Appraisers and homeowners tend to be at odds with each other, but they're almost hand-in-hand now. In the Quicken Loans Home Price Perception Index (HPPI), a monthly report by retail mortgage lender Quicken Loans, it shows that the opinions of homeowners and appraisers are becoming more similar on a national scale. Locally, appraisers' opinions of home values are nearly 1.8 percent more than those of Washington D.C. residents. This time last year, the difference in opinions was by 2.2 percent. With Washington's median home price at roughly $389,000, the gap in opinions translates to a difference of about $7,000.
