>"The two roommates were also given one month's rent free and did not have to pay a broker fee, which typically would have cost them 12% to 15% of the annual rent."
There was actually legislation passed back in the Winter that effectively did away with the whole broker fee system.[1] I know a judge temporarily blocked this as per the article but that was only until June.
>'"But, he said, more apartments are also available because people just up and left their leases. While many left when the pandemic shut down the city, others left later when the protests over the killing of George Floyd began, Gavzie said.'
Generally you are legally obligated for the rent for the duration of your lease. So while a renter can "just up and leave", if they don't fulfill their obligations they can be sued. So if by upping and leaving a tenants pay's the remainder of their financial obligation then it would make sense that a landlord would give them a discount since they may be collecting twice on the same place for some period time.
