Just factor in fixing the reason the basement flooded (could be easy like clogged gutters or extending the down spouts or maybe the sump pump hasn't worked because the electric is off or it could be expensive like digging around the foundation, parging the walls and then adding a french drain or could be real expensive and have a cracked foundation so you need to know) mold remediation and door replacement (if they're really bad) into the renovation figures.  

She won't even let us use electricity and I don't have a generator right now. 

All the setup incl. permits were included with the exception of the plumbing, sewer, electrical upgrade and HVAC reconnect.

We got the inspection back today; the issues are as follows: mold beyond the surface mold we originally noticed when checking the house out, wood rot in left side floor, damaged roof joist, poor ventilation in the attic and mold, many of the chimney bricks are loose, standing water in crawlspace--potential mold, leaking shower and toilet leading to damaged floor/ceiling underneath, plumbing material issues, electrical not all properly grounded. 

Rehabbing the entire building, bathrooms, kitchens 2 of the units were pretty good, plumbing electric, painting, etc.

We’re thinking about converting everything into split unit hvac since tenant pays electricity and boiler is getting old and costs a lot to maintain and run heat through four stories.

I estimated gas, electricity, water, sewer, and trash to be $225/month, which could be billed to tenants while I'm house hacking.

When I initially spoke to the seller she stated that they were upside down on the mortgage and had out about $30k into the repairs so far including HVAC, electrical, and plumbing.

@Irina Shetty One thing that stands out to me is the Electrical.
