FAQ
What is an appraisal hike percentage?
An appraisal hike percentage is the percentage increase between an old appraisal value and a new appraisal value. It shows how much the value rose compared with the original appraisal, not just the dollar increase.
Can the appraisal hike percentage be negative?
Yes. If the new appraisal is lower than the old appraisal, the result is negative. For example, if an appraisal falls from $300,000 to $270,000, the hike percentage is -10%. In that case, it is better described as a decrease rather than a hike.
Why can’t the old appraisal be zero?
The old appraisal cannot be zero when calculating the hike percentage because the formula divides by the old appraisal. Division by zero is not valid, so you need a nonzero old appraisal value.
