People who can't pay rent now are unlikely to be able to ever pay it back later. It's probably better for everyone to just write it off.
That would probably be better, but isn't happening. I think these landlords should have planned ahead and had six months of emergency funds saved up, just like McDonald's employees are supposed to.
Definitely, that would be a better outcome. However the rent isn't being forgiven - it will possibly be sold to a collections agency, who would hound the renter to get something back from some of the renters.
If they get it later, what's the loss they get to claim on their taxes?
