Her balance is going up every month.

Looking at that picture again if there are weep holes they are underground which would minimize or negate their effectiveness.Water, vapor, moisture, etc always gets into the cavity and that is ok.

It would also vaporize 80% of the STRs in the city.

I'd use Hardi coated with dragon skin or similar...some kind of real vapor barrier....

I used a penetrating concrete sealer, then an insulating vapor barrier/underlayment, and on top a floating luxury vinyl plank floor.I also installed a ductless heating/air conditioning system for that space.

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.

If your seller is paying a mortgage, she should be able to contact the new lender and get her balance.
