The Software Quietly Setting Your Rent — RealPage Explained

Your landlord may not have decided your rent. A piece of software in Texas did — and it handed the same number to thousands of your landlord's competitors. That isn't a conspiracy theory. It's the spine of a lawsuit the U.S. Department of Justice filed in 2024, joined by 10 states, accusing one company of running an algorithmic pricing scheme that harms millions of American renters.

The thing you've already felt

You move to a new city, check three buildings — different owners, different neighborhoods, no connection to each other — and somehow they're all asking nearly the same rent. Then your lease renews and the number jumps the same week your friend two zip codes away gets the same jump. You assumed it was supply and demand. That assumption is exactly what makes this work.

A real market means rivals who don't talk, who each guess at a price and undercut one another to win you. That competition is what protects you. So ask the dangerous question: what if your landlord and the one across the street and eight more all stop guessing and ask the same source what to charge? They never meet, never call, never agree out loud. They just type their numbers into the same machine, and the machine tells each of them what to do.

The engine

The company is RealPage, a software firm in Texas; its product sells under names like YieldStar. Landlords feed it their private, non-public numbers — what they're actually charging, their lease terms, the data a rival is never supposed to see. The machine digests it and hands each landlord back a recommended price shaped by what their competitors are secretly doing.

Normally, sharing your pricing strategy with competitors is the textbook definition of collusion — the kind of thing that puts executives in prison. Two rivals can't legally sit in a diner and agree to both charge $2,000. Run that same agreement through software and it stops feeling like a crime. Everyone's just "following the data."

A former acting chair of the FTC put it best: replace the word algorithm with a guy named Bob. Is it okay for Bob to collect confidential pricing from everyone in a market and tell them all how to price? Obviously not. Laundering it through code doesn't change what it is.

In their own words

In 2022, the newsroom ProPublica cracked this open. The most damning line came from inside the industry: at a 2021 conference, after rents had spiked, a RealPage executive was asked what role the software played. His answer: "I think it's driving it, quite honestly." He added that very few landlords would dare raise rents double digits in a single month by hand. The software didn't follow the spike. By their own account, it was driving it.

And it doesn't just want rents high — it will tell you to keep apartments empty to get there. On a 2017 earnings call, RealPage described an operator with more than 40,000 units that made more money running at about 95% occupancy instead of 98%. Keep some units deliberately vacant, charge everyone else more, come out ahead.

Why it's hard to outlaw: hub and spoke

None of it works unless enough landlords near you obey the number — one holdout breaks the spell. So how many doors on your street are plugged in? In one Seattle zip code with around 9,000 apartments, ProPublica found the 10 biggest managers controlled 70% of them, and every one used RealPage. That's not 10 competitors. That's one cartel wearing 10 name tags.

Antitrust experts call this hub and spoke: the software is the hub, each landlord a spoke connected to the middle but never to each other. The old law was written to catch people in a room shaking hands. It struggles with a wheel, because there's no handshake to point to — just a lot of companies quietly agreeing with the same machine. The same shape now shows up in lawsuits over Las Vegas hotel pricing, chicken-processor data exchanges, and rival software like Yardi.

How it ended — and didn't

The law moved: San Francisco banned setting rent from non-public data in 2024, with Philadelphia and others following. Then in November 2025, the RealPage case settled — no fine, no admission. But look at the terms: the software can no longer use competitors' non-public data in real time; any data it learns from must be at least 12 months old; modeling can't get more specific than statewide; and a court-appointed monitor watches for years. Nobody banned the algorithm. They changed what it's allowed to see.

The discipline

The most powerful position in any system isn't the one giving orders — it's the one quietly setting the option everyone reaches for by reflex. Whoever sets the default owns the outcome. So the next time prices all move together — your rent, your renewal, the "fees" on something supposedly competitive — don't just ask who set the price. Ask who set the default, and ask what software is in the building. The settlement didn't kill this idea. It just aged the data by a year.
