A Baltimore family says their home was undervalued by more than $250,000 because they’re Black. They have filed a housing discrimination lawsuit against the appraiser and mortgage lender. Their home was originally appraised at $472,000, and they were denied a refinancing loan. But after removing any indications that a Black family lived there, a second appraiser valued the home at $750,000. “It’s a concern, and it should be a concern for the entire appraisal industry, as well as mortgage lenders,” said James Park, executive director of the Appraisal Subcommittee.
