Your listing agent can meet the appraiser at the time of the appointment at your home. In person, your agent can point out the upgrades and discuss nearby comps with the appraiser. I present the appraiser with the comps and the notes, so that the appraiser can take my material back to his office to consider. Most good appraisers understand and put a monetary value on upgrades, high-end finishes, and other aspects of your home that increase its value. Good luck...it will go well.
