The Department of Justice announced a proposed consent decree with Willow Bridge Property Company as part of its ongoing enforcement action targeting alleged anticompetitive conduct in rental housing markets. The DOJ alleged that Willow Bridge and other landlords used competitors’ sensitive pricing information through algorithmic rent-setting tools and exchanged competitively sensitive rent and occupancy data.

The proposed decree — subject to court approval — would impose restrictions on Willow Bridge’s use of certain algorithmic pricing tools, competitor-data sharing, and participation in RealPage-hosted meetings where competitor information was exchanged.

The DOJ’s enforcement theory rests on the proposition that competing landlords who share sensitive pricing data — even indirectly, through a common algorithmic pricing platform — may be engaging in conduct that violates Section 1 of the Sherman Act. When competing landlords all input their sensitive occupancy and pricing data into a common platform (RealPage’s revenue management software), and the platform uses that pooled data to generate rent recommendations, the result is functionally equivalent to competitors sharing pricing information — a form of horizontal price coordination that antitrust law treats as per se illegal or subject to heightened scrutiny.

The DOJ’s theory does not require proof of an explicit agreement between landlords. The alleged anticompetitive effect arises from the structure of the information exchange itself.

• Algorithmic pricing tool restrictions: Willow Bridge restricted from using tools that incorporate competitors’ nonpublic data
• Competitor-data sharing restrictions: Prohibition on sharing sensitive pricing and occupancy data with competitors directly or through intermediaries
• RealPage-hosted competitor meetings: Restrictions on participation in meetings where competitor pricing information was exchanged
• Monitoring: If Willow Bridge uses third-party rent-pricing algorithms going forward, monitoring may be required

Revenue Management Software Property managers using algorithmic revenue management software — particularly platforms that aggregate competitor data — should conduct a careful antitrust review. The key question is whether the platform incorporates competitors’ nonpublic pricing and occupancy data.

Benchmarking Arrangements Industry benchmarking services that collect and aggregate rent and occupancy data from multiple landlords raise similar antitrust questions. The line between legitimate market research and anticompetitive information exchange depends on the specificity of the data and the use to which it is put.

Vendor Contracts Property managers should review contracts with revenue management software vendors for provisions requiring sharing of sensitive pricing and occupancy data.

Antitrust Training Internal communications about rents, occupancy strategy, and competitor pricing are potential evidence in antitrust investigations. Antitrust training for leasing and revenue management personnel is a practical risk-management step.

The Willow Bridge settlement is part of a larger DOJ enforcement action that includes a civil antitrust lawsuit against RealPage filed in August 2024. Several state attorneys general have filed parallel actions. Private class-action litigation by tenants is also pending in multiple jurisdictions.

The DOJ’s proposed settlement with Willow Bridge signals continued aggressive enforcement of antitrust law in rental housing markets. The core legal theory — that algorithmic pricing platforms aggregating competitor data can facilitate unlawful price coordination — has now been applied to consent decrees. Property managers, leasing software vendors, and real estate platforms should treat this as a compliance priority.
