Everything is going smoothly but the one concern I have is a metal tank found during a scan. 

Whose to say that I couldn't purchase two properties with the same amount of cash if only I were patient and waited until 2020 Q4/2021 Q1 versus buying one (which met all criteria) now? 

If you are determined to save, maybe keep it in the form of precious metals.

Will also pick hvac people's brain about adding a cooling coil to existing furnaces.

You can get radiator covers with perforated sheet metal on the front that cover the entire radiator like a box or we had flat metal covers on the top with 1-2 inch sides.

You need starter shingles, perimeter metal, lead pipe flashing ( rubber ones last 10 years, lead is forever) ridge vent if the building can utilize enough of it.

@Paul Cox Next week I will be on a cruise ship hanging out with 80s metal bands and @Paul Sandhu.

It looks like there is a custom piece of bent metal trim on the siding on the right hand side of the photo. 

Tile floors for example may last 100 years while carpeting and drapes are good for about ten on average or a roof, anywhere from 10 years (roll roofing) to composition 20 -25 or metal roofs 50 years or more and tile roofs even longer.

I don't have a compressor this large, but I do have large metal working tools with dedicated 220 volt circuits.
