The hookups will be from the home's main systems, with the electric sub-metered.

Such as the roof needs to be completely replaced (there is a ridge sag and seems it could fail, rafters aren't place correctly), the porch needs a larger joist as its sagging down as well, the basement still has asbestos, the basement needs waterproofing as there is a moldy smell and minor water leakage, barely update the 1st floor unit, update and correct the electrical (relocate a fuse panel in a bathroom), brand new panels in the basement with a larger feed coming in, concrete steps in front and rear of house are in need of some repair, the boilers may need to be replaced, replace a few broken windows(completely shattered, just a piece of plywood covers them now), the lower roof gutters were nailed directly into the shingles, there are no GFCI's in any bathroom or kitchen, and a few other fixes.It would be an FHA 203k with 3.5% down$9,600 per year in taxesGarbage is included in taxes, tenants pay gas and electric, owner pays waterThe 1st floor unit is a 2/1 rented for $1225, they have exclusive use of driveway, backyard and the basement. 2nd/3rd floor unit is listed as 3/1, however there is 2 bedrooms on the 3rd floor with a bathroom.

They both have solid roofs, electric to the pole and city water as well as natural gas.

It isn't...not only do you have salt/filter costs, but you have electricity to run the pump, plus some jurisdictions charge an annual well tax.

There is a wall down the middle ending at a "common" room in the rear where both electric meters are. 

I can do most of the work including electric and plumbing( those two are illegal around here).

For example, a ticket that includes electrical and plumbing issues may go to 2 different people so this slows down the process if they are mixed together)Also, being able to submit online requests is a privilege. 

Your expenses are your debt service (mortgage), taxes, insurance, property management, utilities (heat, electric, trash, water/sewer) some duplexes already come with separate utilities for each unit.

I was checking out the electrical box on one of my units on a service call, the box is in a closet.

Purchase a cheap moisture meter and see what the moisture content is on the dis-colored areas and compare to the non dis-colored areas.I have had this problem before when the tenant did not run the AC (trying to save on electric bill) and when buying a house that had beed closed up for a long period of time.Do not use bleach.
