Fair housing groups have filed a lawsuit over a rule change by the Trump administration that they allege reverses decades of lending protections and opens the door to discrimination against Black people, Latinos and other minorities.

But Redfin’s minimum price and other policies have had the opposite effect, according to the National Fair Housing Alliance, a Washington, D.C.-based nonprofit dedicated to eliminating housing discrimination, and nine of its member organizations. Under the minimum price policy, Redfin doesn't offer its full services unless homes are listed for certain prices, which vary by market. In adjacent, predominantly white DuPage County, however, the minimum price was just $275,000. Further, it alleged, Redfin sometimes failed to provide services even when a home's price topped the minimum. The lawsuit asks the court to block any Redfin policies found to violate federal fair housing law and seeks punitive damages.
