But, then you will be in a position to get rid of her asap once the moratorium is lifted. 

If the Moratoriums are not lifted for many months there will be a Hughe number of properties waiting to be auctioned, the golfball passing through the garden hose.And when the properties are auctioned at an unheard of number the absorption rate may be slow and many properties will go unsold and be rotated back into the next auction.

Let's say you want me to do a job that will require me to use a man lift to reach high up on a building to install some conduit and some lights.

The property management software takes away a lot of the heavy lifting though. 

One of my tenants was a severely disabled, retired doctor that couldn't lift her head up to look in her kitchen shelves or drive a car.

Here are your options, dont close, and plead for your ernest money back  (you wont get it) or close and see what it takes to get the order lifted. 

You could also try cutting the one that sunk in half, carefully lift it up and put concrete under it to bring it up to level.

I also have a clause (lifted right out of Bigger Pocket's The Book on Managing Rental Properties thank-you-very-much) about anyone staying longer than 14 days is someone who needs to apply and be added to the lease if they meet the requirements etc…My worry is that the company will pay the rent, have this one person on the lease and then will cycle 'visitors' through the property essentially as a short term hotel.  

You just squeeze the two black things that look kind of like handles and then lift it up.""

As for the hot water tank / HVAC pans, it depends, not required that I know of, but if you want one you can go buy it and have anyone install it, just lift the unit up and slide it under.
