An appraisal adjustment accounts for meaningful differences between a comparable sale and the subject property.
An appraisal adjustment is a change used in an appraisal analysis to account for meaningful differences between a comparable sale and the subject property.
Appraisal adjustments matter because no comparable sale is usually identical to the Subject Property. A comp may have a larger lot, better condition, fewer bedrooms, a different view, or a different sale date. Adjustments help the appraiser translate those differences into a more useful comparison.
They also matter because borrowers often assume the highest or closest sale should control the value. In reality, a sale may need adjustments before it can support the Appraised Value in a mortgage file.
Borrowers usually see appraisal adjustments after the report is complete, especially if they are reviewing why a value came in lower or higher than expected.
The term becomes practical during an Appraisal Review or a Reconsideration of Value request, because the dispute often turns on whether the selected comps, support for the adjustments, and overall adjustment pattern make sense.
| Difference being adjusted | Why it can matter |
|---|---|
| Gross Living Area | Larger or smaller homes may not support the same value directly |
| Condition Adjustment | Renovated and worn properties may need different treatment |
| Location Adjustment | A busy road, view, lot size, or neighborhood boundary can affect comparison |
| Time Adjustment | Older sales may need context if the market has shifted |
| Paired Sales Analysis | Can help support the market effect of a difference |
| Net Adjustment and Gross Adjustment | Help readers judge the total adjustment pattern |
| Adjusted Sale Price | The comp’s indicated value after adjustments are applied |
An appraiser compares the subject property with a nearby sale that has a renovated kitchen and an extra bathroom. The sale is useful, but it is not identical. The appraiser may apply adjustments so the sale better reflects what it would indicate if it were more like the subject property.
Appraisal adjustment differs from Comparable Sales (Comps) because comps are the sales being compared, while adjustments are the changes made to account for differences.
It also differs from the Sales Comparison Approach. The sales comparison approach is the broader valuation method; adjustments are one tool used inside that method.
It differs from Paired Sales Analysis because paired sales analysis is one way to support an adjustment, while the adjustment is the line-item change applied in the grid.
It differs from Appraisal Gap because adjustments are part of the valuation analysis, while an appraisal gap is the financing problem that can result if the supported value is below the agreed price.
