Now, do it in a stone house, 1940, field rock exterior before you blow in insulation.

Today's exterior steel, and vinyl doors are much better with energy, insulation and weather stripping, therefore no need for storm doors.

The way it is setup you cannot remove insulation without removing sheetrock.I'm not a pro though, is there a way to salvage this without a fear of mold issues?

(e.g. nest thermostats, spray foam insulation, or one of Tesla's solar roof systems )  but adding some very basic products that this property was lacking. ( I think a lot of mom & pop C & D properties are in the same There was zero insulation in the attic ( Added R-38)Old Single Strength Wood Windows ( Replaced with low-e replacement windows)HVAC 12 Year Old 10 SEER ( Replaced w/ new 14 SEER HVAC)12- 14 year old appliances ( Adding Energy Efficient Appliances )Definitely the basics, but just making those improvements has definitely directly or indirectly (depends on how you look at it) impacted the NOI and the overall tenant experience.

In temperate climates attic insulation is way, way more important.

Also they tend to shed snow cleanly as compared to shingles which might 'weep' the melting snow, re freeze, and then create an Ice Dam which can do damage to not only the siding, but to the insulation and ceilings.

We just framed it all out, insulated, 2 windows, dry wall and it adds 300 sqft of living space.

If that is an exterior wall I would make sure the outside is not leaking into the structure, insulation then drywall.

I found some old knob and tube wiring in the basement; saw a good amount of asbestos insulation around pipes and some lead paint in the basement.
