Millions of rents across the United States may now be set using one company’s algorithmic software, according to a federal lawsuit and a Washington Post analysis.

RealPage, a property management software company, uses a trove of data to suggest rental prices to landlords. The software has been widely adopted by property managers — and is now facing strenuous legal pushback.

Over the past three years, the company has been sued by the federal government, which alleged in August that it unlawfully decreases competition among landlords; by several individuals; and by the governments of Arizona and D.C., which have accused RealPage and dozens of property management companies of colluding to raise prices.

On Tuesday, the Justice Department expanded its suit to sue six large landlords, which it says operate in 43 states and D.C.

To assess how widespread use of RealPage’s rent software may be, The Post identified 3.1 million market-rate rental units managed by companies named in the lawsuits. That analysis found 10 counties where more than 1 in 3 multifamily units are managed by a property company allegedly using a rent-setting program from RealPage.

Access to competitors’ rental data is at the center of the legal battles against RealPage. The Justice Department alleges landlords provide private rental data to RealPage, which uses its technology to train the company’s pricing algorithm and make suggestions to landlords on what to charge.

“These recommendations are based on the sensitive information of their rivals,” the suit states.

One landlord using RealPage revenue management technology started increasing rents within a week of using the program, raising prices more than 25 percent in 11 months, according to the suit.

In a video on its site, RealPage said it helps properties “exceed the market” by 2 to 5 percent in revenue. But the company has said that its software — the latest version of which is called AI Revenue Management, or AIRM — does not let clients see competitors’ specific rents and that its “price recommendations are based primarily on the subject property’s own internal supply and demand data.”

RealPage said about 600 customers use its revenue management software for more than 4.5 million residential units. RealPage declined to provide their locations, citing customer confidentiality, and said The Post’s map would be “highly inaccurate” without that confidential data.

Among property management companies named in the lawsuits, some have stopped using the software, RealPage said, while others do not use it at all their properties. In court filings, the defendant property management companies have broadly denied allegations of collusion.

The lawsuits indicate that use of RealPage’s software is widespread: They list more than 50 property management companies, including some of the largest in the country, as customers of at least one of three RealPage rent-recommending programs.

Nationwide, the named companies manage at least 12 percent of all multifamily housing units, a Post analysis found, often concentrated in areas that have seen recent building booms. Of units built since 2020, more than 70 percent are managed by alleged clients of RealPage’s rent-setting software.

In the region around D.C., the first government to file suit against RealPage, about 24 percent of multifamily units are managed by companies alleged to have used RealPage’s rent software.

These buildings are often new high-rises chock-full of amenities. In just one square mile of Washington’s Navy Yard neighborhood, for example, where an onslaught of development has sent rents soaring, 22 buildings are managed by companies named in the suits, according to The Post’s analysis.

Rent prices in D.C. increased 1.6 percent from June 2023 to June 2024, and are up more than 10 percent from their pre-pandemic levels.

In its lawsuit, D.C. alleges that RealPage and property management companies used the software to “inflate rents for tens of thousands of apartments across the District, causing District renters to pay millions of dollars they would not have.”

In one case, the D.C. lawsuit alleges, RealPage sent a monthly report in 2022 to property management company WC Smith, stating the company was able to increase revenue per unit by 4.6 percent.



RealPage has disputed that its technology is designed to raise prices, saying it is intended to adjust prices based on supply and demand, and it recommends both price increases and decreases. RealPage also argued that rent increases have been lower in the areas of Maryland and DC where use of its software is more prevalent.
