So I took down all the drywall & had to toss the insulation behind it because it was rife with the stench of smoke residue.

I have done many glass block windows which are insulated, come in many designs and colors and let the light in and adds to the value. 

When gutting these older Shotgun doubles you start exposing 100yr old Barge wood with burlap insulation still intact.

In the winters you can either remove them or insulate them.If you don't want to provide the AC units, I would have clear language in my lease about which windows they can be installed in, that they must be installed safely, can/can't be screwed into window panes, etc. etc.Ceiling fans are unnecessary effort in my opinion. 

Now people actually look at roofs and insulation more than kitchens and bathrooms!)

But I will need something more insulated and firm, because I'll also rent each side out to unrelated people. 

They will consider whether the walls are still plaster, of if someone has torn out the lathe and hung insulation and sheetrock. 

You'll need to call banks and ask them how the financing works as well.Then you have to find the subs to do the work for you and get quotes for:Plans, Clearing, Dirt and Dozer Work, Permits, Temporary Service, Well/Septic|Public Taps Installed, Plumbing (rough-in), Foundation, Framing, Windows doors ext, siding, ext painting, roofing, Plumbing (stub and trim and service connected), A/C, Electrical (int/ext), Insulation, Sheetrock, Cabinetry and Counter Tops, Floors, Int. doors and trim, Int.

I had an inspector go out and take a look at it during construction and he found MAJOR problems ranging from possible asbestos insulation being airborne, lead-based paint cracking, cracks in the foundation and crawl space, old knob and tube wiring, moisture and mold issues, roof shingles replacement, and loads of other issues.Rather than talking about them, I made a playlist of the inspection here: https://www.youtube.com/watch?
