Of course the padding and carpet have absorbed it, but on pressing dry towels to it, I am pulling some moisture out.Do I let that air dry, put a fan on it, aim a space heater at it, pull the carpet and pad back, what?

Anyway, just my 2 cents, if you don't have a contractor/rehab background, there's always lots of surprises in flips (permit issues, surprise moisture/rot issues, plumbing, electrical, you name it) - I'm sure you've heard some of the stories.

But I'm looking for a general purpose handyman who can do basic things (dryer vent installation, moisture barrier repair in crawlspaces, shimming warped doors, etc).

It would be my guess the vinyl hasn't been keeping the water out either.Bottom line is that no siding is going to be completely waterproof and you want to do your best to keep any source of moisture away from the home.  

An engineered wood floor of good quality( not the box store 5/16 garbage) would be a good choice and handle the temperature and moisture extremes better.

Conduits and panel is exposed to moisture.

This is easier to maintain than messing with paint due to high moisture / humidity issues. 

However, it is a potential weak spot as it is very susceptible to moisture damage and there is a lack of accessibility to make any repairs which is why the GSE's will not underwrite them.  

There appears to be some stains indicating seepage.We just did this kind of foundation repair on a house with steel beams 6 ft oc with an interior moisture barrier and an interior drainage tile with a sump.  

The area behind the wall would be filled with gravel and it would have drains to allow any moisture that gets behind the wall to escape.
