The second is to remove/replace the Sheetrock.

Alas, NC Realtors removed their form years ago.

Then you have whatever time you negotiated (often 2 weeks) to remove conditions.

So, if the deal is contingent upon the removal of a person, I put that in the PSA.

I’m also having the termite damaged wood removed and replaced with new wood when I redo the back siding in the next 4 weeks.  

In one of my own personal properties we chose not to have a hot tube and we removed almost all exterior light because of the activities we are steering towards!

That's what I think a fair price is.It does depend on how far it is to the roofing supply store, how far it is for the workers to travel, if there's any rotting wood that needs to be replaced and how busy they are (busier = higher profit).You could buy a couple ladders, a compressor, a 100ft extension cord (14/3), 50 ft of rubber air hose, a roofing nail gun, a caulk tube a couple shingle removers and pick up some day laborers who know how to roof. 

Tried to go with Fire and Personal Liability (removing Wind and Hail) to reduce cost but haven't found any offerings.I wonder if other landlords/investors have some good strategies to tackle this challenging environment.

Use the "search the site" feature of BP and you will find a wealth of good info on the topic of "smoke odor".We remove carpet and pad. 

If you don't like it I'm sure you can get bids to remove it fairly cheaply, then put up your Hardy plank, or whatever.
