Sounds like the appraiser sucks. Or your neighborhood sucks.
Of course, you, the homeowner, can directly work with the appraiser, and should.
Me, when I want something appraised, I give the apraiser detailed information regarding comp sales, detailed property descrition, and generally make his or her job easier, and thus get get the result I intend, be it a high or low appraisal.
But then I am not a liberal loser who blames others for my lot in life.
