The complaint, filed earlier today by Attorney General Brian Schwalb, focuses on the multifamily landlords’ use of software from Texas-based firm RealPage, which suggests rental prices based on a pricing algorithm. Key to those models, according to the suit, is the data fed in from the landlords and the pressure RealPage puts on them to stick to the code-derived rental rates.

Yes, I’m sure those poor landlords fought against raising rent tooth and nail.
