A new US Department of Justice civil lawsuit puts RealPage at the center of a major question for the rental housing market: when does pricing software become a tool for coordination rather than competition?
The case focuses on RealPage, a Texas-based company that sells commercial revenue management software to landlords. The DOJ alleges that the company’s algorithm uses sensitive rental data to recommend, and in many cases help set, apartment prices in ways that reduce competition and push rents higher.
What the DOJ says RealPage does
RealPage’s software is designed to help landlords manage rental revenue. According to the DOJ, landlords feed rental rates and lease terms into the system. The RealPage algorithm then produces suggested apartment prices.
The government’s allegation is that this process does more than assist individual landlords. The DOJ says the system enables coordination across landlords that would otherwise be competing with one another. In that view, an algorithm becomes the channel through which sensitive information is gathered, processed, and turned into pricing guidance.
Deputy attorney general Lisa Monaco framed the issue as a modern version of an old antitrust problem. She said RealPage found a way to violate a century-old law through systematic coordination of rental housing prices by using sensitive data and an artificial intelligence-powered algorithm.
The DOJ also says the software tends to raise prices more than lower them. In the department’s words, “RealPage’s software tends to maximize price increases, minimize price decreases, and maximize landlords’ pricing power.”
Why the company’s reach matters
The DOJ says RealPage controls 80 percent of the market for software of its kind. The same software category is used to set prices for around 3 million units across the country, according to the department.
That scale is central to the case. A pricing tool used by a small number of landlords may have limited influence. A tool used broadly across a market can become much more consequential, especially if the government can show that it changes how landlords make pricing decisions.
RealPage already faces multiple lawsuits. The source article identifies cases from Arizona and Washington, DC. In Washington, DC, RealPage software is allegedly used to price more than 90 percent of units in large apartment buildings.
The company’s algorithmic pricing drew broader public attention after a 2022 ProPublica investigation described how its YieldStar software works. The DOJ lawsuit is a further escalation, and it was joined by the attorneys general of eight states.
From recommendation to pricing control
A key part of the DOJ’s argument is that RealPage’s software is not merely advisory in all cases. The department alleges that RealPage actively polices whether landlords follow its pricing recommendations.
US attorney general Merrick Garland said many landlords use an “auto-accept” setting. According to Garland, that setting effectively allows RealPage to determine the price a renter will pay.
That detail matters because it shifts the focus from software that informs a decision to software that can take over the decision. If landlords outsource pricing choices to the same system, the DOJ’s theory is that competition can be weakened even without landlords directly sitting together to agree on rents.
The complaint also alleges that RealPage created a “self-reinforcing feedback loop” through its data intake and pricing recommendation structure. The DOJ says this structure supports an alleged monopoly in the apartment revenue management software industry and leaves rule-following competitors at a disadvantage.
RealPage denies the allegations
RealPage has repeatedly denied allegations of antitrust violations. The company has published a six-page digital pamphlet presenting what it calls “the Real Story” about its products, along with an FAQ page on a public policy website.
One section of that site says, “RealPage revenue management software benefits both housing providers and residents.” The company also says attacks on the industry’s revenue management are based on demonstrably false information.
Jennifer Bowcock, senior vice president of communications and creative at RealPage, said in an emailed statement that the company was disappointed by the DOJ’s decision to sue. She described the lawsuit as an attempt to scapegoat pro-competitive technology that has been used responsibly for years.
Bowcock also said, “RealPage’s revenue management software is purposely built to be legally compliant.” The company says it has worked constructively with the DOJ on these antitrust matters.
Why this case could shape algorithmic antitrust
The lawsuit is notable not only because it involves rental housing, but because of how the DOJ describes the alleged violation. Officials speaking on background said this is the first civil action in which the algorithm itself was effectively the means of the violation.
The government has previously filed criminal charges against an Amazon seller for algorithm-enabled price-fixing. This RealPage case, however, is described by DOJ officials as the first major algorithmic collusion case of its kind.
Monaco summarized the department’s position directly: “Algorithms don’t exist in a law-free zone.” She added, “Training a machine to break the law is still breaking the law.”
The Justice Department has spent the past several years adding technologists and data scientists, giving officials more ability to “interrogate the code.” DOJ officials suggested that this case may not be the last time algorithmic coordination becomes an antitrust issue.
For renters, the immediate issue is straightforward: the DOJ alleges that software used by landlords helped make apartment prices move upward and limited competitive pressure. For the broader market, the case asks whether a shared pricing algorithm can become the digital equivalent of coordination among competitors.
