The article explains that this is the first time since 2020 that prices stopped increasing, which doesn't mean they are at a level where people can afford them - the article itself attributes the lower purchase power of the average family as one of the main drivers for why they stopped raising. The article also explains that maintenance (expensas) are 22% of the final rent price and those increased 170% from last year. "We stopped raising prices because we priced everyone out" is definitely what I'd call "out of control".

Anecdotally I also know three families who had to move back to their parent's house because they were priced out of the rental market. I won't say that all of this is Milei's fault (although I do have thoughts about his handling of the Rents law), but nonetheless the current situation is far from good.
