Which of the following actions is prohibited for an appraiser?

An appraiser is prohibited from buying and selling salvage as a result of appraisal services because this activity can create a conflict of interest. An appraiser's primary responsibility is to provide an impartial and objective valuation of a property without any personal stake in the transaction. Engaging in buying or selling salvage based on information or insights gained from performing appraisal services undermines the integrity of the appraisal process and raises ethical concerns. It is crucial for appraisers to maintain independence and avoid situations that could influence their judgment or compromise the credibility of their appraisals.

The other actions listed, such as conducting inspections on commercial properties, providing consultations for appraisal methods, and charging for written appraisals, are typically permitted within the scope of professional appraisal practices, provided they are carried out ethically and according to established guidelines.
