He owes you rent until he vacates it.We have just started this pandemic situation. 

You have zero recourse to collect money from them in a normal time and certainly not in this time of the virus pandemic. 

Maybe more.Most people would be "reasonable" by hanging a line in the laundry room and drying clothes old-school when all reasonable efforts to replace the dryer and stay safe were exhausted during a global pandemic.

I have a tenant who’s using the system (pandemic) to her full advantage.

When I took over the building it was making 36k gross rent per month and there were 8 vacant units, now the building is fully occupied and making 48.5K a month.The owner is really happy with my results and the fact that I got a new tenant during this pandemic.

I think this pandemic may have sped up the process, but I think we were moving in that direction already.

The tenant was upfront with me in March and stated that she had been furloughed and had moved back in with her parents to wait out the pandemic.

Not having enough in the bank to afford to put on a new roof, or pay the mortgage while you fight with your insurance company after your building burns, or you're in the middle of a pandemic all of a sudden and your tenant decides not to pay for several months and you're not allowed to evict them.I am really against using all equity to put it into another property. 

I also have 3 children (another on the way) and have been rocked by the pandemic economically.  

Lower income neighborhoods will also unfortunately be hit the worst with the current pandemic/economic unemployment as we've seen it's mostly lower wage earners losing jobs.
