Three lawsuits filed in July allege property management firms used software to collect non-public data and coordinate rents, violating the city ordinance. According to a Technical.ly report, Philadelphia's law prohibits price coordination by collecting non-public rental data and using it to suggest rents, lease terms, or occupancy levels. Yardi's Yardi Matrix allegedly sources data from internal pricing surveys and property management software, according to Technical.ly. RealPage, founded in 1998, sells software to property owners and property management companies. The company's platform features tools to manage lease agreements, resident services, finances, and other aspects of rental property management.
