If you're going to do that, assume that when walking through the doors, there's nothing on the walls, electrical all needs replaced, HVAC needs replaced, etc. 

(with a single gas and electric meter)I am looking for some expert who could help me rezone this and  convert this to condos  or multiple units with separate meters.Please recommend

Naturally, there is a benefit to HVAC and Electrical contractors.

Electrical?

I am estimating building costs around $100/sf, but wasn't sure if that should include permits, or costs to bring sewer, water, electric, etc from the main road, building a road, and that sort of stuff.

What are the utility expenses (electric, gas, water, sewer, trash)?

Some of the major rehab involves Siding, portion of roof, new sidewalk, splitting electric (new panel boxes and meters), heating (new furnaces and re laying of duct work), water (new water heaters), portion of broken sewer pipe replacement, replace electric wiring to 2 units, new kitchen, bath, flooring, windows, doors (interior and exterior) in all units. 

A 3 bedroom all-electric house (with a heat pump) should rent for $1085.I wouldn't get a 4 bedroom rental in that area. 

Mold, rot, electrical, bad floor plan all can be fixed fairly quickly.
