tl;dr: 2 years free rent with the condition that the tenant doesn't ask for a lower price. due to language in the contract the rent can not go beyond a specific (low) value. the loan isn't held by the bank but immediately restructured and sold as a CMBS (https://en.wikipedia.org/wiki/Commercial_mortgage-backed_sec...)
here is the reddit post that he recaps: https://www.reddit.com/r/nyc/comments/innhah/nearly_twothird...
Let me explain it to you simply: The landlords made a bad investment, bailing them out forces everyone else to pay for it. In the "it's my property" sense it's identical to forcing someone to house homeless people (although the comparison still isn't the same because the landlords generally don't live in the buildings they're renting out.)
Simultaneously buildings would be converting into condos because they were unable to fill vacant commercial space. As an example, two buildings where I worked had this happen: 70 Pine Street (AIG) and 75 Wall Street(JPMorgan.)
Doesnt the market meet somewhere in the middle?
And people who do this are always people with perfectly good couches in their living rooms but would never let a homeless person sleep there, but want others to give up a entire building.
