If you have a high water table or incessant ground vapor, you will have spots of separation. 

A professional may have some insulation or vapor barrier solutions, too, if the simple dehumidifier does not do the trick....best of luck

Plus, much of that "wealth" vaporizes with a dip in the market.Are the investors saying veterans or new since last recession?

No portable kerosene/gas/incense burning; limit candle burning; no excessive odorous chemicals/sprays/vapors; restrict toilets to biological waste and tissue paper; keep drains clear No BBQ’s or open fires in units or under eaves, canopies, porches.

Now if you have a vapor barrier this can be reduced down to 1 sq ft of ventilation per 1500 sq ft of building area per 1203.3.2 exception 2. 

I was wondering myself.I also wanted to ask a related question... do the vapors from the vape products cause any odors, discoloration, issues, to a home?

It’s a block house with plaster directly applied to the block, no vapor barrier, no framing and no drywall.

No vapor barrier so moisture is present 100%.

I want to buy all the income I can.the expansion of the real cash and the "vapor paper" is what troubles me the most.

Especially anything main floor where you don't necessarily need a water vapor protected like you would put in a basement.
