The U.S. Department of Justice (DOJ) has filed a lawsuit against Rocket Companies, alleging that they discriminated against a Black homeowner by undervaluing her home in a mortgage refinancing appraisal. The lawsuit also claims Rocket Mortgage interfered with the homeowner’s rights by canceling her refinancing application after she reported the discrimination. The DOJ alleges the appraisal company used sales data from neighborhoods with larger Black populations to undervalue the home.
