The Yardi Revenue IQ lawsuit: what Yardi customers should know

Quick answer

On October 13, 2026, Judge Robert Lasnik of the federal court in Seattle denied Yardi's motion for summary judgment in Duffy v. Yardi Systems, a class action that alleges Yardi's Revenue IQ software helped landlords exchange nonpublic pricing information. The case now moves to further discovery, which includes landlords' records. Yardi denies wrongdoing. In October 2025, a California state court granted Yardi summary judgment in a separate Revenue IQ case, Mach v. Yardi.

The allegations. According to Multifamily Dive, the plaintiffs allege that Yardi exchanged competitively sensitive, nonpublic information with clients through Revenue IQ. The suit also alleges that defendants discussed pricing with competitors through market surveys.

Yardi's position. Yardi denies wrongdoing. Yardi says its software never uses confidential competitor data in rent recommendations. It says the software relies on each client's own property data and public housing market information. A Yardi spokesperson told Multifamily Dive, "There is nothing illegal about Yardi's revenue management product."

The October 2026 ruling. Judge Lasnik denied summary judgment, so the case moves forward. He found that the first, Yardi-focused phase of discovery did not make broader discovery unnecessary. The order states that it expresses no view on the ultimate merits of Yardi's arguments. The court will now develop the record, including landlords' knowledge, communications, and conduct. Remaining claims will then be decided on summary judgment.

The California case. In Mach v. Yardi, the Alameda County court found that Revenue IQ did not violate California's antitrust and unfair competition laws. According to Multifamily Dive, the court found that the software does not use one client's confidential pricing information to recommend prices for another.

What it means for Yardi customers

Revenue IQ users. The case concerns Revenue IQ. According to Multifamily Dive, the next phase of discovery includes landlords' records. If you receive a request for records, involve your counsel.
Voyager and Breeze users who do not use Revenue IQ. The lawsuit concerns the revenue management product, not Yardi's accounting or operations software.
Contract terms and pricing. Yardi Voyager is quote only. Vendr reports directional ranges, such as $50,000 to $150,000 per year for 1,000 to 5,000 units. These are third-party estimates, not Yardi prices. Read your agreement for renewal and notice dates.
Data access and export. Yardi does not publish data export terms for Voyager. Ask in writing how your data is returned at termination.
Product direction. Yardi announced Virtuoso AI agents for every multifamily role in June 2026. In September 2025, Yardi announced that Rob Teel would succeed founder Anant Yardi as CEO in January 2026, according to Wikipedia.
Support. Capterra reviewers praise Yardi Voyager's reporting and breadth. G2 reviewers report a steep learning curve. Some Capterra reviewers report a dated interface and inconsistent support.

What to do now

List the properties that use Revenue IQ and the date each one started.
Find the renewal dates for Voyager and for Revenue IQ.
Keep records of how rents are set: the recommended rent, the approved rent, and who approved it.
Export the rent roll, resident ledgers, owner balances, security deposits, and lease documents. Store them outside Yardi.
Ask Yardi these questions in writing:
- What data does Revenue IQ use for my recommendations?
- Can I export a history of recommendations and accepted rents?
- In what format do I receive my data at termination, and at what cost?
- Is there a cap on my price increase at renewal?
Ask your counsel to review your pricing practices.

Where to go next
