If I were you, I would just assume she is working there and do everything reasonable you can to mitigate the risks of exposure (ex. staying as far away as possible from her when she is home, disinfecting surfaces, etc.) 

The other problem that surfaces, and perhaps first, is when the insurance company submits to the mortgage company a request for payment of the property coverage (even if they knew all along it was being rented and the coverage was a landlord policy). 

Fire is tricky because there is a fine balance between surface damage and structural damage. 

I generally interview a lot of candidates and I verbally decline/weed out those who just on the surface would not qualify (smoker, guy with 15 snakes, person trying to re-negotiate the rent down, someone asking me if an eviction will be a problem or if I plan on calling their last landlord, or asking about a payment grace period).

Just shooting the BS on the back porch.Does not include office cost or revenue.There is a lot of demand for Boat/RV storage, but the payback is really far out there, with Rock for surface.  15 to 20 years.Their cost to build, let alone the headache/risk is in the $3mm range, so they are selling right at cost reduced for some age. 

The rot comes from the water “sponging up” through the unpainted wood on the bottom surface of the column where it sits on the concrete.For the deck, if the yard slopes away, you can bury a longer black flex pipe so the water comes out 10’, 20’ away if you want.

i would paint the surface with any membrane like the one use in bathroom to prevent any of the pop corn falling off , then i would dry wall the whole area, good luck 

The structures were also built before set-back rules were in place and are close to the road without paved parking surfaces.

I am thinking about removing both tenants asap and trying to get the smoke smell out but removing all carpet, whipping down down every surface, getting ducts cleaned and running an o-zone machine if needed.

Its essentially the same clay that causes you trouble at the surface with cracking your foundations, buried, compressed, and turned into a rock.
