There is no need to stress out prior to an Appraiser arriving. The Appraiser is there to calculate the value of the real estate, as long as the appraiser can safely move around the property everything will be fine. If you have pets, you will need to keep them under control. Please inform the Appraiser if you have recently performed renovations, improvements or your property has any known defects. Also please provide the Appraiser with any of the following that you may had available: Copy of your deed; Copy of a tax bill; Any property restrictions and HOA information.
