It does not cost the landlord except for the labor and materials.

To remedy that, the carpets should be ripped up and sealant applied to the subfloor, at minimum.There are also tiles in the smaller upstairs bathroom that are lifting up and creating a safety hazard; putting a rug on top is not a sufficient solution.The house is in a condition that materially interferes with the health of household members.

Do you have any more materials to share with me about the market? 

In that case you should get an attorney involved as encroachment would be a material issue that if known should have been disclosed both to the broker and to any potential buyer.  

Now just realize it will STILL need to be demoed , they dont burn it to the ground , and demo guys hate dealing with burnt materials . 

From my research, I'm seeing $100-$150/sqft depending on complexity and material.

Regardless of which holds true, for a company who represents to have a $250M portfolio to select this home to be showcased in their marketing materials at this time speaks to the operational disconnect that exists.

Little paint and the contractor I found let me buy the material and only charged me labor.

Replacing one bad fixture between material and labor can end up being 3X the cost of buying the better quality fixture in the first place.  

A lot has happened since starting, between material shortages in SWFL for a while, a massive hurricane, a period of power outage, damages to various parts of the city (and major damages to surrounding cities), high demand in labor/resources, a transformation in permitting systems, and a boom in construction in general.
