Step 2 (and only at the tenant's discretion) is to file a restraining order of sorts against tenant B.

You can then pay a VA (I use a great one from UpWork for $3.50/hour) to do all sorts of analysis.

+1 for Todd's recommendation...though I would never actually advocate doing something outside the law.Get creative, or get in line with an attorney so you can sort this out as soon as the moratorium is lifted.

Is there any sort of closing - we must need to record something somewhere? 

You walk out (after a few weeks of course) with your original $70K back (maybe a hair more after closing costs), an extra $175/mth of income on your 1003 application (even though your real income is much higher), and you go do it again. 

As a word of caution, if your thinking you can use that to beat people's prices down and your installer selection method will simply be whoever accepts the lowest cheapest price, just remember that selection process when things go bad and your pulling your hair out screaming "why....

Sorry about your situation.I own condo units in Michigan, and while Michigan has yet (to my knowledge) declared any sort of pest (mice,roaches,bedbugs) definitively as an issue of 'landlords at fault' or 'tenants at fault' I have generally taken it upon myself to deal with the issue and, depending on the issue, trickling any associated costs down to the tenant. 

@Joel Owens, Hey Joel, I'm wondering what sort of commercial investments you would target coming out of this downturn besides STNL?

Vs if i had a mortgage and 1000 of that 1600 goes to my mortgage and 600 goes into a “repair fund” or some sort account strictly for maintenance on that property.

If they need help past that period (and have exhausted all other options - SBA etc) I plan to offer a payment plan of some sort.
