Also build walls with 2x4 studs (and a door) around the furnace and insulate the walls with 3 1/2" fiberglass.

The kicker is we need / want them black framed in either aluminum or fiberglass

Replacing fiberglass top and surround with steel tub and tiled shower, new tile floor, vanity and lighting.

You get better resale value from tile over a fiberglass insert.

He gave me a quote of $2k for adding the missing fiberglass insulation in the attic.Summary / Recap$4.2k (electrical repairs)$5k (plumbing repairs)$2k (HVAC repairs NOT a new system)$2k (insulation)---------------total = $13.2kIs it outrageous or offensive if provide the seller with an offer of the current price, minus the total cost of repairs quoted by the inspectors?

They offer both fiberglass and vinyl.  

This included fiberglass insulation, new drywall, new vapor barrier.

I am getting bids from roofing contractors and am debating between the traditional 2 ply asphalt (cap sheet, hot mod layers of modified felts or fiberglass), versus TPO, versus PVC, and also underneath them, a tapered insulation to give it a bit of pitch for water runoff. 

., but a very rough estimate for labor and materials to install fiberglass batts, per linear foot of batt, is $1-2.So, 146 linear feet, at 16" stud spacing is about 110-120 wall cavities.  

For separate units here in the Seattle market I would do z channel or bi metal sound isolators fill the cavities with fiberglass insulation and use 5/8" sheet rock.
