For me, I will not be doing any additions at the moment, but from what I've read you typically need them for minor replacements of siding, framing, etc. as well as any work on HVAC, electrical, plumbing, etc. separately.

See if any of the electrical is updated in the house. 

It's the same thing as their other vendors (electricity, cable, etc) ask for, so it's pretty commonplace now.

Electric, water, garbage, repairs, all included.  

I wanted some repairs and updates done before it was rented (update electrical panel, change out a couple of outlets, some cosmetic updates).

Is the land that you are building on already subdivided and have electrical and sewer running to it ? 

I'm not too worried about the cost to heat, since the each unit has a separate electrical meter and the current tenants pay their own electric bill and seem to be fine with it.

ELECTRICITY: $25 (All units are separately metered.

I spent $500 to fix them.The explanation that property manager provided is the gas company won't turn on gas without  electricity being on, and the power company didn't turn on electricity until mid December.  

If you are looking for extra energy every day and am not a morning person at all—like me, take cold showers every morning.
