If the information presented by the owner, or a material change in the character or condition of the property, indicates the need for new appraisal information, or if a significant delay has occurred since the time of the appraisal(s) of the property, the Agency shall have the appraisal(s) updated or obtain a new appraisal(s). If the latest appraisal information indicates that a change in the purchase offer is warranted, the Agency shall promptly reestablish just compensation and offer that amount to the owner in writing.
