Concrete is a pretty good insulator though.

You can pretty much figure on there being no insulation in the place.  

One home has all original insulation and HVAC equipment, and is $15-20K less than a home with upgraded high R-value insulation, and maybe a nifty mini split heat pump that does heating and cooling.

Will banks ever think outside the box insulations like this?

I insulate the attic space.

Let's see - $7K in damage done by a tenant in one unit, others had a roof repair, a floor replacement, a new shower/tub liner installation/spackle/paint job, insulation in the basement, 2 dryer repairs, a door replacement, a bathtub/shower refinishing, and a 3 month vacancy....I'm sure there was more, but I've chosen to block it out ;)All properties except 1 were cash flowing, but so much outflow in one year was a disaster.

Supply lines are all copper.4) Envelope:  The house has minimal to no insulation and the windows and storms are all original.  

All new Electrical-Plumbing-HVAC then it will need insulation then drywall, trim, paint, floors, etc etc you get the point.

They are very energy efficient and stuff the walls full of insulation.

A Class A asset in a metro area is more insulated from risk and with less unknowns - safer placement of equity.
