Converting Electric on SFH to Duplex--Big deal??

[Martin G.]

Hello ! 

So, I've come across a nice 4 level SFH in Cincinnati that I would like to owner occupy as a duplex. The actual splitting of it from an entry way and putting-up-of-walls standpoint seems pretty cut and dry. HVAC is already dual and it was in fact a duplex at one point in its earlier life.

How big of a deal would it be it to split the electric into 2 meters  ? 

I'd appreciate any thoughts and advice. 

Best regards, Marty
