Last summer, Nathan Connolly and his wife, Shani Mott, welcomed an appraiser into their house in Baltimore, hoping to take advantage of historically low interest rates and refinance their mortgage.

But 20/20 Valuations, a Maryland appraisal company, put the home’s value at $472,000, and in turn, loanDepot, a mortgage lender, denied the couple a refinance loan.

Dr. Connolly said he knew why: He, his wife and three children, aged 15, 12 and 9, are Black. A professor of history at Johns Hopkins University, Dr. Connolly is an expert on redlining and the legacy of white supremacy in American cities, and much of his research focuses on the role of race in the housing market.

Months after that first appraisal, the couple applied for another refinance loan, removed family photos and had a white male colleague — another Johns Hopkins professor — stand in for them. The second appraiser valued the house at $750,000.

This week, Dr. Connolly and Dr. Mott sued loanDepot, which is based in Foothill Ranch, Calif., as well as 20/20 Valuations and Shane Lanham, the owner of 20/20 Valuations. Mr. Lanham is the appraiser who conducted the first appraisal.
