You need a wet saw (not expensive) and 10% more tile than you think you need.

You also need to check the electrical that got wet as that can be a safety hazard.

Once it gets wet, it solidifies and we can't get it out (I've even gone Rambo and used an electric drill with auger bit and it took 30 minutes to get it out!).

Check out the wet areas very close.

I think you have a great plan to get your feet wet with a flip.

Go down on walls about 2 inches so you cover well.Done with ceilings you can border tape so wall paint doesn't overspray with the 12" paper type tape with sticky edge,,Walls next, cut in the edges of ceiling and corners of walls, by hand, then spray, after sprayed have someone go behind you with a roller and with textured walls this will work well, wet the roller with paint first and then you'll hardly have to wet it again..Trim and doors next.If your painting the trim like in a whole house I usually would recommend doing all Ceilings and then the trim next.. especially if it's bare floors.. sand, prep and spray, first remove all door hardware, hinges, and back tape the windows so you first put a layer of tape around the edges of the glass, then you cut plastic and tape the plastic to the tape that's already on the glass. your not taping it to the wood or vinyl edge but basically sealing off the glass.

They sent pictures of a home mold test they did as well as pictures of mold growing on his mattress (his mattress was not on a frame, it sat directly on the floor which got wet during the water intrusion).

Long time reader but it is time to get the feet wet. 

Without gaps, it has no place to expand, do it bows up.When a board gets wet on one side, that side will expand.  

Ours was coming down a wall which was not wet and seeping to low point in the floor then seeping into the wood.
