The exterior walls are brick with yellow insulation and covered in plastic moisture barrier.

You can try to paint or skim over the top, but the moisture in the paint and wall compound may cause the wallpaper to bubble in different spots.

I would expand this not only to include regular rental properties, but  vacation rental homes, condo's, Air BnB's, etc  Start of with simple upgrades like key-less entry, smart thermostats, security system and moisture(water link) control. 

You've got to be careful to mitigate rain and snow in these window wells, because they will tend to allow moisture to migrate into your basement.

I'm from Florida which is obviously very humid so even the slightest moisture exposure can trigger mold growth. 

The only thing to note about this is that it has to be installed with the correct glue and no moisture.

More importantly in a bathroom you want to seal the drywall well so that moisture can't get at it.

I do fix and flip but always use solid wood cabinets, boxes and doors, as they present better, aren’t affected by humidity as much and can take a beating.In any case, for fix and hold, I’d want a solid wood cabinet so they last longer and won’t require replacing as often, especially here in Florida where moisture tends to find a way to destroy things.

Per the inspector, this can allow moisture to enter the SE wire and corrode the meter bases and/or the main panels.

And when you get moisture behind a poor stucco job in our climate, you could have a $50K problem between the mold and the rebuilt exterior.One wonders if these new subdivisions will look just as dated as the 70-80's split-levels or the 50-60's ranches in thirty years.
