Any perspective on complexity rewiring a duplex?

[Mike Dorneman]

I’m currently having a duplex completely(3 bed / 1 bath, approx 1200 sq ft each side) rewired. They property had active knob and tube throughout. The home is about 100 years old and plank style construction (no studs or insulation in exterior walls). It’s looking like all in this will run about $10,000. I was wondering if anyone has gone through a similar project and what the cost was. I’m located in North East PA. Property is in a C+ neighborhood.
