The underwriter may request a reconsideration of value when the appraiser did not consider information that was relevant on the effective date of the appraisal. The underwriter must provide the appraiser with all relevant data that is necessary for a reconsideration of value.
The appraiser may charge an additional fee if the relevant data was not available on the effective date of the appraisal. If the unavailability of data is not the fault of the borrower, the borrower must not be held responsible for the additional costs. The effective date of the appraisal is the date the appraiser inspected the property.
