It is nearing the deadline for protest and the appraised value of my home went up $10k from $100,500 to $110,500 for an increase of 9.96%. I compared that to the 3 homes that were used for sales comparisons on the official value of appraisal report when purchasing my home in 2010, the average percentage increase of those 3 homes were 15.01%. The average percentage increase in appraised value for the homes along my street was 11.61% for the 12 homes I decided to look into. In short, just about every home in my area is going up by at least 10%, I made the mistake of procrastinating on developing a plan to protest the value of my home, but after little research I am beginning to think my efforts would prove to be ineffective against the Appraisal Review Board. Anyone have experience in this matter?
