The rental market is a decentralized network, with companies like these the network gets routed through a central node and the operator of that node has pefect visibility while the connections being routed have no idea what every other connection is doing like a dark pool, it's the centrality that makes it an analogue.
I could think of several advantageous moves like artificially inflating rents then favoring a well paying client by keeping their rents lower than the market. Investing in property spread out across shell companies and then have the algo favor them in a non-intuitive way.
