RealPage, a Texas-based company behind a software called YieldStar, is facing a Department of Justice investigation. The company has been accused of facilitating landlord collusion through its software and driving up rental prices beyond market values.

In October, ProPublica, a nonprofit, investigative news outlet, reported on RealPage and its software. The investigation found that the company’s software does seem to push rents higher than market prices. In one Seattle neighborhood, the outlet found that 70% of apartments were managed by landlords that used the software. Heather Vogell is a reporter with ProPublica and has reported on RealPage. She joins us with details of the outlet’s findings.
