Appraisal technique that uses comparable sales above and below the subject property's key characteristics.
Bracketing is an appraisal technique that uses comparable sales above and below the subject property’s key characteristics.
Bracketing matters because it can make a value conclusion easier to understand. If comparable sales surround the subject property by size, condition, quality, or value indication, the final conclusion may look better supported than if every comp sits on only one side.
It also matters in mortgage review because bracketing can help answer a common borrower question: “Why did the value land here instead of at the highest sale?” A well-supported appraisal often shows how the subject fits within a range of evidence rather than leaning on a single preferred sale.
Bracketing is useful support, but it is not a substitute for good comp selection or market-supported adjustments. Available sales may not bracket every characteristic, especially for unusual properties or thin markets. The report should explain the evidence rather than force weak sales into the analysis only to create a bracket.
Borrowers encounter bracketing indirectly inside the comparable-sales grid and sometimes during Appraisal Review.
The term becomes practical when the lender, reviewer, or borrower is asking whether the Comparable Sales (Comps) reasonably support the Appraised Value.
Borrowers may see bracketing in the raw characteristics, such as one comp larger and one smaller, or in the adjusted value indications. These are related but different patterns. A property can be bracketed by size while the adjusted values cluster closely, or the physical characteristics can be similar while the adjusted indications span a wider range.
| Characteristic | What bracketing may show |
|---|---|
| Living area | One comp smaller and one comp larger than the subject |
| Condition | Sales with slightly inferior and superior condition |
| Value indication | Adjusted values that surround the final conclusion |
| Lot or feature differences | Evidence on both sides of a meaningful feature |
The appraiser still evaluates the quality of each sale. One superior and one inferior comp do not automatically receive equal weight, and the final value is not automatically the midpoint between them.
Bracketing one characteristic does not prove that every other comparison is strong. A larger comp may also be newer, better located, and more updated, while a smaller comp may be the subject’s closest overall match. The appraiser must analyze those differences rather than treating the size bracket as complete support.
An appraisal also does not fail merely because available sales cannot bracket every feature. Unique homes and thin markets may offer no credible sale on one side of a characteristic. In that situation, using the best available evidence with supported adjustments and clear explanation is more defensible than importing a weak sale solely to complete a visual bracket.
A subject property has 1,900 square feet. The appraisal includes one similar sale at 1,750 square feet and another at 2,050 square feet, along with supported living-area adjustments. Those sales bracket the subject’s size. If the smaller sale is otherwise a much better location and condition match, however, the appraiser may still give it more weight instead of averaging the two indications.
Bracketing differs from Comparable Sale Selection because selection is the broader choice of relevant sales, while bracketing is a way the selected sales can surround the subject’s characteristics.
It differs from Appraisal Adjustment because adjustment changes a comp for differences; bracketing describes the pattern of evidence around the subject property.
It also differs from Value Reconciliation because reconciliation is the final weighing of evidence, while bracketing is one support pattern within that evidence.
Bracketing differs from Paired Sales Analysis. Bracketing places the subject within a range of comparable evidence; paired sales analysis tries to isolate the market contribution of a particular difference.
