Just remeber to find the moisture source or it will come back eventually.

I purchased a moisture meter and checked the drywall and baseboards in several spots.

Kilz is good stuff, but won't necessary cure mold.Do you know how the moisture got into the closet?

Evidence of moisture on some of the walls including under a window well.

Smoke penetrates everything: insulation, carpets, any unsealed wood framing-interior of cabinets-lite fixtures, hvac system, etc.

A lot of folks do it (https://www.biggerpockets.com/forums/67/topics/973...) but some materials experts are concerned with moisture and breathability issues caused by painted brick.What I've found is that painting won't change the value (technically), but curb appeal and making a good impression on the appraiser always helps.From the picture, it looks like you will be getting a commercial appraisal so the numbers matter more than how it will compare to other properties.I'd wait.

First off, get a moisture meter and get a reading off your slabs.

Because there was nearly 100yrs of paint layers on the casings, it took multiple coats and of stripper to even penetrate.

Any wall covering that is attached to the wall where water came in, IS going to be wet behind it (including insulation, if any), and the only proper method of drying it is by removing some/all of the affected area, or using a dehumidifier with tubes inserted between the foundation and the wall covering and high volume fans to quickly (it often actually takes several days to get all of the moisture out) and completely dry all of the materials.

Increase the ventilation and check for moisture thru bath fans which need to vent to the exterior or close to an opening etc.
