alt Hacker NewsRecognizing your frustration with reality's failure to adhere to the academic: the fact is that rent rates for corporate-owned units generally don't go down. At least, not in recent history. In the rare cases where cartel behavior doesn't work to cement rates, and owners have to respond somehow to market conditions in order to avoid cash-flow disruption, they will offer "specials" that lower the out-of-pocket cost, but not the on-paper rental rate, for a unit. Your oft-found "1 month free"-type deals (that are actually a monthly bill credit for the initial lease term). Upon renewal, your increase is based on that paper rate, not what you were actually paying.
Recent history has been corporate rents not decreasing amid tight supply, the question being asked repeatedly (and repeatedly not answered) in this thread is “how exactly would landlords continue seeking high rents if housing were no longer scarce?” The only answer so far has been “by buying up the supply and renting it out” which completely ignores the obvious fact that renting out housing may reduce the supply of purchasable properties, but increases the supply of rental properties. There is no reason to assume collusion among a set of landlords would be enough to keep rental prices high if supply is no longer tight. So how exactly would landlords continue seeking be able to keep prices high if supply continues to increase?
