Month 1 drawings/awaiting permit to be issuedMonths 2-4 - rehab (90 days for 120k in work), make sure to account for inspections Month 5 1 week touch-up, photos and then listMonth 6 under contract(assumes it takes 30 days to go under contract from original list) and then buyer needs 45 days to close which brings you to middle of month 7.Each project is different and you can shave a few weeks here and there but that's a pretty realistic timeline.

Most I’d do is drill a few small holes in the ceiling and foam in some areas that are maybe not insulated right or where holes like pipes go through or vents that should be the easiest way to satisfy them Sorry if I wasn’t much help I’m in wa state

@Michael Wolffs We just finished replacing a 12' section if external wall and sill plate that had rotted as the result of a through window/wall AC unit that had allowed water to leak down into the wall for a prolonged period of time.We also removed a through-wall natural gas furnace at the same time and applied 3" of closed cell foam to the external walls on the main level.  

We shaved it down and hung someecard fresh drywall.

Maybe a solid piece of foam or insulation sandwiched between two pieces of thin aluminum or PVC/Vinyl?  

I had them cut out and keep them at bay by using some foaming root killer every 3 months. 

Lastly, anyone have experience with Liftech or any other concrete slab repositioning with expandable foam??

It has 22 mil wear layer and costs $2.89 per sqftDuralux Windmill Oak which is 5mm thick with foam back.

But my houses built in the 40's have given me the most headaches and surprises.  

And now days you can insulate the ceiling with foam.
