In other contexts there’s no problem with using proprietary data to set prices, so long as you don’t run afoul of insider trading regulations. Landlords also don’t have monopoly pricing power, they’re making tradeoffs. They can’t list their unit for a million per month or else it would never sell. They can’t list it for a dollar because they would lose money and be flooded with applicants. They’re trading between the highest price they can charge and the unit sitting vacant. AFAIK this is the value RealPage adds, it predicts what the optimal price would be. If it were instead doing something like predicting the market price is X, but telling landlords to set it at 1.3X and stick to their guns while units sit vacant and that eventually renters would have to give in, then it would be a price fixing scheme. Discovering the market price is not a price fixing scheme. Otherwise the NYSE is a price fixing scheme, far more than RealPage.
