One comparable in a grid required an adjustment on every line, totaling 35% gross. What does this signal about the appraisal?

Correct Answer

D) Investigate overall comparability and support; the percentage alone does not determine acceptability

A 35% gross total and many adjustment lines warrant evaluating overall comparability and evidentiary support. They do not establish a USPAP 25–30% limit or prove the sale unusable. Fannie Mae also sets no specific net/gross adjustment limitations; magnitude alone is not the acceptance test.

Answer Options
A
Reject it under a USPAP rule capping gross adjustments at 25%
B
Conclude that the subject is over-improved for its neighborhood
C
Assume each adjustment is wrong because adjustments were needed on many lines, and reject the sale from the grid
D
Investigate overall comparability and support; the percentage alone does not determine acceptability

Why This Is the Correct Answer

Option D is correct because a 35% gross total with an adjustment on each line calls for investigating overall comparability and the evidence behind the adjustments. Fannie Mae states that the number or amount of adjustments must not be the sole determinant of a comparable's acceptability. The percentage is a warning sign, not a pass-or-fail test.

Why the Other Options Are Wrong

Option A: Reject it under a USPAP rule capping gross adjustments at 25%

Option A is wrong because it cites a USPAP rule capping gross adjustments at 25%. USPAP contains no such percentage cap, and Fannie Mae also sets no specific net or gross adjustment limit.

Option B: Conclude that the subject is over-improved for its neighborhood

Option B is wrong because it concludes the subject is over-improved for its neighborhood. Large adjustments on one comparable show that sale differs from the subject; they do not by themselves establish over-improvement.

Option C: Assume each adjustment is wrong because adjustments were needed on many lines, and reject the sale from the grid

Option C is wrong because it assumes each adjustment is wrong because many lines needed adjusting and rejects the sale. Many adjustments call for checking their support, but they do not prove the adjustments are wrong or that the sale is unusable.

Big adjustments: investigate, don't eliminate

A high gross percentage is a flag to look closer at the sale and its support, not a rule that removes it from the grid.

How to use: Use this when a question attaches a fixed percentage limit to adjustments.

Exam Tip

Be wary of answers citing a USPAP percentage cap on adjustments; USPAP does not set one.

Common Mistakes to Avoid

  • -Believing USPAP caps gross adjustments at a set percentage
  • -Rejecting a comparable based on adjustment size alone
  • -Inferring over-improvement from one heavily adjusted comparable

Concept Deep Dive

Analysis

This question tests how to interpret a comparable with large gross adjustments. Many adjustments and a high gross total are signals to check the sale's overall comparability and the support for each adjustment. Neither USPAP nor Fannie Mae sets a fixed gross adjustment percentage that decides whether a comparable is acceptable.

Background Knowledge

Two common guides to comparability are the number of adjustments and the absolute gross adjustment for each sale. These guides help the appraiser decide how much weight to give a sale, but acceptability depends on overall comparability, data availability and the support for the adjustments.

Real-World Application

In a rural area with few sales, an appraiser's best available comparable needs a 35% gross adjustment. He keeps it, documents the market support for each adjustment, explains why better sales were not available and gives it appropriate weight.
