Under the Appraiser Independence Requirements (AIR), appraisers are obligated to perform their duties free from outside influence or coercion. Asking the appraiser to substantiate a value is permissible because it falls within the scope of ensuring an accurate and credible appraisal. However, it is not permissible to pressure the appraiser into achieving a target value (A) or to withhold payment (B) for unfavorable valuations.

Direct communication between the loan officer and the appraiser (D) may be restricted or controlled to prevent undue influence.
