Have you considered the additional load on plumbing and electrical?

Your plumbing, electrical, HVAC (includes all mechanicals) can only be pulled by a Master.

what purpose does it serve you to know how much he is charging for framing, plumbing, electric, framing material, electrical supplies?

(Leaky faucet, electrical, appliance repair, etc.)

Given the last time it was purchased was 1984, there could be some major repairs needed in the not so distant future such as roof, heater, electric, plumbing.

For building electric I pay about $50/month and for City of Chicago water/sewer/trash I pay approx. $185 every two months. 

At this time I would Sell two of my rental houses in order to Buy my friends two houses, on the lot next door, in a bad neighborhood, because I can get them for $30K under Retail, after a new roof and electric.

Good afternoon gentlemen.I'm own an electrical Company in the valley that sspecializes in rehab and flips.

Rehab would include framing, new electrical, new plumbing, mostly new drywall, full cosmetic rehabs with ARV in the $200 - $250/sq ft range.You can do this yourself if the flipper bought the property on the MLS.

I'm up to Plumbing, Electric, Flooring, Finish work.
