HOw long does it take after the lender ordered an Appraisal for an FHA mortgage to have an appraiser on site? And does the buyer to seller get contacted prior to the appraisal ?

The physical inspection of the property will take approximately fifteen minutes to several hours. After the initial inspection is over, the appraiser spends time touring through the neighborhood or area in order to search for comparable sales that have sold within the last six months to a year. When the field work is finished, the appraiser completes the report at his office. This report will take few hours to complete.
