Milei removed rent controls. As a result new construction of housing is actually happening. The increased supply of housing has caused rent to drop to almost half. Almost half. When you have static demand it doesn’t take that much to drop the price. Just a little bit of excess housing vs just a little to little can make that difference.
I guess it’s not a good time to be a landlord though. But it is a good time to work in construction or be a renter.
Perhaps poverty at 50+% is also driving this.
