I really dislike particle board especially the sink base cabinet.One leak and they swell up, crumble and it's irreversible.Tenants always put too much stuff into their sink cabinet.  200 bottles of hand detergent, DW detergent, cleaners, bleach, comet, rolls of kitchen napkins, candles, extra kettles, and 500 supermaket plastic bags filling every air void existing in there meaning any minor leak will not be noticed by them until it's pooling on the floor.

What is a female hygiene product in paper or plastic?

I don't think the structure is damaged or weakened (no leaning that I can see) but just holes where branches came through and plastic lining dangling some.For the black mold, will using bleach water to clean it all up suffice?

This is really easy to do if you have plastic drain piping from the sink to the trap adapter in the wall. 

As long as the wall is open install a code compliant (ours are some kind of high strength plastic) glass block window. 

I'd wear a cheap plastic rain suit, goggles and mask. 

The area has a gravel floor covered by plastic, so it is definitely not meant to be used regularly.

I was actually looking at a 10 unit multifamily, but own one of the duplexes he describes with a thermostat that has the plastic box over it.

It puts the well casing above ground level,,which is MUCH quicker and easier to work on.I was going to , but with this well has steel pipe instead of plastic .I have the parts to do it , but time constraints didnt allow me .

put a tarp down in the trailer plastic over that, throw it in and wrap the edges together.
