Construction loan appraisals are fundamentally different from appraisals of existing, stabilized properties, and the differences create specific risks for lenders who review construction appraisals without understanding those differences. A stabilized property appraisal assesses what the property is worth today based on observed income, market transactions, and replacement cost. A construction loan appraisal assesses what the property will be worth when it is complete and stabilized, a future state that does not yet exist and that requires the appraiser to make assumptions about construction costs, rents, vacancy, and market conditions at a point that may be 18 to 24 months in the future.
Those assumptions are where construction appraisal risk concentrates, and where lender review of appraisals must focus.
The As-Complete and As-Stabilized Values
Construction loan appraisals typically produce two values: the as-complete value (the estimated value of the completed project before lease-up) and the as-stabilized value (the estimated value after the project reaches stabilized occupancy at market rents). The as-stabilized value is the most important for construction lending because it determines the permanent loan amount that will repay the construction loan at takeout.
The as-complete value is useful for determining the construction loan amount relative to the completed value, a 75% loan-to-value ratio at as-complete value. The as-stabilized value is useful for assessing the permanent loan that will be available at stabilization.
Lenders should be aware that as-complete and as-stabilized values are both forward-looking estimates subject to the appraiser’s assumptions about construction costs, rents, vacancy, and capitalization rates at the time of completion. A construction loan appraisal completed in a rising market will project rents and capitalization rates that reflect the conditions at appraisal time; if market conditions soften during the 24-month construction period, the as-stabilized value may be lower than the appraisal projected, and the permanent loan at stabilization may be smaller than the construction loan underwriting assumed.
The Rent and Occupancy Assumptions
The most consequential assumptions in a construction loan appraisal are the projected rents and occupancy at stabilization. These assumptions drive the projected NOI, which drives the income approach to value, which in most multifamily appraisals is the primary valuation method.
Lenders should review the rent assumptions in a construction appraisal against the current market data for the specific submarket rather than accepting the appraiser’s conclusions without scrutiny. Common problems in rent assumption:
Comparable selection that doesn’t reflect the competitive set. An appraiser who selects comparable rentals from a broader market area rather than from the project’s specific submarket may produce rent conclusions that are above or below what the project will actually achieve. In a market with meaningful submarket variation, DFW, for example, where rents and vacancy vary significantly between submarkets, broad-area comparables produce less accurate rent conclusions than submarket-specific comparables.
Rent conclusions that don’t account for pipeline supply. An appraisal completed today that projects rents based on current market conditions may not adequately reflect the effect of new competitive supply that will deliver between now and the subject project’s stabilization. If the submarket’s supply pipeline includes competitive projects delivering before or concurrent with the subject, the rent conclusions should reflect the increased competition.
Aggressive lease-up assumptions. The as-stabilized value is based on an assumed stabilization timeline, how long after delivery will the project reach stabilized occupancy? An appraisal that assumes a 6-month lease-up when the market data suggests 12 to 18 months will produce a lower carrying cost assumption and a higher as-stabilized value than a more realistic lease-up timeline would produce.
Construction Cost Review in the Appraisal
Construction loan appraisals include a cost approach to value, an estimate of what the land plus the replacement cost of the improvements is worth. The cost approach requires the appraiser to estimate the construction cost of the proposed project.
Most appraisers are not construction cost specialists. They use published cost databases, Marshall & Swift, RSMeans, and local cost surveys to estimate construction cost per square foot. These database-derived estimates may be reasonably accurate for standard residential and light commercial construction in well-surveyed markets, but they frequently understate costs in high-cost markets (Seattle, Bellevue), overstate costs in lower-cost markets (El Paso, Albuquerque, secondary Texas cities), and fail to capture project-specific conditions (difficult site topography, specialty structural systems, complex MEP) that affect the actual cost of the specific project.
When the appraiser’s construction cost estimate is significantly below the GC’s bid or the owner’s construction budget, the discrepancy should be investigated before the loan closes, not accepted as evidence that the project is over budget. A $4.8 million GC contract on a project where the appraiser estimated $3.9 million of construction cost is not necessarily a budget problem; it may be an appraiser who underestimated local market costs. But the discrepancy should be explained, not ignored.
Capitalization Rate Assumptions
The income approach value in a multifamily construction appraisal is driven by the projected stabilized NOI divided by an estimated capitalization rate. Both the NOI projection and the capitalization rate involve judgment, and both can be wrong in ways that inflate the as-stabilized value.
Capitalization rates in construction appraisals should reflect the rates at which stabilized multifamily properties in the submarket are currently trading, not the rates at which they were trading 12 to 18 months ago. In a rising rate environment, capitalization rates for multifamily assets tend to expand as the cost of capital increases, which reduces values for a given NOI. An appraisal completed in a falling-cap-rate environment that projects those rates forward into a period of rising rates will overstate the as-stabilized value.
Lenders whose construction loan underwriting relies on as-stabilized values that include aggressive capitalization rate assumptions are carrying more value risk than the appraisal’s headline number suggests.
