Toss all incandescent, fluorescent, halogen, mercury vapor, etc.

Properly installing a vapor barrier is critical if you have a crawl space.  

The brokers "higher offer" was vapor the 2nd time, and likely the 1st.

In hot humid climates we are very susceptible to what is referred to as vapor drive.

This deal was pretty much turnkey other than needing a new vapor barrier (estimate for $500) which I plan on doing myself.

Of note: this has not been evaluated by an attorney, and I have no way of knowing if the language would be legal in your state...NO SMOKING POLICY: No smoking, to include cigarettes, pipes, cigars, or any other tobacco smoking material, and/or vapor like products is allowed within the structure of the building; including the rental unit, basement, or garage, or outside on the adjoining grounds, either by the Tenants or their guests.

Site-built homes have numerous areas in which to place utilities, and they usually don’t close the only escape route for occupants, as happens many times in mobile homes.”In addition, pre-1976 mobile homes had less insulation in walls, ceilings and floors, uninsulated air ducts and no vapor barriers in their roof cavities, making them an increased risk of fire hazards.

The sellers have recently put new insulation and vapor barrier in this area of the basement (it would appear to mask the moisture problem?)

Go look at soil vapor extracting costs/ sparging/ lawsuits...
