Bigger drop at end of year.Great Recession was the same...tech crash too.I'm on my phone so can't pull up the charts, but it's the natural psychology behind the market.After this stimulus passes,  likely a jump will happen and you'll feel you missed the bottom.

They already have negative shareholders equity, and only had ~400mil cash on hand at end of 2019. 

When you give tenants something for free, they have a tendency to abuse it.

Had a nice group apt but at end of lease landlord booted everybody with plans for a significant rent increase.

I can only speak to my own experiences, and I have a unit coming vacant at end of month.

Balloon payment at end of 5 years?

Finally kicked them out at end of 2019.  

Both parties agree on condition up front, and both agree on condition at end, you are less likely to get pushback if you withhold all or part of the deposit.In your situation, no deposit does not technically mean no liability for damages, but obviously harder to assess, particularly if you don't have any type of documentation of the condition before tenant moved in. 

I have only been told a deferral with a ballon due at end of deferral period.

Many (should be all of them) state it goes MTM if neither party requests a change at end of lease.
