(For a Video to watch, which says that the world economy is contracting at least 10% in 2020, due to COVID-19; on U-Tube, there's "COVID-19: Why The Economy Could Fare Worse Than You Think/ The Economist", & released by the Economist mag, on May 27th, 2020.)

Knob and tube, vermiculite, lead...all generational stuff that might have been switched out or still be there.

Another company said they cannot insure the house because it has knob and tube wiring even though it is Not Active.

@Denny Robert There are tons of you tube videos out there.

The sub-fed panel has been placed in the stairwell which is in direct violation of the code.The neutral and ground wires are attached to the same buss which is a safety hazard, and needs to be remedied.Nearly all of the lighting and receptacle circuits show evidence of rewiring but the ground wires do not show conductivity to ground.This is evidence of poor electrical installation and possibly using old knob-and-tube wiring to feed these circuits which were found in the basement.Also, there are broken boxes and unsafe wiring practices evident throughout the inspection which led one to believe that the work was performed by an unqualified individual.The cheated wires must be found or the entire ungrounded circuits may need to be rewired.Pricing to move the sub-fed panel, properly install bonding and grounding, and correct the ungrounded circuits $3500-$6000Rear apt No entry was gained.The Electrical portion of the Home Inspection report shows ungrounded receptacles and possibly more.Considering the evidence in the rest of the building, it is possible that the circuits are also poorly installed by amateurs.

You tube it and replace ur self.Or get a new plumberYou should be able to replace a heating element your self.
