The U.S. Department of Justice, alongside multiple state attorneys general, has filed an antitrust lawsuit against RealPage, Inc., alleging that the property management software company facilitated collusion among landlords to inflate rental prices. The lawsuit claims that RealPage's algorithm allowed landlords to share sensitive pricing information, thereby undermining competition and enabling price-fixing, which adversely affects renters nationwide. Attorney General Merrick Garland emphasized that Americans should not have to pay higher rents due to such illegal practices. The lawsuit cites that RealPage's software monopolizes around 80% of the market for revenue management software in the multi-family rental sector. RealPage has denied the allegations, arguing that landlords retain the autonomy to set their own prices, and maintains that its software contributes positively to the rental ecosystem. This case reflects the Biden administration's broader push for aggressive antitrust enforcement across various industries.
