An electric dryer will run up the bill of that unit quickly , where a washing machine wont nearly as much . 

I got an address for it, cleared some land and hooked up electric.

You can try to research to make sure the utilities are there for sewer, water, electric, etc. 

Then there are some in between that may have a composting outhouse and a hose spigot, but no full electricity etc.  

Have done tons of cleanouts on evictions too, nothing surprises me anymore on how some people can live.The hot water tank had things growing in the hot water overflowing, the refrigerator was tucked in a back shed area where everything inside had liquified. 

I went to a public hearing on a red card that the town fabricated because a structural inspector decided to do an electrical inspection early.

Doing DIY on plumbing, electrical, or structural.

But I'm confused/curious as to why this Electrical Contr is so willing to burn bridges over couple of grand, is he just stupid?

A good HI will go over your house with a fine-toothed comb.If you can find an Ex (or Retired) HI that is also Certified, that would be even better, since they will understand the structure/electrical/plumbing systems in more detail than a regular HI...

You think through the major systems in the house (roof, exterior or tuck pointing, hvac, plumbing, electrical, unit turns, common areas) and if they are all new you should be good for a few years (5-10).
