in its current condition.
Stabilized net operating income is the NOI the property produces at stabilized occupancy, net of a market vacancy and credit-loss allowance. It is the income figure appraisers capitalize at the going-in cap rate and the figure lenders size debt against, because it reflects normalized operations rather than a temporary vacancy or an unusually full building.
Because the assumption drives value directly, it must be supportable from observable evidence: comparable-property surveys, brokerage market reports, and long-term submarket vacancy trends. A stabilized occupancy that exceeds what comparable properties actually sustain in the same submarket is a standard red flag in an underwriting or appraisal review.
Stabilized occupancy is the occupancy rate a property is expected to sustain over the long run under normal market conditions after lease-up, usually below 100% by a market vacancy factor. Underwriters use it instead of current actual occupancy to value a property on normalized operations.
It varies by asset class, submarket, and cycle. Supply-constrained multifamily may stabilize around 95% to 97%, while oversupplied suburban office may stabilize at 80% to 85%. The rate should be supported by comparable-property surveys, not the subject property's own historical peak.
Lease-up is the interim period while a new or repositioned property fills toward its long-run level; stabilized occupancy is the level it holds once lease-up is done. A property is underwritten on its stabilized occupancy, with a lease-up discount deducted to reach as-is value.
Stabilized occupancy sets the vacancy allowance deducted from gross potential rent. At 92% stabilized occupancy the model deducts 8% for vacancy to reach effective gross income, then subtracts operating expenses to get stabilized NOI, the income appraisers capitalize at the going-in cap rate.
No. Physical occupancy is the share of space currently leased at a point in time. Stabilized occupancy is a forward-looking long-run equilibrium. A space can be physically occupied but economically vacant, for example during a free-rent period when the tenant is in place but not yet paying rent.
