Built in 1950, it has a new roof, new heating and air, all new electric and other than that the rest of it looks original and beat up.

Plus a lot of other expenses are missing: I don't see water, electric, gas, lawn, etc...

I have a bachelor of science in Computer & Electrical Engineer.

The only reference I have is for my duplex and triplex properties in CO; sewage, water, garbage and share common area fees paid by me; tenant pays gas and electric.  

We don't have the dimensions, know where any electric or gas lines are, if there is an exhaust fan, etc.

Sub pump stop working due to an electric outage?

@Jim Adrian it’s a complete guy, sans most of the flooring, because the place has been vacant for 10 years, the plaster ceiling is falling down everywhere, walls need to be reconfigured to make it fit a SFH instead of a Duplex better, Mechanicals all need replacing due to rodent/critter damage, and city code will require electrical service upgrade and new water service, etc… It’ll be a fun project, has good bones, just the soft meaty stuff inside that sucks.

For example, even in this post you mention that there are two meters -- do you mean electric or gas?

Electric floor boards heat I would run away from the heat bill is huge. 

I assume it has electricity under a single meter.
