The gap between homeowner and appraiser opinions of home values has nearly doubled since May, according to mortgage lender Quicken Loans. Quicken Loans publishes a “Home Price Perception Index” which it states represents the difference between appraisers’ and homeowners’ opinions of home values. The index compares the estimate that the homeowner supplies on the mortgage application to the appraisal that is performed later in the mortgage process. “Many homeowners around the country are seeing the national headlines about home value increases and they are optimistic about their equity increasing,” said Quicken Loans Chief Economist Bob Walters. “While some areas are seeing the same level of home appreciation, or even more, there are also some areas that have slower home value increases. This can lead to homeowners and appraisers not quite seeing eye-to-eye.”
