However while looking at it, I noticed that it only has 1 electric meter, 1 gas meter, and 1 water meter. 

  $30k for rough electrical on a 2 bed/1 bath + 1 outbuilding when its all exposed is laughable

waterproof leaky basement, remodeled bathroom, plumbing & electrical update as well as new fuse breaker box.

Both needed all new electric, plumbing, roof, HVAC, insulation, sheetrock, flooring baths, kitchens, etc. - everything.

New cabinets and counter top, little electrical and plumbing and lots of paint.

One night during autumn when the A/C is not needed (and is disconnected from the electric panel to reduce utility bills), I hear a noise of a machine or some engine running all night long, very similar to A/C.

The roof estimated repair cost is $32,000, I estimate the septic  is $30,000 since it failed completely, and other repairs (windows, doors, paint, floor refinishing, furnace, electrical) to be about $30,000.

I use sub meters for my commercial property - for electrical.

They pay electric.

Separate water and electric for each unit, all underground plumbing replaced in last 10 years. 2 sewer taps, 4 units on each- this is the only thing I could see giving me an issue of blame game if something happens. 7 units occupied with long term tenants, 1 unit needs replaced which we will replace with newer home and sell to new owner/tenant.
