The appraiser must fill in all the information to the extent it is available and reliable and must provide analysis as indicated below. If any required data is unavailable or is considered unreliable, the appraiser must provide an explanation.

Sales and listings must be properties that compete with the subject property, determined by applying the criteria that would be used by a prospective buyer of the subject property. The appraiser must explain any anomalies in the data, such as seasonal markets, new construction, foreclosures, etc. Inventory Analysis Prior 7–12 Months Prior 4–6 Months Current – 3 Months
How much clearer can they get? They want market condition adjustments ( time adjustments) from 12 months to present, NOT 2 years back or 3 years back to present.

Comment in narrative about larger area non competing sales activity, or prior year market condition changes, but for trend section and market condition adjustments, they want relevant to subject properties and past year activity to avoid misleading results from basing trends on dis similar properties or dated activity.
