If the damage is that bad, they should be replacing the dry wall in the ceiling; if it is a small stain it is an easy cover up with primer/spray paint and repainting it. 

Dude just one point that mold is nothing its so common and the inspectors use this to scare you which they have done.. a little bleach spray it on wipe it off boom its gone..

Any jackass can get out there with a spray gun and spray everything in sight, but I'm assuming you want it done neatly and your house to look good. 

Spices, sugar, oils, cooking sprays, teas, all left by previous guests.

But I am going to spray this weekend. 

Are there investment friendly mentors that are willing to bring the water hose spray down a tad for me so I can learn next steps?

I'm looking through the spreadsheet and I think it's worth mentioning that it's possible to spend a lot less for certain material items as well as labor in many cases depending on how frugal you want to beinterior door with hardware: $5-10 used, $30-50 newwindow: $10-50 used, $100-200 newlight fixtures: $1-10 used, 6 pack flushmount at lowes for $44fan fixture: $24-60 new water heater: $250 newtoilet: $50-90 newsink: $40-200 new faucet: $10-30 newtile: 0.49-2/sqft newappliance: $20-200 each appliance usedmy last rehab was:60 elec permit cost + 300 elec repair (tenant destroyed meter box causing house to be condemned)1600 material + 1500 labor flooring for 1400 sqft500 material + 600 labor spray paint whole house semigloss and patch some large holes$30 for 4 interior doors which I put in$10 mirror for bathroom$100 paint porch, stairs, and stair rail brown$50 fridge, $10 burner plates for stoveI also spent at least a few hundred with help on cleaning and taking out the trash and some other expenses here and there which altogether added up to about 5 thousand.I spent maybe 30 hours over there in total on the weekends.

I recently got a PLM Summary Report on a property detecting 2% Chrysotile in the drywall in the garage and 5% in the popcorn ceiling throughout (looking like just in the spray texture).

Although there are companies who use lower standards (paneled walls, presswood floors, etc), the companies I have worked with in Florida use higher end materials like tongue and groove plywood floors, 100% drywall construction with 2x6 walls, spray foam wall insulation, granite counter tops, etc...and then we delivered them in 2 pieces via semi truck (or as many as 8 pieces depending on size and number of floors).

@Alan DeRossett - this was under at least 7 layers of paint, i even tried those little pin punch rollers and remover spray.
