The Uncertainty of Appraisals

Today I met an appraiser at one of my listings. He was an odd fellow, said very little and ask few questions. I offered to help him in any way I could but he refused. I talked up all of the wonderful points of the property; view, size of rooms, outdoor area, pool and guest house. He remained completley unemotional. When he was done I walked to his car and offered to email him comparible sales (comps), he said he would contact me if he felt he needed them. OH WHAT A FRUSTRATING process this is, relying on people you do not know, hoping they are educated about the area they are appraising, hoping they "get" the value of the property and waiting for the final result via the lender. I guess I understand how cautious these people need to be after the devastating damage done over the past couple of years based on inaccurate and trumped up appraisals. I uncomfortable with the unknown.
