There’s a new company in the US that produces them as electric vehicles, they have back up cameras, are street legal, Bluetooth radio, etc.

Same thing with the electrical box.

 $200/psf doesn't sound too extreme for San Diego.But when you say full gut, do you also mean all new electric, new plumbing, new roof and gutters?  

They come with plumbing and electrical already built into the home.

Them being the 3 mechanicals (HVAC, ELECTRICAL, PLUMBING) and ROOF.

Here are some that I'm aware of:- Galvanized pipes - typically 40-50 useful life, could rust from the inside out, could get eventual pipe failure- Zinsco or Fed Pacific electric panels w/ aluminum wiring that could be a major fire hazard- Wiring in general (e.g. knob and tube)- Asbestos in the walls- Lead paint- Heating system - boiler?

They come with plumbing and electrical already built into the home. 

In my area, the most common are garbage and sewer bills, but they could include just about anything like water, electricity, etc.

.- We designed the units for low maintenance (tile floors, only electric - no gas fixtures)- We had 9 parking spots for 6 units so we rented out the 2nd spots

Essentially we paid the taxes, insurance, and electricity to live in the home.
