Quite the contrary. In my younger days, I could not afford an apartment. So what did I do? I got together with a friend who could not afford an apartment, either, and we shared an apartment.
I've also rented a house with multiple roommates to bring the cost down.
It is a natural feedback loop of an algorithm like this. If it is designed to look at the properties around your location, and you try to get the most money for your property, over time those prices will go up as the algorithm tests what people are willing to pay for a given unit/building/location.
You could argue that this may have already happened with humans, but at a different pace and the algorithm is literally feeding its own inflated prices into itself.
Let's also not ignore that we are talking about housing here, there is a strong ethical side to not trying to price people out of places to live.
In fact, the lawsuits claim that RealPage shares "peer lists" with clients that tell them exactly who else is providing data to the company within a specific distance of their property.
This sounds like reassurance to a landlord that peers will mimic the same price moves. If true, I would call that price fixing.
Another kind of marketplace that provides detailed information on the other bids and asks is ... every functioning marketplace you have ever heard of. Commodities, stocks, futures, farm produce, everything.
Does RealPage give this info freely to renters, or is it hidden behind a subscription or fee and meant for landlords only?
